Sourcing bulk povidone-iodine from China

Zero duty on the relevant medicament line

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. Bulk povidone-iodine medicinal solution is a candidate for 3003 90 00 00, subject to its full formula and presentation. The table shows uses of that same tariff line, rather than separate commodity classifications.

The relevant line carries 0% duty for goods from China, with no anti-dumping or countervailing measure and no suspension recorded. The tariff attaches a goods-for-torture-and-repression export restriction. Official guidance confirms that such controls concern exports of relevant goods. Ask your customs broker to confirm whether the attached measure affects your product or any onward export.

Confirm the commodity code using the composition, medicinal use and bulk packaging. Medicines in measured doses or retail packs belong to heading 3004. For wider heading context, see the bulk calamine lotion medicament guide.

Specify the iodine assay and licensed supply route

Write down the complete formula, povidone-iodine content and available iodine acceptance range separately. Agree the assay method, acidity specification, appearance, microbial acceptance criteria and any sterility claim. Identify the intended medicinal use and whether the buyer will further manufacture or fill the solution. Specify container material, closure, storage conditions and the stability evidence supporting the proposed shelf life.

For human-medicine imports from China, ask MHRA to confirm whether the proposed route requires a manufacturer’s licence covering importation and qualified person batch release. Ordinary sale of a human medicine requires a marketing authorisation, and supplying human medicines to businesses requires a wholesale distribution licence. Have the licensed importer agree the product and supply route before ordering; a supplier’s analysis certificate does not replace that work.

Worked duty example

Illustrative example, not a quote: Illustrative order: 500 kg of bulk povidone-iodine medicinal 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 manufacturer, formula, batch identity, analysis certificate and release documents to the actual containers.

Available iodine: arrange independent sampling against the agreed identity and assay methods; do not approve the batch from its brown colour alone.

Containers: check closures, seals, leaks, staining and compatibility evidence for the proposed container and closure.

Arrival condition: compare storage and transport records with the agreed conditions, inspect for sediment or unexpected appearance, and hold discrepant goods for review.

What goes wrong

An order described only as iodine solution leaves room for a different formula or assay basis. Confusing povidone-iodine content with available iodine can produce a batch that matches the supplier’s paperwork but fails the buyer’s specification. Agree both specifications and the test methods before approving a sample.

Other failures include leaking closures, inconsistent batch documents and a filling plan agreed before the licensed importer has reviewed it. Resolve discrepancies before releasing stock. Use factory verification to check the actual production site and testing and certification support to agree the sampling brief.
