Sourcing white chocolate couverture from China

Listed duty and the milk import prohibition

Read from the UK Trade Tariff on 30 September 2026, heading 1704 covers sugar confectionery, including white chocolate. White chocolate under 1704 90 30 00 carries 8% duty for goods from China, with no anti-dumping or countervailing duty and no suspension recorded. The table shows different supply forms within the same commodity line.

The tariff attaches a restriction on entry into free circulation and an organic import control. Higher-risk food covered by the applicable restriction must enter through authorised border control posts for controls. Ask your customs broker to confirm whether your recipe and origin trigger that restriction and what the organic control requires. These checks do not override the prohibition on confectionery from China containing milk.

Confirm the commodity code from the complete recipe rather than the supplier’s description of couverture. The listed duty does not establish permission to import. See the wider sugar confectionery guide for other products within this heading.

Specify the couverture before discussing an order

Start with the complete recipe, including cocoa butter, sugar, milk powder, milk fat, emulsifiers and flavourings. Obtain ingredient origins and the manufacturing location. For milk-containing white chocolate couverture from China, stop the GB purchase process because official guidance prohibits its import.

For specification assessment, record cocoa butter content, total fat, sweetness, colour, melt viscosity and the intended use, such as moulding, dipping or ganache. Agree the supply form, packaging, storage instructions and an approved reference sample. A dairy-free reformulation needs a fresh assessment of its identity, classification and import route.

Worked duty example

Illustrative example, not a quote: Illustrative pallet order of white chocolate couverture buttons, for duty arithmetic only; prohibited milk-containing goods must not be ordered for GB import under 1704 90 30 00, invoiced at £9,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £10,500. Duty at 8% is £840. Import VAT at 20% is charged on the customs value plus duty, £11,340, so it is £2,268. Import taxes total £3,108; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £840 of duty. The import duty and VAT guide explains each step. HMRC's VAT Notice 701/14 lists confectionery among the exceptions that are standard-rated even though most food is zero-rated, so the 20% VAT shown applies.

Inspection checklist

Recipe: compare the ingredient declaration and batch analysis with the approved specification, especially milk ingredients and substitutions for cocoa butter.

Performance: assess melting, flow, tempering and release from your mould against the reference sample using your own process.

Condition: check for fused buttons, bloom, unusual odours, damaged liners and moisture; record transport and storage conditions.

Documents: check batch identity and traceability. For any separately confirmed lawful supply, check English labels for ingredients, emphasised allergens, net quantity, best-before date and UK business address.

What goes wrong

The central purchasing error is treating a tariff code and duty rate as import approval. Official guidance prohibits confectionery from China containing milk. Do not pay a deposit on the assumption that a low milk content, a different pack format or the word couverture removes that prohibition.

In technical assessment, an attractive sample can still perform poorly in production. Variable fat composition changes flow and setting, heat exposure fuses drops, and odour transfer spoils flavour. Resolve these specification issues only alongside a confirmed lawful supply route.
