Sourcing unmodified linseed oil from China

Linseed oil duty depends on processing and use

Read from the UK Trade Tariff on 30 September 2026, heading 1515 covers fixed vegetable or microbial fats and oils and their fractions, whether refined or not, but not chemically modified. Its linseed-oil lines carry 2% for crude oil, 4% for other oil for technical or industrial uses excluding human food manufacture, and 8% for other oil. The supplied facts show no anti-dumping or countervailing duty and no suspension on these lines.

The tariff attaches organic import controls to crude oil and the other-use line, and waste import and export controls to all the linseed-oil lines. Organic edible shipments from China need a Certificate of Inspection and accompanying documents; consult your approved UK organic control body. If oil is waste and notification controls apply, the exporter must seek consent from the competent authority in China. Confirm the applicable waste procedure with your customs broker before shipment.

Confirm the commodity code using the processing description, composition and intended use. The table separates edible and industrial crude oil for buying purposes; they share the same code. For related products and the boundary with chemically modified oils, see the boiled linseed oil guide. Do not classify an oil from its sales name alone.

Specify the oil, processing and intended use

State whether you need crude or refined linseed oil, edible stock or technical material for coatings and finishing. Ask the factory to describe extraction, refining and any subsequent treatment, and to declare added oils, solvents or drying agents. Request confirmation that the supplied oil has not been chemically modified.

Agree a fatty acid profile, acid value, peroxide value, moisture, insoluble impurities, colour and odour specification with the supplier and laboratory. For technical stock, compare drying behaviour on your actual substrate with an approved sample. For edible stock, have your food-compliance adviser review the proposed label, packaging and contaminant testing before artwork approval.

Specify sealed packing, filling cleanliness, storage conditions and batch identification. Ask for the analysis certificate for the actual shipment batch rather than a generic product sheet. Organic claims need separate documentary checks; ask your approved UK organic control body which products you can import.

Worked duty example

Illustrative example, not a quote: Illustrative order: 5 tonnes of refined edible unmodified linseed oil under 1515 19 90 00, invoiced at £18,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £19,500. Duty at 8% is £1,560. Import VAT at 20% is charged on the customs value plus duty, £21,060, so it is £4,212. Import taxes total £5,772; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,560 of duty. 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

Identity: compare the shipment batch's fatty acid profile with the agreed specification, and reconcile the processing declaration with the oil ordered.

Freshness: check acid and peroxide values, colour, odour and sediment on an arrival sample. Investigate differences from the retained pre-shipment sample.

Packing: check seals, leaks, drum cleanliness, batch marks and evidence of unsuitable storage. Match container and batch details to the packing list.

Use and documents: check that edible and technical stock remain clearly identified. For organic stock, match the inspection certificate and accompanying documents to the shipment. Agree independent sampling through the quality inspection guide.

What goes wrong

A quote says only linseed oil, while the delivered material is blended, contains drying agents or has undergone a treatment the buyer did not approve. Edible and technical specifications become confused, or a generic analysis sheet hides differences between batches. A drying trial and batch-specific laboratory results help reveal these mismatches.

Oil can arrive with off-odours, increased oxidation, sediment or leaking closures. Record the condition before unloading and retain an arrival sample for comparison. Missing organic paperwork or an unresolved waste description can also delay clearance; settle these questions before the factory dispatches.
