4707.90.00.00 - Other, including unsorted waste and scrap

This HTS classification, 4707.90.00.00, encompasses recovered paper and paperboard that does not fit into the more specific categories outlined for unbleached kraft paper, bleached chemical pulp paper, or mechanically pulped paper. It serves as a residual category for various types of waste and scrap paper and paperboard, including unsorted materials. This means that if a shipment of recovered paper cannot be definitively classified under 4707.10, 4707.20, or 4707.30 due to mixed materials, lack of specific pulp type identification, or general unsorted nature, it will fall under this "Other" designation.

The key differentiator for 4707.90.00.00 is its exclusion from the defined types of recovered paper. For instance, it does not include the specifically described unbleached kraft paper and corrugated paperboard (4707.10.00.00), nor does it cover paper primarily made from bleached chemical pulp without mass coloring (4707.20.00). Furthermore, it is distinct from paper derived mainly from mechanical pulp, such as old newspapers and journals (4707.30.00). This category is for materials that don't meet the precise criteria of these preceding headings, often due to a mix of different paper types or the absence of identifiable characteristics that would place them elsewhere.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 4707.90.00.00 relies solely on the determination that the recovered paper or paperboard does not qualify for any of the more specific sibling classifications. Practical application often involves examining the physical state and composition of the waste material. If an item is a mixed collection of various paper types or a type of paper not explicitly mentioned in the preceding subheadings, and it is intended for reprocessing into pulp, it would be classified here.
