Look up duty rates during classification review. Cross-reference MFN against preferential treatment to confirm cost models are accurate before shipments move.
Embed live duty data in classification tools, ERP modules, or broker portals. One endpoint returns the full record: MFN rate, all preferential columns, description, units.
Accurate duty rates are the foundation of any landed cost estimate. Pull the current rate at query time — not from a stale table maintained by hand.
Poll the changelog endpoint nightly or subscribe to webhook events. Receive the diff — old rate, new rate, effective date — the same night USITC or CBSA publishes an amendment.
Both schedules use the same response structure and the same authentication token. Full API documentation →
