A Dropshipper's Guide to HS Codes and Import Tariffs in 2026

What is an HS Code?

Harmonized System (HS) codes are standard 6-to-10 digit numbers used by customs authorities worldwide to classify products, determine import tariff rates, and enforce safety regulations. Incorrect classification is one of the leading causes of customs delays and fines.

How to Find and Apply HS Codes

When preparing commercial shipping invoices for international parcels, follow these classification guidelines:

• Classify by Material and Function: HS codes are highly specific. For example, a plastic phone case has a different code than a leather phone case. Ensure your descriptions match the exact material.
• Use Sourcing Extension Databases: GP Sourcing's extension helps catalog product materials and suggest correct HS codes, preventing classification errors.
• Ensure Consistency: The HS code on your customs invoice must match the description on the package label to pass automated security checks.
