Impregnated Softboard Insulation Panels

Soft, low-density fiberboard (≤0.5 g/cm³) panels impregnated with bitumen for enhanced thermal insulation and damp-proofing in walls and floors. HTS 4411.94.0050 applies as it's other fiberboard, bitumen-impregnated, without mechanical processing or additional surface layers. Commonly used in energy-efficient building projects.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

4411.93Lower: 13.9% vs 35%

If density between 0.5-0.8 g/cm³

Medium-density fiberboard range applies, changing the 'other' density subheading.

6811.82.00Same rate: 35%

If made from vegetable fibers other than wood with binders

Non-wood ligno-cellulosic fiberboards with resins fall under Chapter 68.

4418.40.00Higher: 38.2% vs 35%

Import Tips & Compliance

Include material safety data sheets (MSDS) detailing bitumen content <3% if applicable; ensure uniformity in panel density via sampling

Watch for reclassification if panels exceed density limit during inspection

Bitumen-Impregnated Low-Density Fiberboard Sheathing Panels

These are low-density fiberboard panels (density ≤0.5 g/cm³) made from wood fibers, impregnated with bitumen for water resistance, used primarily as exterior sheathing in construction. They fall under HTS 4411.94.0050 because they are not mechanically worked or surface-covered beyond the bitumen impregnation, meeting the specific criteria for this subheading. The bitumen treatment provides essential protection against moisture without altering the base material's classification.

Bitumen-Coated Wood Fiberboard Roofing Underlayment

Low-density fiberboard sheets impregnated with bitumen, designed as underlayment beneath roofing materials to prevent moisture penetration. Classified under HTS 4411.94.0050 due to its wood fiber composition, density not exceeding 0.5 g/cm³, and lack of mechanical working or surface coverings other than bitumen. This makes it ideal for residential and commercial roofing applications.

Bitumen-Treated Lignocellulose Damp-Proof Course Boards

Low-density boards from ligneous materials impregnated with bitumen, used as damp-proof courses (DPC) in foundation walls to block rising moisture. Fits HTS 4411.94.0050: fiberboard of ligneous materials, density ≤0.5 g/cm³, bitumen-impregnated, not mechanically worked. Essential for masonry construction.

Water-Resistant Bitumen Fiberboard Partition Panels

Unworked low-density wood fiberboard panels impregnated with bitumen for interior partitions in humid environments like bathrooms. Under HTS 4411.94.0050 for its density ≤0.5 g/cm³, bitumen treatment without mechanical or surface work. Provides lightweight, moisture-resistant dividing walls.

Bitumen-Impregnated Bamboo Fiberboard Sheets

Low-density fiberboard from bamboo (woody material per Chapter 44 note), impregnated with bitumen for outdoor shed lining. HTS 4411.94.0050 covers it as ligneous material fiberboard, ≤0.5 g/cm³, untreated beyond impregnation. Eco-friendly alternative for temporary structures.

Soft Bitumen Fiberboard Soundproofing Backing

Low-density fiberboard impregnated with bitumen to dampen sound vibrations, used as backing for studio walls and machinery enclosures. Matches HTS 4411.94.0050: other fiberboard ≤0.5 g/cm³, bitumen only, no working. Enhances acoustic isolation in buildings.
