9902.17.37 - Multifunction devices for calibrating electrical safety testers, each incorporating signal generator and multimeter, with a recording device (provided for in subheading 9030.84.00)

This HTS code, 9902.17.37, specifically designates multifunction devices intended for the calibration of electrical safety testers. These sophisticated instruments integrate essential functionalities, including a signal generator and a multimeter, crucial for testing and verifying the performance of electrical safety equipment. Furthermore, these devices are equipped with a recording capability, which is a key distinguishing feature.

While this classification exists within Chapter 99, a section dedicated to temporary legislation and trade agreement modifications, its specific nature sets it apart from other temporary or specialized classifications. Its primary differentiator lies in the precise technical function and composite nature of the equipment it covers. Unlike broad categories of general electrical testing equipment found elsewhere in the HTS, 9902.17.37 is narrowly focused on calibration devices with integrated signal generation, measurement, and recording functions.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification is highly specific. Classification under 9902.17.37 hinges on the complete presence of all described components and their integrated purpose: serving as a multifunction calibration device for electrical safety testers, inclusive of signal generation, multimeter functionality, and recording capabilities. The reference to subheading 9030.84.00 indicates that the underlying fundamental nature of these devices aligns with instruments for measuring or checking electrical quantities, but their specialized application and feature set place them under this specific temporary provision.
