Classification of felt board under HS 4805.50
Felt board, specifically referred to in the tariff as felt paper and paperboard, is classified under HS code 4805.50. This classification is part of Chapter 48, which covers paper and paperboard articles. Heading 4805 is reserved for other uncoated paper and paperboard, in rolls or sheets, that have not been further worked than specified in the chapter notes. Felt paperboard is a thick, porous, and relatively heavy material often manufactured from waste paper, wood pulp, or a mixture of vegetable fibers and textile scraps. It is primarily used as a structural base for roofing membranes, flooring underlayment, or as an insulating layer in construction. It is distinguished from textile felt (which falls under Chapter 56) by its manufacturing process; while textile felt is made by interlocking fibers through heat, moisture, and mechanical action, felt paperboard is produced using the traditional papermaking process on a continuous machine. The absence of a coating or impregnation at the time of initial classification is what places it specifically under 4805.50.

Codes often confused with 4805.50

The distinction is based on whether the product is "paper" (Chapter 48) or "textile" (Chapter 56). Another common error is 4811, which applies if the felt board has been coated, impregnated, or covered with bitumen or asphalt for roofing.

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).
