Import Tips

Verify heat exchanger material certification as brazed aluminum to confirm 8419.60.10.00 classification; steel exchangers shift to other subheadings

Include detailed process flow diagrams in documentation proving gas liquefaction function to avoid misclassification as general heat exchangers

Ensure pressure vessel compliance with ASME codes and obtain proper certifications for cryogenic operation to prevent customs delays
