Our Mission

We Built the Intelligence Layer for Global Commerce.

Harmonizer was born from a single observation: Customs Brokers are overloaded with data, and importers are exposed to massive financial risk—all because HTS classification is still mostly a manual, error-prone process.

By applying Large Language Models (LLMs) to the General Rules of Interpretation (GRI), we've created a system that replicates the logic of expert customs brokers at machine speed. We don't just provide codes—we provide the entire legal reasoning trail.

The Industry Problem

Manual Classification is a 45-Minute Gamble.

Every wrong HTS code is a potential CBP fine, a supply chain delay, or a lost client. The risks are real, and they compound at scale.

Time Drain

A single SKU takes a broker 45-55 minutes to manually classify through HTS PDFs, GRI analysis, and historical ruling cross-checks. For firms handling 1,000+ items, this is unsustainable.

Legal Liability

CBP requires brokers to demonstrate "Reasonable Care" in every classification decision. Manual processes create thin, inconsistent audit trails that don't hold up under scrutiny.

Scaling Bottleneck

Brokerage growth is capped by headcount. To classify more shipments, firms must hire more staff—each new hire bringing new liability vectors and more training overhead.

Our Principles

What Drives Us

Precision Over Speed

We happen to be fast, but our core obsession is accuracy. A wrong code delivered in 2 seconds is still a wrong code.

Radical Auditability

Every decision our AI makes is documented with citations. You can always see exactly why a code was assigned.

Broker-First Design

We built this with customs professionals, not around them. Every feature exists because an expert told us they needed it.

Always Current

Trade regulations change constantly. Our engine is updated continuously to reflect the latest HTSUS supplements and CBP rulings.
