Overview

This HTS category, 2524.90.00.40, specifically covers milled asbestos fibers designated as "group 3 grades." These fibers are characterized by their fineness and suitability for direct use in spinning processes or equivalent industrial applications where fine, staple fibers are required. The primary distinction lies in the grading of the milled fibers, which dictates their application and handling.

Distinguishing this category from its siblings, 2524.90.00.30 refers to the raw, unprocessed form of asbestos (crudes). Category 2524.90.00.45 encompasses milled fibers of a coarser texture, categorized as group 4 and 5 grades, intended for different industrial uses. The remaining sibling, 2524.90.00.55, serves as a residual category for any other asbestos-related products not falling into the preceding specific subheadings.

As this is a leaf node within the HTS database, there are no further subcategories. Therefore, classification under 2524.90.00.40 relies on accurately identifying the milled asbestos fibers as belonging to the "group 3 grades" based on their physical properties and intended use in spinning or similar fine fiber applications. Importers and exporters should consult available technical documentation or expert analysis to confirm the grading of their milled asbestos fibers to ensure correct classification.
