Sourcing natural indigo dye from China
Natural indigo dye of vegetable origin from China carries 0% UK duty, with no anti-dumping or countervailing duty shown. For textile use in Great Britain, check your UK REACH registration position before importing. Confirm plant origin and test each batch in your dyeing process. Cambridge China Bridge sources natural indigo dye.
0% duty on natural indigo dye
Read from the UK Trade Tariff on 4 October 2026, natural indigo of vegetable origin falls within 3203 00 10 00, covering vegetable colouring matter and preparations based on it. The recorded duty for goods from China is 0%, with no anti-dumping or countervailing duty and no suspension listed. The wider heading includes dyeing extracts but excludes animal black.
The vegetable-origin line carries veterinary, CITES and waste import controls, plus CITES and waste export controls. For natural indigo, ask your customs broker to confirm the veterinary requirement against the full formulation before shipment. Do not assume that an animal-origin ingredient can be treated as vegetable dye. Confirm the export controls separately before any onward export.
Confirm plant origin, processing and all added ingredients when checking the commodity code. Only the vegetable-origin line in the supplied tariff facts is relevant to this guide. See the wider natural colours and dyes guide for other products, and import duty and VAT for the calculation method.

Specify plant origin and dyeing performance
Specify the source plant, extraction process, powder or paste form, declared indigo content, colour strength and every carrier or additive. Ask for production records supporting the natural-origin claim. Agree a reference sample and test the dye on your actual yarn or fabric using the intended vat preparation, reduction, dyeing and washing process. Specify acceptable shade, rubbing transfer and wash performance in the purchase agreement.
For textile or craft use in Great Britain, check whether the substance requires UK REACH registration before importing. Ask for substance identity, composition and safety information, and review your UK REACH position. A supplier's description of the product as natural is not enough information to settle that assessment.
Check the source species against the CITES control. If the extract is a CITES specimen, permits are required for movement into or out of Great Britain, and the corresponding Chinese authority must also be contacted. If material is waste subject to notification controls, the Chinese exporter must apply to the competent authority in the country of dispatch for consent. Confirm the applicable route with your customs broker.
Worked duty example
Illustrative example, not a quote: 2 tonnes of natural indigo powder for textile dyeing, illustrative only under 3203 00 10 00, invoiced at £24,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £25,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £25,500, so it is £5,100. 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 the batch composition and source-plant records with the agreed specification. Ask a laboratory to investigate suspected synthetic dye additions or undeclared carriers.
Strength and shade: compare colouring power with the approved reference and run a dyeing trial on the intended textile. Check the washed and dried fabric, including colour transfer during rubbing.
Condition: check sampled packs for moisture, hard lumps, contamination and damaged seals. Confirm that powder or paste behaves consistently during preparation of the dye bath.
Batch records: match pack labels, certificates of analysis and retained samples to the delivered lot. Record arrival findings and use the quality inspection guide to agree release checks.

What goes wrong
A blue powder and a matching certificate do not establish natural origin or dyeing performance. Undeclared synthetic dye or carriers can undermine the specification. Low colour strength, inconsistent shade and caking can make the delivered batch behave differently from the approved sample.
Keep an approved reference and an arrival sample from each lot. Investigate differences using the same textile and dyeing process before changing the recipe or accepting replacement stock. Make batch acceptance depend on the agreed tests rather than the supplier's colour description.

Frequently asked questions
What is the UK import duty on natural indigo dye from China?
The supplied tariff record shows 0% duty under 3203 00 10 00 for vegetable-origin colouring matter, with no anti-dumping or countervailing duty listed. Confirm the formulation and code before shipping.
Does synthetic indigo use the same commodity code?
This guide covers vegetable-origin natural indigo. Synthetic dyes belong in the separate textile dyes category. Give your customs broker the origin, processing details and complete formulation.
Does natural indigo need UK REACH registration?
Check whether the identified substance requires registration before importing into Great Britain. Review its composition, processing and annual quantity; do not rely solely on the word natural.
How should I compare natural indigo samples?
Compare colour strength and dye the same yarn or fabric using the same process. Assess shade after washing and drying, rubbing transfer and batch consistency against an approved reference.
