Import Tips
• Provide APA trademark certification confirming exposure rating (Exposure 1) and span ratings for structural panels
• Test for shear and bending strength per ASTM D3043 to distinguish from non-structural particle board
• Declare accurately as OSB vs MDF; misdescription leads to 4410.11 (MDF) reclassification and penalties
