Unit value within commodity line (HS6)

tt008.commodity.unit-value-hs6 reported

Containerised customs value per kg inside a FIXED HS6 line, which is the only level at which a change can be read as being about the goods rather than the mix. HS6 is also the deepest level common to both directions — imports publish to HS10, exports only to HS6. Lines under 50 tonnes in a month are excluded as too thin to carry a ratio. Call it unit value, never quality.

We pulled this number.

STATUS: WITHDRAWN · SINCE 1970-01 · RETURNS WHEN THE CONDITION BELOW IS MET

COVERAGE INCOMPLETE. HS6 is fetched on demand, not as a standing archive — it is roughly 12.6x the rows of HS2 and the full history would exceed the free disk. The archive currently holds a single HS6 month for two ports. Lift when the intended window is present for the ports a claim is about, verified by a month count per port. We will not serve data we cannot stand behind, so this page stays up but the numbers do not.
