7215.50.00.18 - With a diameter or cross section measuring 76 mm or more but not exceeding 228 mm

This HTS category, 7215.50.00.18, specifically classifies bars and rods of iron or non-alloy steel that are "other" than those covered by more specific subheadings, and have undergone no further working than cold-forming or cold-finishing. Crucially, these products must contain less than 0.25 percent carbon by weight. The defining characteristic of this particular classification is the physical dimension of the bar or rod: its diameter or cross-section must measure 76 millimeters or greater, but not exceed 228 millimeters.

This distinction is vital for accurate classification. Unlike its sibling category 7215.50.00.16, which covers bars and rods with a diameter or cross-section measuring *less than* 76 mm, this category addresses larger dimensions. Similarly, it differs from 7215.50.00.20, which applies to bars and rods with a diameter or cross-section *exceeding* 228 mm. Therefore, the range of 76 mm to 228 mm is the exclusive criterion that places goods within this specific subheading.

As a leaf node within the HTS, this category represents the most granular level of detail for this particular product type. There are no further subcategories. Classification under 7215.50.00.18 therefore hinges directly on meeting the material composition (less than 0.25% carbon), the working process (cold-formed or cold-finished), and the precise dimensional range (76 mm to 228 mm) specified.
