4811.51.20.20 - Folding carton stock

This HTS category, 4811.51.20.20, specifically classifies folding carton stock. This refers to paperboard that has been bleached, weighs more than 150 grams per square meter, and is provided in rolls or rectangular sheets suitable for the manufacture of folding boxes and cartons. The material may be coated, impregnated, or covered with plastics, but not with adhesives. The key characteristic is its intended use in the creation of foldable packaging.

This classification is distinguished from its sibling category, 4811.51.20.30, which covers base stock for trays, dishes, plates, cups, and similar disposable or serving items. While both may be made of coated paperboard, the folding carton stock is designed for the structural requirements of assembled boxes, whereas the other sibling is intended for forming rigid or semi-rigid container shapes for individual servings or food containment.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 4811.51.20.20 depends on meeting all the preceding criteria: being bleached, weighing over 150 g/m², being supplied in rolls or specific sheet dimensions, having a thickness of 0.3 mm or more, and its primary designation as material for folding cartons.
