Import Tips

• Verify fiber composition via lab testing to confirm 100% polypropylene and avoid reclassification to other synthetic fibers

• Include manufacturer specs on denier, length, and crimp in documentation to prove unprocessed state

• Watch for contamination; even minor impurities can trigger scrutiny under Chapter 55 purity rules
