Source verified
The only customs database that hands back a receipt to the original government source on every single line.
The most intelligent customs database on planet Earth.
The problem 02
Global trade runs on one code. Most tools still get it wrong.
Customs classification is a multi-trillion-dollar problem hiding in plain sight. Here is the case, and every number is traced to a primary authority or a named report.
The scale
$34.65T
Global trade in goods and services in 2025. Every shipment of goods needs an HS code, and the code sets the duty.
WTO · World Trade Statistics 2025The scope
98%
of world merchandise trade is classified with HS codes, maintained by the WCO and used by 200+ countries.
World Customs OrganizationThe leak
10-digit
A 6-digit HS code is shared by 200+ countries, but duty is set at the full 10-digit national line. Stop at six and you pay the wrong rate.
World Customs OrganizationThe penalty
4×
US Customs can charge up to four times the duty for gross-negligent classification, and the full value of the goods for fraud.
19 U.S.C. § 1592The friction
94%
of surveyed cross-border businesses face shipping delays from incorrect classification or documentation.
Avalara · Cross-Border Ecommerce 2023/24The complexity
73%
of product categories now fall into tariff-sensitive classifications, after the 2025 tariff changes.
ePost Global, 2025 · 15.6M shipmentsThe cost
€2B
Undervaluation and false classification cost EU customs an estimated two billion euros in duty in a single case.
OLAF · EU Court of Justice, C-213/19Why not just AI
A language model pattern-matches; it does not read the tariff schedule. Harmonova self-verifies every code against the official source, so the answer holds up in an audit.
The legacy problem 03
Customs is stuck in legacy mode. Your margins shouldn't be.
The capabilities 04
The customs engine, drawn to spec.
Six things legacy customs tools can't do. Open, fast, and self-verifying.
Sourced, not guessed
Every HS code maps to the official schedule it came from: USITC, EU TARIC, UK Trade Tariff.
AI classification, sub-200ms
Product description to HS-6 plus full HTS-10, with a confidence score and the reasoning behind it.
Origin-aware duty stack
Section 301, Section 122, IEEPA, FTAs. The right stack for the right country, effective-dated.
Live tariff intelligence
Re-checked against the official feeds every day. When a measure terminates, the engine knows.
Self-verifying engine
Independent reconciliation against USITC, plus a reference-basket gate that catches drift before you do.
Open + API-native
MIT-licensed database with REST + MCP. One endpoint classifies, resolves duty, and returns a source for every number.
The data engine 05
A verified, self-maintaining duty database.
Not an AI wrapper. It re-checks every official source and shows its work.
