Import Tips
• The CBSA may classify this as semiconductor manufacturing equipment under heading 84.86 if it is solely for boule production; be prepared to justify the mineral-working function
• Check if the puller qualifies for duty relief under the Machinery Remission Program
• Provide a detailed description of the pulling and grinding processes to avoid reclassification
