Temporal legal research for customs and trade law
Taridex reconstructs the HTS, CFR, and trade authorities in force when a ruling was issued — diffs them against today's law with LegalSnapshot, HTS lineage traversal, and a seven-stage citation trace you can export.
Deterministic, traceable, built on a verified authority corpus — not probabilistic legal chat.
Audience
Taridex is for customs brokers, trade attorneys, and import compliance teams who need to know whether a CBP ruling still governs today's tariff lines — not for duty calculators, entry filing, or general legal chat.
If you need pass/fail compliance scoring or automated classification filing, this is not that product.
Proof — HQ 088500
Every conclusion links to ruling-date authorities, lineage edges, and an exportable trace — certified on staging, not slideware.
Built for customs brokers, trade attorneys, and import compliance teams.

| HTS | Edition | Rate |
|---|---|---|
| 8424.89.00 | HTS-1991 (February 1991) | 3.7% general |
This is the February 1991 HTS edition at ruling date — automatically bound, not manually looked up.
Staging GET /v1/legal-snapshot/088500 → HTTP 200 in 3.09 s (W5-A1).
SUPERSEDED — ruling authority no longer reliable for current classification.
Relevance 0.279 — diagnostic only; does not affect retrieval rank.
MODIFIED_BY → H237855
Staleness is visible before you open anything — not buried in an advanced tab.

Workflow
Three stages — not a feature grid. Every investigation terminates in a governed export, not a chat log.
Submit ruling number or classification research context. Policy routing selects CLASSIFICATION, origin, or remedy channels — deterministic, not freeform AI.
LegalSnapshot binds ruling-date HTS and CFR authorities, traverses lineage, classifies impact (SUPERSEDED, UNCHANGED, …), and assembles a seven-stage citation trace.
Research package — markdown, JSON, ZIP — with payload hash and provenance. Work product for client files and audit response.
Trust
Demo environment certified (2026-06-09). Production deployment follows design partner validation. Taridex does not replace CROSS as the official ruling registry.
SHA-256 release integrity verified across staging and production — 2026-06-08.
Ruling-date HTS-1991 authority reconstructed; successor codes identified. Certified on staging in 3.09 s.
Query → result pipeline with ranking preserved — deterministic, exportable provenance.
JSON, markdown, ZIP — 8/8 staging harness PASS; payload SHA-256 matches on replay.
Executive path SC-01–SC-07 PASS on staging; 6.11 s automated walkthrough.
Governed retrieval and temporal graph — not probabilistic legal chat.
Cloudflare Access + role-based API controls; no training on your exports.
Documented gaps in CFR depth, SEC301, and Part 152 — ask us for the gap registry.
Differentiation
Westlaw tells you what was said; Taridex tells you whether it still holds — with the authorities in force on both dates.
| Tool | Gap |
|---|---|
| CROSS | Official registry — no temporal diff or HTS lineage at ruling date. |
| Westlaw / Lexis+ | Case-law AI — no customs ruling-date HTS bind. |
| ChatGPT / Claude | Probabilistic — no HTS lineage export or SUPERSEDED taxonomy. |
| Descartes / duty tools | Current classification — not ruling validity research. |

Demo
Watch a 1991 ruling bind to February 1991 HTS, traverse the 2007 split, detect H237855 modification, and export a research package with full citation trace.
After your demo: apply for a design partner pilot (3 external slots).
