8539.21.40 - Other

This HTS category, 8539.21.40, encompasses "Other" tungsten halogen filament lamps that do not fall under the specific voltage classification of its sibling category. It serves as a residual category for tungsten halogen lamps, meaning it captures those not explicitly designated for voltages not exceeding 100 V, as per 8539.21.20. Therefore, lamps in this classification are typically intended for standard household or industrial voltage ranges exceeding 100 V.

The classification is further refined by subcategories based on the electrical power consumption of the lamp. This distinction is crucial for tariff purposes, as different power ratings may be subject to varying duty rates or trade regulations. Understanding these power specifications is essential for accurate declaration and compliance.

The subcategories within 8539.21.40 are: 8539.21.40.40, covering tungsten halogen lamps with a power rating less than 500 W, and 8539.21.40.80, which includes those with a power rating of 500 W or more. These subdivisions allow for granular tracking and differentiated trade statistics based on the lamp's operational capacity.
