Silicon-Electrical Steel Flat-Rolled Products, 600mm Wide or More

Grain-oriented electrical steel (GOES) is processed so that magnetic domains align in the rolling direction, minimizing core losses in transformers where flux flows in one direction. Non-grain-oriented (NGOES) has isotropic magnetic properties suited for rotating machines like motors and generators. Both fall under SITC 67511 for wide flat-rolled products, but they may be separated at the HTS 10-digit level and can be subject to different antidumping orders, so specifying orientation in purchase contracts and import documentation is important.

Yes. The US has maintained antidumping and countervailing duty orders on grain-oriented electrical steel from multiple countries. Non-grain-oriented electrical steel has also been subject to trade remedy investigations. Importers should check current Commerce Department and ITC orders and any scope rulings before sourcing, as the product specifications that define order scope — silicon content, thickness, coating — are highly technical.
