Customs Clearance

Customs clearance is the set of legal and documentary procedures carried out before customs so that goods can enter or leave a country legally. Without an approved clearance, the cargo is not released: it stays held in the primary customs zone (port, airport or terminal) until the process is complete.

In practice, clearing goods means filing a customs declaration with the correct tariff classification code, declaring the customs value of the goods, calculating and paying the customs charges (duties, fees and taxes) and passing the authority's inspection (in Argentina, the customs service that reports to ARCA, the federal tax agency formerly known as AFIP, through the Malvina system). Only then is the release issued, which authorizes the goods to be picked up or shipped.

This whole operation generates and consumes documentation: commercial invoice, packing list, bill of lading, certificates of origin, permits. Centralizing, reading and validating those documents is part of what Arconte organizes, so the customs file stays complete and traceable instead of scattered across emails and spreadsheets.

Customs clearance is the hinge of foreign trade: without it, an import or export cannot be completed legally. Although it is usually outsourced to a customs broker (the licensed agent who acts before the authority), understanding the process is key for any company that buys or sells abroad, because the costs, the lead times and the risk of the cargo getting held up all depend on it.

How it works, step by step

The process follows a fairly stable sequence, regardless of the country:

• Prior documentation: the commercial invoice, packing list, bill of lading and, depending on the product, the certificate of origin, licenses or health permits are gathered.
• Tariff classification: the tariff classification code (a Harmonized System code) is assigned, which defines which duties and restrictions apply. A mistake here can mean overpaying or a fine.
• Valuation and declaration: the customs value is determined (usually on a CIF basis for imports) and the declaration is filed in the authority's IT system.
• Assessment and payment: import or export duties, the statistics fee, VAT, withholdings and other taxes are calculated and paid.
• Risk selection and inspection: the system assigns a channel (in Argentina: green, orange or red). Green releases with no review, orange reviews the documents and red adds a physical inspection of the goods.
• Release: once the inspection is passed, customs authorizes pickup (import) or loading (export).

Why it matters for the business

A poorly managed clearance translates into money and time. Every day of delay in port can generate demurrage or detention charges on the container, storage costs and, in supply chains with expiration dates or seasonality, a stockout. A missing document or a questionable classification is enough to stop everything. That is why keeping documents in order is not an administrative detail: it is what separates a clearance that takes hours from one that takes weeks.

A concrete example (Argentina)

An Argentine importer of auto parts agrees to a purchase from China under the FOB Incoterm. When the container arrives in Buenos Aires, its customs broker files the declaration in the Malvina system, classifies each SKU under its tariff code, declares the CIF value and calculates the duties and taxes. The system assigns it to the red channel: customs opens the container and checks the physical goods against the packing list and the invoice. Because the documents are complete and consistent, the inspection wraps up quickly and the cargo is released. If the invoice did not match what was declared, the clearance would be flagged and the container would keep adding days of detention.

Customs clearance vs customs broker

They are often confused, but they are not the same: one is the process, the other is who carries it out.

Common mistakes

• Misclassifying the tariff code, which changes the duty rate or triggers unexpected restrictions.
• Declaring a customs value that is inconsistent with the invoice, which triggers flags and adjustments.
• Starting the clearance without complete documentation, especially the certificate of origin needed for tariff preferences.
• Ignoring non-tariff restrictions (licenses, registrations, reviews by other agencies), which hold up the cargo even if the duties and taxes are paid.

In short, customs clearance is where logistics, taxes and documentation meet. Mastering it, or at least having visibility into its status and its file, avoids surprises in the total cost of the operation and keeps the supply chain moving.
