Import Tips
• Ensure the diamond wire is classified as an accessory to wafer slicing saws, not as a general cutting tool, which would fall under a different heading
• Have documentation ready to demonstrate its specific use in semiconductor boule slicing, such as wire diameter and diamond grit specifications
• Check if the wire qualifies for duty relief under the Machinery Remission Program, as it may be considered a part of the manufacturing process
