Gravure cylinders prepared for printing are classified under heading 844250 (specifically 8442509000 for prepared cylinders), not under the press heading 844317. When a press is imported with a set of cylinders, CBP generally expects the cylinders to be separately identified and valued on the commercial invoice so each component can be classified correctly. Bundling cylinders into the press price without itemization can create classification and valuation issues at entry.

Gravure presses are used on a wide range of substrates — plastic films, aluminum foil, paper, and paperboard — particularly in flexible packaging and decorative printing. The substrate type does not affect the classification of the press itself; all gravure printing machinery classifies under 8443170000 regardless of the intended substrate. Substrate type may, however, influence the technical specifications buyers should verify when sourcing equipment.
