Sourcing diethylhydroxylamine from China
Heading 2928 has rates from 0% to 6%, but diethylhydroxylamine under the residual line carries 6%; its named suspension does not cover this substance. Great Britain buyers must check UK REACH registration and chemical classification, labelling and packaging before supply. Cambridge China Bridge sources diethylhydroxylamine.
Diethylhydroxylamine duty and tariff controls
Read from the UK Trade Tariff on 2 October 2026, heading 2928 covers organic derivatives of hydrazine or hydroxylamine. For diethylhydroxylamine, check residual code 2928 00 90 90 against the actual composition. The other table rows are comparison substances, not alternative codes for diethylhydroxylamine. See the wider heading guide.
The residual line carries 6% duty for goods from China, with no anti-dumping or countervailing measure recorded. Its 0% suspension names other substances and does not cover diethylhydroxylamine. The tariff attaches Home Office controlled-drug import and export controls, dangerous-chemical export control and waste export control. Confirm their applicability and any required declaration documents with your customs broker before shipping from China.
Confirm the commodity code using the chemical identity, full composition and supplied form. Do not assume that a formulated treatment containing diethylhydroxylamine has the same classification as the substance. For the calculation method, see UK import duty and VAT.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Diethylhydroxylamine, subject to confirmation of composition | 2928 00 90 90 | 6% | None |
| Comparison only: bis(methoxyethyl)hydroxylamine, a different substance | 2928 00 10 00 | 0% | None |
| Comparison only: isopropylhydroxylamine, a different substance | 2928 00 90 30 | 6% | None |
| Comparison only: butanone oxime, a different substance | 2928 00 90 70 | 6% | None |
Specify diethylhydroxylamine concentration and impurities
State whether you want undiluted diethylhydroxylamine or an aqueous solution. Specify assay, the basis on which concentration is reported, water content, colour, relevant impurities and the analytical method. Request the full composition rather than accepting a trade name as the specification.
Agree drum material, closure, net contents, storage instructions and a certificate of analysis for each batch. Ask for an English safety data sheet matching the supplied concentration. Great Britain importers should ask HSE to confirm the UK REACH registration requirements for their annual imports and whether coverage through an only representative is available.
Before placing the chemical on the Great Britain market, address classification, labelling and packaging. A safety data sheet is required when a hazardous chemical is supplied for workplace use. Check the factory's batch testing and traceability through factory verification.
Worked duty example
Illustrative example, not a quote: Illustrative small trial consignment of diethylhydroxylamine in sealed drums under 2928 00 90 90, invoiced at £4,000 free on board, with £1,107 of freight and insurance to the UK. The customs value is £5,107. Duty at 6% is £306.42. Import VAT at 20% is charged on the customs value plus duty, £5,413.42, so it is £1,082.68. Import taxes total £1,389.10; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £306.42 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the product name, composition and batch reference across the order, analysis certificate, safety data sheet and drum labels.
Analysis: test a representative sample for diethylhydroxylamine assay, water content and the agreed impurities; use the agreed reporting basis.
Packing: check closures, seals, leaks, corrosion, net contents and legible labels against the approved packing specification.
Documents: check registration coverage where required and resolve the tariff control flag with the broker before dispatch; plan checks using the inspection guide.

What goes wrong
A quotation for concentrated material can become a delivery of diluted solution when the order omits the concentration basis. An analysis certificate may report a result using a different method from the agreed acceptance test. Specify both the composition and the test method before approving production.
Another risk is claiming a suspension intended for a differently named hydroxylamine derivative. Check the exact substance against the suspension wording. Hold leaking drums or batches with inconsistent identity documents pending investigation rather than releasing them into use.

Frequently asked questions
What is the UK import duty on diethylhydroxylamine from China?
The supplied tariff facts show 6% under residual code 2928 00 90 90. Its suspension does not name diethylhydroxylamine. No anti-dumping or countervailing duty is recorded; confirm classification for your composition.
Do I need UK REACH registration for diethylhydroxylamine?
For Great Britain, ask HSE to confirm the registration requirements for your annual imports and whether appropriate only-representative coverage is available. Check your coverage before ordering.
Can I buy diethylhydroxylamine as an aqueous solution?
Specify the concentration, reporting basis, water content and full composition. Match the safety data sheet and acceptance tests to that solution, and confirm its commodity code.
Does the tariff flag mean diethylhydroxylamine needs a drug import licence?
The residual code carries a Home Office control flag. Confirm whether it applies to your exact chemical with your broker and the Home Office; the flag alone does not establish a product-specific licence requirement.
