Sourcing sulphuryl chloride from China

Sulphuryl chloride duty and classification

Read from the UK Trade Tariff on 29 September 2026, heading 2812 covers halides and halide oxides of non-metals. Sulphuryl chloride is not named separately in the supplied tariff lines. The candidate residual chloride and chloride oxide line, 2812 19 90 00, carries 4% duty for goods from China, with no listed anti-dumping or countervailing measure and no suspension.

The UK Trade Tariff attaches import and export waste controls to this line. For material declared as waste, confirm the requirements for a shipment from China with your customs broker. Under notification controls, the exporter must apply for consent to the competent authority in the country of dispatch. Confirm the applicable route before buying recovered or discarded material.

Confirm the chemical identity, composition and commodity code before shipment. The comparison rows are different sulphur chlorides, not additional sulphuryl chloride grades. For the wider heading, see thionyl chloride and related tariff lines.

Specify sulphuryl chloride identity and assay

Write sulphuryl chloride explicitly on the order. Ask the factory to confirm the chemical identity on the specification, batch certificate and safety data sheet. Agree assay, acidity, free chlorine, colour and impurity limits with your laboratory, together with suitable test methods. Specify the container material, closure and net contents rather than accepting a generic industrial-grade description.

For Great Britain, establish the UK REACH registration position when annual imports reach one tonne or more. Chemical supply also needs the applicable classification, labelling and packaging arrangements. Safety data sheets are required for hazardous chemicals supplied for workplace use. Obtain the sheet before agreeing storage, sampling or unloading.

Worked duty example

Illustrative example, not a quote: Illustrative pilot order of 25 kg of sulphuryl chloride; values are illustrative under 2812 19 90 00, invoiced at £2,000 free on board, with £980 of freight and insurance to the UK. The customs value is £2,980. Duty at 4% is £119.20. Import VAT at 20% is charged on the customs value plus duty, £3,099.20, so it is £619.84. Import taxes total £739.04; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £119.20 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the product name and chemical identity across the order, container labels, safety data sheet and batch certificate; distinguish sulphuryl chloride from thionyl chloride.

Batch quality: check assay, acidity, free chlorine and the agreed impurities against the batch certificate. Arrange laboratory sampling and independent analysis using an agreed procedure.

Containers: check seals, closures, container condition, net contents and batch markings. Record damage or leakage before accepting the delivery.

Documents: check hazard labels and packaging against the applicable supply requirements, and confirm that the safety data sheet describes the delivered product. Include these checks in the inspection plan.

What goes wrong

A similar product name can hide a different chemical. A sulphuryl chloride order may be confused with thionyl chloride, while a generic certificate may omit acidity, free chlorine or the impurities relevant to your process. Match identity before comparing quotations and agree acceptance tests before production.

Other rejection points include leaking closures, damaged containers, missing batch identification and certificates that cannot be matched to the shipment. Photograph containers on arrival, keep affected stock separate and refer sampling or opening to the receiving laboratory's agreed handling procedure.
