²Pipeline and unknown shipments are combined because data on region-to-region flows by pipeline are statistically uncertain.
³Data do not include imports and exports that pass through the United States from a foreign origin to a foreign destination by any mode.

Notes: Numbers may not add to total due to rounding.
