Japan HS Code

HS Code 840810: Marine propulsion engines in Japan

Q: Is HS code 840810 the same across all countries?

Yes — up to the 6-digit level, HS code 840810 is the same in every WCO member country. Beyond 6 digits, each country extends the code for national tariff and statistical use. Japan extends it under Japan HS / Statistical Code.

Q: What system does Japan use to classify HS code 840810?

Japan classifies products under the Customs Tariff Schedules of Japan (Japan HS / Statistical Code; locally 実行関税率表), which extends HS codes to 9 digits. The first 6 digits align with the WCO Harmonized System, and the rest cover national tariff and statistical needs.
