The connected HTS, notes, overlays, AD/CVD, rulings, CSMS, and orders — all cross-linked.
Who it's forImporterBrokerConsultantTrade Lawyer
01
Every authority, one graph
HTS lines, notes, Chapter 99 overlays, AD/CVD, CROSS rulings, CSMS, quota bulletins, and proclamations — ingested and cross-linked, so the ruling behind a code is one hop away, not another search.
02
301, 232 and IEEPA, structured
Temporary duties are modelled as first-class overlays — each with its governing note, country scope, rate, and effective window — kept current from published editions and the CSMS bulletins that land before them.
03
Point-in-time, by design
Everything is bitemporal: a lapsed duty drops out of today’s lookups but still resolves correctly for a shipment from last February.
