Sourcing N-ethyl tosylamide from China
N-ethyl-para-toluenesulphonamide from China has a 6% base UK duty, with a 0% suspension for qualifying goods. Check substance identity and the UK REACH route before importing into Great Britain; mixtures do not inherit the suspension. Cambridge China Bridge sources N-ethyl-para-toluenesulphonamide.

Base duty and the toluenesulphonamide suspension
Read from the UK Trade Tariff on 5 October 2026, heading 2935 covers sulphonamides. The relevant supplied line is 2935 90 90 20, toluenesulphonamides, showing 6% duty for goods from China and an autonomous suspension to 0%. No anti-dumping or countervailing measure is recorded. The supplied suspension footnote excludes mixtures, preparations and products made up of different components containing these substances.
The supplied record attaches dangerous-chemical export and waste-export controls. Ask your customs broker to confirm their relevance to your shipment from China. HSE states that there are no prior informed consent notification obligations for imports. Waste shipment controls apply only where the material is waste; confirm the applicable route before ordering recovered or discarded material.
Only the relevant supplied tariff line is shown here. Confirm the commodity code using the full chemical identity and composition, and ask the broker to check suspension eligibility. The illustrative order values do not assume that relief is available. For related buying considerations, see the para-toluenesulphonamide guide.

Specify the N-ethyl compound and its impurity profile
Write N-ethyl-para-toluenesulphonamide in full, also known as N-ethyl tosylamide. Ask the supplier to confirm the chemical identity and whether the quotation covers a single substance or a formulated blend. Specify assay and its test method, permitted related substances, water content, residual solvents, appearance and packaging. Set acceptance criteria against an approved sample rather than a generic toluenesulphonamide description.
For ordinary industrial uses, confirm with HSE whether UK REACH registration is required for your planned imports and whether an exemption applies. Confirm the registration route before committing to supply. Classification and labelling must be carried out by someone scientifically competent. Obtain the safety data sheet and agree storage, handling and sampling arrangements alongside the batch specification.
Worked duty example
Illustrative example, not a quote: Illustrative trial order of N-ethyl-para-toluenesulphonamide in sealed drums under 2935 90 90 20, invoiced at £2,500 free on board, with £980 of freight and insurance to the UK. The customs value is £3,480. Duty at 6% is £208.80. Import VAT at 20% is charged on the customs value plus duty, £3,688.80, so it is £737.76. Import taxes total £946.56; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £208.80 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the purchase specification, drum labels, safety data sheet and batch certificate of analysis to the N-ethyl compound.
Analysis: independently check assay, related substances, water and residual solvents against the agreed methods and acceptance criteria.
Packing: check seals, leakage, contamination and readable batch labels; compare appearance with the approved sample.
Documents: check batch traceability, the UK REACH route and the broker's suspension assessment. Check the applicable chemical labels and packaging before sale in Great Britain.

What goes wrong
A quotation saying only toluenesulphonamide leaves room for the wrong compound or an undeclared blend. An acceptable headline assay can conceal an unsuitable impurity profile. Missing batch links make it difficult to establish whether the tested sample represents the delivered drums.
Treat identity, composition and suspension eligibility as separate checks. Quarantine material with mismatched documents or damaged seals until investigated, and trial the accepted batch in your process before wider use. Agree independent sampling through the testing and certification service.

Frequently asked questions
What is the UK import duty on N-ethyl-para-toluenesulphonamide from China?
The supplied toluenesulphonamide line shows 6% base duty and a 0% suspension for qualifying goods. Its footnote excludes mixtures and preparations. Confirm the identity and relief with your broker.
Is N-ethyl tosylamide the same product?
It is another name for N-ethyl-para-toluenesulphonamide. Ask the supplier to confirm chemical identity, composition and the batch specification rather than accepting the abbreviated name alone.
Do I need UK REACH registration?
Confirm your supply chain's registration route before importing.
What should I test before accepting the drums?
Check identity, assay, related substances, water and residual solvents against the agreed specification. Match the laboratory sample and certificate to the delivered batch, then trial it in your process.
