, Ltd., you requested a tariff classification ruling. Descriptive literature was provided for our review. The item under consideration is described as an LCR Checker (model number SD-YALCR-A02), which is an inspection device that attaches to a chip mounter in the surface mount technology (SMT) manufacturing process. The device measures the electrical characteristics of surface mount passive components, including inductors (“L”), capacitors (“C”), and resistors (“R”), in real time. The device operates on power supplied from the mounter and automatically measures component values through its…
N354205 · 2025-10-08 — The tariff classification of an electrical measurement device from India
Descriptive literature was provided for our review. The item under consideration is described as the Emporia Vue3 Energy Monitor, which is a whole-home energy monitoring system that installs in a home’s electrical panel to track real-time energy usage, identify high-consumption appliances, and automate energy management via the Emporia Energy app. It uses clamp-on sensors to measure total energy and can monitor up to 16 individual circuits, providing data for solar monitoring, net metering, and reducing electricity costs. The device provides real-time current, voltage, and power measurements…
N331279 · 2023-03-21 — The tariff classification of voltage transducers from Germany
The four items under consideration are described as voltage transducers, which are devices designed to measure voltage in electrical systems. The voltage transducers perform a measuring function by recognizing the input voltage seen and converting it, proportionately, to a standard output signal across an isolation barrier based on inductive coupling. The transducers measure voltage anywhere from a small mV level, up to 4800 V, both AC and DC. The units of measure provided by the transducers are considered “standard” unit ranges recognized by industrial control systems and are provided to the…
N320622 · 2021-08-03 — The tariff classification of a storage box and battery tester from China.
Item code WIC 387131, Battery Box, is a double-sided battery storage box made of molded plastic. The box includes a removable battery tester and holds various sized batteries, which are not included. The battery tester measures the battery power and displays Good, Low, or Replace. In your request, you suggested that the battery box and battery tester should be classified under subheading 4202.99.9000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “other containers and cases, other, other, other.” The article has two components and neither of them imparts the…
