8529.90.29.00 - Tuners

This HTS category, 8529.90.29.00, specifically classifies "Tuners" that are intended for use with television receivers, as further defined by Additional U.S. Note 9 to Chapter 85. These tuners are distinct from printed circuit assemblies, focusing on the electronic components responsible for selecting and amplifying radio frequency signals from broadcast or cable sources for display on a television. The primary function is to tune into specific channels, enabling the reception of television programming.

Within its immediate sibling categories, this classification distinguishes itself from other "Other" parts of television receivers not elsewhere specified. For example, sibling 8529.90.39.00 likely encompasses a broader range of non-printed circuit assembly parts for television receivers that do not meet the specific definition of a tuner. This category isolates the tuner function, ensuring accurate differentiation from general repair or component parts.

As this is a leaf node in the HTS database, there are no further subcategories. Therefore, the focus remains on the precise identification of the tuner as a standalone component or subassembly specifically designed for television receiver signal reception, excluding other functional components or more complex integrated circuit boards that might perform additional tasks. Classification into this sub-heading hinges on the singular purpose of tuning television channels.
