Import Tips
• Require aerospace-grade titanium certifications matching semiconductor purity standards
• Submit photos and CAD files showing integration with Czochralski crystal processing equipment
• Avoid delays by pre-clearing with customs on 'other valve bodies' statistical reporting requirements
