4804.52.00.10 - Base stock for milk cartons and other beverage containers

This classification covers bleached kraft paper and paperboard specifically designed for use as base stock in the manufacturing of milk cartons and other beverage containers. The key characteristic is that these papers are uniformly bleached throughout the mass, ensuring a consistent and appealing appearance for printed packaging. Furthermore, a crucial defining feature is that more than 95 percent of the total fiber content must consist of wood fibers obtained through a chemical pulping process, indicating high quality and specific performance properties necessary for liquid packaging.

Distinguishing this category from its siblings, the primary differentiator is the specific composition and intended end-use. While other kraft papers and paperboards might be uncoated and weigh over 225 g/m², this particular classification is defined by its high percentage of chemically processed wood fibers and its specialized application in beverage packaging. The uniform bleaching ensures suitability for food-grade contact and printability, setting it apart from less refined or uncoated kraft materials.

As this is a leaf node in the HTS classification, there are no further subcategories. The classification is specifically tailored to identify this precise type of material used in a dedicated industry. Classification into this sub-heading relies heavily on confirming the material's composition (over 95% chemically processed wood fiber) and its intended purpose as base stock for beverage containers, often evidenced by its physical properties like absorbency, strength, and print receptiveness.
