Import Tips
• Cleanroom-compatible packaging required; provide semiconductor end-use certification to expedite FDA/CBP review
• Monitor for nickel fluoride formation in monel containers; common issue is purity drop during transit
• Pair with NF2 or CF4 imports under complementary codes for process kits
