In this article, you'll learn in detail about the main documents required for import customs clearance, why they are important and how a specialized company can make the whole process easier.
What is Import Customs Clearance?
O import customs clearance is the fiscal and administrative process carried out to clear goods arriving in Brazil from other countries. It is conducted through Siscomex (Integrated Foreign Trade System), where the operation data is recorded for analysis by the Federal Revenue Service.
The aim of this process is to ensure that the import complies with Brazilian legislation, that taxes are collected correctly and that the goods do not pose any health, environmental or economic risks.
This is a mandatory step for any company wishing to bring products from abroad legally and efficiently. And for this process to go smoothly, the correct presentation of documentation is crucial.
Main Documents Required for Import Customs Clearance
The documentation required can vary according to the type of goods, the customs regime used and the country of origin. However, there are some documents that are considered standard and indispensable in the vast majority of processes.
Import Declaration (DI) or Single Import Declaration (DUIMP)
A Import Declaration is the document that formalizes the start of the customs clearance process. The new version, known as DUIMP, It is gradually replacing the DI and concentrates a lot of information in a single record, making it easier to monitor the operation.
This document gathers data on the importer, the foreign supplier, the transport, the cargo and the tax classification of the goods.
Commercial Invoice
The commercial invoice is issued by the exporter and acts as proof of an international sale. It must contain information such as:
- Name and address of exporter and importer
- Detailed product description
- Quantity and unit value
- Payment terms and incoterm used
The invoice is essential for calculating taxes and checking the goods at the time of clearance.
Bill of Lading (BL, AWB or CRT)
This is the document that proves the international transportation of goods. Depending on the modal, it can be called:
- BL (Bill of Lading) for maritime transport
- AWB (Air Waybill) for air transport
- CRT (Road Bill of Lading) for land transportation
This document is needed to prove possession and shipment of the goods.
Packing List
Although not mandatory in all cases, the packing list is highly recommended, especially when there are multiple volumes. It describes the contents of each package, facilitating the physical checking of the cargo and speeding up the work of customs inspection.
Import License (LI), When Applicable
Some products require specific licenses before the goods arrive. This may involve authorizations from agencies such as Anvisa, Inmetro, Ibama or Mapa. These documents need to be provided before the DI or DUIMP is issued, at the risk of the cargo being held up or penalties being imposed.
Proof of Payment of Taxes
Customs clearance of import requires the payment of taxes such as II (Import Tax), IPI (Tax on Industrialized Products), PIS, Cofins and ICMS. These taxes are paid using forms such as DARF and DAE, proof of which must be presented when the cargo is cleared.
Radar Importer Registration
Although it is not a physical “document”, it is essential that the importer is previously authorized in the Federal Revenue's Radar system. Without this authorization, the clearance process cannot even begin.
Consequences of Incomplete or Incorrect Documentation
Any documentary failure during the import customs clearance can have serious consequences, such as
- Delays in cargo release
- Payment of fines for formal infringements
