Import Tips
• Provide alloy-specific datasheets; Hastelloy's unique composition demands proof of high-nickel status
• Avoid common pitfall of declaring as generic stainless—customs audits often reclassify without documentation
• For heat exchanger use, bundle with pressure vessel certification to prevent end-use disputes
