Chemotechnique is a family owned and run business since its inception 40 years ago, growing and developing every year, and now the leading manufacturer of open-choice patch test systems in the world.
Chemotechnique is recognised by world-leading Dermatologists as the trusted name in patch testing.
Chemotechnique is 100% dedicated to and focussed on just patch testing products and closely-associated accessory products; with no other product lines or other distractions.
Based in the Skåne region of southern Sweden, Chemotechnique is leading the way globally for patch testing - serving Dermatologists and Allergists globally by supplying their patch test products through a global distribution network of appointed exclusive distributors to over 100 countries, including through AllerDerm Caribbean Ltd as the exclusive distributor for the Caribbean region.
Chemotechnique offer a complete range of high-quality patch test products including over 550 different haptens (also known as allergens), patch test chamber strips (also known as Units), as well as accessory products, and spot tests to indicate the presence of certain metals in common objects.
With emphasis on R&D and working in close co-operation with contact dermatitis research groups such as the International Contact Dermatitis Research Group (ICDRG), the European Environmental and Contact Dermatitis Research Group (EECDRG) and the North American Contact Dermatitis Group (NACDG), Chemotechnique ensure that their product line-up has the ideal composition.
The haptens are produced by Chemotechnique in Sweden under strict pharmaceutical quality control, following the GMP quality management system audited by the Swedish Medical Products Agency. The production processes are certified by the ISO 13485 and ISO 9001 Quality Management systems.
Their high-quality products and reliable service aid Dermatologists and Allergists and their patients in their diagnosis of contact allergy and identification of the problem contact allergens.
The aim of Chemotechnique is not only to provide Dermatologists and Allergists with the necessary patch test haptens and patch test chambers, but also to actively contribute to the development of new hapten tests and the selection of haptens to suit the circumstances of patients, with special emphasis in the field of occupational dermatology.
Much of their work is also focused on the standardisation of patch test haptens, in collaboration with the various national and international clinical research groups, with the highest purity, optimal exact formulation and precise concentration.
THE ORDER PROCESS
The Order Process
We promise you prompt, efficient, transparent, honest and personal communication, whether by:
Telephone +44 7960 315127
WhatsApp +44 7960 315127.
The entire process from initial enquiry to receipt of the product should take a maximum of one month.
The usual sequence of events is as follows:
1. The Dermatologist or Allergist will contact AllerDerm Caribbean by email to email@example.com or to firstname.lastname@example.org to ask about the availability of patch test haptens and/or patch test chamber strips, for their hospital clinic or private practice in the Caribbean region.
Alternatively, a referral will come from the Chemotechnique website at www.chemotechnique.se
or from a Google Search on “patch test manufacturers” or “patch test suppliers Caribbean”.
2. AllerDerm Caribbean Ltd (ADCL) will then respond by email to the potential Client with:
A personalised email reply
A current Chemotechnique Catalogue 2022 of over 110 pages. This is also available on special request as a printed booklet to be posted from Europe.
An ADCL Retail Price List, denominated in USD.
A new ADCL Price List is applicable from 1st February 2022 and is available on request.
A supplementary document “Notes & Recommendations” that comprises several pages of very useful information on patch testing, products, clinical applications, technical information, delivery process, responsibilities, etc.
A new edition is available on request, dated 1st February 2022.
3. The Client Dermatologist/Allergist will doubtless have questions about Hapten Series, Chamber Strips, product availability, delivery lead time, etc, which will be answered promptly and efficiently and reliably by ADCL.
4. The Client will ask for a quotation on the exact cost, including delivery.
5. ADCL will contact Chemotechnique Sweden to request a quotation of the delivery cost from Sweden by courier (such as FedEx, DHL, UPS, etc.).
6. ADCL will return to the Client with the full quotation, including delivery costs.
7. The Client is to formally accept the quotation. Client is to provide an exact delivery address.
8. ADCL will then provide the Client with a Pro Forma Invoice to enable the Client to make the payment to a UK-based commercial bank account for ADCL.
This payment will ideally be in GBP but can be in USD or EUR.
