Import Tips
• Label shipments clearly as 'uncovered innerspring units' with dimension certifications to prevent customs disputes
• Include material safety data sheets for steel coatings to comply with import regulations on metal bedding components
• Avoid bundling with fabric or foam layers, as sets may classify under 9404.29.1000 or as complete mattresses
