Import Tips
• Obtain EPA or CARB Executive Order certification documentation to prove compliance with emissions standards
• Verify filter substrate material (e.g
• cordierite) and dimensions match vehicle specifications to prevent misclassification
• Include proof of intended use for internal combustion engines to avoid reclassification as general air filters
