Logistics and Customs: How to Build a Supply Chain Without Surprises

[Mila Eryomina]

In international trade, the supplier-carrier-customs agent-recipient chain operates like a system of interconnected vessels: a failure in one link immediately impacts the others, resulting in delays, fines, and damaged reputation. When companies plan contracts, routes, packaging, and documentation in advance, and engage an experienced customs broker, the risk of border congestion and unnecessary expenses is significantly reduced, especially when a specialized agency, such as the Chilean import service at https://agenciaoyarzun.cl/servicios/importaciones-2/, is involved, helping to adapt to local requirements.

Supplier: the starting point of all logistics

Most logistics problems begin not at the port or even at the border, but at the supplier's warehouse. If at this stage product codes are incorrectly specified, specifications are incomplete, certificates of origin or quality documents are missing, the errors will travel with the cargo. The recipient often learns of discrepancies only after the container is at the terminal, and the clock for free storage is ticking.

A competent supplier will agree on the product list, descriptions, and labeling with the buyer in advance, clarifying which documents will be required by customs authorities in the importing country and which by the carrier. This avoids situations where the cargo has already been shipped, but the original certificates or the correct invoice are still waiting to arrive via email or courier.

Carrier: More than just getting from point A to point B

The carrier is responsible not only for the movement of goods but also for ensuring deadlines, the integrity of the cargo, and the proper execution of shipping documents. Their thorough understanding of the specifics of the route determines whether your container will travel directly or be stuck in a transit port for weeks.

A competent carrier provides advance notice of terminal congestion periods, seasonal risks, and possible schedule changes. Ideally, they work closely with the customs agent to ensure that by the time the vessel or vehicle arrives, all documents are ready for submission, and shipment information is correctly entered into the control and accounting systems.

Customs Agent: A Navigator Between Rules and Reality

Customs legislation in any country is regularly updated, and in Latin America, local peculiarities of ports, agencies, and regulatory bodies are added to this. A customs agent becomes a navigator between formal regulations and practical practices: they know which documents are actually checked at a particular checkpoint, what questions inspectors typically ask, and what nuances in the product description may raise suspicion.

The broker helps correctly classify goods according to the Commodity Nomenclature of Foreign Economic Activity (CN VED), select the appropriate duty and tax rates, and assess the availability of preferential treatment or benefits under free trade agreements. It advises on the additional permits and approvals required for a particular cargo and optimizes the document flow between the supplier, carrier, and recipient, drawing on the practical experience and real-life cases of local agencies like https://agenciaoyarzun.cl/servicios/exportaciones-2/, which handles export flows to Chile.

Recipient: the final link, which should not be passive

The recipient of the cargo often views themselves as merely "waiting" for the goods to arrive. In reality, they actively influence the speed and predictability of the entire supply chain. It is the importer who most often draws up the contract with the customs agent, arranges for the payment of duties and taxes, and agrees on the terms of storage and subsequent delivery to the final warehouse.

If the recipient promptly checks draft declarations, clarifies any disputes with the broker, and pre-books transport for the removal of goods from the port or terminal, the risk of additional expenses for demurrage or rerouting is significantly reduced. It is important that the employee responsible for foreign trade activities be involved in communication with the supplier and carrier before the first shipment, rather than being involved only upon the vessel's arrival.

Link synchronization: how to avoid customs bottlenecks

A supply chain operates without surprises when all participants understand not only their own responsibilities but also the actions of those next to them. The supplier must understand which invoice and product description terms are critical for customs clearance. The carrier must understand which document submission deadlines are crucial to ensure the shipment doesn't get stuck at the border due to missing data in electronic systems. The customs agent must understand how changes in the region, new regulations, or inspection campaigns affect specific shipments.

The key principle here is parallel processes. While the supplier is preparing documents and cargo, the recipient is already signing a contract with the broker, and the carrier is coordinating the transshipment schedule and terms. Anything that can be done in advance is not postponed until the moment of arrival. The fewer decisions made "after" the arrival of a container or truck, the less likely the company will be faced with the need to urgently reissue documents, pay for expedited terminal services, or arrange temporary storage.

The role of a professional broker in risk and budget management

A professional customs agent effectively becomes a co-logistics agent: they don't simply fill out declarations, but help plan the entire chain based on actual risks. During the planning stage, they suggest route options based on customs burdens, advise on which documents to submit in advance, what can be digitalized, and what must be in the original.

This approach allows for the forecasting of total customs clearance and logistics costs even before the main contract is signed. The company budgets for actual duties, VAT, fees, and terminal services, understanding where savings can be achieved by using a different regime or port of call, and where savings will result in delays and subsequent fines.

How to build a long-lasting and effective connection

A stable supply chain isn't built in a single shipment. Companies that regularly work with foreign suppliers and Latin American markets benefit from building a stable pool of partners: trusted suppliers, reliable carriers, and experienced customs agents. A well-established history of interaction reduces the number of new questions to ask each new shipping season and allows for proven scenarios.

When all parties view each other as long-term partners, they are engaged in a shared outcome: the supplier is more attentive to documents and deadlines, the carrier provides advance notice of possible route changes, and the agent warns of upcoming regulatory changes and offers alternatives. As a result, the "supplier-carrier-customs agent-recipient" chain is transformed from a set of disparate services into a unified system that operates predictably, transparently, and truly "without surprises."
