Import Tips
• Document compatibility with specific wafer grinder models from statistical note (a)(ii)(A) to substantiate classification
• Avoid common pitfall of declaring as general pumps (8413); specify semiconductor thermal processing application
• Maintain bills of materials showing integration with temperature-controlled grinding spindles
