Import Tips
• Include technical data sheets proving moisture resistance derives from facing treatment, not altering plaster base classification
• Label shipments clearly as 'Type X' or mold-resistant to comply with ASTM C1396 standards during customs review
• Avoid bundling with metal framing, as sets may classify under different provisions for assembled systems
