Import value density by gateway

tt008.gateway.value-density-import reported

Containerised import customs value per kg. A LEVEL, comparable across ports in the same month. Its MOVEMENT over time is not interpretable as a price change — at this aggregation a shift in the commodity mix moves it just as readily.

Withdrawn from publication

LEVEL ONLY, AND THE SERIES CANNOT SAY SO BY ITSELF. Comparable across ports in a given month; its movement over time is a mix index wearing a price label. Suspended until it is published together with the HS6 decomposition that separates the two.
