Sourcing BTAC from China
Benzyltrimethylammonium chloride from China carries a standard UK duty of 6% under the residual quaternary ammonium line. Its listed suspension covers other substances. Check your UK REACH position and chemical labelling duties before supply. Cambridge China Bridge sources benzyltrimethylammonium chloride.
Standard duty is 6%
Read from the UK Trade Tariff on 1 October 2026, heading 2923 covers quaternary ammonium salts and hydroxides, lecithins and other phosphoaminolipids. Benzyltrimethylammonium chloride is a candidate for the residual line 2923 90 00 90, with standard China-origin duty of 6%. The supplied facts list no anti-dumping or countervailing duty. The table shows purchasing uses of the same residual line, rather than separate commodity classifications.
The residual line's 0.00 % suspension names tetrapropylammonium hydroxide solution and tetrakis dimethylditetradecylammonium molybdate, rather than benzyltrimethylammonium chloride. It also attaches dangerous-chemical export and waste-export controls. Ask your customs broker to confirm the requirements for your material and shipment. Waste shipment controls apply only where the material is waste; investigate recovered or discarded material before ordering.
Confirm the commodity code using the complete chemical identity, composition and supplied form. Do not assume a solution or formulated blend follows the neat substance. For the wider heading, see tetrabutylammonium bromide and related salts.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |

Specify benzyltrimethylammonium chloride precisely
Write benzyltrimethylammonium chloride, abbreviated here as BTAC, in the purchase specification. Distinguish it from benzyltriethylammonium chloride and benzalkonium chloride. Agree the supplied form, assay method, moisture limit, residual solvents and relevant impurities. Ask whether the assay is reported on the material as supplied or on a dry basis.
Request a batch-specific certificate of analysis, the test methods and a retained sample. Agree sealed packaging, batch identification and storage instructions. Test a sample in your own process before approving the production batch; a matching assay alone does not establish suitability.
Confirm your UK REACH position with HSE for the planned annual import volume before shipment. Registration is assessed per substance and legal entity. Chemicals must be correctly labelled and packaged before being placed on the Great Britain market. A safety data sheet is required when a hazardous chemical is supplied for workplace use.
Worked duty example
Illustrative example, not a quote: Illustrative order: 500 kg of benzyltrimethylammonium chloride under 2923 90 00 90, invoiced at £2,500 free on board, with £1,800 of freight and insurance to the UK. The customs value is £4,300. Duty at 6% is £258. Import VAT at 20% is charged on the customs value plus duty, £4,558, so it is £911.60. Import taxes total £1,169.60; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £258 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the purchase specification, batch certificate, safety data sheet and package labels to benzyltrimethylammonium chloride.
Assay and moisture: test representative batch samples against the agreed methods and acceptance limits; check the reporting basis.
Packaging: check seals, liners, damage, leakage and signs of dampness or caking before accepting the delivery.
Traceability: reconcile batch marks and delivered weights with the certificate and packing list; retain samples and record discrepancies.

What goes wrong
Similar chemical names can conceal a substitution. A dry-basis assay can also obscure the concentration actually delivered. Missing moisture results, unexplained solvent residues or a generic certificate make it difficult to judge whether a batch meets the agreed specification.
Quarantine material with mismatched identity, damaged packaging or unexplained analytical results. Ask for a documented investigation and test the affected batch before release. Use quality inspection to agree sampling and acceptance checks before dispatch.

Frequently asked questions
What is the UK import duty on benzyltrimethylammonium chloride from China?
The supplied tariff facts give a standard rate of 6% for residual code 2923 90 00 90, with no listed anti-dumping or countervailing duty. Its named suspension does not cover this substance.
Does benzyltrimethylammonium chloride need UK REACH registration?
Confirm your UK REACH position with HSE for the planned annual import volume. Registration is assessed per substance and legal entity; check how your imports are covered before shipment.
What should the supplier's certificate of analysis show?
Ask for the batch identity, assay, reporting basis, moisture, relevant impurities and test methods. Compare the results with your purchase specification and independently test the batch where needed.
Can I accept benzyltriethylammonium chloride instead?
Treat it as a proposed material change. Require a revised specification and process trial before approval; a similar name does not establish equivalent performance.
