NOTES:
*Due to non-disclosure requirements certain 10-digit Schedule B commodity classifications are
subject to suppression and require a change in aggregation. As a result, Advanced Technology
Product exports are overstated by $481 million in May 2011. For additional information
see www.census.gov/ft900.

*Data not available on a Balance of Payments basis.  For information on
