HS Code for Fiber cement sheets

HS code 6811.82 is designated for sheets, panels, tiles, and similar articles made of cellulose fiber-cement that are not corrugated and do not contain asbestos. This classification is based on the physical form of the product—specifically its flat or planar nature—and its chemical composition. These articles are widely used in the construction industry for cladding, roofing, and flooring. The classification under 6811.82 is specific to non-asbestos materials; if the product contained asbestos, it would be classified under 6812. The distinction between 6811.81 (corrugated) and 6811.82 (flat) is critical for accurate customs declaration and duty application. These sheets are often produced using the Hatschek process, where layers of fiber-cement slurry are built up on a drum before being flattened and cured. Because they are used as primary building materials, they are subject to specific standards for fire resistance and durability. Importers must ensure that the product is truly "flat" to qualify for this code, as any significant corrugation would shift the classification to 6811.81. Furthermore, the absence of asbestos must be verifiable through technical data sheets to avoid the more restrictive regulations associated with heading 6812.

Products Included

• Flat building sheets for exterior cladding
• Fiber cement siding panels (lap siding)
• Floor underlayment boards
• Ceiling tiles made of fiber cement
• Decorative interior wall panels
• Backer boards for tile installation

Common Misclassification

Frequently confused with 6811.81, which is reserved for corrugated sheets used primarily for roofing. It is also sometimes misclassified under 4411 (fiberboard of wood), though fiber cement is mineral-based rather than purely wood-based. Another error involves 6810.19, which covers tiles and flagstones of cement or concrete, but lacks the specific cellulose fiber reinforcement required for 6811.

FAQ

What is the HS code for fiber cement siding?

Fiber cement siding is classified under HS code 6811.82, provided it is in the form of flat panels or sheets.

Does this code include asbestos sheets?

No, any sheets containing asbestos are classified under heading 6812. HS code 6811.82 is strictly for non-asbestos cellulose fiber-cement products.
