Sourcing BF3 acetonitrile complex from China

0% duty, subject to confirming classification

Read from the UK Trade Tariff on 15 October 2026, heading 2942 covers other organic compounds. Its residual line, 2942 00 00 90, carries 0% duty for goods from China. The supplied tariff data records no anti-dumping or countervailing duty and no suspension. It does not name boron trifluoride acetonitrile complex separately.

The UK Trade Tariff attaches Veterinary control and Export control - Waste to this line. Their application to this reagent has not been established; ask your customs broker to confirm the requirements before shipment from China. For material subject to waste notification controls, the exporter must apply to the competent authority in the country of dispatch for consent.

Confirm the commodity code using the chemical identity, composition and whether the goods are a complex or a formulated solution. Only the residual line is relevant to this focused table. For related sourcing considerations, see the boron trifluoride diethyl etherate guide.

Specify the acetonitrile complex precisely

State the chemical identity, complex composition, assay basis, boron trifluoride content, free acetonitrile, water content and agreed impurity limits. Distinguish the complex from a solution and from complexes with other solvents. Agree the analytical methods, container material, closure, storage conditions and batch certificate of analysis before ordering.

For Great Britain, confirm with the relevant authority whether UK REACH registration or only representative coverage is needed for your planned annual imports. Correct chemical labelling and packaging are required before placing goods on the market. Obtain the English safety data sheet and check it against the actual composition supplied.

Worked duty example

Illustrative example, not a quote: 20 kg in sealed laboratory bottles, illustrative only under 2942 00 00 90, invoiced at £2,500 free on board, with £980 of freight and insurance to the UK. The customs value is £3,480. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,480, so it is £696. 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 purchase specification, bottle labels, safety data sheet and batch certificate to the acetonitrile complex.

Analysis: have a competent laboratory check the agreed assay, boron trifluoride content, free solvent and moisture using the agreed methods.

Containers: inspect closures, seals and outer packaging for leakage, damage and evidence of previous opening; compare the packing with the agreed specification.

Traceability: reconcile batch marks and quantities with the packing list, and keep the batch results with the goods. Plan sampling through the laboratory rather than opening containers during a general warehouse inspection.

What goes wrong

A quotation for an unspecified boron trifluoride complex can conceal a different solvent complex or a solution with a different concentration. An assay figure is difficult to compare when suppliers use different reporting bases. Require the composition and test method in writing, then compare a trial batch with your process specification.

Treat mismatched batch documents, leaking closures or results outside the agreed moisture limit as reasons to hold the goods pending investigation. Agree acceptance and rejection criteria before dispatch. Use the inspection guide to organise the document and sampling checks.
