Import Tips
• Submit manufacturer's declaration linking the gearbox to specific paper calendar models for pulp/paperboard use
• Document gear ratio permanence (non-variable) to distinguish from manual multi-ratio changers
• Check for INA rulings on similar paper machine components to support your classification
