Import Tips
• Distinguish toppers from full mattresses via thickness/weight on entry docs; toppers still classify as mattresses if bedding-designed
• Provide lab tests for gel content to confirm cellular plastic nature, avoiding chemical additive disputes
• Use HTSUS advisory rulings for hybrid foam/gel products to preempt reclassification risks
