9902.08.87 - Organic luminescent pigments and dyes for security applications (provided for in subheading 3204.90.00), the foregoing excluding daylight fluorescent pigments and dyes and excluding the dyestuff bearing the CAS No. 6359-10-0

This HTS category, 9902.08.87, specifically addresses organic luminescent pigments and dyes designated for security applications. These specialized materials are intended to emit light when exposed to certain wavelengths, making them suitable for anti-counterfeiting measures, secure markings, and other applications where visual authentication or detection is critical. The inclusion in Chapter 99 signifies that these are subject to temporary legislation or specific import restrictions, as opposed to permanent classification under other chapters.

It is crucial to distinguish this category from general pigment and dye classifications found elsewhere in the HTS. While the base materials might otherwise fall under Chapter 32, the defining characteristic here is their intended *use in security applications* and their *luminescent properties*. Furthermore, this classification explicitly excludes daylight fluorescent pigments and dyes, which have a different luminescence mechanism and are typically used for high visibility rather than covert security features. The exclusion of the dyestuff with CAS No. 6359-10-0 provides a further precise delineation.

As this is a leaf node within the HTS database, there are no further subcategories for this specific code. Classification within 9902.08.87 is determined by meeting all the criteria outlined in its description, particularly the luminescent nature, intended security application, and the specific exclusions mentioned. Importers must ensure that the goods precisely match these specifications to be correctly classified under this provision.
