2524.90.00.60 - Other

HTS Code 2524.90.00.60, described as "Other," encompasses all forms of asbestos not specifically enumerated under preceding subheadings within the 2524 chapter. This includes any naturally occurring mineral fiber that falls under the broader classification of asbestos but does not fit the distinct categories of amosite or chrysotile asbestos. The classification hinges on the absence of specific identifying characteristics that would place it within more granular subheadings.

This category serves as a residual grouping for asbestos types that are not amosite (brown asbestos) or chrysotile (white asbestos). While amosite is characterized by its straight, flat fibers and chrysotile by its curly, flexible fibers, the "Other" category captures any remaining asbestos mineralogical classifications. The primary distinguishing factor for inclusion here is that the asbestos material does not conform to the specific chemical or physical properties defining amosite or chrysotile.

As this is a leaf node, there are no further subcategories. Therefore, the classification relies on identifying materials as asbestos but excluding them from the more specific sibling categories of amosite and chrysotile. For practical purposes, this would include asbestos varieties such as crocidolite (blue asbestos) and anthophyllite, provided they meet the general definition of asbestos and are not classified elsewhere.
