Transformer Grade Grain-Oriented Silicon Steel 0.27mm x 450mm
High-permeability grain-oriented silicon electrical steel, 0.27mm thickness and 450mm width, optimized for power transformer cores. Falls under HTS 7226.11.10.00 due to alloy steel composition, silicon electrical steel properties, and grain orientation with width ≥300mm but <600mm.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width less than 300mm
The width threshold determines subheading; under 300mm moves to 7226.11.20.
If not alloy steel (carbon steel equivalent)
Silicon steel without sufficient alloying elements defaults to Chapter 72 carbon steel flat products.
If further worked with electrical insulation coating
Chapter note defines 'further worked' including nonmetallic coatings, shifting to processed alloy steel categories.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Certify grain orientation via ASTM standards; ensure no further working like coating to stay in base heading; watch for high-strength steel misclassification if yield strength exceeds note (a) thresholds
