• Label shipments clearly as 'geophysical seismographs' to prevent CBP reclassification as general accelerometers
• Include seismic response spectra validation data in commercial invoices for duty assessment
• Obtain advance rulings for hybrid units combining seismic and structural health monitoring functions
