9902.17.36 - Electromagnetic interference (EMI) receivers, each having a frequency band range from 3 Hz to 44 GHz, conforming to LXI (Local area network eXtension for Instruments) standard, with two radio frequency (RF) inputs and with a color display screen with a display diagonal exceeding 20 cm but not exceeding 23 cm (provided for in subheading 9030.84.00).

This classification pertains to specialized Electromagnetic Interference (EMI) receivers, designed for advanced testing and measurement applications. These instruments are characterized by their broad frequency band range, spanning from 3 Hz to 44 GHz, and their adherence to the LXI (Local area network eXtension for Instruments) standard, facilitating networked operation and integration. Key physical attributes include two radio frequency (RF) inputs for signal reception and a color display screen with a diagonal measurement between 20 cm and 23 cm, crucial for data visualization and analysis. The provision for these receivers is found under subheading 9030.84.00, indicating their primary function in measuring or verifying electrical quantities.

Given that this node resides within Chapter 99, which addresses temporary legislation and special provisions, its distinction from other sibling categories (such as live animals or basic commodities listed under Chapter 1 through 98) is fundamental. Chapter 99 entries are highly specific and often reflect unique trade policies, temporary duty rates, or quantitative restrictions. Therefore, the EMI receivers classified here are differentiated not by inherent material composition or general product category, but by their specific technological specifications and their inclusion under temporary trade measures, making direct comparison with broad product chapters impractical.

As this classification represents a leaf node, there are no further subcategories to explore. The description provided is definitive for the scope of goods covered. Classification under this HTS code requires that an EMI receiver meet all the specified technical criteria, including its frequency range, LXI compliance, number of RF inputs, and precise display screen dimensions. Any deviation from these parameters would necessitate re-evaluation under a different HTS classification.
