Sourcing industrial palmitic acid from China

0% duty on industrial palmitic acid

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 palmitic acid. The selected lines distinguish distilled material from other industrial fatty acids and separate grades meeting listed composition criteria. See the industrial stearic acid guide for the wider heading.

The supplied tariff record shows 0% duty for goods from China on every line of this heading. It lists no anti-dumping or countervailing duty, suspensions or attached import controls. That tariff position does not settle chemical compliance: importers are responsible for hazard classification, and hazardous chemicals supplied for workplace use require a safety data sheet.

Confirm the commodity code using the fatty-acid profile, manufacturing process and intended use. For the selected non-feed lines, the listed criteria include an iodine value below 105g/100g; the qualifying non-distilled line also specifies a degree of split of at least 97%. Do not select a code from the product name alone.

Specify palmitic content and melting behaviour

Specify palmitic acid content and the complete fatty-acid distribution, particularly the stearic and unsaturated fractions. Agree acid value, iodine value, moisture, unsaponifiable matter, colour, odour and melting or solidification behaviour, with named test methods and acceptance limits. State whether you want flakes, beads or powder, and identify the feedstock and whether the material is distilled.

Request a batch certificate of analysis and safety information for the actual grade. Importers of one tonne or more a year of a substance should check their UK REACH position. Ask HSE to review any claimed exemption rather than relying on the supplier's assurance. Agree packaging that protects the material from moisture and contamination, and trial the sample in your intended formulation.

Worked duty example

Illustrative example, not a quote: Illustrative order: 5 tonnes of distilled industrial palmitic acid flakes under 3823 19 10 70, invoiced at £5,550 free on board, with £1,980 of freight and insurance to the UK. The customs value is £7,530. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £7,530, so it is £1,506. 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: check an independently tested batch sample against the agreed palmitic content and full fatty-acid profile.

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

Packaging: check liners, closures, cleanliness, net weight and evidence of water ingress or contamination on arrival.

Traceability: match bag labels, batch references and certificates; review hazard classification and the safety data sheet where required. Arrange quality inspection before dispatch.

What goes wrong

A palmitic-rich blend can be supplied against an order expecting a different fatty-acid profile. Excess stearic or unsaturated material can change melting behaviour and formulation performance. Moisture, discolouration, foreign matter and compacted flakes are further reasons to inspect arrival samples rather than accept a generic certificate.

A sample certificate may describe a different production batch, or the invoice and safety information may use inconsistent product identities. Agree representative sampling, keep retained samples and resolve composition discrepancies before releasing the material into production.
