SITCSection 6
U.S. imports of uncoated paper & paperboard (40–150 g/m², low mechanical fiber) in rolls or sheets (SITC 64126) totaled $109.3M in April 2026, traded with 40 countries.
Importers of Uncoated Paper & Paperboard (40–150 g/m², Low Mechanical Fiber) in Rolls or Sheets paid $5.4M in duties in April 2026 — an effective duty rate of 10% on $53.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Uncoated Paper & Paperboard (40–150 g/m², Low Mechanical Fiber) in Rolls or Sheets imports of $109.3M in April 2026 ran 11% above the year-to-date monthly average of $98.3M.
Last updated: April 2026 dataDefined by a basis weight band of 40 to 150 g/m² and a mechanical-fiber content not exceeding 10% by weight, this category captures the bulk of chemical-pulp printing and writing papers used in commercial offset, digital, and business-forms applications. The low mechanical-fiber threshold is the critical specification: papers exceeding 10% mechanical fiber shift to a different SITC heading with potentially different duty treatment, making pulp-composition certificates from the mill an essential import document. Buyers sourcing large-volume rolls for converting operations should confirm basis weight and fiber-source data on each shipment's mill certificate to avoid reclassification risk.

Papers with 10% or less mechanical fiber by weight fall under SITC 64126, while those exceeding that threshold fall under 64129 — and the two headings may carry different duty rates and trade-remedy exposure. Because mechanical fiber content is not visually apparent, importers must rely on mill test certificates or independent laboratory analysis to confirm compliance with the threshold at the time of entry.
Mill certificates specifying the nominal g/m² weight, fiber composition (chemical vs. mechanical pulp percentages), and roll dimensions are the primary supporting documents. For large-volume shipments, some importers also commission third-party laboratory testing to verify basis weight and fiber content, particularly when sourcing from mills with limited audit history.
