BorderRev · Model 1 of 5

The Classifier
that can be audited.

BorderRev's HS classification verification engine returns a verdict on every declared customs line — and grounds it in the exact legal authority that supports it. Built for customs administrations who need findings that stand up in a tribunal, not just a dashboard.

Levofloxacin contains an oxazine ring — a heterocyclic system with both nitrogen and oxygen heteroatoms. Chapter 29 Note 8 directs such compounds to heading 29.34, not 29.33.

Misclassification quietly drains national revenue.

The Harmonised System is genuinely complex — over five thousand commodity groups, layered with Section Notes, Chapter Notes, General Interpretative Rules, and national extensions. At national volumes, manual verification of every declaration is not viable.

Rule-based automation alone produces false positives that can't be defended in an appeal. Generic AI tools produce answers without accountability. Neither is good enough for a revenue authority.

Surfaced in a no-risk trial run against a national customs administration's historical declarations. Every finding cited.

From declaration to defensible verdict.

Three resolution paths handle every line at machine speed. The simplest path that produces a defensible answer wins — so the system gets faster and more autonomous the more it sees.

Memory

Most declarations have a near-identical predecessor. When a match is found, the cached verdict — with its original citations — is returned in milliseconds, without re-running the reasoning.

Rules

Deterministic legal rules encode the WCO Notes and General Interpretative Rules. When a rule resolves a case, the answer is a direct citation of the legal text — no inference required.

Reasoning

The residual tail of genuinely ambiguous cases is sent to the AI adjudicator. Every output is validated against the knowledge repository before it becomes a verdict.

Every finding carries its own evidence.

A built-in triage layer.

Confidence scores map directly to downstream workflow actions. No manual triage queue needed — verdicts route themselves.

High · Incorrect

Priority audit queue

Immediate examination or post-clearance recovery action. Strong evidence, clear citation.

High · Correct

Auto-clear

No further action required. Result is cached so the same declaration is never re-verified.

Medium · Incorrect

Standard audit queue

Risk-scored alongside other signals — valuation, origin, trader profile.

Ambiguous

Specialist review

A human analyst is assigned, with full case context. Their decision is written back to memory.

01 · AUDITABLE BY DESIGN

The system is the audit log.

Every verdict carries a live chain back to the specific legal instrument that supports it — the Note, the General Interpretative Rule, the published ruling. The chain is structured, not narrative: source type, publication date, retrieval date, ingestion run.

When a finding is challenged in a tribunal, the legal basis is already documented. There is no separate evidence-gathering step.

02 · MULTILINGUAL BY DESIGN

Three Spanish, Arabic, and English variants of the same product resolve to one verdict.

A Spanish declaration of "tabletas de levofloxacino" and an Arabic declaration of "أقراص ليفوفلوكساسين" both reach the same canonical record without a translation step.

Once the canonical record is established, every supported language hits the same cached decisions. You don't re-verify a product for every language separately.

03 · FUTURE-PROOF

HS 2027 already coexists with HS 2022.

On 1 January 2027, every customs administration in the world transitions to a new nomenclature edition. Historical decisions are keyed to the old edition; new declarations to the new one.

The Classifier already serves both editions in parallel. Straightforward 1:1 code mappings carry forward automatically. Ambiguous 1:N mappings are flagged for review ahead of the cutover.

04 · SOVEREIGN BY DESIGN

No declaration data needs to leave your control.

The Classifier is built to run inside your own infrastructure. The classification pipeline, the knowledge repository, the decision cache — all on-premises.

Where the AI adjudicator is used, only anonymised classification metadata leaves the deployment — no raw goods description, no declarant identity, no commercial values. For administrations with strict residency requirements, an air-gapped mode uses a locally hosted reasoning model instead.

05 · A SYSTEM THAT COMPOUNDS

The more declarations it sees, the smarter it gets.

Every verdict — cache hit, rule-resolved, AI-adjudicated, or human-resolved — is written back to memory. Over time, the share of declarations resolved instantly from memory grows, while the residual tail that needs fresh reasoning shrinks.

Edge cases the system had to escalate yesterday become routine cache hits tomorrow. Accuracy compounds without retraining; throughput improves without scaling spend.
