Sourcing Sodium Iodide from China

Sodium iodide: 4% base duty, 0% suspension

Read from the UK Trade Tariff on 1 October 2026, heading 2827 covers chlorides, chloride oxides and hydroxides, bromides and bromide oxides, and iodides and iodide oxides. Sodium iodide has its own line, 2827 60 00 10. The supplied facts contain only this relevant sodium iodide line.

The China duty is 4%, with an autonomous tariff suspension at 0.00 %. The suspension excludes mixtures, preparations and products made up of different components containing sodium iodide. No anti-dumping or countervailing measure is recorded. The tariff attaches import and export waste controls. Confirm their application with your customs broker. For imports into England under waste notification controls, the exporter in China must apply to its competent authority for consent.

Confirm the commodity code from the composition and product specification before claiming the suspension. Do not assume a formulated product uses the plain substance code. For other iodides within the heading, see potassium iodide sourcing.

Specify sodium iodide by assay and water content

Name sodium iodide and its substance identifier, 7681-82-5. State the intended laboratory or industrial use, physical form, assay basis, water content, insolubles and agreed limits for chloride, bromide, iodate and metals. Ask for a batch certificate showing actual results and test methods rather than a generic specification sheet.

Agree sealed inner packaging, protection from moisture and light, batch identification and storage instructions. For Great Britain, establish the UK REACH registration position by confirming the applicable requirements, exemptions and transitional arrangements with the Health and Safety Executive. Obtain an English safety data sheet and applicable hazard labels, as described in the site's published chemical guides.

Worked duty example

Illustrative example, not a quote: Illustrative order: 25 kg of sodium iodide; confirm suspension eligibility before calculation under 2827 60 00 10, 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: match the sodium iodide name, substance identifier and batch number across containers, invoice and analysis certificate.

Analysis: independently check assay, water content and agreed impurities on representative batch samples; compare results on the same assay basis.

Packaging: inspect seals, inner liners, leakage, caking and discolouration; check container weights against the packing list.

Supply documents: compare the safety data sheet, storage instructions and applicable hazard labels with the actual substance supplied. Chemicals must be correctly labelled and packaged before placement on the Great Britain market.

What goes wrong

A high assay figure can conceal a mismatch between dry-basis and as-received results. Moisture uptake, caking, discolouration and an analysis certificate belonging to another batch are reasons to hold the stock for investigation. Agree acceptance criteria and retained samples before shipment.

A mixture quoted as sodium iodide can also lead to an unsupported suspension claim. Obtain the full composition before clearance. Use quality inspection to check packing and batch records, with laboratory analysis arranged separately.
