How to use HS Chapter 28 before buying from 1688

Use this chapter as a classification starting point, then confirm the actual product material, intended use, destination market, and official tariff source before trusting any landed-cost estimate.

Find the product family

Start from the heading group that best matches the product, then open the closest six-digit code page.

Check the destination source

Use the market official source for HTS, TARIC, commodity code, VAT/GST, duty, and import controls.

Keep the estimate conditional

Do not treat a supplier-provided HS code as final until material, use, value, and route assumptions are reviewed.
