9902.17.32 - True RMS (root mean square) multimeters, without recording device, hand-held, each having either 3-1/2, 4 or 4-1/2 digits of measurement accuracy and either a liquid crystal display (LCD) or organic light emitting diode (OLED) display screen, designed to provide one or more of the following measurements: DCV, ACV, DCI, ACI, 2 and/or 4 wire resistance, frequency, continuity, diode test, capacitance, temperature, dB, switch counter, harmonic ratio, pulse width, delay cycle and/or 4 to 20 mA percent scale (provided for in subheading 9030.31.00).

This HTS classification, 9902.17.32, pertains to specific types of hand-held multimeters that are designed for True RMS (root mean square) measurements. These devices are characterized by their measurement accuracy, indicated by 3-1/2, 4, or 4-1/2 digits, and their display type, which can be either a liquid crystal display (LCD) or an organic light emitting diode (OLED). The functionality of these multimeters is further defined by their capability to perform a comprehensive range of electrical measurements, including DC voltage, AC voltage, DC current, AC current, various resistance measurements (2 and/or 4 wire), frequency, continuity, diode testing, capacitance, temperature, decibels (dB), switch counter operations, harmonic ratio calculations, pulse width determination, delay cycle analysis, and a 4 to 20 mA percent scale. Crucially, these multimeters do not include a recording device.

It is important to distinguish this classification from other potential classifications within Chapter 99 or other HTS chapters. While Chapter 99 generally covers temporary legislation and trade agreement modifications, this specific subheading carves out a niche for these particular instruments. The detailed functional and physical specifications listed in the description are key to differentiating these multimeters from general-purpose electrical testing equipment or those with recording capabilities, which would fall under different HTS codes. The provision for these multimeters under subheading 9030.31.00 indicates their primary function as measuring instruments.

As a leaf node, HTS 9902.17.32 does not have further subdivisions. Therefore, understanding the scope of this classification relies entirely on the detailed description provided. Practical application of this classification will involve verifying that the imported multimeters meet all the enumerated criteria regarding their measurement accuracy, display technology, and specific measurement functions, while also confirming the absence of any recording device. This ensures accurate customs declarations and proper duty assessment under the prevailing trade provisions.
