Coated Compressed Cork Wall Insulation Panels
Pre-cut panels of compressed cork with a protective coating, ideal for interior wall insulation in residential and commercial buildings. Classified under HTS 4504.10.20.00 due to their compressed cork composition and primary function as thermal insulation. The coating enhances moisture resistance without altering the base classification.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If shaped into specific forms like tiles or non-sheet geometries
Other shapes of agglomerated cork products, including tiles, are covered under 4504.90 rather than sheet insulation.
If fiberboard binders dominate over cork
Medium density fiberboard (MDF) with minor cork is classified under wood-based panels in Chapter 44.
If plastic coating exceeds 50% by weight
Predominantly plastic-coated articles shift to Chapter 39 plastics classification.

Import Tips & Compliance
• Include technical datasheets specifying coating type (e.g
• acrylic or latex) and insulation R-value to support classification
• Ensure panels are not shaped as tiles; tile forms may require review under other subheadings
• Declare exact dimensions and weight to calculate duties accurately and avoid undervaluation penalties

Compressed Cork Insulation Sheets
These are rigid sheets made from compressed agglomerated cork particles, often used for thermal and acoustic insulation in walls and roofs. They fall under HTS 4504.10.20.00 as they are specifically classified as insulation products from compressed cork, coated or not. The material's natural properties provide excellent sound absorption and heat resistance.
Uncoated Compressed Cork Acoustic Insulation Boards
Dense boards manufactured from compressed cork granules for superior soundproofing in studios and theaters. They qualify for HTS 4504.10.20.00 as uncoated insulation made from agglomerated compressed cork. Their porous structure effectively dampens noise vibrations.
Compressed Cork Roof Insulation Strips
Narrow strips of compressed agglomerated cork designed for under-roof thermal insulation in construction. Falls under HTS 4504.10.20.00 as strip-form insulation from compressed cork, suitable for both coated and uncoated variants. Provides natural fire resistance and sustainability.
Fire-Resistant Coated Cork Insulation Disks
Solid cylindrical disks of compressed cork with intumescent coating for pipe insulation and fire barriers. Classified in HTS 4504.10.20.00 as insulation disks explicitly covered under compressed cork provisions. The coating activates in high heat for added safety.
Compressed Cork Thermal Break Panels
Panels from compressed cork used as thermal breaks in steel structures to prevent heat bridging. HTS 4504.10.20.00 applies as coated or uncoated insulation plates of agglomerated compressed cork. Essential for energy-efficient building envelopes.
