HS Code 851821

HS code 851821 is the World Customs Organization 6-digit HS 2022 subheading for "Microphones and stands therefor; loudspeakers, whether or not mounted in their enclosures; headphones and earphones, whether or not combined with a microphone, and sets consisting of a microphone and one or more loudspeakers; audiofrequency electric amplifiers; electric sound amplifier sets : Loudspeakers, whether or not mounted in their enclosures : Single loudspeakers, mounted in their enclosures". The first two digits (85) are the chapter — Electrical machinery and equipment; sound and TV recorders and reproducers — and digits 3-4 (8518) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 851821 include speaker, bookshelf speaker, enclosure speaker, single speaker and similar items matching single loudspeakers. 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 (851821) 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.
