Last updated: April 2026 dataHeavier-weight bleached kraft paperboard — over 150 g/m² and composed of more than 95% chemically processed wood fiber — serves as a primary substrate for folding cartons, pharmaceutical packaging, and high-end consumer goods boxes where stiffness and printability must coexist. The grammage threshold separating this heading from its lighter counterpart is a firm classification line, making accurate basis-weight documentation essential for correct tariff treatment. Surface treatments such as clay coating or polyethylene extrusion are common in this weight range and do not disqualify the product from this heading provided the fiber-content criterion is met.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A PE-extrusion coating is generally treated as a surface covering that keeps the product within the coated kraft paperboard headings, provided the underlying substrate still meets the over-95% chemical wood fiber and over-150 g/m² criteria. However, heavily laminated or composite constructions may shift classification, so borderline products should be reviewed with a licensed customs broker.
Mill certificates or technical data sheets specifying pulp composition (confirming over 95% chemical-process fiber by weight) are the standard supporting documents. Some entries may also require a CBP Form 28 response with laboratory analysis if CBP questions the fiber percentage.
