HS Code for Ultrasonic welding machine

Ultrasonic welding machines are classified under HS code 8515.80. Heading 8515 covers electric, laser, other light or photon beam, ultrasonic, electron beam, magnetic pulse or plasma arc soldering, brazing or welding machines and apparatus. While subheadings 8515.11 through 8515.39 cover specific types of soldering and metal welding, 8515.80 is the residual category for \"Other machines and apparatus.\" Since ultrasonic welding is often used for joining plastics or non-ferrous metals through high-frequency acoustic vibrations rather than traditional electric arcs, it is categorized here. The process creates a solid-state weld by applying local heat through friction and pressure. This classification is appropriate because the primary function is the joining of materials through an ultrasonic electrical process, distinguishing it from mechanical cutting tools. The equipment usually includes an ultrasonic generator, a transducer, and a horn (sonotrode).

Products Included

• Ultrasonic plastic welding systems
• Ultrasonic metal welders (e.g., for battery tabs)
• Ultrasonic wire bonders for electronics
• Ultrasonic tube sealers
• Integrated ultrasonic welding workstations

Common Misclassification

The most common misclassification is 8456.20, which is for ultrasonic machines that remove material (cutting). If the machine is used for slitting textiles without removing material, it stays in 8515.80, but if it removes a strip of material, it moves to 8456. Another error is 8479.89 (other mechanical appliances), which should only be used if the welding function is not the primary purpose.

FAQ

What is the HS code for Ultrasonic welding machine?

The HS code for ultrasonic welding machines and apparatus is 8515.80.

Does this code include the ultrasonic generator?

Yes, if the generator is imported with the welding head as a complete system, the entire apparatus is classified under 8515.80.
