About heading 2524
Asbestos
Heading 2524 covers asbestos, meaning the mineral fiber itself, not articles made from it. The heading splits first by variety: crocidolite (blue asbestos) gets its own line, amosite gets its own line, and remaining asbestos falls under 2524.90. Within that residual group, chrysotile is broken out by form: crudes, milled fibers of group 3 grades, milled fibers of group 4 and 5 grades, and other. Every line in the heading carries a general (MFN) rate of Free.
