Share of US general imports from all countries (World). 12-month totals sum the 12 months ending in each month, and are shown only when all 12 months have a Census figure. All other origins is World minus the five highlighted partners (China, Vietnam, Taiwan, Mexico and India). It includes the other watchlist partners, which are also drawn individually as thin grey lines.
A missing month means Census published no figure for that partner and product. That usually reflects little or no recorded trade, but we don't assume zero, so the line shows a gap. Gaps in this view: Cambodia.

This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau.
These are US-side figures: what the US Census Bureau records as imported into the US from each partner (general imports, by country of origin). A change in where the US buys a product shows a change in recorded origin. On its own it is not evidence that goods were transshipped or rerouted through another country, and it does not show where the goods were made.
