A composite statistical heading used in US export data, SITC 99400 bundles three distinct data elements: an estimate of non-Canadian low-value export shipments, a compiled aggregate of low-value shipments destined for Canada, and Canadian-bound export transactions where the commodity was not identified by kind. The heading exists because the US–Canada border generates a high volume of small and mixed shipments that are processed under simplified procedures, making commodity-level classification impractical for every transaction. Export compliance officers should note that this heading reflects statistical methodology, not a tariff or Schedule B classification.
