Grain-Oriented Silicon Electrical Steel Coil 0.27mm x 150mm
This is a flat-rolled coil of grain-oriented silicon electrical steel with 3% silicon content, measuring 0.27mm thick and 150mm wide, designed for transformer cores. It falls under HTS 7226.11.90 as it is alloy steel containing silicon, grain-oriented for optimal magnetic properties, and under 300mm width. The grain orientation minimizes core losses in electrical applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not grain-oriented (non-oriented)
Non-grain-oriented silicon electrical steel falls under 7226.91 as it lacks directional magnetic properties required for 7226.11 grain-oriented classification.
If silicon content below electrical steel threshold
Lower silicon alloy flat-rolled products (<600mm width) classify under 7225.40 rather than silicon electrical steel in 7226.
If width 300mm to 600mm
Same grain-oriented silicon electrical steel but wider dimension exceeds 300mm limit, moving to 7226.19.90 subheading.

Import Tips & Compliance
• Provide mill test certificates verifying silicon content (>2.5%) and grain orientation to confirm classification under silicon electrical steel
• Ensure accurate width measurement (<300mm) as products 300-600mm shift to HTS 7226.11.10; measure uncoiled product
• Declare exact thickness and alloy composition to avoid reclassification; common pitfall is mislabeling non-grain-oriented as grain-oriented
