7220.12 - Of a thickness of less than 4.75 mm:

This HTS category, 7220.12, specifically covers flat-rolled products of stainless steel that are less than 600 mm in width and have a thickness of less than 4.75 mm. These products are further worked than hot-rolled, implying they have undergone processes such as cold-rolling to achieve their final dimensions and surface finish. The material must be stainless steel, and the dimensions are critical for accurate classification.

Distinguishing this category from its sibling, 7220.11.00.00, is solely based on thickness. While 7220.11.00.00 pertains to stainless steel flat-rolled products with a thickness of 4.75 mm or more, this current category (7220.12) is exclusively for those with a thickness *less than* 4.75 mm. Both categories share the common characteristics of being flat-rolled stainless steel and having a width under 600 mm, but the thickness threshold is the defining difference.

Within the 7220.12 category, further subdivisions are made based on the width of the rolled product. The subcategories, 7220.12.10.00 and 7220.12.50.00, differentiate between stainless steel flat-rolled products of a thickness less than 4.75 mm that are 300 mm or more in width, and those less than 300 mm in width, respectively. This granular breakdown allows for more precise classification based on the specific dimensions of the material.
