With which countries

January–July 2026

Each line joins the start and a country this was sold to; it is a relationship, not a route.

Each line arrives from the country where the goods were made; it is a relationship, not a route. The other countries, pooled, and the codes that are not a country (free zones, ship stores) add up to US$ 550 thousand and have no line.

How it is measured

Where the figures come from
Every export and import declaration the Servicio Nacional de Aduanas processed since January 2025, added up as Aduanas publishes them in its open databases. Nothing is estimated. They are amounts of trade, not PuroChile indicators, and they are never divided by census figures.
FOB and CIF
Exports are valued FOB («free on board»): what the goods are worth loaded on the ship, plane or truck that takes them out of Chile. Imports are valued CIF («cost, insurance and freight»): what they are worth on arrival in Chile, with insurance and freight paid. That is how Aduanas publishes them. So «exports less imports» is not the Central Bank's trade balance, which values imports without insurance or freight.
Which months
The figures at the top add up January–July 2026: the months of this year both databases already carry, against the same months of 2025. Aduanas replaces the running year's database every month, so this year's months can still be corrected. «s/d» on a chart is a month the database does not carry — not a month without trade.
Changes
A change is shown only where the same months of the year before added up to at least US$ 1.0 million.
The codes
Aduanas classifies every good with a code of the Arancel Aduanero, which is the international Harmonized System with two Chilean digits added: 2 digits are the chapter (74, copper), 4 the heading (74.03, refined copper), 6 the subheading (7403.11, cathodes) and 8 Chile's own tariff line. Names are the Arancel's; in English, the Harmonized System 2022's. Chile's Section 0 and its 8-digit lines have no English text and are shown in Spanish.
Port and customs office
The port is where the cargo physically passes: loaded for an export, unloaded for an import. The customs office is the branch of the Service that processes the declaration. They are not always the same place: the Aduana de Antofagasta processes what is loaded at Mejillones.
What is not here
Customs agents: every declaration names the agent who filed it, but Aduanas's open databases leave that field out, and PuroChile does not estimate it.
A month at zero
A month with no bar is one in which nothing was declared under this code; «s/d» is one the database does not carry.
Tariff lines
The 8-digit lines are Chile's own: the Harmonized System stops at the subheading and each country opens its own lines below it. They have no English text, so they are named in the Arancel's Spanish.
