Import Tips

Provide material test reports confirming nonalloy steel chemistry to distinguish from alloy grades under 7304.59

Ensure dimensional compliance with customs inspection; minor OD deviations can trigger reclassification

Label as 'boiler tube' only if certified; otherwise classify as general pipe to avoid Chapter 73 tube-specific headings
