Used and rebuilt presses are generally classifiable under the same heading as new equipment, but customs value is determined by the transaction value or an alternative valuation method reflecting the machine's actual condition. Importers of used presses should also be prepared to document the machine's age, prior use, and any refurbishment to support both valuation and admissibility, particularly if the press contains components subject to separate classification.

The defining characteristic is the paper-feed mechanism: reel-fed (web) presses draw paper continuously from a roll, while sheet-fed presses process individual cut sheets. This functional distinction is the primary classification criterion — press width, color units, and inline finishing capabilities are secondary descriptors that do not change the heading.
