Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as general reactor vessel closure parts
Parts not specific to fuel cartridges classify under broader nuclear reactor parts in 8481.
If other zirconium alloy fittings without nuclear specification
General metal screws, bolts, and fittings fall under Chapter 73 if lacking fuel element design features.
If classified as turbine component closures
Material similarity leads to error; nuclear-specific pressure/temperature ratings distinguish classification.

Import Tips & Compliance
• Provide ultrasonic weld inspection reports and helium leak test data (<10^-7 cc/sec); certify to ASME Section III, Division 1
• Avoid common pitfall of missing nuclear end-use statement on commercial invoice
