Import Tips
• Ensure the gold cladding is mechanically applied (e.g
• by hot-rolling or welding) and not electroplated
• Provide tube dimensions and end-use documentation to support the semi-manufactured classification
• If the tubes are cut to length or threaded, they may be considered 'worked' and fall under other headings
