Overview
This HTS category, 9902.08.88, specifically covers phosphorescent pigments that are based on copper-doped zinc sulfide. The unique characteristic of this pigment is its ability to emit light after being exposed to a light source, a property attributed to the specific chemical composition involving zinc sulfide and copper doping. The CAS number 68611-70-1 serves as a precise identifier for this particular chemical substance. This classification is designated for temporary legislation and special provisions, indicating it is subject to specific trade agreement modifications or import restrictions.
Unlike the broad commodity categories represented by the sibling nodes such as live animals (Chapters 01) or other general chemical classifications (often found in Chapters 28-38), this entry is highly specialized. It isolates a specific type of pigment based on its chemical structure and luminescent properties. The reference to subheading 3206.42.00 within its description further clarifies its context by linking it to a broader HTS category for pigments and preparations, while this specific 99xx code applies temporary or special provisions.
As this node is a leaf node, there are no further subcategories. Classification under 9902.08.88 relies on the precise chemical identity and functionality of the phosphorescent pigment. Importers and exporters should ensure that the product's technical specifications align with the description of copper-doped zinc sulfide phosphorescent pigment and that any applicable temporary legislation or trade agreement conditions are met for proper customs clearance.
