HS Code for Automatic resistance welder

Automatic resistance welders are classified under HS code 851521 due to their primary function and operational characteristics. This classification specifically covers welding machines and apparatus designed for resistance welding of metal, which operate either fully or partly automatically. The description further clarifies that these machines may or may not possess the capability for cutting. The core criteria for this classification are the resistance welding technology employed, the automatic or semi-automatic nature of their operation, and their application in processing metal components.

Products Included

• Automatic spot welding machines
• Automatic seam welding machines
• Automatic projection welding machines
• Automatic flash butt welding machines
• Robotic resistance welding cells

Common Misclassification

A common misclassification occurs with HS code 851531, which covers arc welding machines that are fully or partly automatic. The distinction lies in the welding principle: 851521 is for resistance welding, while 851531 is for arc welding. Another point of confusion can be with 851529, which covers other resistance welding machines that are not automatic. The key differentiator for 851521 is the explicit requirement for fully or partly automatic operation, distinguishing it from manual or semi-automatic resistance welders that lack automated control.

FAQ

What is the HS code for Automatic resistance welder?

The HS code for an automatic resistance welder is 851521. This code specifically applies to machines designed for resistance welding of metal, operating either fully or partly automatically, and may include cutting capabilities.

What is the difference between resistance welding and arc welding machines?

Resistance welding machines (HS 851521) join metals by applying pressure and passing a high electric current through the workpieces, generating heat at the interface due to electrical resistance. Arc welding machines (HS 851531), conversely, use an electric arc to melt and fuse the metals, often with the addition of filler material. The fundamental difference lies in the heat generation mechanism and the presence or absence of an electric arc.
