Sourcing methyl cyanoacetate from China

Methyl cyanoacetate duty and classification

Read from the UK Trade Tariff on 1 October 2026, heading 2926 covers nitrile-function compounds. Methyl cyanoacetate with a purity by weight of 97% or more appears under 2926 90 70 32, alongside ethyl cyanoacetate. The supplied record shows 0% duty for goods from China, no suspension on that named line, and no anti-dumping or countervailing duty.

The residual line 2926 90 70 90 also records 0% duty and suspension entries, including one covering alkyl or alkoxyalkyl esters of cyanoacetic acid; its suspension excludes mixtures and preparations. Both relevant lines attach dangerous-chemical export and waste-export controls. These are labelled export controls in the supplied record. Ask your customs broker to confirm their relevance and any requirements for your shipment from China.

Confirm the commodity code using methyl cyanoacetate's identity, composition and batch purity. Do not automatically place a formulated mixture on the residual line. The table repeats the relevant codes for purchasing uses, rather than identifying separate tariff subdivisions. Read the related ethyl cyanoacetate guide for the shared named line.

Specify methyl cyanoacetate by composition

Specify methyl cyanoacetate rather than ethyl cyanoacetate, and record the substance identifier 105-34-0. Agree assay by weight, the analytical method, water content, acidity, residual solvents and appearance. Request a certificate of analysis for the actual production batch, including measured results rather than a generic specification. Agree drum material, closure, sampling arrangements and storage instructions.

Confirm with HSE whether your planned imports require UK REACH registration or can be covered through an only representative. Chemical classification is the supplier's responsibility, including importers. Everyone in the supply chain must ensure correct labelling and packaging before placing chemicals on the market. If the chemical is hazardous and supplied for use at work, a safety data sheet is required.

Ask for an English safety data sheet matching the supplied composition. For first supply, confirm with HSE the applicable requirements for providing it, including charges and delivery format. Compare the identity and handling instructions with the batch certificate and packaging before accepting the shipment.

Worked duty example

Illustrative example, not a quote: Illustrative shipment of drums for a small-business process trial under 2926 90 70 32, invoiced at £2,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £4,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,000, so it is £800. 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 methyl cyanoacetate, the substance identifier and batch reference across the purchase order, certificate, safety data sheet and drum labels.

Analysis: have representative samples checked for assay, water, acidity and residual solvents against the agreed methods and acceptance limits.

Drums: check seals, closures, leakage, external contamination and the recorded net contents; photograph damage before moving affected drums.

Traceability: match every delivered batch to its analysis certificate and retain samples for comparison. Use the quality inspection guide to organise acceptance checks.

What goes wrong

A headline purity result can conceal unsuitable water, acidity or solvent residues. An analytical purity result may also be presented without explaining whether it establishes purity by weight. These gaps can make the material unsuitable for your process or leave the named tariff description unsupported.

Another failure is paperwork naming ethyl cyanoacetate while the order specifies methyl cyanoacetate. Mixed batch references and damaged closures also undermine acceptance. Hold affected stock, obtain corrected batch documents and compare retained samples before releasing it into production.
