HS Code for Transformer

Electrical transformers with a power handling capacity exceeding 1 kVA but not exceeding 16 kVA are classified under HS code 8504.32. This classification follows a hierarchical structure within heading 8504, which covers electrical transformers, static converters, and inductors. According to the Chapter 85 notes and the subheading structure, transformers are first divided by whether they are liquid dielectric (oil-filled) or not. If the transformer is a 'dry-type' (not liquid dielectric), it falls under the 'Other transformers' category. Within that category, the specific code is determined by the rated power handling capacity. Code 8504.32 is specifically for those with a capacity between 1 kVA and 16 kVA. This range covers many industrial and commercial transformers used for voltage regulation and isolation in machinery and control systems.

Products Included

• Dry-type isolation transformers (2 kVA to 15 kVA)
• Step-down transformers for industrial machinery
• Single-phase and three-phase dry transformers within the 1-16 kVA range
• Control power transformers for electrical panels
• Voltage stabilizers using transformer technology within this power range

Common Misclassification

Misclassification often occurs by selecting the wrong power bracket. HS code 8504.31 is for transformers not exceeding 1 kVA, while 8504.33 is for those between 16 kVA and 500 kVA. Importers must verify the kVA rating on the nameplate to ensure the correct code. Additionally, if the transformer uses oil or another liquid for cooling and insulation, it must be classified under 8504.21, regardless of its kVA rating, as liquid dielectric transformers have their own dedicated subheadings.

FAQ

What is the HS code for a 5 kVA dry transformer?

A 5 kVA dry-type transformer is classified under HS code 8504.32.

What if the transformer is exactly 1 kVA?

If the capacity does not exceed 1 kVA, it should be classified under 8504.31. The 8504.32 code only applies once the capacity exceeds 1 kVA.
