Last updated: April 2026 dataOccupying the mid-weight band between 150 and 225 g/m², this uncoated NES kraft grade bridges the gap between flexible wrapping paper and heavier packaging board — a range commonly used for grocery bags, industrial wrapping, and single-face corrugated liner applications. The grammage window is narrow enough that mill test certificates showing exact basis weight are essential to avoid misclassification into the lighter (64146) or heavier (64148) adjacent headings. Buyers converting this material into finished packaging should verify that the declared weight reflects the actual delivered product, as moisture content can affect measured grammage.

Importers should obtain ISO 536-compliant basis-weight test reports from the producing mill, measured under standardized conditioning (temperature and humidity). Because moisture affects measured grammage, test conditions matter — a product near either boundary should be tested under the same conditions referenced in the tariff schedule to avoid classification disputes at the border.
This mid-weight band is widely used for grocery sacks, retail shopping bags, heavy-duty wrapping, and as liner material in corrugated board construction. It offers a balance of stiffness and foldability that lighter grades lack, without the rigidity of heavier paperboard grades above 225 g/m².
