Import Tips
• Submit chemical analysis certificates proving Incoloy alloy composition meets 'other alloy steel' definition
• Ensure seamless process documentation, as nickel alloy welded tubes classify differently
• Declare for industrial heat exchanger use to avoid consumer product misclassification
