Sourcing bitumen emulsions from China

Duty and waste controls

Read from the UK Trade Tariff on 29 September 2026, heading 2715 covers bituminous mixtures based on natural asphalt, natural bitumen, petroleum bitumen, mineral tar or mineral tar pitch. This guide focuses on bitumen emulsions. The supplied extract contains a single commodity line, so the table describes emulsion types sharing that code rather than separate tariff subdivisions.

Goods from China carry 0% duty under 2715 00 00 00, with no anti-dumping or countervailing duty and no suspension recorded. The tariff attaches import and export waste controls. If material from China is waste subject to notification controls, the exporter must apply to the Chinese competent authority for consent. Ask the relevant waste authority to confirm which destination, dispatch and transit consents are needed and when shipment may proceed. Confirm waste status and the applicable procedure with your customs broker and relevant waste authority before shipment.

Confirm the commodity code using the complete formulation and intended use. See the wider bituminous mixtures guide for other products within the heading. The import duty and VAT guide explains the tax calculation.

Specify emulsion type and breaking behaviour

Specify cationic or anionic emulsion, the base binder, any polymer modification and the intended application. Agree binder residue, viscosity, storage stability and breaking behaviour using named test methods and acceptance criteria. For a tack coat or aggregate treatment, approve an application trial on the actual surface or aggregate before ordering.

Ask for storage, agitation and handling instructions, including precautions against freezing and overheating. Obtain a safety data sheet matching the actual formulation. For sale in Great Britain, classification and labelling must be carried out by someone with scientific competence. Check the formulation's UK REACH position with your chemical adviser and agree labels and packaging before production. Use testing and certification support to plan specification checks.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of cationic bitumen emulsion in sealed drums under 2715 00 00 00, invoiced at £24,000 free on board, with £1,800 of freight and insurance to the UK. The customs value is £25,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £25,800, so it is £5,160. 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

Identity: match the emulsion type, formulation declaration, batch certificate and safety data sheet to the approved sample.

Condition: check for separated water, lumps, skin and sediment; compare viscosity and binder residue with the agreed specification.

Application: trial the emulsion on the intended substrate or aggregate and check spreading, breaking behaviour and adhesion after curing.

Packing: inspect drum seams, seals, leaks, corrosion and batch identification. Record discrepancies using the quality inspection guide.

What goes wrong

An emulsion can arrive separated or with coagulated lumps after unsuitable storage or handling. Extra water changes the binder delivered for a given application rate. A formulation that looks acceptable in a container may break too early or adhere poorly on the buyer's aggregate. Compare the delivered batch with a retained sample and the approved application trial.

Do not accept a generic bitumen certificate as evidence for the finished emulsion. Require batch results for the agreed emulsion properties and resolve discrepancies before use. Reclaimed ingredients also need their waste status checked before shipment; ask your broker to confirm the actual consignment's requirements.
