Sourcing acetaldoxime from China
Acetaldoxime from China has a potential UK duty range of 0% to 6%: the named aqueous solution line carries a suspension, while other forms need classification checks. Great Britain buyers should confirm applicable UK REACH requirements with HSE and check chemical classification and safety documentation. Cambridge China Bridge sources acetaldoxime.
Acetaldoxime duty and the aqueous solution line
Read from the UK Trade Tariff on 2 October 2026, heading 2928 covers organic derivatives of hydrazine or hydroxylamine. Acetaldoxime is also called acetaldehyde oxime. Its named aqueous solution line is 2928 00 90 25, identifying chemical substance 107-29-9. Only this named line and the residual line are relevant to this guide; the table therefore contains no unrelated chemicals.
The aqueous solution line has a 6% third-country duty and an autonomous suspension to 0%. Its footnote excludes mixtures, preparations or products made up of different components containing the product. Confirm that the supplied composition meets the named description and suspension conditions. The residual line carries 6%; its suspension names other substances, not acetaldoxime. Neither relevant line shows anti-dumping or countervailing duty in the supplied record.
The tariff attaches dangerous-chemical and waste export controls to both lines, and Home Office controlled-drug import and export controls to the residual line. Ask your customs broker to confirm their relevance to the actual goods from China. HSE states that imports have no PIC notification obligations. Confirm the commodity code, particularly for material outside the aqueous description. See the wider heading guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Acetaldehyde oxime in aqueous solution | 2928 00 90 25 | 6% | None |
| Other derivatives: candidate line for acetaldoxime outside the aqueous description | 2928 00 90 90 | 6% | None |
Specify acetaldoxime identity and solution strength
Write acetaldoxime and acetaldehyde oxime together on the purchase specification, with substance identity 107-29-9. State whether you require an aqueous solution or material supplied without added water. For solutions, define the assay on the supplied solution, its calculation basis and the test method. Agree water content, colour, residual starting material, other impurities, any additives, container material and storage conditions.
Request a batch-specific certificate of analysis and an English safety data sheet where required. Confirm the applicable UK REACH registration requirements and any only-representative coverage with HSE for imports into Great Britain. Classifying and labelling requires scientific competence. Resolve this before ordering rather than treating the supplier's export documents as the complete compliance file.
Worked duty example
Illustrative example, not a quote: Illustrative order: one tonne of acetaldoxime aqueous solution; confirm suspension eligibility under 2928 00 90 25, invoiced at £4,000 free on board, with £980 of freight and insurance to the UK. The customs value is £4,980. Duty at 6% is £298.80. Import VAT at 20% is charged on the customs value plus duty, £5,278.80, so it is £1,055.76. Import taxes total £1,354.56; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £298.80 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the purchase specification, container labels and analysis certificate to acetaldehyde oxime, not acetone oxime or another oxime.
Composition: independently sample the batch and check assay, water content and agreed impurities using the agreed methods; confirm whether results describe the solution or its dissolved substance.
Packing: check closures, seals, leakage and container condition against the agreed packing specification; check labels against the reviewed chemical classification.
Traceability: match batch identifiers across containers, certificates and delivery documents, and retain the agreed sample. Use the inspection guide to define acceptance checks.

What goes wrong
A quotation saying only 'oxime' can leave the identity unresolved. A solution assay can also be confused with the purity of the dissolved substance, making apparently similar offers difficult to compare. These are reasons to agree the full composition and reporting basis before comparing quotations.
Do not assume that every acetaldoxime order qualifies for the aqueous solution suspension. Material supplied in another form, or with additional components, needs its own classification review. Hold batches with inconsistent identity, unexplained assay results or leaking containers until the discrepancy is resolved.

Frequently asked questions
What is the UK import duty on acetaldoxime from China?
The named aqueous solution line, 2928 00 90 25, carries 6% duty with a suspension to 0%. The residual line carries 6%, and its listed suspension does not name acetaldoxime. Confirm the actual composition.
Are acetaldoxime and acetaldehyde oxime the same product?
These names identify the product covered here. Match substance identity 107-29-9 across the specification, analysis certificate and safety data sheet; acetone oxime is a different tariff description.
Does a small acetaldoxime order avoid chemical compliance?
Confirm with HSE how your annual substance imports affect any UK REACH registration requirement. Check classification and labelling and obtain a safety data sheet where required.
What should I put on an acetaldoxime purchase specification?
Specify identity, aqueous or other form, solution strength, assay basis and method, water content, impurity limits, additives, packing and storage conditions. Require a certificate tied to the supplied batch.
