9030.31.00.00 - Multimeters, without a recording device

This HTS classification, 9030.31.00.00, specifically covers multimeters that are designed for measuring electrical quantities such as voltage, current, and resistance, but crucially, **without any built-in recording device**. These instruments are characterized by their ability to perform multiple measurement functions within a single unit, distinguishing them from single-function meters. The primary purpose is immediate on-screen display of measured electrical parameters for diagnostic, testing, or calibration purposes in electrical and electronic systems.

It is important to differentiate this category from its sibling entries. HTS code 9030.32.00.00, for example, covers multimeters that *do* include a recording device, indicating a significant functional difference. Similarly, categories like 9030.33 and 9030.39.01.00 encompass other instruments for measuring electrical quantities, but their specific inclusions or exclusions (like the presence or absence of a recording function) set them apart from the precise scope of 9030.31.00.00.

As a leaf node within the HTS, 9030.31.00.00 represents a definitive classification for these specific types of multimeters. Practical classification relies on the physical absence of data logging or storage capabilities. This means devices that require external connections to record data, or entirely lack the ability to store measured values, would fall under this heading, provided they meet the general criteria for multimeters used for measuring electrical quantities and are not designed for semiconductor wafer or device measurements.
