Import Tips

Include technical data sheets specifying metal coating thickness and diamond particle size distribution to substantiate classification

Avoid common error of classifying as synthetic industrial diamonds under 7104 if powder fineness qualifies it for Chapter 71

Ensure invoice details synthetic nature and coating to prevent scrutiny under natural diamond provisions
