N352482 · 2025-09-03 — The tariff classification of a heat sink assembly from China
Descriptive literature was provided for our review. The item under consideration is described as a heat sink assembly that is incorporated into the Visby Respiratory Health Point of Care Test and Visby Medical Sexual Health Test. In order to classify the heat sink assembly, we must first determine the classification of the main units that the assembly is a part of. The first tester is a disposable molecular diagnostic test that uses polymerase chain reaction (PCR), specifically RT-PCR (reverse transcriptase polymerase chain reaction), for qualitative detection and differentiation of nucleic…
N346345 · 2025-03-20 — The tariff classification of the Genotizer 20K Well Chip and the D_PCR Chip Case from South Korea
Descriptive literature and pictures were provided for our review. The first item under consideration is described as the Genotizer 20K Well Chip. The chip is made of plastic and is approximately 0.75 inches by 1.5 inches in size. It contains an array of over 20,000 microwells and is used with a Lab On An Array (LOAA) analyzer or an LOAA-M System for detection and quantification of nucleic acid targets. The LOAA is used for single runs, while the LOAA-M can be used for up to 16 runs. The chip also includes an Electrically Erasable Programmable Read-Only Memory (EEPROM) element for storing…
N330417 · 2023-02-09 — The tariff classification of a printed circuit board from Japan
The item under consideration is the ANGHVG printed circuit board (PCB), which is a device specifically designed for use with the cobas e 801 analyzer. The PCB contains a potentiostat, which applies the RE-WE voltage while maintaining the cell RE-WE voltage at a constant value. A relay protects the voltage from being applied when the software is not running. The PCB also reports the values of the cell CE-WE voltage and the measuring cell current to the EECL402/403 circuit board. The measuring cells are in the detection unit and are where the actual chemical reaction of patient blood and…
N317424 · 2021-02-19 — The tariff classification of printed circuit board assemblies from China
The items under consideration are described as printed circuit board assemblies (PCBAs), imported under part numbers 18-5026 (main PCBA), 18-5027 (LED PCBA), and 18-5018 (Sensor PCBA). The PCBAs are proprietary parts, specifically designed for use with the BiliDX diagnostic testing device. The BiliDX is a battery operated, optical measurement device used to quantify the level of Bilirubin in a sample of blood. In operation, a blood sample is placed directly onto a test strip and then placed in the BiliDX. The device shines a light through the blood sample and measures the resulting brightness…
N301983 · 2018-12-06 — The tariff classification of a Monitor Arm from Japan.
The item under consideration is identified as B44829 Monitor Arm. It is used with a line of clinical chemistry analysis instruments, models AU480, AU5800 and DxC 700 AU. Each of these instruments uses optical radiation and is powered by a connection to an electrical power main. The Monitor Arm is mounted to the chemistry analysis instruments and is used to hold a keyboard and monitor for the operator’s use. It is comprised of a mounting bracket and an articulated arm with two rotational hinges. The B44829 Monitor Arm is imported separately from the instruments when the existing arm needs to…
