Import Tips
• Include technical specs showing leak rates below 10^-9 sccs for high-vacuum certification during import declaration
• Avoid common pitfalls by labeling as 'semiconductor process valve' to distinguish from general plumbing valves
• Ensure supplier provides RoHS compliance docs, as EU re-export may require it for electronics manufacturing components
