Import Tips
• Provide alloy certificates proving SmCo composition to distinguish from cheaper ferrite alternatives during customs review
• Declare intended end-use (e.g
• aerospace) in documentation to support classification and potential duty exemptions
• Ensure packaging prevents corrosion, as oxidation can lead to reclassification or rejection at entry
