Import Tips
• Test alloy composition to confirm copper base exceeds 50% for proper subheading; spectrometry reports required
• Pair with heat pump assembly diagrams showing humidity control function to distinguish from Chapter 84 testing apparatus
• Watch for inadvertent Chapter 84 classification if marketed for semiconductor cleanroom use
