3215.11.90.60 - Other

This HTS category, 3215.11.90.60, encompasses printing inks that are black in color but do not fall under the more specific subheadings for flexographic, gravure, letterpress, or offset lithographic printing processes. This residual classification is intended for black printing inks used in other printing applications or where the specific printing method is not the primary defining characteristic for classification purposes, or if the ink has characteristics not neatly fitting into the other defined categories.

The distinction between this category and its siblings (3215.11.90.20 through 3215.11.90.50) lies in the absence of a defined printing method. While the sibling categories explicitly identify inks designed for particular printing technologies like flexography or offset lithography, this "Other" category serves as a catch-all for black printing inks that do not meet the criteria for those specialized uses. The classification relies on the absence of a specific printing method qualifier.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, classification within 3215.11.90.60 is based on the exclusion from the more precisely defined sibling categories. Importers and exporters should carefully review the specific application and formulation of their black printing inks to ensure they are not better classified under the more granular subheadings before assigning them to this residual "Other" category.
