6907.40.10.11 - Finishing ceramics, the largest surface area of which is capable of being enclosed in a square the side of which is 30 cm or less

This HTS category, 6907.40.10.11, specifically covers unglazed finishing ceramics where the largest surface area of the individual piece is capable of being enclosed within a square with sides of 30 centimeters or less. This designation is crucial for differentiating smaller decorative or functional ceramic elements from larger tiling or paving materials. Examples within this category would include unglazed ceramic border pieces, small decorative inserts, or unglazed ceramic components intended for architectural finishing where size is a defining characteristic.

This specific subcategory is distinguished from its sibling, 6907.40.10.51 ("Other"), by the explicit size limitation applied to the largest surface area. While both fall under unglazed finishing ceramics, the "30 cm or less" criterion in 6907.40.10.11 is the primary determinant for classification. Items exceeding this size, even if unglazed and used for finishing purposes, would likely fall under the broader "Other" category at this level, or potentially a different HTS code altogether depending on their specific characteristics and intended use.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, the focus remains on accurately applying the established criteria for inclusion. The classification hinges on the inherent material (ceramic), its surface treatment (unglazed), its intended use (finishing), and most importantly, the dimensional constraint of its largest surface area. Proper measurement and assessment of this largest surface area is paramount for correct classification under this specific HTS code.
