Sourcing rice protein isolate from China
Unformulated rice protein isolate from China carries 2% UK duty, with no rice-specific suspension or listed trade remedy. Food-grade powder must be safe to eat; confirm any China-specific rice controls before shipment. Cambridge China Bridge sources unformulated rice protein isolate.
Rice isolate carries 2% duty
Read from the UK Trade Tariff on 1 October 2026, heading 3504 covers protein substances and their derivatives not elsewhere specified or included, alongside peptones and hide powder. For unformulated rice protein isolate, use 3504 00 90 99 as the candidate code. The table shows purchasing variants within this shared line, rather than separate tariff subdivisions.
The supplied tariff data records 2% duty for goods from China, with no listed anti-dumping or countervailing duty. The suspension on this line covers zein, not rice protein. The line also attaches veterinary control and organic import control. Ask port health and your customs broker to confirm whether veterinary checks or a declaration are required for the exact product. For organic rice isolate imported into Great Britain, confirm the certificate of inspection requirement with the relevant organic control body; the certificate is issued by the exporter’s control body.
Send the broker the full composition, manufacturing process and intended use to confirm the commodity code. Check added flavours, sweeteners or other ingredients separately. Before shipment, ask port health to confirm whether China-specific rice controls apply to the exact product. Our pea protein and protein isolates guide covers the wider heading.

Specify rice origin, assay and powder behaviour
Specify unformulated rice isolate, the rice source and the extraction process. Request a complete ingredient and processing-aid statement. Agree protein content on a dry basis, the analytical method and nitrogen conversion factor, together with moisture, ash, particle size, colour and odour. Test the sample in your actual drink, bar or bakery recipe for grittiness, sedimentation and flavour.
Food intended for human consumption must meet general food safety requirements, and importers must ensure it is safe and legal before import. Agree lot testing for arsenic, lead, cadmium, pesticide residues and microbiological quality. Genetically modified rice and rice products are not authorised in the UK. Ask the laboratory and port health which rice-specific screening is appropriate; arrange testing and certification against the agreed specification.
Worked duty example
Illustrative example, not a quote: Illustrative order: 2000 kg of unformulated rice protein isolate under 3504 00 90 99, invoiced at £16,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £17,500. Duty at 2% is £350. Import VAT at 20% is charged on the customs value plus duty, £17,850, so it is £3,570. Import taxes total £3,920; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £350 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the powder description, ingredient statement, batch markings and certificate of analysis to the purchase specification.
Assay: check the protein result, dry-basis calculation and nitrogen factor; compare moisture and ash with the agreed limits.
Safety evidence: match contaminant and microbiological reports to the delivered lot, and review shared-line soya or milk cross-contact information.
Packaging and function: inspect seals, liners, dampness and caking; compare colour, odour, dispersion and mouthfeel with the retained sample.

What goes wrong
A protein result can look acceptable while the powder performs poorly. Different nitrogen factors obscure comparisons, moisture changes the apparent assay, and coarse particles create grit or sediment. A change in rice source or processing can alter colour and flavour. Keep a retained sample and agree how changes are approved before production.
Another failure is paperwork that describes the supplier’s standard product rather than the shipped lot. Missing batch links make test reports difficult to use. For an organic claim, confirm certificate requirements with the relevant organic control body rather than relying on the supplier’s claim alone. Hold discrepant stock apart while you resolve its identity, test evidence and intended use.

Frequently asked questions
What is the UK import duty on rice protein isolate from China?
The supplied tariff data records 2% under 3504 00 90 99, with no listed anti-dumping or countervailing duty. The zein suspension does not cover rice protein isolate.
Does rice protein isolate need veterinary checks?
The shared tariff line attaches veterinary control. Give port health and your customs broker the composition and plant-origin evidence to confirm whether veterinary checks or a declaration are required for the exact product.
What paperwork does organic rice protein need?
For organic rice isolate imported from China into Great Britain, confirm with the relevant organic control body whether a certificate of inspection is required. It is issued by the exporter’s control body; a supplier’s organic claim alone is insufficient.
What should I test before buying rice protein isolate?
Check protein with the nitrogen factor stated, moisture, ash, arsenic and other contaminants, microbiological quality and powder function. Ask port health and your laboratory about rice-specific screening.
