1kVA Single-Phase Step-Down Transformer
This 1kVA single-phase transformer steps down voltage from 240V to 120V for use in industrial control panels and machinery. It falls under HTS 8504.31.60.00 because it is an electrical transformer with a precise power handling capacity of 1 kVA, not exceeding the subheading limit. Designed for reliable power conversion without static rectification functions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If power handling exceeds 1 kVA
Transformers over 1 kVA shift to 8504.32, a different power capacity subheading with potentially different duties.
If includes built-in rectifier or static converter
Devices combining transformation with power conversion functions classify under static converters rather than pure transformers.
If imported as replacement parts, not complete units
Transformer cores or windings without housings are parts of 8504, separate from assembled complete transformers.

Import Tips & Compliance
• Verify exact power rating documentation (precisely 1 kVA) as customs may require test reports to confirm classification within 8504.31.60.00
• Ensure UL or equivalent safety certifications for electrical transformers to meet US import standards and avoid CBP holds
• Declare voltage ratings and insulation class accurately; mislabeling can lead to reclassification under higher-duty codes
