Import Tips
• Include quarry origin certificates to confirm basalt type and compliance with 'merely cut' processing limits
• Avoid bundling with mortar or fittings, as that could reclassify as a set under different headings
• Watch for customs scrutiny on 'roughness'; excessive trimming may trigger worked stone classification
