9902.16.93 - Ultraviolet lamps filled with deuterium gas, each with radio-frequency identification device and valued over $300 (provided for in subheading 8539.49.00)

This HTS category, 9902.16.93, specifically covers ultraviolet lamps filled with deuterium gas that are equipped with a radio-frequency identification (RFID) device and have a value exceeding $300. The parenthetical note "(provided for in subheading 8539.49.00)" indicates that these lamps, while classified under temporary provisions in Chapter 99, are fundamentally related to lighting apparatus and would otherwise fall under the general heading for electric lamps and lighting fittings. The deuterium gas filling is a key technical characteristic, distinguishing them from other types of UV lamps.

As a leaf node within Chapter 99, this specific subheading does not further subdivide the goods. Its distinctiveness from other sibling categories at the HTS Root Level (e.g., live animals in Chapter 01) is immediately apparent due to its placement within "Special Classification Provisions" and "Temporary Legislation." Its purpose is to apply specific temporary modifications or restrictions to the import of these specialized ultraviolet lamps, likely based on trade agreements or specific policy objectives, rather than a broad product category like those found in the earlier chapters of the HTS. The primary classification criteria are the presence of deuterium gas, the integrated RFID device, and the specified valuation threshold.
