Sourcing sodium salicylate from China

Sodium salicylate duty and suspension

Read from the UK Trade Tariff on 1 October 2026, sodium salicylate falls within 2918 21 00 00, salicylic acid and its salts, under heading 2918. The base duty for goods from China is 6%, with an autonomous suspension to 0.00 % for salicylic acid and its salts falling under this code. The supplied record lists no anti-dumping or countervailing duty. Confirm the suspension before shipping.

The tariff record attaches a measure labelled “Export control - Waste”. Ask your customs broker to confirm its relevance to the shipment. If material from China is waste subject to notification controls and is being imported into England, the exporter must apply to the competent authority in the country of dispatch for consent. Confirm the applicable waste procedure before ordering recovered or discarded material.

Confirm the commodity code using the substance identity, composition and intended presentation. The table shows purchasing specifications sharing the same tariff line, rather than separate duty categories. For the broader product family, see salicylic acid sourcing.

Specify sodium salicylate identity and use

Name sodium salicylate explicitly, rather than simply “salicylate”. Agree the intended industrial, laboratory or medicinal use; assay method and reporting basis; water content; free salicylic acid; and relevant impurity tests. Specify particle size, appearance, dissolution checks and sealed inner packaging. Request a batch certificate of analysis with actual results and test methods.

For Great Britain, confirm with HSE whether UK REACH registration applies when annual imports of the substance reach one tonne or more and whether an exemption applies. Before supplying the chemical, ensure its labelling and packaging meet the GB CLP rules. If you import sodium salicylate as a medicinal active substance and are UK-based, registration with the Medicines and Healthcare products Regulatory Agency is required.

Worked duty example

Illustrative example, not a quote: 25 kg laboratory trial batch, illustrative only under 2918 21 00 00, invoiced at £2,500 free on board, with £500 of freight and insurance to the UK. The customs value is £3,000. Duty at 6% is £180. Import VAT at 20% is charged on the customs value plus duty, £3,180, so it is £636. Import taxes total £816; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £180 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: verify the sodium salt against the agreed identification method, and match the sample, certificate and package description.

Assay and impurities: compare batch results with the agreed specification, including water content and free salicylic acid; check whether assay is reported on a dried or supplied basis.

Appearance and dissolution: inspect for discolouration, foreign particles and lumps; test dissolution under the agreed conditions.

Packing and traceability: check seals, liners, net weight and batch labels against the packing list and analysis certificate. Arrange independent testing where the intended use needs further verification.

What goes wrong

An order described only as “salicylate” leaves room for the wrong substance. An assay reported on a dried basis can also conceal a mismatch with the buyer’s supplied-basis specification. Generic certificates, unmatched batch numbers and damaged liners make acceptance harder. Hold questionable stock apart until identity and batch results are resolved.

A “pharmaceutical grade” description does not settle the importer’s medicinal active-substance registration duty. Agree the intended use before approving the sample, and keep chemical supply checks separate from the tariff suspension.
