N356022 · 2025-12-12 — The tariff classification of gluten detection capsules and detection systems from China
, you requested a tariff classification ruling. The samples were received, examined, and disposed of. The first item under consideration is described as the single-use Gluten Detection Capsule. Each Capsule contains a lateral flow antibody test strip with two proprietary antibodies designed to detect gluten, a proprietary extraction buffer, and spindle-shaped features. The cap of the Capsule has teeth-shaped features. When the cap is screwed down, it helps to grind the food and release the extraction buffer. The Capsule must be inserted into the Sensor to complete the gluten detection test.…
N350072 · 2025-07-01 — The tariff classification of blood monitoring meters from South Korea
, you requested a tariff classification ruling. Descriptive literature was provided for our review. The first three items under consideration are described as high-accuracy prothrombin time/international normalized ratio (PT/INR) test meters (model numbers PT2 PT/INR Monitoring Meter PST, PT2 PT/INR Monitoring Meter Pro, and PT3 PT/INR Monitoring Meter PST). The devices are primarily designed for home and laboratory use, allowing patients with chronic cardiovascular or thromboembolic conditions requiring anticoagulant therapy to monitor their PT/INR levels. The PT/INR meters are available by…
N348517 · 2025-05-16 — The tariff classification of blood testing meter systems from Malaysia
Descriptive literature was provided for our review. The items under consideration are the AlCNow+ and the AlCNow Self Check HbAlc blood testing meter systems, which are systems intended to quantitatively measure the percentage of glycated hemoglobin in fresh capillary blood samples from the fingertip. The primary difference between the AlCNow+ and the AlCNow Self Check is that the AlCNow+ is typically used in professional settings and has a larger number of test cartridges included in the kit (quantity of ten or twenty depending on the set) versus the AlCNow Self Check (quantity of four). The…
N341992 · 2024-09-10 — The tariff classification of a bead reader from China
Descriptive literature was provided for our review. The item under consideration is described as the SimoaOne Bead Reader, which is an instrument that utilizes flow cytometry-based principles to measure biomarkers. The consumables used with this reader are ultra sensitivity immunoassay kits. Using the kits, the user tags the particles being measured with fluorescence markers. On the instrument, the particles on the beads tagged with fluorescence are then pushed through a flow cell to be individually activated by lasers. The reader then counts “on” and “off” beads (“on” beads means a particle…
N340863 · 2024-07-15 — The tariff classification of the Xenium Analyzer from Singapore
The item under consideration is described as the Xenium Analyzer, which is a high-resolution, imaging-based spatial profiling technology that allows for simultaneous expression analysis of ribonucleic acid (RNA) targets within the same tissue section. The assay can identify the location of target transcripts within the tissue, providing a single cell resolution map of expression patterns of all genes that are included in the selected probe panel. Researchers can choose between off-the-shelf panels of genes designed to identify cell types and interrogate specific phenotypes, add on 50-gene or…
