Sourcing budesonide active ingredient from China
Budesonide active ingredient from China has 0% UK duty under the candidate other-steroidal-hormones line. UK-based importers for human medicines must register with MHRA and meet manufacturing and distribution requirements. Confirm the written-confirmation route before shipping. Cambridge China Bridge sources budesonide active ingredient.
Budesonide duty and tariff controls
Read from the UK Trade Tariff on 7 October 2026, heading 2937 covers hormones and their derivatives and structural analogues, alongside prostaglandins, thromboxanes and leukotrienes. For separate budesonide active ingredient, start classification checks with 2937 29 00 00, other steroidal hormones and their derivatives and structural analogues. The table shows supply forms sharing this candidate line, rather than separate tariff classifications.
The supplied tariff record shows 0% duty for goods from China across this heading, including the candidate budesonide line. It records no anti-dumping or countervailing duty and no suspension. The budesonide candidate line carries Home Office controlled-drug import and export flags, plus a waste export flag. Confirm applicability with your customs broker. If the substance is controlled, commercial import or export requires a licence; the tariff flag alone does not settle its status.
Confirm the chemical identity, composition and supplied form using finding your commodity code. Do not classify finished inhalers, capsules or formulated suspensions solely from this active-ingredient guide. For the wider heading, see the dexamethasone active ingredient guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Budesonide active ingredient | 2937 29 00 00 | 0% | None |
Specify budesonide for the intended formulation
State whether the order is for separate budesonide powder and whether micronisation is needed. Agree the pharmacopoeial monograph, identity tests, assay, related substances, residual solvents, particle-size distribution and test methods. Ask the receiving manufacturer's quality team to approve the specification, including the epimer profile and any relevant solid-form checks, before accepting a sample.
UK-based active-substance importers must register with MHRA and comply with good manufacturing and distribution practice. Official guidance sets out an exporting-authority written-confirmation requirement for equivalent manufacturing practice and regulatory oversight, with an approved-country exception. Confirm the applicable documentation route with MHRA for the Chinese manufacturing site before shipment. Request the producer's manufacturing-quality evidence and documents needed by the receiving manufacturer; use factory verification to check the actual production site.
Worked duty example
Illustrative example, not a quote: 25 kg of budesonide active ingredient; illustrative order and values under 2937 29 00 00, invoiced at £40,000 free on board, with £800 of freight and insurance to the UK. The customs value is £40,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £40,800, so it is £8,160. 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 container labels, batch certificate of analysis and shipping documents to the agreed budesonide material and manufacturing site.
Laboratory: arrange independent identity, assay, related-substance and residual-solvent checks against the agreed specification; include the agreed epimer-profile assessment.
Particle size: check the delivered batch against the approved distribution and test method, rather than accepting a supplier's description of 'micronised'.
Packing: inspect seals, liners, batch traceability, retest information and evidence of the agreed storage conditions. Plan sampling through the receiving quality team; see quality inspection explained.

What goes wrong
A batch can match the agreed assay yet fail the impurity or particle-size specification. A sample approved from one site may also be followed by production from another. Compare the delivered batch with the approved sample and documents, and hold material with unexplained differences for the receiving manufacturer's assessment.
A certificate of analysis does not establish the importer's registration or resolve written-confirmation documentation. Settle those checks before dispatch, alongside the tariff control query. Agree how failed batches will be investigated and handled before ordering; ask your broker about the tariff's waste export flag before arranging any return.

Frequently asked questions
What is the UK import duty on budesonide from China?
The supplied tariff record shows 0% on 2937 29 00 00, the candidate line for separate budesonide active ingredient, with no anti-dumping or countervailing duty. Confirm classification for the supplied material.
Do I need MHRA registration to import budesonide active ingredient?
Yes, if you are a UK-based importer of active substances for human medicines. MHRA guidance also requires compliance with good manufacturing and distribution practice.
What documentation should I check before shipping from China?
Check importer registration, the actual manufacturing site, manufacturing-quality evidence and batch analysis. Confirm with MHRA the exporting-authority written-confirmation route applicable to that site.
Is micronised budesonide interchangeable with ordinary powder?
Do not assume interchangeability. Have the receiving manufacturer approve the particle-size distribution, test method and intended formulation use, then check the delivered batch against that specification.
