Sourcing acetone and ketone solvents from China

Mostly 4%

Read from the UK Trade Tariff on 26 September 2026, acetone, butanone, methyl isobutyl ketone, cyclohexanone and methylcyclohexanones, phenylacetone, diacetone alcohol, anthraquinone and other ketones and quinones of heading 2914 carried 4% duty on goods from China, and coenzyme Q10 0% as a pharmaceutical substance or 4% otherwise, with no anti-dumping measure. Many named specialty ketones have their own lines. A suspension gives 0% to cyclohexanone of 99% purity or more until 30 June 2027, and many named specialty ketones have their own 0% lines to 2028; none applies to mixtures. Re-checked on 27 September 2026 across all 72 leaves: 5-methylhexan-2-one (2914 19 10 00) and 1,4-naphthoquinone (2914 69 10 00) carry 0%, and other ketone-alcohols and ketone-aldehydes, including benzoin (2914 40 90 10 and 2914 40 90 90), carry 2%, or 0% for listed pharmaceutical products under additional code 2500.

Solvent blends and thinners are in heading 3814 and ketone-based preparations are classified by what they are; confirm the commodity code and CAS number. For chlorinated solvents, see our chlorinated solvents sourcing guide.

Precursor controls and hazards

Annex I to the retained drug precursors regulation lists 1-phenyl-2-propanone (phenylacetone) in category 1 and acetone and butanone in category 3. The tariff requires Home Office precursor authorisation for phenylacetone at import, and the Home Office guidance explains the domestic licensing and end-user declaration rules for each category, so check the quantities and uses before ordering acetone or MEK in bulk.

Acetone, MEK and MIBK are highly flammable liquids under GB CLP and dangerous goods for sea and air freight, so drums and IBCs need UN-approved packaging, labels and a safety data sheet, and importers above one tonne a year need a UK REACH registration position.

Worked duty example

An invented example rather than a quote: 20 tonnes of acetone in drums, commodity code 2914 11 00 00, bought for £18,000 free on board, with £3,500 of freight and insurance, so £21,500 is the value customs works from. Duty at the 4% rate for acetone is £860. VAT at 20% applies to £22,360, so £4,472. A VAT-registered buyer usually recovers the VAT, so the border adds £860 to the landed cost. See calculating UK import duty and VAT for the method.

Inspection checklist

Purity: assay and impurity profile by gas chromatography against the grade ordered, such as ASTM D329 for acetone or ASTM D740 for MEK, water by Karl Fischer titration, colour on the platinum-cobalt scale to ISO 6271, acidity and residue on evaporation, with the impurity profile also used to spot recovered solvent supplied against a virgin order.

Packaging and dangerous goods: drums or IBCs UN-marked for a packing group II flammable liquid, the UN number on each package matched to the product, such as UN 1090 for acetone, UN 1193 for MEK and UN 1245 for MIBK, closures and gaskets checked, ullage left for expansion, and seal numbers recorded against the container.

Documents and samples: a certificate of analysis per batch matched to drum numbers, a GB CLP safety data sheet in English, precursor paperwork for acetone, MEK and phenylacetone where it applies, and a retained sample from each batch drawn at loading and kept until the solvent is used.

What goes wrong

Solvents fail on purity, water and packaging. Water content above the specification spoils coatings and electronics cleaning, residues and colour exceed the grade, and recovered or recycled solvent can be supplied against an order for virgin material. Drums with poor closures leak or lose volume in hot containers, and paperwork that omits the UN number or packing group stops a booking.

Ask for a certificate of analysis per batch covering assay, water, residue on evaporation and colour, test the first delivery in a UK laboratory, specify virgin material in writing, check UN-marked drums, closures and labels before loading, and confirm the precursor paperwork for acetone and MEK where it applies.
