Sourcing Manganese Monoxide from China
Manganese monoxide from China carries 0% UK duty on both relevant tariff lines, with no listed anti-dumping or countervailing duty. Buyers should confirm their UK REACH registration position with HSE and ensure correct chemical labelling and packaging before supply in Great Britain. Cambridge China Bridge sources manganese monoxide.
Manganese monoxide duty and classification
Read from the UK Trade Tariff on 29 September 2026, heading 2820 covers manganese oxides. For manganese monoxide, the relevant lines are 2820 90 10 00 for manganese oxide containing at least 77% manganese by weight, and 2820 90 90 00 for other material. Both carry 0% duty from China, with no listed anti-dumping or countervailing measure and no suspension. Only these tariff lines are relevant to this guide.
The tariff attaches import and export waste controls to both lines. For waste imported into England under notification controls, the Chinese exporter must apply to the competent authority in the country of dispatch for consent. Ask your customs broker to confirm the product's waste status and applicable import requirements before shipment; also confirm the attached export control if planning a return shipment.
Give your broker the composition, manganese assay, oxide identity and intended use to confirm the commodity code. Keep elemental manganese content separate from manganese monoxide purity on the certificate. For another oxide within the wider heading, see manganese tetroxide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Manganese monoxide containing at least 77% manganese by weight | 2820 90 10 00 | 0% | None |
| Other manganese monoxide, subject to composition and classification | 2820 90 90 00 | 0% | None |
Specify oxide identity and manganese assay
Name manganese monoxide explicitly in the purchase specification. Agree separate results for elemental manganese content and manganese monoxide assay, with the reporting basis and test methods. Specify particle size distribution, moisture, insoluble material and limits for iron, lead and other impurities relevant to your process. Ask the laboratory how it will distinguish monoxide from other manganese oxides.
Request a batch certificate, safety data sheet and a retained sample. Confirm with HSE how annual import quantities affect your UK REACH registration obligations; registration is per substance and per legal entity. Chemical supply in Great Britain requires correct labelling and packaging. A safety data sheet is required when a hazardous chemical is supplied for workplace use. Agree lined packaging and trial the sample in your intended process.
Worked duty example
Illustrative example, not a quote: Illustrative order: one tonne of manganese monoxide in lined bags under 2820 90 10 00, invoiced at £3,400 free on board, with £980 of freight and insurance to the UK. The customs value is £4,380. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,380, so it is £876. 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: check the laboratory result confirms manganese monoxide and investigate other oxide phases rather than accepting a total manganese result alone.
Assay: compare manganese content, monoxide assay, moisture and agreed impurities with the batch certificate; send representative samples for independent testing.
Powder and packing: check particle size against the agreed method, look for caking and contamination, and inspect liners, closures and net weight.
Documents: match bag labels, batch marks, certificate and safety data sheet to the delivered lot. Include these checks in the inspection brief.

What goes wrong
A manganese assay can be mistaken for a monoxide purity result, or the supplier can provide another manganese oxide under a shortened product name. These errors leave the buyer without evidence that the powder matches the ordered compound. Moisture, coarse particles or contamination can also make an otherwise acceptable assay unsuitable for the buyer's process.
Agree identity testing and acceptance criteria before placing the order. Keep a sealed reference sample, compare the shipment with the approved trial material and investigate discrepancies before using or selling the batch.

Frequently asked questions
What is the UK import duty on manganese monoxide from China?
Both relevant lines, 2820 90 10 00 and 2820 90 90 00, carry 0% duty in the supplied tariff facts, with no listed anti-dumping or countervailing duty.
Which commodity code should I use for manganese monoxide?
2820 90 10 00 describes manganese oxide containing at least 77% manganese by weight. The other relevant line is 2820 90 90 00. Have your broker confirm classification from the composition and assay.
Does manganese monoxide need UK REACH registration?
Confirm with HSE how annual import quantities affect your UK REACH registration obligations. Check your arrangements before importing; registration is per substance and per legal entity.
What should I test before accepting manganese monoxide?
Check oxide identity, elemental manganese content, monoxide assay, moisture, particle size and agreed impurities. A total manganese result alone does not establish the oxide identity.
