Sourcing Neohesperidin dihydrochalcone from China

Duty on unblended neohesperidin dihydrochalcone

Heading 2938 covers glycosides and their salts, ethers, esters and other derivatives. For unblended neohesperidin dihydrochalcone, the residual line 2938 90 90 90 is the provisional classification to check. The table shows buying specifications under that same line, rather than separate tariff subdivisions. For wider heading context, see hesperidin sourcing.

Read from the UK Trade Tariff on 4 October 2026, the supplied residual line carries 6% duty for China, with no anti-dumping or countervailing measure shown. Its suspension names a purified steviol glycoside for beverage manufacture, not neohesperidin dihydrochalcone. The tariff attaches an export waste control. Waste shipment controls apply only to waste; confirm any waste-related requirement with your customs broker before shipping or returning material.

Confirm the commodity code using the complete chemical identity, assay, composition and intended use. Declare any carrier or added sweetener rather than treating a blend as the pure substance. Keep the supplier specification and batch certificate with the classification enquiry.

Specify identity, assay basis and formulation behaviour

State neohesperidin dihydrochalcone in full on the purchase specification. Ask the supplier to distinguish it from hesperidin and neohesperidin, and disclose any carrier or other ingredient. Agree the assay method, whether the result is measured on a dried basis, moisture, particle size, residual-solvent testing and packaging.

Food additives need authorisation before they can be placed on the market in Great Britain. Before ordering for food production, check the intended food category, function and addition level against the applicable authorisation. Ask a laboratory to compare the proposed specification with its terms. Trial sweetness, aftertaste, dissolution and dispersion in your actual formulation before approving the sample.

Worked duty example

Illustrative example, not a quote: An illustrative small-business trial batch of unblended neohesperidin dihydrochalcone under 2938 90 90 90, invoiced at £3,500 free on board, with £1,500 of freight and insurance to the UK. The customs value is £5,000. Duty at 6% is £300. Import VAT at 20% is charged on the customs value plus duty, £5,300, so it is £1,060. Import taxes total £1,360; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £300 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: compare the batch sample with the approved material and confirm the laboratory distinguishes neohesperidin dihydrochalcone from similarly named substances.

Assay: compare the certificate and independent result using the agreed method and moisture basis; investigate a mismatch before releasing the batch.

Formulation: repeat the agreed dissolution, dispersion and taste trial in your product, checking for sediment, uneven mixing or an unexpected aftertaste.

Packing and records: check seals, liners, moisture damage and caking; match every container's product identity and batch reference to the certificate. Use testing and certification support to define the laboratory brief.

What goes wrong

A similar product name can conceal the wrong substance, while an undisclosed carrier can make the delivered powder differ from the approved sample. Comparing a dried-basis assay with an as-received result can also create a misleading apparent pass or failure.

A powder may match its assay certificate yet perform poorly in the buyer's mixing process. Keep the approved sample, testing method and formulation trial as acceptance references. Hold material with damaged seals, inconsistent batch records or unexplained results while the supplier investigates. See quality inspection explained.
