Import Tips & Compliance
• Document base metal as steel despite plating; plating under 20% doesn't change classification
• Include thread gauge certifications; pitfall is rejecting shipments for mismatched pitch declarations
• Label packages with size, plating type, and quantity accurately for CBP exams
