N350068 · 2025-06-24 — The tariff classification of a particulate matter sensor from China
The item under consideration is the Sensirion SPS30 particulate matter sensor, which is a device that utilizes a laser scattering method to measure the concentration of particles in the air. It works by directing a laser beam through a controlled airflow containing airborne particles. The particles scatter the laser light, and the sensor detects the scattered light using a photodiode. The intensity and pattern of the scattered light are then analyzed to determine the concentration of particles. The sensor's internal algorithms process the electrical signal to determine the concentration of…
H341677 · 2025-02-14 — Application for Further Review of Protest No 280924111068; Applicability of Section 301 trade remedies of breathalyzers from China
This is our decision regarding an Application for Further Review (AFR) of Protest No. 2809241110681 filed by counsel on behalf of KHN Solutions LLC (dba BACtrack) (Protestant). The Protest and AFR pertain to CBP’s determination on the applicability of the exclusion annotated under Chapter 99 U.S. Note 20(ttt)(ii)(34) under the Harmonized Tariff Schedule of the United States (HTSUS) to breathalyzers. Our decision is set forth below. No sample was provided. Within its AFR, the Protestant requested confidential treatment of entry and internal accounting information. Inasmuch as this request…
N340179 · 2024-05-29 — The tariff classification of air quality monitors from Italy
The first item under consideration is the Radoff Now air quality monitor, which is an indoor device used to measure atmospheric air temperature, humidity, pressure, fine particles, carbon dioxide, and volatile organic compounds, using an electric power source. The key measuring technologies are optical sensors with laser detection, non-dispersive infrared sensors, and metal oxide gas sensors. Measured data is wirelessly sent to a smartphone where the readings are displayed. The device measures 125mm by 125mm by 65mm and weighs 400g. It is made of ABS plastic and has anti-vibration rubber…
N335170 · 2023-09-28 — The tariff classification and country of origin of a hydrogen gas sensor printed circuit board assembly
The item under consideration is a completed printed circuit board assembly (PCBA) for a hydrogen gas sensor used to detect the levels of hydrogen in the air. When imported into the United States, the PCBA has a gas sensing element, which is incorporated onto a printed circuit board along with a microprocessor and various electronic components (resistors, capacitors, diodes, etc.). The remaining components, such as the plastic housing, plastic lid, and compression limiters, are assembled in the United States. Additional calibration and testing are also performed in the United States, however,…
N315116 · 2020-10-20 — The tariff classification of the Netatmo Carbon Monoxide Detector from China
The item under consideration is described as the Netatmo Carbon Monoxide Detector (item # NCO01), which consists of two plastic shells, a metal grid and an electronic board. The electronic board is composed of a carbon monoxide sensor, a buzzer, several microcontrollers and two soldered lithium batteries. In operation, the detector will analyze the parts per million (PPM) of carbon monoxide and sound an alarm if the levels surpass the EN 50291 standard. The PPM measurement is not displayed on the detector. Instead, the user utilizes a smart device to obtain the PPM readout. The device…
