9609.20.40.00 - Over 1.5 mm in maximum cross-sectional dimension

This HTS category, 9609.20.40.00, specifically covers pencil leads that exceed 1.5 millimeters in their maximum cross-sectional dimension. These leads are intended for use in pencils or mechanical pencils and are distinguished from other pencil leads by this physical characteristic. The material composition, whether graphite, colored pigments, or a combination thereof, is not the primary determinant for classification within this specific subheading, provided they are designed as pencil leads.

Crucially, this subheading differentiates itself from its sibling, 9609.20.20.00, based solely on the diameter. While 9609.20.20.00 pertains to pencil leads with a maximum cross-sectional dimension *not over* 1.5 mm (i.e., 1.5 mm or less), this category applies to leads with a diameter *over* 1.5 mm. This distinction is vital for accurate tariff application and revenue collection.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Therefore, classification under 9609.20.40.00 is definitive for pencil leads meeting the specified diameter criterion. Examples of goods that would fall under this subheading include thicker leads for carpenter's pencils, artists' sketching leads, or leads for certain industrial marking pencils where a broader line is required.
