Sourcing Terpin Hydrate from China

Terpin hydrate duty and classification

Read from the UK Trade Tariff on 1 October 2026, heading 2906 covers cyclic alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives. The proposed line for terpin hydrate is 2906 19 00 90, other cyclanic, cyclenic or cycloterpenic alcohols. The supplied tariff data contains no named terpin hydrate line, so confirm this classification before shipment.

The proposed line carries 0% duty for goods from China, with no anti-dumping or countervailing measure and no suspension listed. It attaches Home Office controlled-drug import and export controls and a waste export control. Controlled drugs or precursor chemicals require a licence application. The snapshot does not establish whether these controls apply to pure terpin hydrate; ask your customs broker to confirm the requirement for the actual product.

Confirm the commodity code using the chemical identity, composition and intended supply form. The table contains only the relevant candidate line rather than unrelated substances. For the wider heading, see alpha-terpineol from China. Import VAT is normally 20%; see UK import duty and VAT.

Specify the hydrate, assay and intended use

Order terpin hydrate by its full chemical identity, not a shortened terpin or terpineol description. Agree the hydrate form, assay basis, water content, impurity profile, residual-solvent checks and particle form. State whether assay results refer to the material as supplied or a dried sample. Ask for a batch certificate of analysis with test methods and actual results.

For chemical supply into Great Britain, confirm UK REACH registration coverage with HSE for the intended use and annual import volume. Labels and packaging must be correct before market supply. A safety data sheet is required when a hazardous chemical is supplied for workplace use. If importing it as an active substance for medicines, a UK-based importer must register with the MHRA; confirm the intended regulatory route before ordering.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2 tonnes of terpin hydrate in sealed lined drums under 2906 19 00 90, invoiced at £6,700 free on board, with £1,500 of freight and insurance to the UK. The customs value is £8,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £8,200, so it is £1,640. 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

Identity: match the drum label, purchase specification and batch certificate; arrange an identity test on a representative arrival sample.

Assay and water: compare results against the agreed methods and reporting basis, including water content and specified impurities.

Packaging: check seals, liner condition, net weight and evidence of moisture entry, contamination or caking.

Batch records: match every drum to its production batch and certificate, and retain an arrival sample for comparison.

What goes wrong

A high assay figure can mislead if the supplier reports a dried-sample result while the buyer expects an as-supplied result. Missing water results, an ambiguous chemical name or a generic certificate can leave the buyer unable to establish whether the delivered material matches the agreed hydrate specification.

Damaged liners and broken seals can leave material contaminated or difficult to handle. Hold discrepant drums apart from accepted stock and compare arrival samples with the agreed specification before releasing them. Agree the sampling and testing scope through testing and certification.
