Limes and lemons exports from Colombia

How we count

• Every line of the export declarations (provisional and definitive) that DIAN, Colombia's customs, publishes under tariff line 0805.50.10.00, 0805.50.21.00, and 0805.50.22.00. Frozen and processed goods are under other tariff lines and are not counted.
• Each declaration counts once. DIAN publishes a declaration again when it is amended; the latest version replaces the earlier one.
• Tonnes are the net weight declared. Boxes are the commercial units of the lines declared in boxes.
• A shipment belongs to the ISO week (Monday to Sunday) of its shipment date. A season is made of whole weeks.
• Past seasons are compared week for week on the same calendar weeks a year before (week 34 against week 34), and only when our data covers them completely: a season the import history does not reach back to is not shown.
• DIAN replaces provisional declarations with definitive ones weeks to months after shipment, so the latest 8 weeks are incomplete: the chart draws only a dashed estimate for them, where it is reliable. What is declared so far is shown only in grey, labelled "so far", and is never quoted as a week's figure. The tonnes and values of the declarations still provisional are expected values: the provisional filings, which often overstate the tonnage, scaled by the exporter's historical ratio of definitive to provisional figures (over the declarations that became definitive in the last six months; the pooled ratio of the other exporters for an exporter with little history).
• Where it is reliable, the chart shows an estimate for the incomplete weeks (dashed): the tonnage declared so far divided by the share of a week's final tonnage that is usually declared by then, measured on the last 26 complete weeks. A week that is less than about half in gets no estimate. It is replaced by the declarations as they arrive. In the table and the latest-week card, the tonnage declared so far is shown in grey, labelled "so far", next to the estimate.
