Sourcing Pyridoxine Hydrochloride from China

Zero duty on unmixed pyridoxine hydrochloride

Heading 2936 covers vitamins, their derivatives and intermixtures. Unmixed pyridoxine hydrochloride falls within the vitamin B6 and derivatives line, 2936 25 00 00. The table distinguishes buying specifications within that same commodity line, rather than separate tariff codes.

Read from the UK Trade Tariff on 30 October 2026, the relevant line carries 0% duty for goods from China, with no listed anti-dumping duty, countervailing duty or suspension. The tariff attaches an export control for waste. Ask your customs broker to confirm its relevance and requirements if the consignment involves waste.

Confirm the commodity code against the composition and presentation. Finished vitamin tablets and capsules are usually food preparations or medicines, rather than this raw-material line. For wider heading coverage, see the thiamine hydrochloride guide.

Specify the hydrochloride salt and intended use

Write pyridoxine hydrochloride explicitly in the purchase specification. Agree food, feed, pharmaceutical or laboratory use, the assay basis, identity test, impurity profile, moisture and particle size. Ask the factory to state whether the powder contains carriers or other added ingredients.

For supplements, check the permitted vitamin forms and finished-product labelling. Confirm any feed-additive authorisation requirements with the relevant feed authority. For pharmaceutical grades, obtain manufacturing-quality evidence and confirm with the medicines regulator whether active substance registration applies to your role and intended use in licensed medicines. A supplier's grade description does not settle these use-specific checks.

Agree a certificate of analysis for each shipped batch, test methods, acceptance criteria and stability evidence supporting the retest or expiry date. Specify sealed inner liners and protection from light and moisture.

Worked duty example

Illustrative example, not a quote: A pilot consignment of sealed drums of pyridoxine hydrochloride; illustrative values under 2936 25 00 00, invoiced at £2,500 free on board, with £2,500 of freight and insurance to the UK. The customs value is £5,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,000, so it is £1,000. 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 and assay: confirm the hydrochloride salt and compare independent batch results with the agreed specification and certificate.

Impurities: check heavy metals, residual solvents where used in manufacture, and microbiology against the agreed grade.

Packing: inspect liner seals, drum damage, moisture ingress and caking; compare batch labels and weights with shipping records.

Traceability: match every drum to its batch certificate and retest or expiry date. Arrange sampling through the inspection process.

What goes wrong

A certificate may describe a different batch or report assay on a different basis from the purchase specification. Material sold simply as a vitamin powder may contain a carrier, while a food-grade batch may be offered against a pharmaceutical-grade order. Require the complete composition and test evidence before accepting a substitution.

Damaged liners and moisture ingress can leave powder caked or contaminated. Photograph affected drums, retain samples and investigate before releasing the batch. If making a finished supplement, do not claim or imply that it treats, prevents or cures disease.