Payment should be by standard inter-bank transfer; however payment by credit card (max value £1,500) is also possible using the SUMUP payment pathway. See www.sumup.co.uk
9. Client makes the payment. This usually takes 2-3 working days to arrive.
10. ADCL acknowledges receipt of the payment.
11. ADCL pays Chemotechnique Sweden.
12. Chemotechnique Sweden then schedule the picking & packing of the items of the order. They inform ADCL of the scheduled date of despatch. This is usually 2-3 weeks after receipt of the payment, though can be shorter or longer depending upon circumstances. ADCL inform the purchaser.
13. Chemotechnique provide ADCL with a tracking number, which is then forwarded to the purchaser.
ADCL will monitor the tracking of the delivery, and will inform the purchaser of developments. The purchaser is advised to also monitor the online tracking service to be automatically notified of any developments.
14. Within usually 3-5 days, the consignment is received in the country of the Client.
At this point the Client (Purchaser) takes over responsibility for the transition of the package through Customs and into their own hands.
It is strongly recommended that the purchaser (or their appointed Customs Agent) is actively involved in contacting the local Customs authority to secure the earliest possible release of the package. The products are packaged in temperature-stabilised materials, but after a week or so their temperature-buffering capabilities will have been exhausted. The products will then become at ambient temperature. If this is above 25 degrees C then there will be temperature stress of at least some of the haptens. Please therefore act to make any retention by Customs as brief a period as possible.

PATCH TEST PRODUCTS
Chemotechnique is 100% focussed and dedicated to the manufacture of patch test products, and the further development of that product line to comply with advances and other changes to the clinical practice of patch-testing Dermatologists and Allergists from around the world.
They manufacture and offer for sale their patch test products through their global network of over 50 national distributors.
The > 550 Haptens manufactured and sold by Chemotechnique are available as either individual haptens, presented in 5ml syringes or in 8ml solution in bottles, or as complete series of individual haptens. These are all available through AllerDerm Caribbean Ltd for Caribbean-based Specialist clinicians.
Each of the >550 haptens can be purchased and supplied individually, though for clients in the Caribbean it is far more economical to order and receive an entire series or more, rather than one or a few individual haptens. This is due to the cost of transportation and the workload involved of payments, import permits, customs clearance, etc.
Series of Haptens
Hapten Series can be either Standard/Baseline Series, or Specialist Series. These Series are simply collections of individual haptens, that have been decided by the leading patch-testing Dermatologists of the country or of the world, and implemented by Chemotechnique.
Popular examples of Baseline/Standard Series that are relevant for Caribbean-based Dermatologists are as follows:
European Baseline Series S-1000 40 haptens
Latin American Series LA-1000 40 haptens
British Standard Series GB-1000 50 haptens
ACDS Core Series AC-1000 90 haptens
North American 100 Series NA-1000 50 haptens
North American 80 Series NAC-80 80 haptens

When purchasing any Series of patch test haptens it is important to also order the patch test Chambers that are an essential part of patch testing procedure. You may already have patch test Chambers from previously, and these may be from Chemotechnique, or they may be some other chambers from some other manufacturer.
If, however, you are starting up a patch test service for your patients, or simply rejuvenating your patch test products in total, then it is recommended that your initial purchase of the patch test Haptens includes an order for a corresponding number of patch test Chamber boxes.
For example, a purchase of the LATAM Series of 40 haptens is adequate for 40 x 150-200 tests = 6,000 to 8,000 tests. Each box of Chamber strips contains 100 strips each of 10 Chambers (test sites) so each box is adequate for 1,000 tests. Therefore it is recommended that the initial purchase of a LATAM Series is accompanied by an order of ideally 6 boxes of Chambers.
At the other end of the testing scale, the recently introduced ACDS Core Series, of 90 haptens, would provide 90 x 150 - 200 tests, so in total 13,500 to 18,000 tests, so would require 14 to 18 boxes of Chambers.
The shelf of the the Chamber boxes is up to 5 years from date of manufacture and is usually 4-5 years from date of delivery, with an absolute minimum of 2 years (so the same as the most stable of the Haptens). Simply put, the Haptens would expire before the Chambers, so there is little to no risk in ordering a corresponding number of Chamber boxes along with your order for the patch test Haptens. If the Chambers are ordered together with the Haptens, then there would be very little if any increase in the cost of the delivery, which is approx. US$250 whether a small package of Haptens or a larger package of Haptens with Chamber boxes. Conversely, ordering Chamber boxes separately later will incur a significant delivery charge (approx. US$250).
