About HS Code 850490

This HS code covers parts of electrical transformers, static converters, and inductors, playing a crucial role in the global electronics and power equipment supply chain. It includes components and sub-assemblies specifically designed for the repair, assembly, or manufacturing of the complete apparatus classified under heading 8504. Importers and exporters are typically specialized component manufacturers, electronics assembly plants, and repair service providers who require specific parts to build or maintain power conversion and magnetic devices. The trade in these parts is essential for supporting the production of everything from large industrial transformers to miniature electronic inductors, emphasizing precision, material quality, and compatibility with specific end products.

Products Under This Code

Transformer cores, inductor windings, heatsinks for converters, power module housings, rectifier bridge components, control boards for inverters, transformer bobbins

Real World Examples

Siemens transformer cores, ABB converter modules, TDK ferrite cores, Vishay heatsinks, Infineon power semiconductor packages

Common Misclassification

Frequently confused with the complete apparatus codes like 850421 (liquid dielectric transformers) or 850440 (static converters) if the 'part' is a significant sub-assembly. Also, general electronic components (e.g., 8534 for printed circuits) if not clearly identifiable as a part of 8504 apparatus.
