hscode-worksheet-extension
Chrome extension that generates US HTS codes and customs worksheets offline for eBay exporters; Japanese.
What it does
A Japanese-language Chrome extension for eBay exporters: a wizard per product category proposes a six-digit HS and ten-digit US HTSUS code, prints an A4 customs worksheet, checks CPSC eFiling lists and fills a TSCA certificate. Loaded unpacked in developer mode; the core works offline, an OpenAI API key adds optional AI help. Codes are candidates only, the exporter stays responsible; no licence.
Licence unknown: we found no licence we could recognise. Check with the maintainers before you reuse the code.
Where it fits on the map
Not on the map: for individual taxpayers.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
