How this service works
Japan Customs import tariff lines for an HS heading or subheading (e.g. 8703 or 8703.21) from the official chapter table: description, general tariff rate, temporary rate, WTO rate and unit. Only the English chapter page for the 2026-04-01 schedule is used; the chapter table is decoded from Shift_JIS.
Output
A JSON object containing the queried HS code, a count of matching tariff lines, and an array of lines each with HS subheading, statistical code, description, general tariff rate, temporary rate (if any), WTO rate (if any), and unit of measure, plus the source URL on customs.go.jp and the timestamp of the check.
Example use cases
Automotive import duty check
“I'm importing passenger cars with engine displacement under 1,000 cc into Japan — can you look up the Japan customs tariff for HS 8703.21 and tell me the general rate and whether there's a WTO rate?”
Electronics tariff classification research
“We're sourcing laptops from overseas and need to know Japan's import duty rates under HS heading 8471 for the 2026 schedule — can you pull all the tariff lines and rates?”
Trade compliance landed cost estimate
“Help me figure out the Japan customs duty rates for HS heading 2204 (wine) so I can estimate landed costs — I need the general rate, temporary rate, and unit for each tariff line.”
Technical details
Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/logistics/japan-customs-tariff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need machine-readable Japan import tariff rates for a specific HS heading or subheading from the official 2026-04-01 Japan Customs schedule, especially when you need general, temporary, and WTO rates in one call. Prefer this over manual scraping of customs.go.jp when building trade compliance tools, landed cost calculators, or customs classification workflows targeting the Japanese market.
Side effects
- Invalid or malformed HS code returns an error or empty lines array
- HS heading not found in the 2026 schedule returns zero lines
- Source page encoding issues (Shift_JIS decoding failure) may cause garbled descriptions
- Upstream customs.go.jp page unavailability causes fetch failure
- Requesting a chapter not covered by the English schedule may return no data
