4805.91.70.00 - Weighing over 15 g/m² but not over 30 g/m²

This HTS classification, 4805.91.70.00, pertains to other uncoated paper and paperboard that is not further processed beyond the specifications outlined in Note 3 of Chapter 48. Specifically, it covers products that fall under the "other" category within uncoated paper and paperboard weighing 150 g/m² or less. The defining characteristic of this subcategory is its basis weight: it must weigh over 15 g/m² but not exceed 30 g/m².

This classification distinguishes itself from its sibling categories by its precise weight range. For instance, HTS code 4805.91.50.00 covers similar uncoated paper and paperboard that weighs *not over* 15 g/m², while HTS code 4805.91.90.00 applies to products weighing *over* 30 g/m². Therefore, the critical differentiating factor is the material's grammage.

As this is a leaf node within the HTS structure, there are no further subcategories for 4805.91.70.00. This means that once a product meets the criteria of being uncoated paper or paperboard, weighing 150 g/m² or less, and specifically falling within the 15 g/m² to 30 g/m² weight range, it is definitively classified under this code. Examples of such paper might include certain types of lightweight specialty papers, thin packaging papers, or papers used in specific printing applications where this weight profile is essential.
