9902.14.87 - Liquid-filled glass bulbs designed for use in sprinkler systems and other release devices (provided for in subheading 7020.00.60)

This HTS category, 9902.14.87, specifically covers liquid-filled glass bulbs intended for use in fire suppression systems, such as automatic sprinklers, and other release mechanisms. These bulbs are engineered to fracture or break at a predetermined temperature, thereby activating the release device. While made of glass and containing a liquid, their critical defining characteristic is their specialized application within safety and release systems, distinguishing them from general glass articles.

As this is a leaf node within Chapter 99, there are no further subcategories. The classification of these specialized bulbs is ultimately tied to their functional purpose as components of release devices. It is important to note that while the description references subheading 7020.00.60, this HTS 9902 code represents a temporary or specific import provision. Classification decisions should always confirm compliance with the underlying primary tariff provision and any applicable notes or restrictions associated with Chapter 99.
