Product classification
HS code for Fiber cement sheets: 6811.82
Cellulose fibre-cement, articles or the like, sheets, panels, tiles and similar articles (other than corrugated sheets), not containing asbestos.
Classification of fiber cement sheets under HS 6811.82
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.

Codes often confused with 6811.82
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
