7209.16.00.40 - “Advanced” or “ultra” of a kind described in statistical note 4 to this chapter

This HTS category, 7209.16.00.40, specifically classifies cold-rolled flat-rolled products of iron or non-alloy steel that are of a width of 600 mm or more and are not further worked than cold-rolled. The defining characteristic for this subcategory is that these products are "advanced" or "ultra" high-strength steel, as further detailed in Statistical Note 4 to Chapter 72. These steels possess enhanced mechanical properties, often achieved through specialized manufacturing processes beyond standard cold reduction and annealing.

The distinction between this category and its sibling, 7209.16.00.45 ("Other"), lies directly in the steel's strength characteristics. While both fall under the broader umbrella of annealed, high-strength steel with a thickness exceeding 1 mm but less than 3 mm, this specific code is reserved for those meeting the "advanced" or "ultra" criteria defined by the statistical note. Therefore, classification hinges on whether the steel exhibits these superior strength properties, which are typically associated with applications requiring exceptional durability and performance.

As this is a leaf node, there are no further subcategories. Classification to this specific code requires confirmation that the material meets the advanced or ultra high-strength steel criteria as outlined in the relevant statistical note. This typically involves examining metallurgical specifications and potentially testing for specific yield and tensile strength values, which exceed those of standard high-strength steels.
