HS code for Choke: 8504.50
Electrical inductors, n.e.c. in heading no. 8504.
Classification of choke under HS 8504.50
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.

Codes often confused with 8504.50
Common mistake. 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.
Top exporters and importers of HS 850450 (the code used for choke), 2025
In 2025, the largest exporter of HS 850450 (the code used for choke) in UN Comtrade data was China, with 26% of world exports; the largest importer in UN Comtrade data was the United States, with 19% 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).
