Import Tips
• Super duplex requires ferrite content verification (35-65%); non-conforming material faces rejection
• Use FDA-equivalent cleanliness standards if any food-grade certification claimed erroneously
• Bundle with coupling stock under same entry but separate line items to avoid averaging issues
