SkuWatch Tariff Archive
Structured, source-linked archive of US tariff and import-rule changes since 2018, organized by HTS code.

What this site contains
- Per-code pages: /hts/{dotted-code}/ with rates and linked policy history.
- Per-measure pages: /measure/{slug}/ with lifecycle status and source links.
- Monthly archives: /archive/{yyyy-mm}/ with action clusters.
- Topic hubs: /basis/{basis}/ and /origin/{country}/.

How to locate a page
HTS code 9503.00.90 => https://skuwatch.app/hts/9503.00.90/
(canonical routes keep dots; direct 10-digit heading children have their own pages, while 10-digit children nested under an 8-digit line are represented on that 8-digit page unless directly linked)

Data policy
Updated per current build snapshot; every fact links to official sources (Federal Register, CBP, BIS, USITC).
Data coverage is tracked from measure snapshots with dates in page metadata.
