Sourcing cetylpyridinium chloride from China
Cetylpyridinium chloride from China has a standard UK duty of 6%; 0% pharmaceutical relief needs confirmed eligibility. Chemicals supplied in Great Britain must be correctly labelled and packaged. Specify the hydrate form and assay basis before ordering. Cambridge China Bridge sources cetylpyridinium chloride.
Standard duty and conditional pharmaceutical relief
Read from the UK Trade Tariff on 1 October 2026, heading 2923 covers quaternary ammonium salts and hydroxides, alongside lecithins and other phosphoaminolipids. The relevant residual line, 2923 90 00 90, carries a standard duty of 6% for China. The table repeats this code for different purchasing specifications. Our published heading guide describes 0% relief for listed pharmaceutical substances; confirm eligibility rather than relying on a supplier's pharmaceutical-grade description.
The supplied tariff facts record no anti-dumping or countervailing duty on this line. Its autonomous suspension names other substances, not cetylpyridinium chloride. The UK Trade Tariff attaches export controls on dangerous chemicals and waste. These are labelled export controls; ask your customs broker to confirm their relevance to the transaction and any requirements before shipment.
Confirm the commodity code using the chemical identity, hydrate form and complete composition. Ask separately about formulated mixtures or finished mouthwash. See the wider heading guide for other substances and the import duty and VAT guide for the calculation method.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cetylpyridinium chloride, anhydrous raw material | 2923 90 00 90 | 6% | None |
Specify hydrate form and assay basis
Specify cetylpyridinium chloride, also called CPC, by its full chemical identity and whether it is anhydrous or a monohydrate. Agree whether assay is reported on the material as received or on a dried basis. Include water content, related impurities, residual solvents, appearance, solubility and the analytical methods. Request actual batch results rather than a generic specification sheet.
For industrial supply, confirm the UK REACH position with HSE for your intended annual imports. Chemicals supplied in Great Britain must be correctly labelled and packaged. If the intended finished oral-care product is a cosmetic, a qualified safety assessor must check its safety before consumer supply. Agree the ingredient evidence needed with the formulator before approving the raw material.
Worked duty example
Illustrative example, not a quote: Illustrative drum-packed stock order for a small oral-care ingredient supplier under 2923 90 00 90, invoiced at £42,000 free on board, with £1,800 of freight and insurance to the UK. The customs value is £43,800. Duty at 6% is £2,628. Import VAT at 20% is charged on the customs value plus duty, £46,428, so it is £9,285.60. Import taxes total £11,913.60; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £2,628 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the drum labels, invoice and batch certificate to the ordered chemical and hydrate form; arrange an identity test on a retained sample.
Assay and water: compare batch results with the agreed assay basis and water specification; investigate a result reported on a different basis.
Impurities and performance: check agreed impurity and residual-solvent results, then trial dissolution and compatibility in the buyer's actual formulation.
Packing and traceability: inspect seals, liners, moisture damage and caking; match each container to its batch certificate and safety data sheet. Use a written inspection brief.

What goes wrong
A hydrate substitution or an unexplained change in assay basis can make apparently matching certificates unsuitable for the formulation. Other problems include damaged seals, caked material, missing impurity results and certificates that cannot be traced to the delivered batch. Hold affected stock while the factory explains discrepancies and independent testing checks the material.
A raw-material certificate does not establish the suitability of a finished oral-care formulation. Before pursuing a disinfectant application, check the applicable biocidal route with HSE: biocidal products require authorisation for supply in Great Britain. Do not treat the supplier's antibacterial claim as evidence of product authorisation.

Frequently asked questions
What is the UK import duty on cetylpyridinium chloride from China?
The supplied tariff facts show 6% under 2923 90 00 90. Our heading guide describes 0% relief for listed pharmaceutical substances, subject to confirmed eligibility. The suspension recorded on this line names other chemicals.
Should I order anhydrous cetylpyridinium chloride or monohydrate?
Use the form specified by your formulation or laboratory method. Agree the water specification and whether assay is measured as received or on a dried basis before comparing offers.
Does a batch certificate make my mouthwash ready to sell?
For a finished product supplied as a cosmetic, a qualified safety assessor must check its safety before consumer supply. A raw-material batch certificate supplies only part of the formulation evidence.
What should I request from the Chinese factory?
Request the full identity and hydrate form, batch-specific assay and water results, agreed impurity data, analytical methods, a safety data sheet and packing details. Match the delivered batch to those documents.
