3215.90.10.00 - Drawing ink

This HTS category, 3215.90.10.00, specifically covers drawing ink. Drawing inks are a type of ink formulated and intended for use in artistic and technical drawing applications, such as sketching, drafting, calligraphy, and illustration. They are designed to produce lines with specific characteristics regarding flow, opacity, and permanence.

This classification distinguishes itself from its sibling, 3215.90.50.00, which is designated for "Other" inks not specifically enumerated elsewhere. While this category is for drawing ink, the "Other" category would encompass a broader range of inks that do not fit into the more specific classifications within heading 3215, such as certain specialized industrial inks or proprietary formulations not primarily intended for writing or drawing.

As a leaf node, this classification does not have further subcategories. Therefore, the primary focus for classification under 3215.90.10.00 is to confirm that the ink's intended use and physical properties align with those of typical drawing inks, as opposed to general-purpose writing inks or printing inks. Classification decisions should be guided by the ink's formulation and its primary application in drawing and artistic endeavors.
