4820.10.20.30 - Sewn composition books with dimensions of 152.4-381 mm (6" - 15"), inclusive (small side) X 222.5-381 mm (8.75" -15"), inclusive (large side)

This HTS category specifically covers sewn composition books that fall within defined size parameters. These are typically notebooks characterized by their sewn binding, distinguishing them from stapled or spiral-bound varieties. The specified dimensions, ranging from 152.4-381 mm (6" - 15") for the small side and 222.5-381 mm (8.75" - 15") for the large side, are crucial classification criteria. The "sewn" aspect is a key identifier, differentiating these books from other types of notebooks and stationery.

Compared to its sibling categories, this classification is distinct. While 4820.10.20.10 covers diaries and address books (which have a more defined personal record-keeping purpose) and 4820.10.20.20 encompasses memorandum and letter pads (designed for brief notes and correspondence), this category is reserved for composition books. Furthermore, it is differentiated from 4820.10.20.40, which covers other types of notebooks within the same dimensional range but lacking the specific "sewn" construction.

As this HTS code represents a leaf node in the classification structure, there are no further subcategories under this specific entry. Classification within this code is therefore determined by adherence to the defined product type (composition book), the binding method (sewn), and the precise dimensional specifications outlined. This ensures accurate categorization for trade purposes, avoiding ambiguity with other stationery items.
