What is a customs tariff number?

A customs tariff number – also known as HS code (Harmonized System code) – is an internationally standardized numerical code used to classify traded goods. It determines the customs duties, import/export restrictions, and documentation required for a specific product.

Customs tariff numbers in eCommerce

In eCommerce fulfillment, customs tariff numbers are essential for cross-border shipping. Each product must be correctly classified to ensure legal compliance, accurate customs clearance, and smooth delivery. With everstox, tariff numbers are integrated into product data and automatically transmitted to the carrier for customs processing – reducing delays, fines, and manual errors in international shipments.

Example for a customs tariff number

A D2C fashion brand ships accessories to Switzerland. everstox uses the product’s customs tariff number (e.g. 62171000 for textile accessories) to ensure the correct duty rate and customs declaration – all handled automatically through the platform.
