Sourcing Sulphur Dioxide from China
Sulphur dioxide from China carries a single UK duty rate of 4%, with no recorded anti-dumping duty or suspension. For Great Britain, check UK REACH coverage, chemical labels and approved transportable pressure equipment before ordering. Cambridge China Bridge sources sulphur dioxide.

Sulphur dioxide duty and attached controls
Read from the UK Trade Tariff on 1 October 2026, sulphur dioxide under 2811 29 05 00 carried 4% duty for goods from China. The supplied record shows no anti-dumping or countervailing measure and no tariff suspension. Heading 2811 covers other inorganic acids and other inorganic oxygen compounds of non-metals. The purchasing descriptions in the table share the same sulphur dioxide line.
The UK Trade Tariff attaches import and export waste controls. For a consignment from China treated as waste, confirm the applicable requirements with your customs broker before shipment. For imports into England under notification controls, shipment can start only after consent from the Environment Agency and the other competent authorities involved. Confirm the export waste control separately before arranging any return shipment.
Confirm the composition and presentation using our commodity code guide, especially for mixtures or solutions. For the wider heading, see sulphamic acid sourcing. Keep the gas specification separate from cylinder ownership and return terms.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Sulphur dioxide for industrial use | 2811 29 05 00 | 4% | None |
Specify sulphur dioxide purity and delivery equipment
State the intended process, required purity, moisture limit and named impurities in the purchase specification. Ask for a batch certificate of analysis showing actual results and test methods. Specify whether the supply is liquefied, the cylinder valve outlet, compatible regulator, net contents and cylinder return arrangements.
For Great Britain, establish the UK REACH position before ordering. Confirm with HSE which registration requirements, exemptions or manufacturer's UK only-representative arrangements apply to your imports. Hazardous chemicals supplied for workplace use need a safety data sheet. Obtain the English sheet and check the applicable classification, labelling and packaging requirements.
Confirm the dangerous goods classification and applicable cylinder conformity and approval requirements for use in Great Britain with the relevant transport authority or your customs broker. Ask for conformity markings, periodic inspection records and dangerous goods documents before dispatch.
Worked duty example
Illustrative example, not a quote: Illustrative order: 25 cylinders of industrial sulphur dioxide; cylinder ownership agreed separately under 2811 29 05 00, invoiced at £4,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £6,000. Duty at 4% is £240. Import VAT at 20% is charged on the customs value plus duty, £6,240, so it is £1,248. Import taxes total £1,488; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £240 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Batch identity: match cylinder labels, filling records and certificates of analysis to the purchased sulphur dioxide grade.
Purity: compare actual purity, moisture and specified impurity results with the contract, and agree independent testing where needed.
Cylinders and valves: check approval markings, inspection dates, valve outlets, protective caps and visible damage without opening valves during a visual inspection.
Arrival records: reconcile cylinder identifiers and declared net contents with the packing list, and record damage before acceptance. Set the scope through our inspection guide.

What goes wrong
A supplier's grade name can hide a different moisture or impurity specification. A certificate may describe a production batch without identifying the delivered cylinder batch. Put the acceptance limits and traceability requirements in writing, then compare the arrival records with the approved documents.
A valve outlet that does not fit the buyer's equipment, damaged valve protection or missing cylinder approval records can prevent use. Resolve equipment compatibility and cylinder ownership before shipment. Have the receiving site agree handling and leak-response arrangements using the safety data sheet.

Does sulphur dioxide need UK REACH registration?
For Great Britain, confirm the applicable UK REACH registration requirements and any exemption or manufacturer's UK only-representative coverage with HSE before ordering.
Can I use the supplier's cylinders in Great Britain?
Confirm the applicable transportable pressure equipment requirements with the relevant transport authority or your customs broker. Check approval markings, periodic inspection records and valve compatibility before accepting the supplier's proposed cylinders.
What should a sulphur dioxide certificate of analysis show?
The delivered batch identity, actual purity, moisture and named impurity results, plus test methods. Compare these with your written specification rather than relying on the grade name.
