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.

4504.90.00.00Same rate: 35%

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.

4411.94.00Same rate: 35%

If fiberboard binders dominate over cork

Medium density fiberboard (MDF) with minor cork is classified under wood-based panels in Chapter 44.

3921.90Lower: 14.8% vs 35%

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
