Importers and procurement teams ask us the same question before every order: “What is the HS code for an ultrasonic welding machine?” This guide lists the codes commonly used for ultrasonic welding machines, horns, transducers and cutting blades — plus the declaration notes that keep customs clearance smooth. Codes below are commonly used practice, not legal advice: always confirm with your customs broker before declaring.
HS Codes for Ultrasonic Welding Equipment
| Item | Commonly Used HS Code | Notes |
|---|---|---|
| Ultrasonic plastic welding machine | 8515.80 | “Other machines and apparatus for welding”; most frequent classification for plastic welders |
| Ultrasonic metal welding machine | 8515.80 | Same heading; some brokers file under 8515.21 (resistance welding) — confirm locally |
| Ultrasonic wire harness welder / splicer | 8515.80 | Declare with cross-section range in the description |
| Ultrasonic horn / sonotrode / booster | 8466.93 or 8487.90 | Parts of machines; classification depends on whether it ships with a machine or separately |
| Ultrasonic transducer | 8543.70 / 8504.40 | Piezo stack classified as electrical apparatus; broker choice varies by country |
| Ultrasonic generator | 8504.40 | Static converter (frequency converter) heading |
| Ultrasonic cutting blade (titanium) | 8208.00 | Knives and cutting blades, for machines |
| Ultrasonic food cutter / cake cutting machine | 8438.80 | Bakery machinery heading; some declare as 8515.80 — confirm |
Declaration Notes That Prevent Delays
- Describe the function, not just the name. “Ultrasonic plastic welding machine, 20 kHz, 2,600 W, for welding plastic parts” clears faster than “welder”.
- Machines vs parts. A horn shipping together with a machine can often go on the same invoice line; shipping separately, it’s a part — different heading, different duty.
- Keep invoices consistent. Model, frequency, power and quantity must match across invoice, packing list and B/L.
- Certificates. CE declaration of conformity available on request; some markets want additional electrical safety documents.

FAQ
Which code should I declare for a combined weld + degating machine?
Declare by primary function — welding. Your broker makes the final call for your market.
Do duty rates differ between plastic and metal welders?
They can, even within the same heading. For example, importers in India and South Asia should check duty and GST treatment with their broker before ordering.
Can you put the HS code on the invoice?
Yes — we pre-fill the commonly used code on request, clearly marked for customs convenience.
