Bleached Clay-Coated Kraft Paper & Paperboard, Over 95% Chemical Wood Fiber, Over 150 g/m² imports of $130K in July 2026 ran 29% above the year-to-date monthly average of $101K.
Last updated: July 2026 dataHeavier bleached clay-coated kraft paperboard — over 150 g/m² and derived from more than 95% chemical wood fiber — is the backbone of rigid consumer-goods packaging, including folding cartons for pharmaceuticals, cosmetics, and food products where structural integrity and printability must coexist. The weight threshold above 150 g/m² separates this heading from the lighter-weight equivalent under 481031 and is the primary classification decision point for importers of solid bleached sulfate (SBS) and folding boxboard grades. US lines include folding carton stock (4810321020), base stock for trays (4810321040), and a residual kraft paperboard line (4810321060), with separate treatment for unpunched cards (4810323000).

The split is at 150 g/m²: bleached clay-coated kraft paperboard with more than 95% chemical fiber at or below 150 g/m² classifies under 481031, while material exceeding 150 g/m² falls under 481032. Because basis weight can vary across a reel or lot, importers should use the certified average basis weight from the mill's quality certificate as the declared value, and consult a customs broker if the product is near the threshold.
Yes — cards not punched for punch-card machines and weighing over 150 g/m² have their own line (4810323000) within heading 481032, distinct from folding carton stock (4810321020) and other kraft paperboard lines. Index cards, file cards, and similar card stock products should be classified to this line rather than the general paperboard lines.
