Products classified under HTS 8504.90.96.34
Silicon Steel Laminations for Power Transformer Cores
Thin silicon steel sheets designed for stacking into laminated cores used in electrical power transformers. These laminations reduce eddy current losses through electrical insulation between layers. Classified under HTS 8504.90.96.34 as laminations specifically for incorporation into stacked cores of transformers.
CRGO Steel Laminations for Distribution Transformer Cores
Cold-rolled grain-oriented (CRGO) electrical steel laminations cut to precise shapes for stacking into distribution transformer cores. The grain orientation minimizes core losses in 50/60 Hz applications. HTS 8504.90.96.34 applies to these transformer-specific stacked core laminations.
Amorphous Metal Laminations for Energy-Efficient Transformer Cores
Thin amorphous metal alloy ribbons cut into laminations for stacking into high-efficiency distribution transformer cores. These offer lower core losses than traditional silicon steel. Specifically covered by HTS 8504.90.96.34 for transformer stacked core laminations.
High B-value Silicon Steel Laminations for Large Power Transformers
Hi-B (high magnetic flux density) silicon steel laminations for step-up/step-down power transformers over 10 MVA capacity. Precision cut for three-phase core stacking configurations. HTS 8504.90.96.34 designates these for stacked transformer core assembly.
Step-Lap Joint Silicon Steel Laminations for Transformer Cores
Precision-cut silicon steel laminations designed with step-lap geometry for minimized joint losses in stacked transformer cores. Used in both distribution and power transformers for improved efficiency. Covered under HTS 8504.90.96.34 for stacked core laminations.
3% Silicon Steel Laminations for Industrial Furnace Transformers
3% silicon content electrical steel laminations for high-temperature industrial furnace and rectifier transformers. Cut patterns accommodate special core configurations for heavy industrial use. HTS 8504.90.96.34 for transformer stacked core laminations.
Domain-Refined Silicon Steel Laminations for Premium Transformers
Domain-refined grain-oriented silicon steel laminations with laser scribing for ultra-low core loss in premium distribution transformers. Precision stacking reduces no-load losses significantly. HTS 8504.90.96.34 specifically for transformer core laminations.
