7213.91.30.20 - Of welding quality wire rods of a kind described in statistical note 7 to this chapter

This HTS category, 7213.91.30.20, specifically classifies wire rods of iron or nonalloy steel that are hot-rolled and supplied in irregularly wound coils. These wire rods are further defined by their circular cross-section, measuring less than 14 mm in diameter. The key defining characteristic for this specific subcategory is their intended use for welding quality applications. They are not tempered, treated, or otherwise partly manufactured beyond the hot-rolling process.

Distinguishing this category from its siblings is crucial for accurate classification. While other categories at this level might cover wire rods for tire cord-quality (7213.91.30.11) or cold heading quality (7213.91.30.15) applications, this classification is exclusively for those intended for welding processes. The general "Other" category (7213.91.30.93) serves as a residual for any wire rods meeting the preceding criteria but not specifically designated for tire cord, cold heading, or welding quality.

As this HTS code represents a leaf node, there are no further subdivisions. Classification under 7213.91.30.20 is determined by the product's physical form (hot-rolled wire rod in coils, circular cross-section less than 14mm diameter) and its specific intended purpose, which is confirmed by its designation as "welding quality." This means that the wire rod must be suitable for use in welding processes and often possesses specific metallurgical properties that facilitate this application.
