Products classified under HTS 4411.94.00.10
Bitumen Impregnated Low-Density Fiberboard Panels
Low-density fiberboard (LDF) panels with density between 0.35-0.5 g/cm³, made from wood fibers bonded with resins and impregnated with bitumen for water resistance. Classified under HTS 4411.94.00.10 as fiberboard not mechanically worked or surface covered, specifically impregnated with bitumen. Used primarily in construction for underlayment and roofing substrates.
Bitumen-Coated Roof Underlayment Fiberboard
Fiberboard sheets impregnated with bitumen, density 0.35-0.5 g/cm³, designed as roof underlayment to provide moisture barrier in construction. Meets HTS 4411.94.00.10 criteria: not mechanically worked, not surface covered beyond impregnation, from ligneous materials. Ideal for residential and commercial roofing applications.
Water-Resistant Bitumen Fiberboard Insulation Boards
Insulation-grade fiberboard impregnated with bitumen for humidity resistance, density exceeding 0.35 but ≤0.5 g/cm³. Fits HTS 4411.94.00.10: other fiberboard, not mechanically worked, bitumen impregnated, no surface covering. Used in wall and ceiling insulation systems.
Bitumen Impregnated Bamboo Fiberboard Sheets
Fiberboard from bamboo (woody material per Chapter 44 note), density 0.35-0.5 g/cm³, bitumen impregnated for damp-proofing. Classifies under HTS 4411.94.00.10 as unworked ligneous fiberboard with bitumen impregnation. Sustainable alternative for sheathing and barriers.
Construction-Grade Bitumen LDF Sheathing Panels
Low-density fiberboard sheathing panels treated with bitumen impregnation for exterior moisture protection, density 0.35-0.5 g/cm³. HTS 4411.94.00.10 applies to this not mechanically worked, not surface covered product of wood fibers. Standard size for wall sheathing in framing.
Acoustic Bitumen-Impregnated Fiberboard Panels
Fiberboard panels with bitumen impregnation for sound absorption, density controlled at 0.35-0.5 g/cm³, not mechanically worked. Precisely matches HTS 4411.94.00.10 definition for low-density impregnated fiberboard. Used in studio and theater ceiling applications.
Damp-Proof Course Bitumen Fiberboard
Specialized fiberboard for damp-proof courses in masonry, bitumen impregnated throughout, density 0.35-0.5 g/cm³. Classifies under HTS 4411.94.00.10 as unworked, bitumen-impregnated low-density fiberboard from ligneous materials. Prevents rising damp in foundation walls.
Bitumen Treated Wood Fiber Underfloor Panels
Underfloor heating system panels of bitumen-impregnated wood fiberboard, density 0.35-0.5 g/cm³, untreated surfaces. HTS 4411.94.00.10 classification for low-density, not worked, bitumen fiberboard. Provides thermal mass and moisture resistance.
Industrial Bitumen-Impregnated Partition Board
Factory partition walls made from bitumen-impregnated fiberboard, 0.35-0.5 g/cm³ density, raw unfinished surfaces. Fits HTS 4411.94.00.10 exactly as low-density, unworked, bitumen-treated ligneous board. Temporary industrial divider applications.
