What HTS 6907.21.10 Covers
Unglazed ceramic flags and paving, hearth or wall tiles with a water absorption coefficient by weight not exceeding 0.5 percent. These are dense, low-porosity tiles, typically porcelain, used for floors, walls, and paving. The unglazed finish distinguishes them from the glazed tiles on the adjacent line.
Notes for Importers
Water absorption is the controlling test across the 6907.2x subheadings, so importers should have lab data or manufacturer specs showing absorption is 0.5 percent or less; higher absorption pushes the tile to 6907.22 or 6907.23. Glazed versions of the same tile fall on a different line within 6907.21. Full-body unglazed porcelain tile is the classic product here; natural stone tiles are Chapter 68, not Chapter 69.

Frequently Asked Questions
What tiles fall under 6907.21.10?
Unglazed ceramic or porcelain floor, wall, and paving tiles with water absorption of 0.5 percent or less by weight, which typically means dense porcelain tile.
How do I prove the water absorption level?
Keep manufacturer test reports or independent lab results showing absorption at or below 0.5 percent. CBP can request this, and the wrong absorption bracket means the wrong subheading.
Does this include glazed porcelain tile?
No. Glazed tiles with the same low absorption are classified under other lines of 6907.21. This provision is limited to unglazed tiles.
What is the HTS code 6907.21.10 used for?
HTS code 6907.21.10 is the harmonized tariff schedule code for Unglazed. This code is used to classify and identify this product type for customs clearance, duty calculation, and trade statistics.
What is the Column 2 rate for HTS 6907.21.10?
The Column 2 rate is the tariff duty rate applicable to goods from countries that do not have normal trade relations with the United States. This rate is typically higher than Column 1 (Most Favored Nation) rates and is rarely used in modern trade due to most-favored-nation agreements.
Do I need a customs broker to import goods classified under HTS 6907.21.10?
While not always required, using a licensed customs broker is highly recommended for most imports. A customs broker can help ensure proper HTS classification, prepare customs documentation, pay duties correctly, and avoid delays or penalties. Your broker should be familiar with Stone, Ceramic, and Glass Products products.
Which countries receive special tariff rates for HTS 6907.21.10?
Multiple free trade agreements and trade preference programs provide reduced or free tariffs for eligible HTS classifications. Common programs include USMCA (Canada, Mexico), various bilateral FTAs (Korea, Australia, Singapore), GSP for developing countries, and AGOA for eligible African nations.

How does HTS code 6907.21.10 affect my import costs?
The HTS code determines the applicable duty rate (either free or a percentage/specific amount), whether your product qualifies for trade agreement benefits, any quota restrictions, and special documentation requirements. Proper classification directly impacts your import expenses, so verify the correct code with your supplier or a customs professional.
