Octo for cargo and customs

Cargo leaves a trail in customs. Octo helps keep your system on the same trail.

Customs offices oversee the entry, stay, movement and exit of cargo units and goods. The Portal Único Siscomex publishes a REST API, which includes import cargo control for the waterway mode, and Siscomex Carga allows the loading and unloading report to be filed by web service. Octo can prepare the integration of your company's system, for companies authorized by the Federal Revenue Service.

What Octo does with cargo and customs.

Four possible deliverables. All of them run with your company's access and go through the team's review.

Integration with the Portal Único

Can write the client for the Portal Único REST API, in XML and JSON, validating each message against the published XSD before submission.

Deliverable: integration client for review

Queries within the limit

Can queue the automated Duimp queries so they do not exceed the limit of 1,000 queries per hour per user (accessed October 28, 2026).

Deliverable: query routine with rate control

Reconciled inventory

Can compare the receipt, delivery and devanning events and the CCT Importação inventory with internal records and list the differences.

Deliverable: list of differences for the team

Loading and unloading report

Can prepare the filing of the loading and unloading report in Siscomex Carga by web service, from the data your company's system already has.

Deliverable: submission routine for review and approval

Eight arms, one cargo trail.

The same Octo cycle, applied to this topic. Each arm has a narrow role; the people who approve and sign are on your team.

Discovery
Identifies the authorization

Which authorization your company holds with the Federal Revenue Service and which services it uses.
Data
Maps field to field

Each field in the company's system linked to the field in the official message, checked against the XSD.
Security
Uses the company's access

Certificate and credentials stay with the company. Octo has no access of its own.
Architecture
Chooses the service

Portal Único, CCT or Siscomex Carga, depending on the task.
Development
Writes the integration

Message assembly, XSD validation, rate control and a record of each response.
Review
Tests with the queries

Starts with the queries, which change nothing, and compares with what the team sees in the system.
Release
Publishes with your OK

Submissions only go into use after your team's approval.
Documentation
Records the version

Which version of the specification and the manual was used.

Octo does not replace the party authorized by the Federal Revenue Service. The integration runs with your company's access, and your company answers for the information.

Each task, its path.

The criteria Octo uses to pick the path. The regulation and the official system remain the reference.

Task	Path	Note
Knowing who oversees cargo	Customs offices	Law 12.815/2013, art. 24, II
Integrating with the Portal Único	REST API, XML and JSON, with XSD	Portal Único documentation
Import cargo in the waterway mode	CCT Importação: receipt, delivery, devanning and inventory	CCT API specification
Automated Duimp queries	Integre seu sistema (Integrate your system)	1,000 queries per hour, per user (accessed October 28, 2026)
Loading and unloading report	Siscomex Carga, web service	Siscomex Carga manual

From request to routine.

Three steps. Each one only makes sense once the previous one has shown results on your team.

A proposal, not a promise

What Octo does and what stays with you.

Octo prepares everything, but does not sign. The document of record stays with whoever is accountable for it.

Octo prepares

Gathers, calculates, organizes and produces the documents: spreadsheets, reports, dashboards and drafts.

Deliverable: material ready for review

Your team reviews

The licensed professional reviews what Octo delivered before signing. If something doesn't add up, it goes back to Octo with the correction.

Step: review by whoever signs

Who signs

Octo does not sign. Designs, technical reports, ART/RRT, accountability reports and any official document are still signed by the licensed professional at the company or agency: here, the professional of record and the port authority.

Signature: professional of record and port authority
