Sourcing adipic dihydrazide from China
Adipic dihydrazide from China should be budgeted at 6% UK duty under the residual line, subject to classification confirmation. The supplied suspension does not name it. Great Britain buyers must check their UK REACH route and applicable chemical supply requirements. Cambridge China Bridge sources adipic dihydrazide.
Adipic dihydrazide: budget for 6% duty
Read from the UK Trade Tariff on 2 October 2026, heading 2928 covers organic derivatives of hydrazine or hydroxylamine. The supplied data does not name adipic dihydrazide separately. Residual code 2928 00 90 90 carries 6% duty for goods from China, with no anti-dumping or countervailing duty recorded. Its 0% suspension is limited to other named substances. The table shows purchasing applications under the same provisional residual code, rather than separate tariff lines.
The UK Trade Tariff attaches Home Office controlled-drug import and export controls, dangerous-chemical export controls and waste export controls to this residual line. Confirm their application to the actual material from China with your customs broker before shipment. The Home Office requires licence applications for imports or exports of controlled drugs or precursor chemicals; this does not establish that adipic dihydrazide is controlled.
Confirm the commodity code using the chemical identity, composition and supplied form. A formulated blend needs its own classification review. See the wider oximes and hydrazine derivatives guide for other substances within this heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Adipic dihydrazide for formulation trials, subject to classification confirmation | 2928 00 90 90 | 6% | None |
Specify adipic dihydrazide for your formulation
Specify chemical identity, assay and test method, moisture, particle size, colour, insoluble matter and relevant impurities. Agree sealed packaging, batch identification, storage instructions and a certificate of analysis for each lot. For coating or adhesive work, test the sample in your actual formulation and record dissolution, dispersion and finished-film performance before approving production.
For Great Britain, confirm with HSE the UK REACH registration position for your intended annual imports, including whether only-representative coverage applies. Check the applicable chemical classification and safety data sheet. Classification and labelling must be handled by someone scientifically competent; hazardous chemicals supplied for workplace use require a safety data sheet.
Worked duty example
Illustrative example, not a quote: Illustrative one-tonne trial consignment of bagged adipic dihydrazide under 2928 00 90 90, invoiced at £2,500 free on board, with £980 of freight and insurance to the UK. The customs value is £3,480. Duty at 6% is £208.80. Import VAT at 20% is charged on the customs value plus duty, £3,688.80, so it is £737.76. Import taxes total £946.56; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £208.80 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the order, bag labels, certificate of analysis and safety data sheet to adipic dihydrazide and the delivered batch.
Laboratory: independently check assay, moisture, particle size and agreed impurities using the contracted methods.
Packing: inspect seals, liners, water damage, contamination and hard lumps; compare labels with the applicable chemical classification.
Application: repeat the approved formulation trial with an arrival sample. Use the quality inspection guide to organise sampling and release records.

What goes wrong
Watch for powder that meets the headline assay but misses the agreed moisture or particle-size specification. Caking, contamination or inconsistent dissolution can make a delivered batch unsuitable for your process. Keep a retained approved sample and hold disputed material until the agreed tests resolve the difference.
Do not assume another substance's suspension applies to adipic dihydrazide. Ask your broker to resolve the attached controls. HSE says there are no prior-informed-consent notification obligations for imports, but that does not settle other chemical requirements. If the consignment is waste destined for England under notification controls, shipment needs consent from the dispatch, destination and transit authorities.

Frequently asked questions
What is the UK import duty on adipic dihydrazide from China?
Budget for 6% under residual code 2928 00 90 90, subject to classification confirmation. The supplied suspension names other substances, and no anti-dumping or countervailing duty is recorded.
Do I need UK REACH registration for adipic dihydrazide?
For Great Britain, confirm with HSE whether registration or only-representative coverage is needed for your intended annual imports. Confirm the route before ordering.
What should an adipic dihydrazide specification include?
Chemical identity, assay and method, moisture, particle size, colour, insoluble matter, relevant impurities, packaging and batch documents. Include acceptance tests in your actual formulation.
Does the tariff control mean adipic dihydrazide needs a drug licence?
The supplied residual line carries a Home Office import control. It does not establish that adipic dihydrazide needs a licence. Ask your customs broker to confirm the requirement for the exact material.
