HS-4 · Heading
8504 — Electric transformers, static converters (e.g. rectifiers) and inductors
Chapter 85: Electrical machinery and equipment
Plain-language overview
Use HS-4 8504 when importing or exporting electric transformers, static converters, or inductors. For example, if you're shipping a liquid dielectric transformer with a power capacity of 800kVA, this heading applies. Understanding the specific subheading is crucial for compliance and accurate duty assessment.
When deciding between the subheadings, consider the power handling capacity of your transformers. For instance, HS-6 850421 covers transformers with a capacity not exceeding 650kVA, while HS-6 850422 is for those exceeding 650kVA but not exceeding 10,000kVA. Make sure to measure your equipment accurately to select the correct line.
If your product is a transformer with a capacity over 10,000kVA, you would use HS-6 850423. On the other hand, if you're dealing with smaller transformers, HS-6 850431 and 850432 cater to capacities up to 16kVA. Each subheading has specific criteria that must be met to ensure proper classification.
