Tariff and HS code data

Tariff and HS code data covers the duty rates, taxes and rules that apply when goods cross borders, together with the product classifications they depend on. Importers, exporters, customs brokers, e-commerce platforms and trade compliance software use it to calculate landed costs, classify products and assess the impact of tariff changes and trade agreements.

Typical fields

• HS code and national tariff line with description
• Importing country and effective date
• Duty rate type: ad valorem, specific or compound
• Preferential rates under trade agreements and rules of origin
• Additional duties such as anti-dumping, countervailing or retaliatory tariffs
• VAT or sales tax, excise and quotas
• Legal source reference

Sources and collection

Tariff data is compiled from official customs tariffs, government gazettes, trade agreement schedules and WTO notifications, then structured into a consistent schema. The difficulty is keeping it current: rates and additional duties can change at short notice, and national tariff lines are revised with each HS edition. Classification products map product descriptions to codes, often with machine learning plus expert review.

Delivery and pricing

Delivery is via an API for landed-cost calculations, bulk files of tariff schedules, or classification services. Price depends on the number of countries, update frequency, API volume and whether rules of origin and classification support are included.

Before you buy

• Check how quickly rate changes are reflected and how you are notified.
• Confirm the national tariff line depth for your countries.
• Ask whether additional and trade-remedy duties are included.
• Check rules-of-origin coverage for the agreements you use.
• Ask about accuracy and responsibility for classification suggestions.
