🔍 Important Notes

  • This calculator automatically determines freight classes from 50 to 400 based on your input dimensions and weight.
  • Class 500 (density less than 1 lb/ft³) requires manual assessment as it involves special handling considerations.
  • The highlighted rows in the table above show the density ranges used for automatic classification.
