N359718 · 2026-03-26 — The tariff classification of a Balanced Detector from Germany
Descriptive literature was provided for our review. The item under consideration is described as a Balanced Detector (model number BD-HQE-775), which is a high-quantum efficiency (HQE) balanced photodetector designed for operation at a wavelength of 400 nm to 1030 nm. Balanced Detectors are devices that utilize two precisely matched photodiodes and a differential amplifier to subtract two optical input signals from each other. This subtraction process effectively cancels out common-mode noise (like laser intensity fluctuations) present in both inputs, significantly improving the…
N355538 · 2025-11-25 — The tariff classification of a continuous glucose monitor from China
Descriptive literature was provided for our review. The item under consideration is described as the KOS Argus Non-Invasive Continuous Glucose Monitor (CGM), which is a prescription, non-invasive device used to continuously measure, record, analyze, and display real-time glucose values using infrared, red, and green sensors. The tri-wavelength optical system interrogates different tissue compartments. The green-light spectrum penetrates the epidermis, capturing superficial capillary bed dynamics. The red-light spectrum reaches the dermis layer, monitoring intermediate vascular networks.…
N352518 · 2025-08-29 — The tariff classification of spectroscopy scanner from China
Descriptive literature was provided for our review. The item under consideration is described as the Prysm iO, which is a portable, rechargeable scanner that uses reflectance spectroscopy technology to measure carotenoid levels in the skin. It incorporates Spectral Rai Technology, capturing over 100,000 hyperspectral absorption measurements per scan (6,000 plus per second) to assess light absorption in the skin. An artificial intelligence (AI)-driven algorithm converts these measurements into a “Prysm Score,” factoring out biological markers that could otherwise interfere with accuracy. In…
N351195 · 2025-07-21 — The tariff classification of Balanced Detectors from Germany
Descriptive literature was provided for our review. The items under consideration are described as Balanced Detectors (model numbers BD-HQE-1550 and BD-HQE-1064), which are high-quantum efficiency (HQE) balanced photodetectors designed for operation at a wavelength of 1550 nanometers (nm) and 1064 nm respectively. Balanced Detectors are devices that utilize two precisely matched photodiodes and a differential amplifier to subtract two optical input signals from each other. This subtraction process effectively cancels out common-mode noise (like laser intensity fluctuations) present in both…
N342063 · 2024-08-16 — The tariff classification of the IDEXX InVue Dx Cellular Analyzer from the United States
The item under consideration is described as the IDEXX InVue Dx Cellular Analyzer, which is a device that performs pathologist-level cellular analysis and blood morphology testing for canines and felines. Instead of slides, the instrument uses disposable consumables to dilute and stain samples and present them to a digital optics system analysis. The InVue Dx takes 2,000-3,000 images per run with an effective 7x magnification for each image using a 5-megapixel monochrome sensor. The sample images captured are analyzed for element identification and classification to provide diagnostic…
