Sourcing manganese oxides from China

Duty and waste controls

Read from the UK Trade Tariff on 18 November 2026, heading 2820 covers manganese oxides. It separates electrolytic manganese dioxide not heat treated after electrolysis, other manganese dioxide, manganese oxide containing at least 77% manganese by weight, and other manganese oxides.

Every listed line carries 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty and no suspension. It attaches import and export waste controls to every line. For material supplied as waste from China, ask your customs broker to confirm the applicable import procedure. For notified waste entering England, shipment must await consent from the Environment Agency and the other competent authorities involved.

Confirm the commodity code using the compound, manganese content, production method and subsequent heat treatment. Obtain the manufacturer's process declaration rather than classifying from a sales description alone.

Specify the oxide and its intended use

Name the manganese oxide and intended application, such as battery manufacture, ceramics or laboratory use. Specify oxide assay and total manganese separately, the measurement basis, moisture, particle size distribution, bulk density and impurity limits. For battery material, agree an application trial alongside chemical analysis. For electrolytic dioxide, record whether it undergoes heat treatment after electrolysis.

For imports into Great Britain, confirm with HSE or a competent chemical adviser whether UK REACH registration coverage is required for your substance, annual volume and supply arrangement. Before sale, ensure correct chemical labelling and packaging. Request a safety data sheet and batch analysis certificate, and agree the sampling and test methods in the purchase specification.

Worked duty example

Illustrative example, not a quote: Illustrative order: 25 tonnes of industrial manganese dioxide in lined bags under 2820 10 00 90, invoiced at £15,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £17,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £17,000, so it is £3,400. 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 oxide, production route and heat-treatment declaration to the order and batch certificate.

Composition: independently check oxide assay, total manganese, moisture and agreed impurities against the specification.

Powder: check particle size, agglomeration and bulk density; compare an application sample with the approved material.

Packing: check seals, liners, net weight, batch identification and labels against the safety data sheet. Arrange quality inspection before loading.

What goes wrong

A manganese assay alone does not establish the oxide grade or suitability for a battery process. Problems to check for include substitution of the production route, undeclared heat treatment, moisture uptake, coarse agglomerates and impurity results that differ from the certificate. Compare representative batch samples with the agreed specification and retain a sealed reference sample.

Reclaimed material described simply as manganese oxide can leave its waste status unresolved. Establish its origin and processing history before ordering, then ask your broker to confirm the tariff waste control. For deliveries outside England, confirm the applicable waste procedure with the receiving jurisdiction's authority.
