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
