U.S. imports of Bleached Uncoated Kraft Paperboard, 150–225 g/m², Over 95% Chemical Wood Fiber (HS 480442) totaled $464K in September 2026, imported from 8 countries.
Importers of Bleached Uncoated Kraft Paperboard, 150–225 g/m², Over 95% Chemical Wood Fiber paid $11K in duties in September 2026, an average duty rate of 2.41% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Bleached Uncoated Kraft Paperboard, 150–225 g/m², Over 95% Chemical Wood Fiber imports of $464K in September 2026 ran 47% below the year-to-date monthly average of $872K.
Last updated: September 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.
