Heading 2524

Asbestos

7 declarable lines

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.

How to choose the right subheading

Identify the asbestos variety: crocidolite is named separately, and amosite has its own line under 2524.90.
If the fiber is chrysotile, determine the form: crude, milled fiber of group 3 grades, milled fiber of group 4 and 5 grades, or other.
For milled chrysotile, confirm the grade group (3 versus 4 and 5) because the grading decides between two lines.
If the material is not crocidolite, amosite or chrysotile, classify it as other asbestos under 2524.90.
Confirm the goods are raw fiber or milled fiber, not a finished article such as a sheet, gasket or lining.
