4908.10.00.00 - Transfers (decalcomanias), vitrifiable

HTS code 4908.10.00.00 specifically covers vitrifiable transfers, commonly known as decals intended for application to ceramic or glass surfaces and subsequent firing in a kiln. These transfers typically consist of a printed design on a soluble or release paper, which, after application, becomes permanently fused to the substrate upon firing. The key characteristic defining this subcategory is the "vitrifiable" nature, indicating their specialized use in creating durable, decorative finishes on materials like pottery, tiles, and glassware, where the design integrates with the surface through heat.

This category is distinct from its sibling, 4908.90.00.00, which encompasses all other types of transfers not specifically classified as vitrifiable. For instance, 4908.90 would include transfers for textiles, temporary tattoos, or other non-ceramic/glass applications that do not undergo a vitrification process. The primary differentiator lies in the intended application and the material transformation that occurs during firing for vitrifiable transfers.

As this is a leaf node within the HTS, there are no further subcategories under 4908.10.00.00. Therefore, classification within this code is determined by the explicit characteristic of being a vitrifiable transfer. Importers and exporters should confirm that the intended use and manufacturing process of the transfers align with the definition of vitrification to ensure accurate classification.
