HS-6 · Subheading
850423
Electrical transformers; liquid dielectric, having a power handling capacity exceeding 10,000kVA
Heading 8504 — Electric transformers, static converters (e.g. rectifiers) and inductors
Chapter 85: Electrical machinery and equipment
Plain-language overview
Use HS-6 850423 when classifying large electrical transformers with a liquid dielectric that have a power handling capacity exceeding 10,000 kVA. For example, a shipment of a 15,000 kVA transformer used in a power generation facility falls under this code.
This code specifically targets high-capacity transformers, distinguishing them from smaller models classified under HS-6 850421 and HS-6 850422, which cover transformers with lower power handling capacities. Understanding this difference is crucial for accurate customs declarations.
Transformers classified under 850423 are typically used in industrial applications, such as substations or large manufacturing plants, where significant electrical power is required. They often come with liquid cooling systems to manage heat during operation.
When importing or exporting these transformers, ensure that you have the correct specifications and documentation, including capacity ratings and cooling methods, to avoid classification issues.
