HS Code for Rotary converter

A rotary converter is classified under HS code 8502.40. This classification is found in Chapter 85, which covers electrical machinery and equipment. Heading 8502 specifically includes electric generating sets and rotary converters. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter, or frequency converter. It combines the functions of an electric motor and a generator in a single unit with a common armature and a single magnetic field. The classification is determined by the mechanical nature of the conversion process; because the device uses rotating parts to transform electrical energy from one form to another (e.g., AC to DC), it is distinct from static conversion equipment.

Products Included

• AC to DC rotary converters
• DC to AC rotary converters
• Rotary phase converters
• Rotary frequency changers
• Combined motor-generator sets for power conversion

Common Misclassification

The most common misclassification for rotary converters is HS code 8504.40, which covers static converters such as rectifiers, inverters, and UPS systems. The primary difference is that 8504.40 applies to solid-state or electronic devices with no moving parts, whereas 8502.40 is strictly for machines that utilize physical rotation. Another error is classifying them as standard electric motors under 8501, but since the primary function is the conversion of current or frequency rather than providing mechanical power, 8502.40 is the correct and more specific code.

FAQ

What is the HS code for a rotary converter?

The HS code for electric rotary converters is 8502.40.

Can a static inverter be classified under this code?

No, static inverters do not have rotating components and must be classified under HS code 8504.40.
