Sourcing sodium propionate from China

Sodium propionate: 4% duty

Read from the UK Trade Tariff on 1 October 2026, heading 2915 covers saturated acyclic monocarboxylic acids and their derivatives. Sodium propionate falls within the supplied line for propionic acid, its salts and esters, 2915 50 00 00. This is the only supplied commodity line relevant to sodium propionate.

The supplied line carries 4% duty for goods from China, with no listed anti-dumping or countervailing duty and no listed suspension. The UK Trade Tariff attaches “Export control - Waste”. This is an export-labelled measure; ask your customs broker to confirm its relevance if the material is waste or a rejected batch is being returned.

Confirm the commodity code using the actual composition and product description, particularly for blends. See the wider acids and acetates guide for the rest of the heading and UK import duty and VAT for the calculation method.

Specify sodium propionate for its intended use

State whether you need food-grade sodium propionate or material for a laboratory or industrial process. Agree identity, assay and its reporting basis, moisture, insoluble matter, particle size and packaging. Ask for the actual batch certificate of analysis, test methods and a retained sample. Do not accept a generic specification sheet as the batch result.

For food use, check the permitted food category and quantity before ordering. Official guidance says most additives are restricted to certain foods and specific quantitative limits. Ask the supplier for evidence against the applicable food-additive specification rather than relying on the words “food grade”.

For chemical supply in Great Britain, review your UK REACH role and intended use. HSE says food and foodstuff additives have tailored provisions, so do not assume that an industrial-use registration assessment also answers the food-use question.

Worked duty example

Illustrative example, not a quote: Illustrative pallet order of bagged sodium propionate under 2915 50 00 00, invoiced at £2,500 free on board, with £980 of freight and insurance to the UK. The customs value is £3,480. Duty at 4% is £139.20. Import VAT at 20% is charged on the customs value plus duty, £3,619.20, so it is £723.84. Import taxes total £863.04; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £139.20 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match sodium propionate on the order, certificate, invoice and bags; check that another propionate salt has not been substituted.

Batch analysis: compare assay, moisture and insoluble matter with the agreed specification and reporting basis; arrange independent testing where results need confirmation.

Packaging: inspect liners, seals and bags for tears, water staining, contamination and hard lumps; photograph defects before moving the stock.

Traceability: match bag batch references to the certificate and packing list, and retain representative samples. Agree the scope of testing and certification before shipment.

What goes wrong

A supplier offers technical material against a food-grade enquiry, supplies a certificate for a different batch or reports assay on a different basis from the agreed specification. These are acceptance risks even when the product name matches. Agree the documents and test methods before approving the order.

Damp or damaged bags can leave powder lumpy or contaminated. Keep affected stock separate while assessing it, record the bag and batch references, and resolve the cause before accepting replacement material. Trial the delivered material in your process rather than relying only on the approved sample.
