Changes to the Electronic Waybill (Carta de Porte) 2026: What the Agribusiness Sector Needs to Know

The regulatory framework for the Electronic Waybill (Carta de Porte) continues to evolve to simplify processes and strengthen control across the agribusiness supply chain. Joint General Resolution No. 5821/2026 introduces amendments to the regulations previously established by Joint General Resolution No. 5017/2021, directly impacting producers and operators in the sector.

Below, we outline the main changes and their implications.

Who can request the Waybill under the new regulation?

Entities included in the Simplified Agricultural Information System (SISA) will be able to request the document, including:

• Producers registered in the system
• Grain trade operators with one or more registered facilities

With this update, the mandatory reference to the Unified Registry of Agribusiness Chain Operators (RUCA) is eliminated, simplifying the registration framework.

Key requirement to issue the document

To issue the Waybill, operators must have an active plant status in SISA.
This replaces the previous requirement of having an active registration in RUCA.

Platform for submitting the request

The request must be completed through the “Electronic Waybill (Carta de Porte)” service on the Customs and Revenue Control Agency (ARCA) portal, using a Tax Identification Password (Clave Fiscal) with Security Level 3.

New responsibilities for the issuer

The issuer remains responsible for the details and quantities reported, but the regulation now explicitly requires compliance with the maximum vehicle weight limits established by Decree No. 32/2018, strengthening control over transported loads.

Changes to the Short-Haul Motor Transport Waybill

Key updates include:

• Replacing the RUCA registration requirement as “Storage Operator” with the condition of having the destination facility active in SISA
• Eliminating the requirement to transport goods specifically to the nearest storage facility

These changes provide greater operational flexibility for sector participants.

Consequences of non-compliance

In addition to the penalties established in Law No. 11,683, non-compliance may result in:

• Operator inactivation
• Inactivation of facilities registered in SISA

This framework replaces the previous RUCA-related sanctions.

Effective date

The new regulatory framework entered into force on February 10, 2026, the date of its publication in the Official Gazette.
