Product classification
HS code for Ultrasonic welding machine: 8515.80
Welding machines and apparatus, n.e.c. in heading no. 8515, whether or not capable of cutting.
Classification of ultrasonic welding machine under HS 8515.80
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).

Codes often confused with 8515.80
Common mistake. 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.
Top exporters and importers of HS 851580 (the code used for ultrasonic welding machine), 2025
In 2025, the largest exporter of HS 851580 (the code used for ultrasonic welding machine) in UN Comtrade data was China, with 33% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about ultrasonic welding machine
What is the HS code for Ultrasonic welding machine?
The HS code for Ultrasonic welding machine is 851580 (Welding machines and apparatus; n.e.c. in heading no. 8515, whether or not capable of cutting). The HS code for ultrasonic welding machines and apparatus is 8515.80.
How do I classify Ultrasonic welding machine for customs?
Ultrasonic welding machine is classified under HS code 851580 — Welding machines and apparatus; n.e.c. in heading no. 8515, whether or not capable of cutting. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of ultrasonic welding machine (HS 851580)?
In 2025, the top exporters of HS 851580 (the code used for ultrasonic welding machine) in UN Comtrade data were China ($1.1B, 33% of world exports), Germany ($690M) and Switzerland ($272M). World exports came to about $3.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of ultrasonic welding machine (HS 851580)?
In 2025, the top importers of HS 851580 (the code used for ultrasonic welding machine) in UN Comtrade data were the United States ($487M, 16% of world imports), China ($235M) and Mexico ($226M). World imports came to about $3.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Ultrasonic welding machine the same in all countries?
The base HS code 851580 for Ultrasonic welding machine is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for ultrasonic welding machine in Brazil?
Brazil splits HS 851580 into 2 NCM codes, so the right one for ultrasonic welding machine depends on the product's details: 8515.80.10 (Laser welding machines), 8515.80.90 (Other welding and hot-spraying machines).
