4811.51.20.10 - Base stock for milk cartons and other beverage containers 🖩

This HTS classification, 4811.51.20.10, specifically identifies base stock paper and paperboard that are bleached, weigh over 150 g/m², and are presented in dimensions suitable for industrial use in the production of beverage containers, such as milk cartons. The material is coated or covered with plastics, excluding those with adhesive properties, and possesses a thickness of 0.3 mm or more. This designation ensures that specialized paperboard designed for food contact and structural integrity in liquid containment is accurately categorized.

The "0.3 mm or more in thickness" designation serves as a critical differentiator at this level. It distinguishes these heavier-duty materials from lighter-weight papers and paperboards covered under preceding subheadings, which might be suitable for less demanding applications. The inclusion of this specific thickness requirement ensures that only those papers and paperboards with the requisite rigidity and barrier properties for carton manufacturing are classified here.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, the focus remains on the precise definition of the product itself. This classification covers the foundational material used to construct the robust walls and bottoms of cartons designed to hold beverages, emphasizing its role as a primary component in a manufacturing process. The key classification elements are the bleaching, weight, plastic coating (non-adhesive), specific dimensions, and the crucial thickness threshold of 0.3 mm or greater.
