Import Tips
• Provide engineering drawings specifying use as guardrail component to support 'other tubes' classification
• Check for zinc coating weight documentation; insufficient galvanization may lead to non-galvanized reclassification
• Avoid bundling with fittings, as sets could classify under different headings for assembled structures