There are two different patch test Chamber types manufactured by Chemotechnique and available from AllerDerm Caribbean Ltd for Caribbean-based Specialist clinicians.
IQ Ultra™ Chamber IQ-U
This is the default Chamber used for the Chemotechnique patch test system.
• Each box contains 100 Chamber Strips. Each Chamber Strip contains 10 Chambers (test sites), in 2 parallel rows of 5 chambers. Therefore, each box can do 1,000 patch tests.
See the adjacent pictures.
Consider that for example, the ACDS Core Series is 90 tests and therefore will require the use of 9 Chamber strips. Thus, a box of Chambers will be adequate for 11 patients each tested with only the ACDS Core Series.
• Each chamber has a filter paper incorporated, which eliminates the need to manually add loose filter papers for use with any liquid-based haptens.
• The rim of each chamber has an adhesive layer to optimise adhesion to the skin and so to eliminate leakage. This makes IQ Ultra™ a closed-cell system, enhancing occlusion and confining the test reaction within the parameter of the square-shaped chamber.
• The size of the IQ Ultra™ chamber strip is small to allow the application of multiple Chamber Strips onto the patients’ backs.
• The width of the tape is 52 mm and the length is 118 mm.
• The volume of the chamber is 32 μl and the inside area of the chamber is 64 µl.
• The chambers are made of thin and soft polyethylene foam material to maximise patient comfort.
• The highest quality hypo-allergenic surgical tape is used for the IQ Ultra™.
• Each strip of 10 chambers of IQ Ultra™ is attached to a protective plastic cover with corresponding compartments which makes it possible to re-attach the tape after advance filling of the chambers with the haptens.
• A Reading Plate for IQ Ultra™ / IQ Ultimate™ is supplied in each box.
IQ Ultimate™ Chamber IQ-UL
Practically, the IQ Ultimate™ is suited for more humid and tropical climes (such as the Caribbean region) where sweating/perspiration would be the norm. The IQ Ultimate Chamber is therefore most recommended for use by Caribbean-based Dermatologists.
The IQ Ultimate™ patch test Chamber Strip is based on the widely-used IQ Ultra™ but has three important new features due to it’s new carrier tape.
The three features below are unique for IQ Ultimate™.
Water resistant - permits showering
Elastic - allows normal daily activities
Transparent - facilitates reading of the tests.
The IQ Ultimate Chamber therefore allows the patient to go about their normal daily activities for the 48-hour period whilst the Chambers are attached to the patient’s back during the patch test procedure.
See the adjacent pictures.
• Each box of IQ Ultimate Chamber Strips contains 100 Chamber Strips. Each Chamber Strip contains 10 Chambers (test sites), in 2 parallel rows of 5 chambers. Therefore, each box can do 1,000 patch tests. Consider that for example, the ACDS Core Series is 90 tests and therefore will require the use of 9 Chamber strips. Thus, a box of IQ Ultimate Chambers will be adequate for 11 patients each tested with only the ACDS Core Series.
• Each chamber is made of additive-free polyethylene plastic foam with a filter paper incorporated, thereby obviating the need for the manual addition of filter paper for use with any liquid-based haptens.
• The rim of each chamber has an adhesive layer to optimise adhesion to the skin and to eliminate leakage. This makes IQ Ultimate™ a closed-cell system, enhancing occlusion and confining the test reaction within the square-shaped parameter of the chamber. This feature is crucial in standardised patch testing, which is based on the concept of dose of hapten per unit of area of skin under test. The area has to be exactly defined.
• The chambers are made of thin and soft polyethylene foam material, to maximise patient comfort.
• A hypo-allergenic transparent carrier film is used for the IQ Ultimate™.
• Each strip of 10 chambers of IQ Ultimate™ is attached to a protective plastic cover with corresponding compartments which makes it possible to re-attach the tape, thereby enabling advance filling of the chambers with the haptens.
• The width of the tape is 52 mm., and the length is 118 mm.
• The volume of the chamber is 32 µl and the inside area of the chamber is 64 mm2.
