Merchant Shipping System: What It Is and How to Register

Merchant shipping plays a fundamental role in civil waterway activities, and to ensure the necessary support and control of tax collection, the Merchant Shipping System was created.

But do you know what the Merchant Shipping System is and how it works? Are you familiar with the responsibilities of the merchant navy and the benefits of implementing this system?

In this article, we will explain what the Merchant Shipping System is, its function, and how the registration is done. Keep reading to learn more about this important system for logistics professionals, international trade, and medium to large business procurement.

What Is the Merchant Shipping System?

The Merchant Shipping System is a tool provided by the Federal Revenue Service that offers computerized support for the control and collection of the Additional Freight for the Renewal of the Merchant Navy (AFRMM). This control ranges from the registration of the Bill of Lading to the crediting in accounts linked to the Merchant Navy Fund.

By collecting data, the Merchant Shipping System calculates the AFRMM value for each bill of lading and records the amount determined in its database. This important tool is available on the Siscomex Carga platform, in the module for controlling cargo transported by waterway.

Siscomex Carga and Its Importance for the Merchant Shipping System

Siscomex Carga is a feature integrated into the Siscomex portal, aimed at handling information related to maritime cargo transportation operations. This integration is essential for the efficient control of the Merchant Shipping System since it allows for the quick and secure interaction of data.

In addition to promoting operational optimization and cost reduction, Siscomex Carga contributes to:

  • Speeding up the cargo clearance process, making it more efficient.
  • Improving the collection of AFRMM.
  • Creating mechanisms for automatic control for the integration of Regional Units.
  • Managing processes of tax benefits.

AFRMM: What Is Its Importance for the Merchant Shipping System?

Among the main optimization objectives provided by the Merchant Shipping System is the improvement of the collection of the Additional Freight for the Renewal of the Merchant Navy, known as AFRMM.

This collection is essential for the maintenance and expansion of the Brazilian Merchant Navy, which is responsible for commercial, fishing, and recreational activities on waterways.

The AFRMM is part of the so-called Cide taxes (Contribution of Intervention in the Economic Domain) and helps cover the cost of the Merchant Navy Fund. Taxation occurs at the time of unloading at the port and is related to the freight value.

What Are the Benefits of the Merchant Shipping System?

The creation of the Merchant Shipping System brings numerous benefits to those who need to control operations, and companies can now access the progress of their cargo in a simplified manner. Some of the benefits include:

  • Cost reduction in maritime cargo transportation.
  • More efficient inspection in Brazilian ports.
  • Quick delivery of goods.
  • Service integration.
  • Automatic collection of the Additional Freight.
  • Increased data reliability.
  • More effective resource management.

Additionally, the Merchant Shipping System allows for the advance availability of cargo loading and unloading operation data, segmented according to intervening criteria.

What Is the Role of the CE Mercante?

The Merchant Shipping System issues a number from the record, facilitating the AFRMM control. This number corresponds to the Electronic Merchant Knowledge, also known as CE Mercante.

This document is essential for providing detailed information about the transported goods to the customs authority, facilitating the control of the Additional Freight collection. The inspection of this documentation is done through digital certification.

Who Enters the CE Mercante Data into the System?

The companies involved in the logistics operation are responsible for transmitting the information for the issuance of the Electronic Merchant Knowledge. This information includes data such as the cargo manifest and the route of the vessel responsible for transportation.

After the issuance of CE Mercante, all aspects of cargo deconsolidation must be carried out by the responsible cargo agent.

How to Register in the Merchant Shipping System?

Registration in the Merchant Shipping System must be done by filling out a form available from the Federal Revenue Service. To do this, you need to obtain a digital certificate to validate the information.

This form can be filled out by deconsolidators, cargo agents, and consignees of transportation. However, for waterway transportation operations in Brazil, the company must first obtain a credential from ANTAQ (National Waterway Transportation Agency).


The Merchant Shipping System is an essential tool for controlling and optimizing operations within the Merchant Navy. With the integration provided by Siscomex Carga, it becomes faster and more efficient to manage AFRMM collection and ensure the proper functioning of civil waterway activities in Brazil.

Registration in the Merchant Shipping System is essential for companies wishing to operate in waterway transportation, ensuring compliance with legal requirements and providing more effective resource management.

With the information available on the platform, inspections become more efficient, and goods are delivered more quickly, benefiting the Brazilian economy and international trade.

In summary, the Merchant Shipping System is an important tool for professionals in logistics, international trade, and procurement from medium to large companies operating in waterway transportation, and registration is a crucial step for legal and efficient operation in this sector.
