Sourcing haematology analyser reagents from China
Haematology analyser reagents from China under heading 3822 carry 0% UK duty across the listed lines. Reagents intended for diagnosis need UKCA or accepted CE marking, MHRA registration and an overseas manufacturer's UK Responsible Person for the Great Britain market. Cambridge China Bridge sources haematology analyser reagents.
Zero duty on the listed reagent lines
Read from the UK Trade Tariff on 1 October 2026, heading 3822 covers prepared diagnostic or laboratory reagents, reagents on a backing and certified reference materials. All listed lines carry 0% duty for goods from China, with no anti-dumping or countervailing measures and no suspensions recorded.
The table shows product examples sharing tariff lines, rather than separate codes for each analyser reagent. Prepared diagnostic reagents may fall under 3822 19 00 90; certified reference materials may fall under 3822 90 00 00. Confirm composition, intended use and certification through finding your commodity code. See the coagulation reagent guide for related products within the wider heading.
For 3822 90 00 00, the UK Trade Tariff attaches veterinary control and a restriction concerning ozone-depleting substances. For Chinese goods, confirm the applicable requirement with your customs broker before shipping, particularly for animal-derived materials. Where an animal-product import information note applies, its conditions must be followed. Importing ozone-depleting substances into Great Britain requires a licence. Do not assume these controls apply identically to every reagent.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Prepared diagnostic diluents for haematology analysers | 3822 19 00 90 | 0% | None |
| Certified reference materials for haematology analyser checks | 3822 90 00 00 | 0% | None |
Specify the analyser and reagent system
State the analyser manufacturer, exact model, reagent channel and intended diagnostic or research use. Specify diluent, lysing reagent or stain separately, with formulation details, bottle size, cap connection, identification system and storage conditions. Ask the factory for compatibility data from the named analyser, lot-specific certificates of analysis, shelf-life evidence and stability after opening.
For diagnostic sale in Great Britain, confirm the applicable marking, registration and Chinese manufacturer representation requirements with MHRA before ordering. For research-only reagents, confirm the appropriate labelling and marketing with MHRA. Ask for English instructions and performance evidence covering the intended use. Agree a sample evaluation on the buyer's analyser before accepting a production batch.
Worked duty example
Illustrative example, not a quote: 500 bottles of haematology analyser reagent, illustrative only under 3822 19 00 90, invoiced at £5,000 free on board, with £300 of freight and insurance to the UK. The customs value is £5,300. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,300, so it is £1,060. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match reagent names, analyser models, channels, bottle connections and identification details to the approved specification.
Batch documents: match each bottle's lot and expiry to its certificate of analysis; check remaining shelf life and evidence supporting storage and open-bottle stability.
Transport: review temperature records against the manufacturer's stated conditions; inspect seals, leakage, contamination and damaged containers.
Performance: evaluate background counts, control recovery and repeatability on the intended analyser against agreed acceptance criteria. Record results alongside the reagent lot through quality inspection.

What goes wrong
A bottle can fit while the reagent chemistry is unsuitable for the analyser. Buyers should investigate unexpected background counts, control drift, altered cell separation or instrument flags during sample evaluation. A compatibility claim without supporting data leaves the laboratory to discover problems after delivery.
Short remaining shelf life, temperature excursions and mismatched lot documents can also prevent acceptance. Agree how suspect batches will be held and investigated. Keep research-only and diagnostic orders clearly identified so the intended use, labelling and supporting documents remain consistent.

Frequently asked questions
What is the UK import duty on haematology analyser reagents from China?
The supplied tariff reading shows 0% duty across heading 3822, with no anti-dumping or countervailing measures and no suspensions recorded. Confirm the line for the actual formulation and use.
Can I sell Chinese analyser reagents for diagnostic use?
For Great Britain, confirm the applicable diagnostic reagent marking, registration and overseas manufacturer representation requirements with MHRA. Check the documents for the exact product before ordering.
Will compatible reagents work with my analyser?
Ask for evidence from your exact model and evaluate samples on that analyser. Check reagent channels, bottle connections, identification details, background counts and control recovery.
What should I check when the reagents arrive?
Check lot certificates, expiry, temperature records, seals and bottle identity. Evaluate performance against agreed criteria before accepting the batch for use.
