3215.19.90 - Other

This HTS category, 3215.19.90, encompasses printing inks that do not fall into the more specific "Solid" subcategory. It covers liquid or paste printing inks designed for various printing processes, including offset, gravure, flexographic, and screen printing, where the ink is in a non-solid form at standard room temperature. The key defining characteristic is the ink's physical state, which is not solidified.

The distinction from its sibling category, "Solid" printing inks, is based on the physical form of the ink. Solid inks are typically supplied in a hardened state, often requiring melting or other processes to become usable for printing. This "Other" category, conversely, is for inks that are ready for application in a liquid or paste consistency.

Within this "Other" category, further subdivisions exist to refine the classification. For instance, a specific subcategory exists for inks used in newspaper printing (3215.19.90.10), indicating a specialized application. The subsequent "Other" subcategory within this level is intended for all remaining liquid or paste printing inks not specifically enumerated elsewhere, allowing for a comprehensive classification of diverse printing ink formulations.
