Sourcing natural brucite from China

Natural brucite duty and classification

Read from the UK Trade Tariff on 1 October 2026, heading 2530 covers mineral substances not elsewhere specified or included. For natural brucite, confirm whether the residual line 2530 90 70 90 fits the actual material. The purchasing forms in the table share that proposed line; they are not separate tariff subdivisions.

The supplied tariff record gives 0% duty for goods from China under this line, with no anti-dumping or countervailing measure and no suspension recorded. It attaches import and export waste controls. Ask your customs broker to confirm their application to the shipment. For a shipment from China to England subject to waste notification controls, obtain consent from the Environment Agency and the other competent authorities before shipping.

Give your broker the mineral analysis, processing description and details of any coating or additives to confirm the commodity code. Keep this guide's scope to uncoated natural brucite. For the wider heading, see the natural hydromagnesite powder guide.

Specify mineral identity and powder behaviour

Specify natural mined brucite and disclose the mine, processor and processing route. Agree magnesium hydroxide content, mineral impurities, moisture, particle size distribution and coarse residue. Record whether the assay is reported on a dry basis. For powder used in a compound, approve dispersion and processing behaviour in your own formulation rather than accepting a flame-retardant claim alone.

Importers are among the chemical suppliers responsible for classification. Obtain composition and hazard information for the actual grade, including impurities and additives. Check whether that substance requires UK REACH registration. Ask for the supplier's supporting documents rather than treating the word 'natural' as a complete compliance answer. Agree independent analysis through testing and certification.

Worked duty example

Illustrative example, not a quote: Illustrative order: 10 tonnes of uncoated natural brucite powder in lined bulk bags under 2530 90 70 90, invoiced at £9,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £10,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £10,200, so it is £2,040. 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: compare mineral identification and assay results with the approved sample, and match the analysis certificate to the delivered batch.

Grading: check particle size distribution and coarse residue using the agreed method; examine powder for hard agglomerates and foreign particles.

Condition: test moisture and inspect for dampness, caking, colour variation and contamination before releasing the material into production.

Packing: check bag seams, liners, batch identification and declared weight against the packing list; retain labelled samples from the received batch.

What goes wrong

A magnesium assay alone can conceal a different mineral mix. Excess carbonate, silica or iron-bearing impurities can change colour and processing behaviour. A fine laboratory sample may also conceal coarse particles or agglomerates in the shipment. Agree mineral identification, impurity reporting and sampling before ordering.

Wet powder cakes during transport, damaged liners admit contamination, and a substituted coated grade may behave differently from the approved uncoated sample. Hold discrepant bags separately and compare retained samples, batch reports and your process trial before accepting a replacement or repeat order.
