Sourcing coloured smoke canisters from China

Duty and classification for smoke canisters

Read from the UK Trade Tariff on 5 October 2026, heading 3604 covers fireworks, signalling flares, rain rockets, fog signals and other pyrotechnic articles. For coloured smoke canisters, start by checking the other-pyrotechnic-articles line, 3604 90 00 00. The table shows buying formats against this candidate line, rather than separate tariff subdivisions. Confirm the commodity code using the composition, ignition mechanism and intended use.

Both heading lines carry 0% duty for goods from China. The supplied tariff extract shows no anti-dumping or countervailing duty and no suspension. Import VAT is separate; see UK import duty and VAT. For the wider heading, see stage pyrotechnic fountains.

The tariff attaches import and export waste controls. If a shipment from China is waste subject to notification, it cannot move until the competent authorities of dispatch, transit and destination have consented. Ask your customs broker to confirm whether the controls apply to the consignment, particularly damaged stock or returns.

Specify the smoke effect and ignition mechanism

Specify the smoke colour, intended setting, ignition mechanism, canister construction, smoke duration and output, storage conditions and pack assortment. Agree how colour and performance will be compared with the approved sample. Assess each colour formulation separately rather than assuming a report for one colour covers every variant.

Confirm the conformity-assessment and CE or UKCA marking requirements for these pyrotechnic articles with the relevant product safety authority. Government guidance identifies smoke bombs as P1 products and prohibits selling them to anyone under 18. If the actual article is categorised P2, it can only be supplied to people with specialist knowledge. Obtain the category and supporting documents before agreeing the sales channel.

Explosives must be classified before carriage in Great Britain. Match the transport classification to the actual product before booking freight. Confirm the carrier's acceptance and the receiving warehouse's storage arrangements before production.

Worked duty example

Illustrative example, not a quote: 2,000 coloured smoke canisters; illustrative order, not a quotation under 3604 90 00 00, invoiced at £18,000 free on board, with £6,000 of freight and insurance to the UK. The customs value is £24,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £24,000, so it is £4,800. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.

Inspection checklist

Construction: check canisters for corrosion, dents, loose closures, exposed composition and damaged ignition parts. Keep suspect articles separate for specialist assessment.

Smoke performance: arrange controlled sample testing by a competent specialist against the approved colour, duration, output and ignition behaviour. Record the tested colour and batch.

Labels and documents: compare category, registration number, safety distance, English instructions and CE or UKCA marking with the approved documents. Match the product identity to its transport classification.

Packing and arrival: check moisture damage, internal movement, colour assortment and carton identification. Reconcile received batches with shipment records; see quality inspection explained.

What goes wrong

Problems to investigate include weak or inconsistent colour, interrupted smoke output, ignition failures, damaged pull mechanisms and corrosion after damp storage. Treat smoke duration, staining and canister heat as matters to assess in the intended setting. Do not accept unsupported claims that the product is harmless or suitable for every venue.

A different colour formulation or ignition assembly may leave the paperwork describing a different product. Compare production goods with the approved specification and resolve discrepancies before shipment. Arrange testing and certification around the actual smoke canister and its intended use.
