Yes, for certain categories. The Department of Energy has issued rules restricting procurement of bulk-power system electric equipment — such as large power transformers — from suppliers connected to foreign adversaries. These restrictions apply to equipment used in the US electric grid and are separate from and in addition to any Section 301 or antidumping tariff obligations.

Electrical equipment spans dozens of HTS headings with meaningfully different duty rates and trade remedy exposures. A motor classified under one heading may face a different tariff than a generator under another, even if the products appear similar. Voltage thresholds, power ratings, and intended application all influence classification, making a product-level customs broker review essential before importation.
