Sourcing bulk antiseptic solutions from China

Zero duty for bulk medicinal mixtures

Read from the UK Trade Tariff on 14 October 2026, heading 3003 covers mixed medicaments for therapeutic or prophylactic use, without measured doses or retail packaging. For bulk chlorhexidine-cetrimide medicinal solutions, the relevant residual line is 3003 90 00 00, subject to confirmation of composition and presentation. The table shows purchasing variants sharing this line, rather than separate tariff subdivisions.

The supplied tariff record gives 0% duty from China, with no anti-dumping or countervailing measure and no suspension listed. It attaches a goods-for-torture-and-repression export restriction to this line. Ask your customs broker to confirm its relevance to the exact formulation and any onward export; the attached description concerns exports rather than an import licence for this antiseptic.

Confirm the commodity code using the complete formula, medicinal purpose and bulk packaging. Measured-dose or retail-packed medicines belong under heading 3004. For related coverage within the wider heading, see bulk povidone-iodine medicaments.

Specify the chlorhexidine-cetrimide formula

State the chlorhexidine salt, cetrimide identity, target assay for each active ingredient and the basis used to express concentration. Distinguish concentrate from solution supplied at its intended use strength. Agree the solvent, excipients, appearance, acidity, impurity limits, microbial specification and test methods. Ask for stability evidence covering the proposed container, closure and transport conditions.

Define the intended medicinal use before approving a sample. Some products sit near the boundary between medicines and biocides, so seek regulatory advice if status is uncertain. For human medicines imported from China, confirm the applicable import licensing and batch-release route with the MHRA first. For ordinary authorised sale as a human medicine, a marketing authorisation is needed. Agree the applicable authorisation route before ordering.

Worked duty example

Illustrative example, not a quote: Illustrative order: 500 kg of bulk chlorhexidine-cetrimide medicinal antiseptic solution under 3003 90 00 00, invoiced at £30,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £31,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £31,500, so it is £6,300. 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

Batch documents: match the factory, formula, batch identity and analysis certificate to the order; check the manufacturing evidence and release documents required by the licensed importer.

Active ingredients: arrange independent identity and assay checks for chlorhexidine and cetrimide separately, using the agreed concentration basis and methods.

Solution condition: inspect for unexpected colour, sediment, cloudiness or separation, and compare laboratory results with the agreed acidity and microbial specification.

Containers: check seals, leakage, container compatibility, batch labels and storage records on arrival. Keep suspect batches separate pending review. Use the quality inspection guide to agree the inspection scope.

What goes wrong

A quotation may describe chlorhexidine without identifying its salt, or express active content on a different basis from the buyer's specification. A concentrate can also be mistaken for a solution ready for its intended use. Resolve these differences in the signed formula and analysis methods before production.

Appearance alone cannot establish active content or microbial quality. Missing batch records, leaking closures or unsupported transport conditions leave the buyer without enough evidence to accept the batch. Confirm with the MHRA what import licensing and batch-release arrangements apply to the human medicine rather than relying on the supplier's analysis certificate alone.
