HS Code for Brown kraft paperboard

Brown kraft paperboard with a weight of 225 g/m² or more is classified under HS code 480451. This classification is reserved for the heaviest grades of unbleached, uncoated kraft paperboard. Like other products in heading 4804, it must be composed of at least 80% chemical wood fibers produced via the sulfate or soda process. The high grammage indicates a product designed for high-strength applications, such as heavy-duty shipping containers, floor protection sheets, or rigid packaging components. The distinction between this code and 480441 is purely based on the weight threshold of 225 g/m². Customs authorities often require laboratory testing of the grammage and fiber analysis to confirm that the product meets the "kraft" definition and the specific weight requirements for this subheading. The product must be presented in rolls or sheets and must not have undergone any bleaching or coating processes. Its natural brown color and high tear resistance are defining characteristics that make it suitable for industrial environments where durability is paramount.

Products Included

Common Misclassification

The most common misclassification occurs with HS code 480441, which covers the same material but at a lower weight (between 150 and 225 g/m²). Another frequent error involves HS code 4805, which covers other uncoated paper and paperboard; however, 4805 is used when the fiber content does not meet the 80% chemical sulfate pulp requirement. If the paperboard is bleached, it falls under 480452. If it is coated with plastic or minerals, it is classified under 4810 or 4811. It is vital to verify the exact weight per square meter to ensure the 225 g/m² threshold is correctly applied.
