Toroidal Transformer Core Laminations from Canada
Stamped and insulated steel laminations designed specifically for assembly into toroidal transformer cores used in power supplies. These parts fall under HTS 8504.90.96.46 as other parts of transformers, distinct from complete cores or windings. They enable efficient magnetic flux in high-performance transformers.

Import Tips
• Verify material composition (e.g
• grain-oriented silicon steel) matches transformer specifications to avoid reclassification as raw material under Chapter 72
• Include detailed engineering drawings showing transformer-specific design features in entry documentation
