HS Code for Choke

The electrical component known as a choke is classified under HS code 8504.50, which is designated for other inductors. In the context of electrical engineering, a choke is an inductor used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency direct current (DC) or AC. Heading 8504 is a broad category that encompasses electrical transformers, static converters, and inductors. According to the General Rules of Interpretation (GRI) 1 and 6, the classification is determined by the specific function and technical characteristics of the component. Since a choke is a type of inductor that does not perform the function of a transformer (changing voltage) or a converter (changing AC to DC), it is classified under the specific subheading for inductors. Chapter 85 covers electrical machinery and equipment and parts thereof. The Explanatory Notes to heading 8504 specify that inductors consist of a coil of wire which, when energized with an alternating current, produces a magnetic field. Chokes are used extensively in power supplies, radio frequency applications, and electronic filters. The classification remains 8504.50 regardless of whether the choke has a core made of iron, ferrite, or other materials, or is an air-core inductor, provided it is not part of a more specific assembly classified elsewhere in the nomenclature.

Common Misclassification

Chokes are often misclassified under HS code 8504.10 if they are used as ballasts for discharge lamps or tubes. While ballasts contain inductors, they are a specific functional assembly. Another common error is confusing chokes with capacitors (HS code 8532) or resistors (HS code 8533) due to their similar appearance in small-scale electronic circuits. It is vital to identify the inductive property to ensure 8504.50 is used.

FAQ

What is the HS code for Choke?
