Import Tips & Compliance
• Provide evidence of Czochralski or float zone method specificity to confirm auxiliary status for 8444 machines
• Label equipment clearly as 'semiconductor crystal growth apparatus' to prevent reclassification
• Avoid pitfall of bulk import without end-use certificates, which can trigger audits for dual-use technology
