| Scope |
| Item coverage The following items are excluded from the statistics: For exports only: - shipments to U.S. Armed Forces and diplomatic missions abroad for their own use; - shipments between the United States and Puerto Rico, between the United States and its possessions (including the Virgin Islands), and between these outlying areas; - exports from U.S. possessions; - in-transit shipments through the United States when documented as such with Customs; - transactions not considered to be of statistical importance such as personal and household effects; - temporary exports; - low-valued or non-commercial exports by mail and issued monetary coins of all component metals. For imports only: - value data for shipments valued under $1,251 (under $251, for textiles) are estimated for individual countries using factors based on the ratios of low-valued shipments to individual country totals. Therefore, the statistics for the individual commodity classifications are undercounted due to the exclusion of data for shipments valued under $1,251 (under $251 for textiles). The total value so excluded amounts to slightly less than 1 percent of the monthly import total. |
