Overview

HTS code 8515.21.00.00 specifically covers fully or partly automatic machines and apparatus designed for resistance welding of metal. These machines utilize electrical resistance to generate heat at the point of joining, thereby fusing metal components together. The "fully or partly automatic" designation indicates that these machines can perform the welding operation with minimal or no manual intervention, often incorporating features for workpiece feeding, positioning, and weld parameter control.

This category is distinguished from its sibling, HTS code 8515.29.00.00 ("Other"), by the precise nature of the welding operation. While 8515.21.00.00 is dedicated to resistance welding, the "Other" category would encompass machines for resistance welding that do not meet the fully or partly automatic criteria or are otherwise not specifically enumerated. Therefore, the key differentiator lies in the level of automation and the specific welding methodology employed.

As this is a leaf node, there are no further subcategories within 8515.21.00.00. Classification within this heading relies on confirming that the apparatus in question performs resistance welding and operates in a fully or partly automatic manner. Examples include automated spot welding machines used in automotive manufacturing or robotic arms equipped with resistance welding tools for high-volume production.
