Customs Duty Rates API

Retrieve import customs duty rates for any HS code entering any country — with MFN applied rates, preferential FTA rates, import VAT/GST, additional duties (anti-dumping, safeguards, excise), de minimis thresholds, and non-tariff restrictions (import licensing, CITES, quotas) all in a single response.

API Overview

This API returns comprehensive import duty information for a specific Harmonized System (HS) classification entering a specific destination country. Unlike single-dimensional tax APIs, customs duty depends on the combination of what is being imported (the HS code) and where it is being imported to — so this API takes two parameters: the destination country and the HS code (6-digit minimum, up to 10-digit national extensions). The response covers the MFN applied rate, the calculation basis (ad valorem / specific / compound), all notable preferential rates under free trade agreements, import VAT/GST layered on top, additional duties such as anti-dumping and safeguard measures, and critical non-tariff considerations like de minimis thresholds, import licensing, quotas, and CITES restrictions. Freight forwarders, customs brokers, ERP systems, cross-border ecommerce platforms, and logistics software rely on this API for landed-cost calculation, tariff planning, and clearance preparation.

Full Duty Stack

Every response includes MFN applied rate, duty basis, preferential FTA rates, import VAT/GST, and additional duties (anti-dumping, safeguard, countervailing, excise) — the complete picture needed for landed-cost calculation.

Preferential Rate Coverage

Notable FTAs that could lower the rate are surfaced in prose form with specific agreement names and preferential rates — with the standard reminder that preferential rates require compliance with each FTA's rules of origin.

Non-Tariff Restrictions

Import licensing requirements, tariff-rate quotas, CITES permits, dual-use export controls, SPS certificates, and outright bans are surfaced in a dedicated field — often the actual shipment blocker rather than the duty rate itself.

Premium API

This is a premium API that uses advanced AI analysis across national tariff schedules, WTO concession bindings, free trade agreements, customs authority publications, and anti-dumping orders to provide comprehensive import duty information for any HS-code-and-country combination.

These examples demonstrate the real complexity of international customs duty. A US t-shirt import faces both MFN tariff and Section 301 surcharges if China-originated, plus UFLPA forced-labor presumption issues; UK wine pays specific duty plus substantial alcohol excise plus VAT on the stacked total; Japanese car imports show 0% MFN masking a complex stack of environmental and weight taxes; and Australia's A$1,000 de minimis threshold defines the line between casual ecommerce and formal customs entry. Preferential rates require compliance with each FTA's rules of origin — claiming them without proof of origin results in rejection and potential penalties.
