Parts for Pulping and Papermaking or Finishing Machinery

Press rolls and forming fabrics designed specifically for use in papermaking machines are generally classified as parts of papermaking machinery when they are identifiable as dedicated components of those machines. However, if the item is a general-purpose roll or fabric not exclusively used in papermaking, it may be classified by its own material composition. OEM part numbers and machine-specific design documentation support the parts classification.

Parts for machines that form, press, dry, or finish paper or paperboard in the primary manufacturing process belong here. Parts for machines that subsequently cut, bag, box, or mold the finished paper into secondary products fall under the separate parts heading for paper-making-up machinery. The parent machine's function — primary production versus converting — determines which parts heading applies.
