HS Code 843031

HS code 843031 is the World Customs Organization 6-digit HS 2022 subheading for "Other moving, grading, levelling, scraping, excavating, tamping, compacting, extracting or boring machinery, for earth, minerals or ores; piledrivers and pile extractors; snowploughs and snowblowers : Coal or rock cutters and tunnelling machinery : Selfpropelled". The first two digits (84) are the chapter — Nuclear reactors, boilers, machinery and mechanical appliances; parts — and digits 3-4 (8430) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 843031 include roadheader, tunnelling machine, rock cutter, coal cutter, continuous miner and similar items matching selfpropelled. 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 (843031) 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.
