Import Tips & Compliance
• Specify exact nominal pipe sizes (NPS) for both ends in commercial invoice to match statistical reporting
• Include coating specifications (e.g
• bituminous) as surface treatments affect valuation
• Beware of transshipment documentation requirements for cast iron from high-risk origins