• A Reading Plate for IQ Ultra™ / IQ Ultimate™ is supplied in each box.
The Application Device for IQ Ultra™ makes advance filling of test substances even easier. The device is specifically designed for the IQ Ultra™. It is cost effective and saves nurses/technicians time, as they can prepare test series up to two weeks prior to use. Note though that volatile haptens such as acrylates and fragrances should not be pre-loaded. The device significantly facilitates preloading of multiple IQ Ultra™ or IQ Ultimate™ Patch Test Chamber Strips Units. This is convenient in preparing test series in advance, such as the Baseline Series, for a suitable number of patients.
The design prevents the Chamber Strips from sliding during application of the haptens. The device is equipped with a special function to detach and attach the syringe caps. This eliminates contamination of fingers during the dispensing of haptens. The device has a low weight of only 0.3 kg. The dimensions are (w x h): 43 x 27 cm.
The Reading Plate for IQ Ultra™/IQ Ultimate™ is used to facilitate the reading of a patch test. It contains several pictures of different types and grades of patch test positive reactions, irritant reactions and questionable reactions.
The Chemo Skin Markers™
These are the ideal solution for marking the patch test site or other dermatology uses. The non-sterile marker contains gentian violet ink which provides an effective means for marking the skin. It has a medium round-type tip for distinct marking. It is long lasting and ideal for the marking of patch test sites. The skin friendly ink is non-toxic, non-irritating and non-tattooing. There are 4 pens in the set.
Chemotechnique offer a handheld UV Lamp for easy reading of fluorescent markings, such as from the Chemo Skin Marker - UV™.
The UV Lamp can also be used as a tool for detecting:
• Pityriasis Versicolor
• Tinea Capitis
and when investigating alterations of the patient’s pigmentation.
Chemotechnique also manufacture two Spot Tests which are used by Contact Dermatitis patients to identify the presence of nickel or cobalt in metal objects with which they may come into contact.
Chemo Nickel Test™
Chemo Nickel Test™ is an easy one-step method to detect free Nickel in metallic objects. The test consists of an ammoniacal solution of Dimethylglyoxime (DMG) for the detection of nickel in various metallic objects. DMG produces a bright, reddish-pink insoluble salt with nickel. The Spot test detects free nickel down to a limit of 10 ppm (parts/million). The sensitivity threshold of most nickel allergic patients is above 11 ppm. Some strongly allergic patients will however still react to objects releasing amounts below the threshold of the test. With no known cure for nickel allergy, nickel avoidance is key to protect your skin from allergic reactions. For further information see Chemotechnique website
or contact ADCL at email@example.com
Chemo Cobalt Test™
The Chemo Cobalt Test is an easy one-step method to detect free Cobalt in metallic objects. The test detects free cobalt down to a limit of 8.3 ppm (parts/million). The sensitivity threshold of most cobalt allergic patients is above 10 ppm. Some strongly allergic patients will however still react to objects releasing amounts below the threshold of the test. Chemo Cobalt Test™ consists of Nitroso-R salt for the detection of cobalt in various metallic objects. Nitroso-R salt produces a bright, reddish-pink insoluble salt with cobalt. This test will be of benefit to you in order to avoid exposure to cobalt thereby minimising contact dermatitis caused by cobalt releasing objects.
Chemotechnique have developed and made available to the public their nickel barrier cream Nik-L-Blok, for the every-day skincare routine of nickel-sensitised individuals.
The most innovative barrier cream on the global market.
Designed and created specifically for nickel-sensitive persons.
Nickel is by far the most commonly encountered contact hapten causing Allergic Contact Dermatitis, and so is of great importance to nickel-sensitised persons and to their Dermatologists.
Unfortunately, despite decades of regulation by various authorities in many countries around the world to limit the use of nickel in common every-day articles, it is still very difficult or impossible for members of the public as well as certain categories of workplace professionals to avoid coming into contact with nickel.
Until now, the best and most commonly expressed advice that medical professionals have been able to give to their nickel-sensitised patients has been to “avoid nickel” in order to avoid subsequent signs and symptoms of allergic contact dermatitis.
But now, with the unique Nik-L-Blok product, there is an alternative option for the nickel-sensitive patient or person.
