Import Tips
• Provide engineering drawings showing compatibility only with 9031.80.40 projectors to prevent general fixture classification
• Label shipments clearly as 'profile projector accessories' with model cross-references
• Avoid importing with universal machine vises, which could classify under 8466 tool-holding appliances
