HS Code 040390

HS code 040390 is the World Customs Organization 6-digit HS 2022 subheading for "Buttermilk, curdled milk and cream, yogurt, kephir and other fermented or acidified milk and cream, whether or not concentrated or containing added sugar or other sweetening matter or flavoured or containing added fruit, nuts or cocoa : Other". The first two digits (04) are the chapter — Dairy produce; eggs; natural honey; edible products of animal origin — and digits 3-4 (0403) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 040390 include buttermilk, kefir, sour cream, cultured buttermilk, fermented milk and similar items matching buttermilk. The correct code still depends on the product's material, function and intended use.

Duty is set by the destination country, not by the 6-digit HS code alone. Start from the official tariff of your market — USITC HTS (US), TARIC / Access2Markets (EU), GOV.UK Trade Tariff (UK), CBSA (Canada), ABF (Australia) or Singapore Customs — and look up the full national code with China as the country of origin.

The first 6 digits (040390) are the same worldwide under the WCO Harmonized System. Beyond that, each country extends the code (HTS in the US, TARIC in the EU, etc.) and sets its own duty and tax rates.

Treat a supplier-provided code as a clue, not a final classification. It can be incomplete, China-export-specific, or mismatched to your destination's rules. Verify against the official tariff and your product's actual material and use.