When your skin is exposed to nickel, even nickel in a mix of other metals, free nickel ions penetrate the outer skin layer (stratum corneum) and bind to proteins in the dermis layers. The haptens of zinc ions then become allergens. When the accumulated exposure to nickel surpasses a critical threshold, then the person’s immune system treats the nickel bound in skin proteins as a threat, and then causes the development of the various signs and symptoms of allergy to the nickel. The person is then sensitised against nickel. This sensitisation threshold varies greatly among individuals.
Unlike most other types of allergies (such as respiratory allergy to house dust mites or pollens or animal danders), the signs and symptoms of contact allergy, such as to nickel, are not immediate but are called delayed reactions, usually presenting 12-48 hours after exposure to the substance. Once a person responds with an allergic reaction to nickel, any future exposure of nickel to the skin may result in an allergic reaction.
How Nik-L-Blok works is totally unique. Nickel ions trigger allergic reactions only after having penetrated into the skin. Nik-L-Blok is a revolutionary active skin barrier cream based on a patented chelating formula using the active ingredient DTPA to capture free nickel ions. When the skin is in contact with metal objects containing nickel, the DPTA then blocks the nickel ions from permeating into the skin.
In total, the ingredients in the cream work effectively to protect the skin both internally and externally, thereby preventing the development of allergic reactions such as eczema, dryness, blisters, redness and itching. By using Nik-L-Blok regularly on exposed skin areas that may come into contact with nickel (either in the occupation or work, or in daily life), sensitisation towards nickel will be prevented, as the skin remains protected against nickel-induced Allergic Contact Dermatitis.
or contact ADCL at firstname.lastname@example.org.
AllerDerm Caribbean Ltd is appointed by Chemotechnique of Sweden to be their exclusive distributor for the Caribbean region. This means that ADCL is the sole supplier to consumers in the countries of the Caribbean region. No other distributor company can supply the Chemotechnique products if delivery is to be made to a Caribbean country.
Conversely, ADCL cannot legally supply Chemotechnique products to a Dermatologist/Allergist based in USA or Mexico, and other countries outside the Caribbean region. Chemotechnique will most likely have appointed other companies as exclusive distributors for those other countries.
Similarly, the Chemotechnique distributor in USA cannot supply Chemotechnique products to a Dermatologist or Allergist based in Caribbean, even if that Dermatologist/Allergist is visiting the USA or has a relative or friend or a postal box in USA..... unless that person is a Medical Specialist and is formally registered with the American medical regulatory authorities as practicing in USA.
It may be common practice to obtain products in USA or UK that are unavailable or hard to find or expensive, etc. in a Caribbean country, either by delivery to a post box or even whilst visiting the USA or UK on business or holiday. However, for regulated medical products such as patch test products this is simply not legally permissible. This pathway is therefore not a legal option in order to avoid possibly high Customs charges or other hassles on importing products through normal channels into your own country.
Please also consider the fact that any parallel importation of Chemotechnique patch test haptens, (either commercially or in your personal luggage when travelling), will probably cause the haptens to exceed the temperature-buffering capabilities of any packaging, and will therefore temperature-stress the haptens.
This may lead to their reduced functionality or reduced longevity.
Chemotechnique products are not held in local stock by AllerDerm Caribbean Ltd, for several good reasons:
1. Remaining Shelf Life
2. Re-exportation to another Caribbean country
3. Every purchaser wants something different, whether it be the British Standard Series or the European Baseline Series or the ACDS Core Series, or Cosmetic Series, or Photo-Patch Series, etc.
4. Chemotechnique are geared up to supply product as quickly as possible, usually within 1 month of the first enquiry to the distributor.
Therefore, by not holding local stock, AllerDerm Caribbean Ltd can provide you with the latest production batches of the many products, with the longest possible remaining shelf life, and provide you with exactly what you want.
