HS Code Classification Software Built for Accuracy

Harmonized System (HS) codes underpin every cross-border shipment. A single misclassification can trigger duty underpayments, customs delays, or regulatory penalties worth far more than the goods themselves.

TTClassify is HS code classification software built specifically for customs teams, freight forwarders, and global trade compliance professionals who need reliable, auditable results at scale.

Unlike generic lookup tables or spreadsheet-based workflows, TTClassify uses a structured, rules-based classification engine trained on millions of customs rulings. Every classification comes with a confidence score, supporting rationale, and a full audit trail — so you're always ready for a customs review.

What Is HS Code Classification?

The Harmonized System (HS) is an internationally standardised nomenclature for goods traded globally, maintained by the World Customs Organisation (WCO). HS codes are 6-digit codes (extended to 8–10 digits by individual countries) that customs authorities use to determine applicable duty rates, import/export restrictions, and compliance requirements for every shipment.

Correct HS code classification is a legal obligation for importers and exporters. It directly determines how much duty you pay, whether a shipment is eligible for trade agreement preferential rates, and whether goods require special licences or permits.
