Sourcing sodium peroxide from China

Sodium peroxide duty and waste controls

Read from the UK Trade Tariff on 6 November 2026, sodium peroxide falls within 2815 30 00 00, covering peroxides of sodium or potassium. Goods from China carry 4% duty. The supplied tariff facts list no anti-dumping or countervailing duty and no suspension.

The tariff attaches import and export waste controls. Waste shipment controls apply only where the material is waste. For sodium peroxide waste from China, the importer should confirm the applicable requirement with their customs broker before shipment. Do the same before any return shipment classed as waste.

Only the peroxide commodity line is relevant to this guide. Confirm the product identity and commodity code. See the caustic soda and caustic potash guide for the wider heading.

Specify peroxide assay and the intended use

Specify sodium peroxide explicitly, rather than accepting a quotation for an unspecified peroxide. Agree the peroxide assay, permitted impurities, physical form and test methods. For laboratory use, ask the buyer's laboratory to define acceptance criteria for the intended analytical procedure.

Request a certificate of analysis for each batch and an English safety data sheet. Confirm with HSE which UK REACH registration or only-representative arrangements apply to your imports. Everyone in the chemical supply chain must ensure correct labelling and packaging before placing substances on the Great Britain market.

Agree container material, closure, seal and handling instructions against the product's safety data sheet. Arrange laboratory sampling before dispatch rather than improvising sampling when the consignment arrives.

Worked duty example

Illustrative example, not a quote: Illustrative laboratory supply order in sealed containers, not a quotation under 2815 30 00 00, invoiced at £16,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £19,000. Duty at 4% is £760. Import VAT at 20% is charged on the customs value plus duty, £19,760, so it is £3,952. Import taxes total £4,712; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £760 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match sodium peroxide on the purchase order, invoice, safety data sheet and batch certificate.

Assay: compare batch results with the agreed peroxide assay and impurity limits; check that the laboratory used the agreed methods.

Containers: check seals, closures and external condition against the approved packing specification; record leakage, damage or visible deposits.

Traceability: match container batch references to certificates and keep arrival photographs. Plan checks through our quality inspection guide.

What goes wrong

An assay certificate without a test method leaves the buyer unable to compare results. An unspecified peroxide quotation can also conceal a product-identity mismatch. Make the chemical name, acceptance criteria and batch-document requirements part of the purchase order.

Damaged closures, missing batch references and inconsistent paperwork undermine acceptance on arrival. Separate affected stock pending assessment, record the defects and ask the supplier for a documented resolution. Avoid informal repacking or testing without an agreed handling procedure.
