Import Tips & Compliance
• Verify the bar stock is not further worked than hot-rolled or forged, as machining or surface treatment would change classification
• Keep documentation of the nickel content (72%) to support the high-nickel alloy steel classification
• Check if the gas turbine application requires any special import permits
