Import Tips

• - Verify insulator strength rating (e.g

• 70kN, 120kN) matches technical specifications for customs valuation

• - Provide ANSI C29.2 or IEC 60383 certification to avoid reclassification as general ceramic ware

• - Common pitfall: Missing pollution performance data can trigger additional testing requirements
