HS Code 381700

HS code 381700 is the World Customs Organization 6-digit HS 2022 subheading for "Mixed alkylbenzenes and mixed alkylnaphthalenes, other than those of heading 2707 or 2902". The first two digits (38) are the chapter — Miscellaneous chemical products — and digits 3-4 (3817) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 381700 include alkylbenzene, alkylnaphthalene, linear alkylbenzene, LAB, heavy alkylate and similar items matching mixed alkylbenzenes and mixed alkylnaphthalenes. 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 (381700) 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.
