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
