Import Tips

Provide thickness and density certifications to prove slab form, preventing reclassification as finished gaskets

Label clearly as 'vulcanized sheets/slabs' to align with HTS description and avoid Chapter 40 scrutiny

Check for FDA compliance if used in food/pharma gaskets, requiring additional safety data
