Import Tips & Compliance
• Declare the control board as a part of wafer grinding machines under 8475.90.00, not as a printed circuit board under heading 85.34
• Provide CBSA with the specific wafer grinder model it is designed for to support the classification
• If the control board is a printed circuit assembly with active elements, verify whether it falls under supplementary note 1 to Chapter 84
