Sourcing instant dry baker's yeast from China

Duty and organic import controls

Read from the UK Trade Tariff on 4 November 2026, heading 2102 covers active and inactive yeasts, other dead single-cell micro-organisms and prepared baking powders. Instant dry baker's yeast falls within dried baker's yeast, code 2102 10 31 00. The other table rows are classification comparisons, not alternative codes for the same instant dry product.

The dried baker's yeast line carries 0% duty for goods from China, with no anti-dumping or countervailing duty and no suspension listed. The tariff attaches an organic import control. For organic goods from China entering Great Britain, obtain a Great Britain certificate of inspection for each consignment and check the exporter’s control body and export country against the non-UK organic registers.

Confirm the commodity code from the product's active, dried state and baking use. For other yeast products, see the wider yeast and baking powder guide. Confirm with HMRC or your customs broker the VAT treatment of yeast sold as a food ingredient; see UK import duty and VAT.

Specify activity in your bakery recipe

Specify instant dry baker's yeast, the intended dough recipe and whether it is for sweet or lean dough. Agree an activity test using your flour, sugar level, mixing method and dough temperature. Set acceptance criteria for dough rise, dry matter and microbiology, with a batch certificate of analysis.

Agree pack size, vacuum-pack integrity, storage instructions and remaining shelf life on arrival. Approve a production sample in your own recipe before ordering. Confirm with the relevant food authority the retail-pack labelling requirements for sale in Great Britain, including a food name, ingredients with additive functions where applicable, net quantity, date marking and a UK food-business address.

Worked duty example

Illustrative example, not a quote: Illustrative order: 10 tonnes of instant dry baker's yeast in vacuum packs under 2102 10 31 00, invoiced at £30,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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. This assumes the goods are standard-rated for VAT. Most food for human consumption is zero-rated, and animal feed can be too, in which case no import VAT is due, so check the rate for your product in HMRC's VAT Notice 701/14.

Inspection checklist

Activity: test production-batch samples against the approved dough-rise or gassing-power method.

Microbiology: compare dry matter, mould and pathogen results with the agreed specification and batch certificate.

Packaging: inspect sampled packs for lost vacuum, damaged seals, moisture ingress and caking.

Dates and labels: check batch identity, remaining shelf life, storage instructions and approved retail food information.

What goes wrong

A pack can look acceptable while its yeast produces too little gas. Heat during transport and leaking vacuum seals can reduce activity; moisture can cause caking. Recipe differences also make a supplier's activity result difficult to compare with your bakery trial.

Use the same agreed test before shipment and on arrival, retain batch samples and investigate damaged packs before releasing stock. Short remaining shelf life leaves little time to use a slow-moving batch. See quality inspection explained.