On occasion one or two haptens in a series (considering that some popular series comprise as many as 80 to 90 haptens) may not be immediately available. If this occurs it is most usually due to a lack of raw material from the supplier of that raw material to Chemotechnique. It can be a complex and time-consuming process to obtain a raw material from an alternative supplier, as there are chemical analyses that would need to be performed to assure the quality and purity of the substance from the new supplier. If a hapten is not immediately available to fulfil a purchaser’s order, then Chemotechnique will inform AllerDerm Caribbean Ltd of the out-of-stock situation and advise when it would next become available, and ask if the purchaser wishes to wait or to receive the rest of the order. ADCL will then contact the purchaser to ascertain if they wish to wait or to receive the rest of their order. Any outstanding hapten(s) would then be supplied by Chemotechnique to the purchaser just as soon as it/they become available. There is no extra delivery cost to the purchaser for this catch-up. Be aware though that there may be (though there logically shouldn’t be!) complications with the Import Permit and Customs costs for the catch-up hapten(s).
Chemotechnique have a Recommended Retail Price (RRP) for all their products globally. Therefore the price should be the same to a Dermatologist/Allergist in USA as it is for Australia or Jamaica or Trinidad & Tobago, etc. However, due to different transportation costs and possible local Customs charges, then there are some differences from country to country, though within the Caribbean region, ADCL adheres to the Chemotechnique RRP.
The Chemotechnique RRP is stated by Chemotechnique in Swedish Kronor (SEK), which ADCL convert to USD at the current (1/2/2022) rate of 9.28 SEK to the USD. This value will be clearly stated in the Quotation and in the Pro Forma Invoice.
Note that the 2021 Retail Price List was created based on a forex conversion of SEK 8.30 to the US Dollar. Therefore with the now prevalent forex rate of SEK 9.28 to the US Dollar this is in effect a 12% devaluation and therefore also a 12% effective price decrease for 2022 compared to 2021 as denominated in USD.
The Chemotechnique Recommended Retail Prices are very competitive, globally.
The Chemotechnique quality is, however, simply outstanding.
For information on prices for any Series or for individual haptens, or chambers or any of the accessory products, please contact AllerDerm Caribbean directly - best by email from your professional email address.
An abbreviated Price List covering the most commonly used and purchased Series can be emailed directly back to you.
Once you have decided which Series you wish to purchase, and how many boxes of Chambers, then just ask us for a Quotation.
Chemotechnique usually increase their prices annually by the rate of inflation in Sweden, which has in recent years been around 2-3%. Unfortunately, this is no longer the case for 2023, as Sweden's rate of inflation during 2022 has been 9.8%, so in line with most other European countries and indeed globally.
Accordingly, Chemotechnique will be increasing their retail prices from 2022 to 2023 by an average of 8%.
Those Chemotechnique prices are quoted by them in SEK, which AllerDerm Caribbean then converts to USD at the prevailing rate at that time of compilation of the new 2023 Retail Price List from AllerDerm-Caribbean. The ~8% price increase in SEK may therefore be more or less than 8% in USD, depending on the SEK:USD exchange rate in late January 2023 compared to late January 2022. At present (8/12/22) that forex difference is less than 1%.
The new 2023 retail prices in USD imposed by Chemotechnique will be applied by AllerDerm Caribbean Ltd from 1st February 2023.
Therefore if you wish to avail yourself of the lower 2022 prices, then your order and your payment need to be made by latest Monday 23rd January 2023 to AllerDerm Caribbean Ltd.
Note that the order & delivery process then takes approx. 2 weeks until the package has arrived in the destination country, but that is normal working weeks, so the upcoming Christmas / New Year break will delay the delivery process accordingly. Chemotechnique will be closed from 23rd December to 3rd January inclusive.
AllerDerm-Caribbean Ltd will not be closing. We remain instantly available for phone calls (+44 7960 315127), though our response time to emails may be a day or so longer than the usual immediate response.
Therefore, you can still pay from your 2023 cost budget to receive Chemotechnique products at their 2022 prices, and with delivery by mid-February 2023.
But please do not wait till the last minute, as these payment processes can sometime be delayed outside our control or influence.
Your latest order and payment date for Chemotechnique products at 2022 prices is 23rd December 2022.
Contact us if you have any questions.
Payment can be made to AllerDerm Caribbean Ltd in USD or if the Client prefers alternatively in EUR or GBP, at quoted rates and prices. We recommend the sending of the funds in GBP, to the UK-located bank; in this way you can control the exchange rate used rather than leaving that to the receiving bank to determine.
