6810.99.00.20 - In slabs of rectangular shape, with a length of 3 m or more and a width of 1.25 m or more

This HTS classification covers articles manufactured from cement, concrete, or artificial stone, which are not specifically covered by preceding headings within Chapter 68. These articles are further defined by their slab shape, specifically those with a rectangular configuration, a length of 3 meters or more, and a width of 1.25 meters or more. The material composition focuses on cementitious binders, often incorporating aggregates to form a solid structure.

The distinguishing factor for this category is the combination of the material (cement, concrete, artificial stone), the form (slabs), and the precise dimensions (length >= 3m, width >= 1.25m). Unlike sibling category 6810.99.00.40, which broadly covers "Other" articles of cement, concrete, or artificial stone that do not meet the specific dimensional criteria of this code, this classification is restricted to large, rectangular slabs. The emphasis is on the substantial size of the slabs, suggesting applications where large, monolithic pieces are required.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Therefore, the classification is concluded at this level, encompassing all qualifying articles that meet the material, form, and dimensional requirements. Importers and exporters should ensure that their goods precisely match the described physical characteristics to ensure correct classification and avoid discrepancies.
