Sourcing industrial lauric acid from China

0% duty on relevant industrial fatty-acid lines

Read from the UK Trade Tariff on 29 September 2026, heading 3823 covers industrial monocarboxylic fatty acids, acid oils from refining and industrial fatty alcohols. This guide concerns industrial lauric acid. The table gives candidate non-feed lines distinguished by distillation and the listed fatty-acid criteria. It does not assign a code from the product name alone.

The supplied tariff record shows 0% duty for goods from China on every selected line, with no anti-dumping or countervailing duty, suspension or attached import control. Match the specification to the complete line description, including iodine value and, where specified, degree of split. See the industrial palmitic acid guide for the wider heading.

HMRC says chapter 29 mainly covers separate chemically defined organic compounds. If the supplier offers a chemically defined grade, review its classification rather than automatically using heading 3823. Confirm the commodity code using composition, manufacturing process and intended use.

Specify the lauric-acid cut and batch properties

Specify lauric-acid content and the permitted proportions of other fatty acids, rather than ordering by trade name. Agree acid value, iodine value, moisture, colour, melting range and unsaponifiable matter, with named test methods and acceptance criteria. State whether the material is distilled, its feedstock origin, physical form and intended industrial process.

Ask for a batch certificate of analysis, the fatty-acid chromatogram and a retained sample. Agree packaging liners, closure, batch identification and storage instructions. Trial the sample in your soap or chemical formulation before accepting the production specification.

Importers are responsible for chemical classification. Before ordering a substance you have not previously imported, consider whether UK REACH registration is required. A safety data sheet is required when a hazardous chemical is supplied for use at work. Ask for the proposed supply labels and an English safety data sheet as part of your document review.

Worked duty example

Illustrative example, not a quote: Illustrative order: 15 tonnes of distilled industrial lauric acid meeting this line's criteria under 3823 19 10 70, invoiced at £24,000 free on board, with £2,200 of freight and insurance to the UK. The customs value is £26,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £26,200, so it is £5,240. 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.

Inspection checklist

Composition: compare the batch chromatogram and lauric-acid content with the agreed fatty-acid profile.

Properties: check acid value, iodine value, moisture, colour and melting range against the purchase specification.

Packaging: inspect liners, seals and pallet condition for leaks, water ingress, contamination and damaged bags.

Traceability: match package batch identifiers to the analysis certificate and shipping documents, and retain an arrival sample. Plan sampling through the quality inspection guide.

What goes wrong

A broader fatty-acid blend can meet an acid-value specification while missing the agreed lauric-acid content. Excess moisture, darker colour or a changed melting range can also make a batch unsuitable for the buyer's formulation. Check composition and process performance together.

Another failure is accepting a generic analysis certificate that cannot be matched to the delivered batch. Agree sampling and rejection criteria before dispatch, then compare the arrival sample with the retained approval sample. Do not treat an industrial-grade specification as evidence of suitability for food or feed.
