Import Tips

Submit chemical analysis reports confirming high nickel content (>30%) to distinguish from standard alloy steels

Label as 'cold-rolled seamless' with dimensions; pitfalls include misdeclaration as hot-finished leading to 7304.41

Comply with NACE MR0175 for sour service if applicable, ensuring proper documentation for customs
