What customs filings really tell you about price

Every shipment that crosses a border carries an invoice value presented to customs. Divide that by the declared net weight and you have a unit price for that shipment — not a wholesale list price, not a retail price, but the figure two parties actually put on paper for goods that actually moved. Across a month of filings, those figures describe what a market pays more precisely than any survey.

They have to be handled with care, and every report spells out exactly how. Four rules do most of the work.

1. Report medians and ranges, not averages

The median declared price for vanilla beans in December 2025 was $49.50 per kilogram, with the middle half of trade between $26.85 and $88.50. An average would have been dragged towards whichever extreme happened to ship that month. The median is the middle observation — one odd shipment can't move it — and the range tells you how spread out the market is around it.

2. Leave out what has no weight — and say so

Net weight was declared on 73 of the 123 filings. The other 50, carrying 5.2 per cent of value, were declared in packages, pieces or units, so they have no unit price. They stay in every value total and are left out of every price figure, and we say so under each affected table. A price series that quietly includes or excludes them can't be checked.

3. Deal with odd filings rather than ignore them

One Ugandan shipment to Switzerland was declared at 1 kilogram for $6,679 — a weight error, not a $6,679 price. One 10-kilogram shipment to Korea was declared at a total value of $1.00 — a nominal or sample declaration. Both stay in the value totals, both are left out of the price figures, and both are named in the limits section. You can see exactly which two records were treated differently, and why.

4. Let the prices show you the bands

Within the vanilla code, the spread between $26.85 and $88.50 isn't noise. It separates three businesses: flavour powder below $5, bulk beans for industry between $25 and $60, and gourmet retail above $60. Inside the industrial band, the spread turned out to be about origin, not quality — Indonesian planifolia to one US processor at $49.50 to $54.71, Ugandan beans to another at $28.18 to $32.14, for a comparable product.

That is the finding an exporter can price against. The report's recommendation followed directly: offer Indonesian bulk to US food manufacturers at $49 to $52 per kilogram — inside the band the current supplier cleared at — and don't benchmark against the Ugandan prices. Below $45 a seller is competing with Uganda on Uganda's terms, and giving up roughly ten per cent of what those buyers demonstrably paid.

Declared values are the closest thing there is to what a market really pays and what competitors really charge. They are not wholesale or retail prices, and a report should never present them as such.
