Vitrifiable transfers (490810) are designed to be fused to glass, porcelain, or enamel surfaces through kiln firing, making them permanent and heat-resistant. Non-vitrifiable transfers (490890) adhere through pressure, water activation, or adhesive without high-temperature firing and are used on plastics, metals, and paper. The intended application method and substrate determine which subheading applies.

No. Heading 4908 explicitly excludes toy transfers; those are classified under the toys chapter. Only commercial, industrial, and decorative decalcomanias intended for non-toy applications fall here.
