Import Tips & Compliance

Certify heat treatment method (e.g

patenting process) matches tariff definition of 'heat treated' to prevent disputes

Watch for rust/discoloration; no duty allowance per Chapter 72 notes, so ensure proper packaging

Batch testing for diameter consistency avoids CBP measurement challenges at entry
