Importers of Parts for Paper-Making and Paper-Finishing Machinery paid $2.1M in duties in July 2026 — an effective duty rate of 7.7% on $26.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataItaly leads US imports of parts for paper-making and finishing machinery, with Finland, Canada, and Germany also prominent — a supplier base that mirrors the geographic concentration of paper machine OEMs and their global aftermarket operations. The heading divides cleanly into parts for paper-making machinery (8439991000) and parts for finishing machinery (8439995000), and correct assignment between the two lines depends on identifying the parent machine's function rather than the part's own characteristics. High-value components such as press rolls, forming fabrics, and coating heads drive significant recurring import activity as mills maintain and upgrade existing installations.

Classification follows the principal machine function the part serves. If the roll is designed for and primarily used in the paper-forming section, 8439991000 applies; if it serves a finishing function (e.g., calendering), 8439995000 is appropriate. When a part is genuinely interchangeable across both sections, importers should seek a CBP binding ruling to establish a defensible classification position.
Both lines fall within the same heading and are subject to the same MFN duty structure, but they are tracked separately for statistical and classification purposes. Correct assignment matters for CBP compliance and for accurately reporting trade data, even when the duty rate is identical. Misclassification between the two lines can trigger CBP inquiries during post-entry review.