Note that any bank charges are for the purchaser to pay, so please ensure that the sum received is the same as the sum sent. Sending payment in GBP should avoid such extra bank charges.
Payment is most usually by inter-bank transfer, to a business bank account at a High Street, UK mainstream bank.
It is also possible for ADCL to take up to £1,500 payment via the purchaser's credit card. We use the SUMUP payment pathway (www.sumup.co.uk). In this way, your capital cost for a patch test hapten series and chambers can be spread over a few up to many months on your credit card, whilst the patch test materials are earning an income for you.

Patch Test Haptens such as are manufactured by Chemotechnique are classified as Diagnostic Tests by medical regulatory authorities. In some countries (such as USA, and in the EU), these are highly regulated, though not as highly regulated as for biological vaccines and chemical-based pharmaceutical products.
The Patch Test Chamber Strips (also known as Units) are classified as Medical Devices, of a low order.
Chemotechnique as a manufacturer is qualified with all the necessary regulatory systems that are mandatory in Sweden and in the EU.
Chemotechnique products, the Haptens and Chambers, are of course registered (approved) by the local national medical regulatory authorities where this is necessary, such as EU, or UK, or USA, etc.
Once a product is registered in a country, then importation of the product can take place unhindered, for any number of events, and recipients, over a long period of time.
In the individual countries of the Caribbean Region such product registration is not necessary. However an Import Permit may be required; or (more likely) it may not be required.
Some Caribbean countries are more proscriptive than others,
and some are more strict in applying their regulations than others. Where we have previous experience or knowledge or information, we will advise the purchaser accordingly.
An Import Permit is a de facto approval by the local national medicines regulatory authority for each individual importation.
The application to the Customs Authority of the individual country can be made by a Customs (Importing) Agent, using information provided by AllerDerm Caribbean Ltd and/or Chemotechnique.
The Dermatologist/Allergist will need to find and appoint a competent and experienced Customs Agent for their importation of the Chemotechnique products. There may be Customs Agents who specialise in medical products.
Customs Tariff Codes
The relevant Customs Tariff Codes for the Chemotechnique products are:
IQ Chambers: 30051000
Plastic Accessories: 39239090
Nickel Spot Test: 38220000
Cobalt Spot Test: 38220000
Information on the Unified Customs Tariff Codes can be found at
This information is useful for any Customs Broker in any country so that they can determine any possible duties & taxes & fees to be levied.
The assessment by the local national Customs authority should always be positive (i.e. importation will be approved) and will then result in the permission to import that product once it arrives. It is usually just a question of time.
It is very important that the Import Permit application and approval is achieved prior to the arrival of the delivery, not when the package has arrived and been held by the Courier company on the instruction of the Customs just because there is no Import Permit for that package. This is important because any delays when the delivery is held up by Customs beyond a day or two whilst waiting for an application and an approval of an Import Permit will lead to a temperature stress of the Haptens. Most usually, the package will not be able to be held refrigerated, and the resultant temperature stress is definitely to be avoided in the heat of the Tropics.
ADCL emphasise that the Client is responsible for the acquisition of any relevant Import Permit. ADCL will assist as much as we possibly can, from afar.
The Client is therefore responsible for Customs clearance, and for any local costs that may be incurred in the importation.
These additional costs may be one or more of the following:
- Customs Agent Fees
- Possible Customs charges - should be zero for medical products
- Possible local Sales Taxes (e.g. GST, VAT, etc.).
- Possible local onward delivery costs, though this should be part of the delivery process for the international courier, though they may engage a local partner service for the local delivery.
Note that products supplied from Chemotechnique cannot be returned for credit. Such regulated medical products cannot be taken back into the stock of the manufacturer and so be made available for resale. One of the good reasons for this is that the temperature history of the products cannot be guaranteed during the transport to the Customs in the destination country, nor during the waiting time whilst awaiting Customs clearance.
If there are any medico-legal regulations or restrictions or limitations on the use of such Patch Test products in the particular country, then the Client is responsible for their own compliance with relevant medico-legal restrictions and requirements of their local country. Most usually, clinical usage of such Patch Test products by any medical Specialist is not restricted.
If there are any questions about commercial matters or medico-legal matters, then please contact ADCL.
We will do our very best to help you.
