Import Tips
• Provide pressure-temperature ratings and alloy composition to confirm auxiliary status and avoid parts classification
• Ensure labeling distinguishes from complete superheater units to prevent reclassification
• Watch for anti-dumping duties on certain steel tube imports used in superheaters
