What Documentation You Need to Move Cargo into Chile

Moving cargo into Chile is not complicated, but it is strict. The difference between a trip that clears the border in a couple of hours and one that gets stuck at the Los Horcones complex almost always comes down to documentation. One missing paper, one mismatched detail, and the truck does not move.

In this guide we go over what documentation you need to export cargo overland into Chile, who handles each part and how to avoid the most common delays. The idea is for you to know what will be asked of you before you reach the Andes.

The basic documents for any cargo

For a standard overland Argentina–Chile export, these are the papers that cannot be missing:

Commercial invoice

This is the document backing the sale. It must match exactly the goods traveling: description, quantities, values. Any difference between what is declared and what is on the truck is a problem at the border.

Packing list

It details how the cargo is packed: packages, weights, dimensions. It lets customs verify the goods without having to open everything. A clear packing list speeds up the inspection.

MIC/DTA

The International Cargo Manifest / Customs Transit Declaration is the central document of international road transit. It covers the movement of goods between Mercosur countries and associates, and it is what customs checks to authorize the crossing.

CRT (International Waybill)

This is the international transport contract. It identifies the sender, the consignee, the carrier and the goods. It is the international equivalent of the transport delivery note, and it is legally valid in both countries.

The documents that depend on the goods

Beyond the basics, depending on what you carry, specific papers are added:

• Phytosanitary certificate: for goods of plant origin (fruit, agricultural products, wood). Issued by SENASA.
• Certificate of origin: when you need to prove the origin of the goods for tariff benefits.
• ADR documentation: for dangerous goods (chemicals, fuels, certain industrial inputs). It includes the driver and unit authorization.
• Special permits: for oversized cargo or goods with particular characteristics.

The rule is simple: the more sensitive the goods, the more documentation customs requires. That is why it is best to define this before loading, not on the road.

Who does what: broker and carrier

A common confusion is to think the carrier "does the customs paperwork". That is not the case, and understanding the split avoids misunderstandings:

• The customs broker handles the documentary process and clearance. They are the ones who process and present the documentation to customs. You work with your broker or the importer's broker in Chile.
• The carrier (us) provides the unit and driver data for the MIC/DTA and the CRT, carries the physical documentation during the trip, and coordinates the crossing times so everything arrives at the border in sync.

When the two work coordinated, the crossing flows. When each goes their own way, delays appear.

How we handle it at Rutas del Sur

We have over 40 years crossing the Cristo Redentor Pass, and that taught us one thing: documentation is reviewed before departure, not at the border. A missing paper at Los Horcones means the truck stopped, adding hours or days.

That is why, on every crossing:

• We coordinate with your broker so the documentation is complete before departure.
• We provide the unit and driver data for the MIC/DTA and CRT on time.
• Our drivers know the border complex and the real crossing times.
• We flag if something is missing, before it becomes a problem in the Andes.

We do not do the customs clearance —that is the broker's job— but we do make sure the transport side is flawless and in sync with yours.

To read more about the corridor, see our international Argentina–Chile transport page and the Mendoza–Chile route. Before traveling in winter, it is worth checking the Cristo Redentor Pass status.

How the crossing works at the Los Horcones complex

Understanding the mechanics of the border control helps to gauge the timing. The crossing into Chile is done at the Los Horcones complex, on the Argentine side, where integrated control operates: both countries' procedures are concentrated at a single point, which speeds up the crossing compared to the old double-control scheme.

The truck arrives, presents the documentation, and customs verifies that everything matches: what is declared in the invoice and the MIC/DTA against what it actually transports. If the documentation is complete and correct, the procedure is quick. If something is missing or there is an inconsistency, the cargo waits until it is resolved, and that is where the hours go.

Real times depend on three things: the number of trucks in line (which rises in high season and drops in winter), the state of the pass, and —above all— that your documentation is flawless. You do not control the first two; you do control the third. That is why we insist so much on reviewing everything before departure.

Special cases worth anticipating

Not all cargo crosses the same way. There are situations that require extra preparation and that, if you anticipate them, are not a problem:

Dangerous goods (ADR). Chemicals, fuels, certain inputs for mining or oil & gas. They need ADR documentation, an authorized driver and an approved unit. This is not something to improvise: it is coordinated in advance.

Products of animal or plant origin. Fruit, food, wood: besides the phytosanitary certificate, they may have restrictions or specific windows. It is best to check this before loading.

Oversized cargo. Large machinery, special equipment. They require specific transit permits in both countries and, sometimes, an escort. The process takes time, so you start early.

High-value goods. They add insurance requirements and, sometimes, security during transit. It is best to declare it from the start to plan the trip accordingly.

The general rule is the same for all cases: the sooner we know, the better we coordinate. A special load flagged in advance crosses without trouble; the same load improvised is a guaranteed wait.

A tip if you're just starting to export to Chile

If it is your first operation on the corridor, do not put it together alone. The first time, questions always come up: which certificate applies, how to fill in a certain field, in what order things are done. Lean on a good broker for the customs side and a carrier with experience on the crossing for the logistics side. Those two, working coordinated, get you out of most problems before they exist.

Over time, recurring exports become routine: the documentation gets standardized, the timing becomes predictable and the crossing stops being a headache. But that learning is much faster if you start with people who have already walked the path. We have over 40 years on this corridor, so if you have questions about the transport side, ask without hesitation.

In short

To move cargo into Chile you need, at a minimum, an invoice, packing list, MIC/DTA and CRT, plus the certificates your goods require. The broker handles clearance; the carrier coordinates and carries the physical documentation. The key to not getting stuck is to review everything before departure.
