9902.17.29 - Oscilloscopes and oscillographs, having a bandwidth range of 20 GHz to 90 GHz and a sampling rate range of 50 megabytes per second (50 Mbps) to 80 gigabytes per second (80 Gbps), each with 1 to 16 measurement channels, internal hard drive, 1 to 4 interchangeable measurement modules and a color touch screen measuring over 25 cm but not over 28 cm (provided for in subheading 9030.20.10), the foregoing other than hand-held

This HTS classification, 9902.17.29, pertains to a specific type of advanced oscilloscope or oscillograph. These instruments are characterized by their high bandwidth (20 GHz to 90 GHz) and rapid sampling rates (50 Mbps to 80 Gbps), making them suitable for detailed signal analysis in demanding applications. Further defining criteria include the presence of 1 to 16 measurement channels, an integrated internal hard drive for data storage, and the capability to accommodate 1 to 4 interchangeable measurement modules. A key visual and functional identifier is the color touch screen, measuring between 25 cm and 28 cm, and importantly, these devices are explicitly excluded if they are hand-held.

This category is part of Chapter 99, which houses temporary legislation and special classification provisions, often related to trade agreements or specific import restrictions. It is crucial to distinguish this entry from the general classification of oscilloscopes and oscillographs found elsewhere in the HTS, such as subheading 9030.20.10, which is referenced as the base classification. While the underlying technology of measuring electrical phenomena is shared, this Chapter 99 heading applies only to those instruments meeting the precise technical specifications outlined above, suggesting a potential temporary preferential tariff or a specific regulatory control.

As a leaf node, HTS 9902.17.29 does not have further subcategories. Therefore, the classification is determined solely by meeting all the detailed technical and physical characteristics outlined in the description. The emphasis is on the specific performance parameters (bandwidth, sampling rate), modularity, storage, screen size, and the exclusion of hand-held versions, ensuring a precise application of this special provision.
