HS Code (Harmonized System Code)

TL;DR: An HS Code is a standardized number that tells customs what a product is. It decides which duty rate and import rules apply to your goods.

The Harmonized System is maintained by the World Customs Organization and used by most countries. The first six digits are shared internationally. Each country then adds its own digits for more detail, so a full national code is often eight or ten digits long. The same product may therefore have slightly different codes on the export and import side.

Glass mosaic tiles are commonly classified under heading 7016, which covers glass paving blocks, tiles, and small glass cubes for mosaic work. However, the exact national code depends on the product and your country’s tariff schedule. Ceramic or stone mosaics fall under different headings. The buyer must confirm the correct code with their customs broker.

The HS Code affects more than duty. It can trigger extra checks, licenses, anti-dumping measures, or special labeling rules. A wrong code can lead to underpaid duty, penalties, or goods held at the port.

A practical tip is to agree on the HS Code with your supplier before shipping, so the Commercial Invoice, the Certificate of Origin, and the export declaration in China all use a consistent classification. If your importing country offers binding tariff rulings, getting one for a new product line can remove doubt for future shipments. See also Customs Clearance and Import Duty and Taxes.
