3215.11.90.30 - Gravure

This HTS classification covers black printing inks specifically formulated for gravure printing processes. Gravure printing is a high-volume, high-quality printing method where the image is etched into a cylinder, and ink is transferred from these engraved cells to the substrate. The inks classified here are designed to have specific viscosity, drying properties, and pigment characteristics suitable for this intaglio-based printing technique.

Distinguishing this category from its siblings, gravure inks differ from flexographic inks (3215.11.90.20) which are generally lower viscosity and suitable for raised printing plates. Letterpress inks (3215.11.90.40) are also typically higher viscosity, designed for relief printing. Offset lithographic inks (3215.11.90.50) are formulated to work with a water/ink balance on a plate. While all are black printing inks, the gravure classification is dictated by the unique requirements of the gravure printing method.

As this classification is a leaf node, there are no further subdivisions within the HTS. This means that any black ink intended for gravure printing, regardless of its specific formulation for different substrates (such as paper, plastic, or metal) or color additives beyond black pigment, will fall under this code, provided it meets the general criteria for printing inks and the specific requirements of gravure application.
