Sourcing peppermint essential oil from China

Peppermint oil duty and classification

Heading 3301 covers essential oils and related extracts. Peppermint oil from Mentha piperita has separate lines for oil that is not deterpenated and oil that is deterpenated. The other mint rows are classification comparisons, not substitutes for peppermint. See the wider essential oils guide.

Read from the UK Trade Tariff on 30 October 2026, both peppermint lines carry 0% duty for goods from China. No anti-dumping duty, countervailing duty or suspension is recorded. The tariff attaches an organic import control and a mercury export control. Confirm the organic requirement for your intended use with your customs broker; also ask the broker to confirm the scope of the attached export measure.

For organic food-use oil from China entering Great Britain, arrange a certificate of inspection for each consignment and check the exporter’s control body and export country against the non-UK organic registers. Confirm the commodity code using botanical identity, processing and composition. Blended flavourings or fragrances may fall outside the single-oil heading.

Specify peppermint identity and intended use

Specify Mentha piperita, whether the oil is deterpenated, its intended application and whether any carrier oil or other ingredient is added. Agree a batch composition profile, including menthol and menthone, and acceptance ranges with your laboratory. Request a batch analysis certificate and retain the approved sample.

For Great Britain chemical supply, arrange competent classification and check labels and packaging before placing the oil on the market. Confirm with HSE whether a safety data sheet is required for supply to business customers. Review your UK REACH role and obligations for the intended use. If the product is sold as a finished cosmetic, confirm Responsible Person, safety assessment, product information file and notification requirements with the relevant cosmetics authority before sale.

Worked duty example

Illustrative example, not a quote: Illustrative order: 200 kg of peppermint essential oil, not deterpenated under 3301 24 10 00, invoiced at £6,000 free on board, with £600 of freight and insurance to the UK. The customs value is £6,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £6,600, so it is £1,320. 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 gas chromatography report with the agreed peppermint profile and retained sample. Check that the botanical identity and deterpenation status match the purchase order.

Consistency: check relative density, refractive index, optical rotation, colour and odour against agreed ranges. Investigate differences rather than accepting a scent match as proof of purity.

Documents: match batch identifiers across the analysis certificate, labels and English safety data sheet. Check the transport classification with the forwarder and obtain allergen composition for cosmetic users.

Packaging: inspect compatible drums or bottles, closures, tamper seals and signs of leakage. Check the agreed fill quantity and nitrogen headspace specification; retain an arrival sample.

What goes wrong

A quotation saying only mint oil leaves botanical identity unresolved. Other mint oil, a blend or oil diluted with a carrier can arrive against an order intended for peppermint. A familiar smell does not establish identity or purity. Require approval before any botanical, processing or composition change.

Warm storage, poorly sealed packs and part-filled drums can damage freshness. Reports may describe an earlier batch while the delivered oil has different composition. Hold affected stock while the supplier and laboratory reconcile the batch evidence; use testing and certification support to agree the checks before shipment.
