Sourcing acetone oxime from China

Acetone oxime duty and purity conditions

Read from the UK Trade Tariff on 2 October 2026, heading 2928 covers organic derivatives of hydrazine or hydroxylamine. Acetone oxime, identified by CAS number 127-06-0, has a named line, 2928 00 90 18, for purity by weight of 99% or more. The comparison rows identify other oximes, not alternative names for acetone oxime.

For Chinese-origin goods, that line carries 6% duty with an autonomous suspension to 0%. The suspension excludes mixtures, preparations and products made up of different components containing the substance. The supplied tariff record shows no anti-dumping or countervailing measure. It attaches dangerous-chemical and waste export controls; ask your customs broker to confirm their relevance to the planned movement. HSE states that there are no PIC notification obligations for imports.

Give your broker the chemical identity, composition and batch assay to confirm the commodity code and suspension claim before dispatch. Do not assume a lower-purity grade or formulated solution qualifies for the named line. See the wider oximes and hydrazine derivatives guide for related substances.

Specify acetone oxime identity and assay

Write acetone oxime and CAS number 127-06-0 into the purchase specification. State the assay on a weight basis, water content, colour, agreed impurity limits and analytical methods. Ask the factory to identify residual starting materials and provide a certificate of analysis tied to each production batch. Agree packaging, storage conditions and shelf life.

For Great Britain, establish the UK REACH route before ordering. Use the wider guide to prepare questions, and confirm the applicable registration threshold and any only-representative coverage with HSE. Obtain an English safety data sheet where required and check the current GB chemical classification. Ask for batch evidence rather than accepting a generic specification sheet.

Worked duty example

Illustrative example, not a quote: 15 tonnes of acetone oxime; illustrative order, values are not a quotation under 2928 00 90 18, invoiced at £21,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £23,500. Duty at 6% is £1,410. Import VAT at 20% is charged on the customs value plus duty, £24,910, so it is £4,982. Import taxes total £6,392; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,410 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match acetone oxime and its chemical identifier across the order, container labels, safety data sheet and batch certificate.

Assay: arrange independent testing of a representative batch sample against the agreed purity, water content and impurity limits; confirm that the reported basis matches the tariff description.

Packaging: check seals, closures, damage and batch markings on arrival. Compare labels and handling instructions with the safety data sheet.

Traceability: match delivered containers to the tested batch and retain the sampling record. Use the quality inspection guide to agree the inspection scope.

What goes wrong

A quoted assay can refer to a different reporting basis from the agreed weight-based purity. A certificate may describe a sample rather than the delivered batch, or a supplier may offer a different oxime under a loose trade description. These are reasons to hold the batch for identity and assay checks.

A suspension claim can fail when the material does not meet the named purity condition or is a mixture. Agree composition and testing before shipment, and reconcile the results with the customs declaration. Keep any batch with damaged seals or mismatched documents separate until the discrepancy is resolved.
