Sourcing catechol from China

Catechol duty and classification

Read from the UK Trade Tariff on 5 November 2026, heading 2907 covers phenols and phenol-alcohols. The supplied facts do not name catechol separately. Other polyphenols under 2907 29 00 90 carry 4% third-country duty, with no anti-dumping or countervailing measure recorded. The comparison rows distinguish catechol from hydroquinone and resorcinol.

The residual line has a 0% suspension limited to specified substances. Its supplied eligibility text is truncated, so do not assume catechol qualifies. The UK Trade Tariff also attaches an export waste control; confirm its relevance with your customs broker, particularly if the material is waste or will be returned overseas.

Give your broker the chemical identity, composition, grade and intended use to confirm the commodity code and suspension eligibility before shipment. For related products within this heading, see hydroquinone sourcing.

Specify catechol identity and batch quality

Write catechol and its chemical identity explicitly into the purchase specification. Do not accept a quotation described only as dihydroxybenzene or phenolic material. Agree assay, water content, colour, physical form, relevant impurities and analytical methods. Request a batch certificate of analysis and a sample for evaluation in your own process.

Check UK REACH registration responsibilities where annual imports of the substance reach one tonne or more. Before placing chemicals on the GB market, confirm classification requirements with HSE and ensure correct labelling and packaging. Obtain an English safety data sheet and agree handling and storage arrangements before dispatch.

Worked duty example

Illustrative example, not a quote: Illustrative trial order of catechol in 25 kg bags; code subject to confirmation under 2907 29 00 90, invoiced at £1,800 free on board, with £980 of freight and insurance to the UK. The customs value is £2,780. Duty at 4% is £111.20. Import VAT at 20% is charged on the customs value plus duty, £2,891.20, so it is £578.24. Import taxes total £689.44; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £111.20 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the ordered catechol, batch certificate, package labels and safety data sheet; investigate any reference to hydroquinone or resorcinol.

Analysis: compare independently tested assay, water, colour and agreed impurities with the purchase specification and batch certificate.

Packaging: inspect seals, liners and containers for damage, leakage, moisture ingress and contamination before accepting the delivery.

Traceability: match batch markings to shipment documents, photograph discrepancies and keep an identified retained sample.

What goes wrong

A generic chemical description can conceal the wrong substance or grade. A certificate for a different batch leaves the delivery unsupported. Treat discolouration, caking or wet packaging as reasons to investigate against the agreed specification rather than accepting the supplier's explanation without testing.

Another failure is treating a suspension on the residual tariff line as automatic duty relief. Resolve the incomplete eligibility wording before costing the order. Keep disputed batches separate while identity, analysis or packaging discrepancies are assessed.
