U.S. exports of bleached uncoated kraft paperboard, 150–225 g/m², over 95% chemical wood fiber (HS 480442) totaled $3.5M in July 2026.
Bleached Uncoated Kraft Paperboard, 150–225 g/m², Over 95% Chemical Wood Fiber imports of $337K in July 2026 ran 65% below the year-to-date monthly average of $952K.
Last updated: July 2026 dataSolid bleached sulfate (SBS) and similar high-purity kraft paperboard in the 150–225 g/m² range — composed of more than 95% chemically processed wood fiber — is a primary substrate for premium folding cartons, milk and juice cartons, and food-service trays and cups. The fiber-purity threshold distinguishes this heading from 480449, which covers bleached kraft paperboard in the same weight range without the 95% chemical fiber requirement. Five US tariff lines reflect the end-use specificity: base stock for milk cartons and similar liquid packaging (4804420010), folding carton stock (4804420020), tray and cup base stock (4804420030), general packaging base stock (4804420040), and other kraft paper/paperboard (4804420050). Canada is the leading supplier, with France and Germany also significant sources.

The 95% chemical wood fiber requirement in 480442 effectively limits the heading to virgin-fiber SBS and similar high-purity grades, excluding recycled-content or mechanical-pulp-blended boards. Importers of bleached kraft paperboard in the 150–225 g/m² range should obtain mill certificates confirming fiber composition. Boards with significant recycled or mechanical fiber content fall to 480449 regardless of basis weight or bleaching.
When a product is manufactured and marketed specifically as folding carton stock, 4804420020 is the appropriate line. If the same board is sold for general packaging applications without a specific folding carton designation, 4804420040 or 4804420050 may apply. The purchase order, mill specification sheet, and product data sheet describing the intended end-use are the key classification support documents.
