7219.13.00 - Of a thickness of 3 mm or more but less than 4.75 mm

This HTS category, 7219.13.00, specifically classifies flat-rolled products of stainless steel that have undergone hot-rolling and are presented in coils. The critical defining characteristic for this subcategory is its thickness, which must be 3 mm or more but less than 4.75 mm. These are substantial, yet not excessively thick, steel products that are often used in structural applications, manufacturing components, or as intermediate goods for further processing.

This classification distinguishes itself from its sibling categories primarily by precise thickness ranges. Unlike 7219.11.00 and 7219.12.00, which cover thicker hot-rolled stainless steel coils (exceeding 10 mm and between 4.75 mm and 10 mm respectively), or 7219.14.00 which covers thinner coils (less than 3 mm), this category occupies a distinct mid-range thickness. The hot-rolled condition and presentation in coils are common to all these siblings, making thickness the sole differentiating factor at this level.

The subcategories within 7219.13.00 further refine the classification based on the post-rolling treatment. The "Not annealed or not pickled" designation separates products that have not undergone these common finishing processes. The "Other" designation typically encompasses coils that have been annealed, pickled, or subjected to other standard treatments that alter their surface characteristics or internal structure, allowing for finer distinctions in their intended use or subsequent manufacturing steps.
