Import Tips
• Verify fuse voltage rating exceeds 1,000V and obtain IEEE/ANSI certifications to avoid reclassification
• Include detailed technical specs and test reports in documentation to prove 'other fuse' status
• Beware of common pitfalls like incorrect voltage declaration leading to Chapter 85 heading 8536 misclassification
