Sourcing Potassium Iodide from China
Potassium iodide from China carries 4% UK duty, with no suspension or trade remedy recorded for its line. Check UK REACH registration coverage and applicable hazard labelling before supply in Great Britain, alongside batch purity and intended use. Cambridge China Bridge sources potassium iodide.
Potassium iodide carries 4% duty
Read from the UK Trade Tariff on 6 November 2026, potassium iodide falls within the other iodides and iodide oxides line, 2827 60 00 90, under heading 2827. Its duty from China is 4%, with no anti-dumping or countervailing measure and no suspension recorded. The table shows purchasing specifications sharing this line, rather than separate tariff subdivisions. The sodium iodide suspension does not extend to potassium iodide.
The tariff attaches import and export waste controls. Waste shipment controls apply only where the material is waste. For potassium iodide from China described as recovered material or waste, ask your customs broker to confirm the applicable import requirement before shipment; this guide does not establish the waste classification or consent route.
Confirm the commodity code against the composition and presentation you will import. For the wider heading, see our potassium bromide guide.

Specify potassium iodide by use and assay
State whether the purchase is for laboratory reagents or industrial processing. Specify potassium iodide identity, assay and whether results are reported on a dry basis or as supplied. Agree moisture, iodate, chloride, bromide, insoluble matter and relevant metal impurity limits with your laboratory. Name the test methods and require a certificate of analysis identifying the supplied batch.
Agree crystal or powder form, acceptable appearance, pack material and closure. Request sealed packaging that protects against moisture and light, and a retained sample. A technical-grade certificate should not be treated as proof of suitability for food or medicinal use.
Confirm with HSE or your customs broker whether UK REACH registration, transitional arrangements or exemptions apply to your imports. Check the registration position before ordering. Ask them to confirm the applicable safety data sheet language and GB hazard labelling requirements, and obtain the documents and labels needed for your supply.
Worked duty example
Illustrative example, not a quote: Illustrative order: 50 kg of laboratory-grade potassium iodide; illustrative FOB and freight values under 2827 60 00 90, invoiced at £2,000 free on board, with £540 of freight and insurance to the UK. The customs value is £2,540. Duty at 4% is £101.60. Import VAT at 20% is charged on the customs value plus duty, £2,641.60, so it is £528.32. Import taxes total £629.92; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £101.60 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity and assay: compare an independently tested batch sample with the agreed specification and certificate.
Impurities: check iodate, moisture, insolubles and the agreed contaminant results, including the stated test methods.
Packing: inspect seals, liners and closures for damage, moisture ingress, caking or discolouration.
Traceability: match container batch markings, certificate, packing list and retained sample through the inspection process.

What goes wrong
An assay result can look acceptable while iodate or another specified impurity fails. Comparing a dry-basis certificate with an as-supplied specification can also hide a moisture problem. Agree the reporting basis and acceptance tests before approving the production sample.
Other failures include damp or discoloured material, damaged closures and certificates referring to a different batch. Hold affected stock for investigation and testing rather than accepting the supplier's grade name as evidence that it meets your specification.

Frequently asked questions
What is the UK import duty on potassium iodide from China?
The supplied tariff record gives 4% for 2827 60 00 90, with no anti-dumping or countervailing duty and no suspension.
Does the sodium iodide duty suspension cover potassium iodide?
No. The suspension is recorded against the separate sodium iodide line. No suspension is recorded for the potassium iodide line.
Do I need UK REACH registration for potassium iodide?
Confirm with HSE or your customs broker whether UK REACH registration, transitional arrangements or exemptions apply to your substance and annual import volume. Check your coverage before ordering.
What should a potassium iodide certificate of analysis show?
The supplied batch, identity, assay, reporting basis, moisture and agreed impurity results with test methods. Verify a batch sample independently against your purchase specification.
