HS Code 382550

HS code 382550 is the World Customs Organization 6-digit HS 2022 subheading for "Residual products of the chemical or allied industries, not elsewhere specified or included; municipal waste; sewage sludge; other wastes specified in note 6 to this chapter : Wastes of metalpickling liquors, hydraulic fluids, brake fluids and antifreeze fluids". The first two digits (38) are the chapter — Miscellaneous chemical products — and digits 3-4 (3825) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 382550 include waste hydraulic fluid, waste brake fluid, waste antifreeze, pickling liquor waste, spent metal pickling solution and similar items matching wastes of metalpickling liquors. 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 (382550) 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.
