Import Tips
• Obtain lab tests confirming natural slate composition to differentiate from synthetic or agglomerated imitations
• Declare exact working processes (e.g
• sawing, splitting) to support classification as 'worked slate'
• Comply with ASTM C406 standards for roofing slate if targeting U.S. construction specs during import
