Sourcing methylprednisolone from China
Methylprednisolone active ingredient from China has a 0% UK duty rate where classified as other steroidal hormones under heading 2937. For human medicines, UK importers and distributors must register with MHRA; confirm applicable good manufacturing practice requirements with MHRA. Cambridge China Bridge sources methylprednisolone active ingredient.
Duty and controls for methylprednisolone
Read from the UK Trade Tariff on 7 October 2026, heading 2937 covers hormones and their derivatives and structural analogues. The relevant category to check for methylprednisolone is other steroidal hormones, their derivatives and structural analogues, under 2937 29 00 00. The table shows purchasing forms against this same broad line, rather than separate tariff subdivisions. Confirm the exact substance and presentation before declaring it.
The supplied tariff record gives 0% duty for goods from China on this line, with no recorded anti-dumping or countervailing duty and no listed suspension. All supplied lines within the heading carry 0%, so there is no duty variation within this record. Finished medicines in measured doses and bulk medicament mixtures have different classifications.
The tariff attaches Home Office controlled-drug import and export controls and an export waste control. A licence is required for imports or exports of controlled drugs or precursor chemicals. Ask your customs broker to confirm whether these entries apply to the exact material, including the waste entry before returning rejected stock. Confirm your commodity code, and see the prednisolone guide for wider heading context.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Methylprednisolone active ingredient | 2937 29 00 00 | 0% | None |
Specify the methylprednisolone form and batch
State whether you want methylprednisolone itself, the acetate or sodium succinate. Agree the pharmacopoeial monograph, assay basis, related substances, residual solvents, water content, particle size and any micronisation or crystal-form requirement. Match the specification to the receiving manufacturer's intended process. Specify sealed inner packing, storage conditions and a retest date.
For human-medicine use, UK importers and distributors must register with MHRA; confirm applicable good manufacturing practice requirements with MHRA. Arrange the exporting authority's written confirmation before shipment: MHRA guidance says to obtain it from the issuing authority in the exporting country. Request the actual manufacturing site's documents, batch certificate of analysis and regulatory-file materials. Use factory verification to check who makes the material.
Worked duty example
Illustrative example, not a quote: Illustrative order: 25 kg of methylprednisolone active ingredient 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: check that the ordered chemical form matches the container labels, invoice and batch certificate; independently test identity.
Batch quality: test assay, related substances, residual solvents and water against the agreed specification; assess particle size where specified.
Documents: match the batch number and manufacturing site across the certificate of analysis, manufacturing-practice evidence and written confirmation.
Packing: check intact seals, inner liners, contamination, storage instructions and retest information. Record arrival condition before sampling; see quality inspection explained.

What goes wrong
A quotation can leave the chemical form unclear, while an acceptable assay can hide an unsuitable impurity profile or particle size. A trader's certificate may also leave the actual manufacturing site unidentified. Resolve these gaps before approving the batch.
Do not accept a change of form, manufacturing site or specification solely because the supplier calls it equivalent. Have the receiving manufacturer's quality team assess the change, reconcile the documents and agree independent testing before accepting the material.
