9902.15.70 - Flexographic printing machinery, having continuous roll feed, designed for printing on paperboard (whether or not such paperboard is coated), having a printing speed of 599 m/minute or more but not more than 801 m/minute and a print width of 106 cm or more but not more than 178 cm (provided for in subheading 8443.16.00)

This HTS category, 9902.15.70, specifically addresses a specialized type of flexographic printing machinery. These machines are characterized by their continuous roll feed mechanism and are engineered for printing on paperboard, regardless of whether the paperboard is coated or uncoated. Crucially, the classification is contingent upon precise operational parameters: a printing speed ranging from 599 to 801 meters per minute and a print width spanning from 106 to 178 centimeters. This category falls under Chapter 99, which pertains to temporary legislation and trade agreement modifications, indicating its special or provisional nature rather than being a permanent tariff classification under the main chapters of the HTS.

While the broader HTS system includes numerous categories for various types of machinery, this particular subheading distinguishes itself by its highly specific technical criteria. Unlike general printing presses or other types of flexographic machines that might not meet the defined speed or width specifications, or are designed for different substrates, this category isolates high-speed, high-volume paperboard printing equipment. Its placement within Section XXII, relating to Special Classification Provisions and Temporary Legislation, further sets it apart from the standard classification of machinery found in Chapters 84 and 85. The parenthetical reference to subheading 8443.16.00 indicates that this temporary classification likely modifies or provides special treatment for goods that would otherwise fall under that primary machinery heading.

As this HTS code is a leaf node, there are no further subcategories to explore within this specific classification. This means that any machinery meeting all the detailed physical and performance criteria described will be directly classified under 9902.15.70. The classification relies entirely on the precise match between the machine's specifications (roll feed, paperboard substrate, speed range, and print width range) and the description provided. For practical purposes, importers and exporters must verify that their product precisely aligns with these parameters to ensure correct customs declaration under this temporary provision.
