Import Tips & Compliance
• Provide mill test reports confirming stainless steel composition to prevent reclassification as carbon steel
• Label with exact dimensions and NPS (Nominal Pipe Size) to comply with statistical reporting
• Avoid bundling multiple fittings as sets, which could trigger classification under parts headings like 7307.99 if not purely fittings
