Import Tips
• Confirm that the weighing sensor is designed solely for Czochralski pullers of heading 84.72, as this is key to classification
• If the sensor is a general-purpose weighing device, it may be classified under heading 84.23
• Keep documentation of the specific puller model it is intended for to support your declaration
