4804.42.00.10 - Base stock for milk cartons and other beverage containers

This classification covers bleached kraft paper and paperboard specifically manufactured for use as base stock in the production of milk cartons and other beverage containers. The defining characteristics are its uniform bleaching throughout the mass and that over 95% of its fiber content is derived from wood processed chemically. This ensures the material's suitability for direct food contact, rigidity, and printability required for beverage packaging.

Distinguishing this category from its siblings is crucial. The "Other" sibling at this level would encompass bleached kraft paper and paperboard that, while meeting the weight requirements and being bleached, is not specifically intended or manufactured for beverage container base stock, or does not meet the strict 95% wood fiber requirement. Therefore, the primary differentiator lies in the intended end-use and the specific fiber composition for specialized packaging applications.

As this is a leaf node, there are no further subcategories. The classification ends here, signifying that any product meeting all the preceding criteria falls directly under this HTS code. Classification professionals should focus on verifying the uniform bleaching, the weight range (over 150 g/m² but less than 225 g/m²), and confirming the 95% minimum wood fiber content obtained through a chemical process, along with evidence of its intended use in beverage container manufacturing.
