Para-toluenesulphonamide duty and suspension
Heading 2935 covers sulphonamides. Para-toluenesulphonamide falls within the toluenesulphonamides line, 2935 90 90 20. The table shows specification examples sharing this commodity line, rather than separate tariff classifications. For the wider heading, see sulphonamides.
Read from the UK Trade Tariff on 23 November 2026, this line carries 6% duty for goods from China and an autonomous suspension to 0%. The suspension excludes mixtures, preparations and products made up of different components containing these substances. The supplied record lists no anti-dumping or countervailing duty for this line.
The tariff record attaches export controls on dangerous chemicals and waste. The dangerous-chemical regime covers certain hazardous chemicals; ask your customs broker to confirm the requirements applicable to the exact consignment and any subsequent return. Confirm the commodity code using the substance identity, composition and intended presentation.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Para-toluenesulphonamide, industrial-use specification | 2935 90 90 20 | 6% | None |
Specify the para isomer and batch quality
Write para-toluenesulphonamide explicitly in the purchase specification. Agree the substance identifier, intended use, assay method, permitted other isomers, related impurities, water content, residual solvents, particle size and appearance. Ask for a batch-specific certificate of analysis and a retained sample. Define whether assay is reported on a dry basis or as received.
For industrial use in Great Britain, confirm applicable UK REACH registration requirements and any exemptions with HSE. Confirm your registration route before ordering. Arrange a competent review of chemical classification. Importers share responsibility for correct labelling and packaging before placing the chemical on the market.
Worked duty example
Illustrative example, not a quote: Illustrative order: 5 tonnes of industrial-use para-toluenesulphonamide under 2935 90 90 20, invoiced at £21,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £24,000. Duty at 6% is £1,440. Import VAT at 20% is charged on the customs value plus duty, £25,440, so it is £5,088. Import taxes total £6,528; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,440 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: check the purchase order, container labels and analysis certificate all identify the para isomer and the same batch.
Analysis: independently check assay, other isomers, moisture and agreed impurities using the specified methods.
Condition: compare colour, particle size and caking with the approved sample; inspect seals, liners and moisture protection.
Documents: check batch traceability, the safety data sheet, your UK REACH route and the basis for claiming the tariff suspension. Use the quality inspection guide to plan sampling.

What goes wrong
Risks include receiving an isomer blend against a para-only specification, accepting an assay result without its reporting basis, and receiving damp or caked powder. A generic certificate can conceal differences between batches. Agree acceptance criteria and independent sampling before dispatch, then hold discrepant material pending investigation.
A preparation containing para-toluenesulphonamide does not qualify for this suspension merely because it contains the named substance. If rejected stock is to be returned, confirm whether it is waste before arranging transport. Waste shipped from England under notification controls requires consent from the authorities of destination, dispatch and transit.

Frequently asked questions
What is the UK import duty on para-toluenesulphonamide from China?
The supplied tariff record shows 6% for 2935 90 90 20, suspended to 0% for qualifying goods. Mixtures and preparations are excluded from the suspension. No anti-dumping or countervailing duty is listed.
Does a para-toluenesulphonamide mixture qualify for zero duty?
Ask your customs broker to confirm the classification and applicable rate.
What should I test before accepting a batch?
Check identity, para-isomer content, other isomers, agreed impurities, water content and particle size. Match the analysis certificate to the delivered batch and compare results on the same reporting basis.
Do I need UK REACH registration?
For industrial-use imports into Great Britain, ask HSE to confirm applicable UK REACH registration requirements and any exemptions. Confirm the route and responsible party before ordering.
