Import Tips
• Verify pressure ratings and material certifications (e.g
• ASME stamps) to meet U.S. safety standards for pressure vessels
• Include detailed engineering drawings and test reports in documentation to avoid customs reclassification as parts
• Check for anti-dumping duties if sourced from China; common pitfall is mislabeling as domestic-use equipment
