Tar-Impregnated Insulation Facing Paper from Mexico
Tar-impregnated insulation facing paper is a kraft paper treated with bitumen or tar, supplied in rolls, and used as a vapor barrier on fiberglass insulation batts. The tar or bitumen coating provides moisture resistance, which is the essential character that classifies it under tariff item 4811.10.00 as tarred, bituminized or asphalted paper.
