NR-13-Ready Air Compressors for Import into Brazil
Brazil’s NR-13 governs compressor air receivers that fall within its pressure-vessel scope. Compliance documentation includes a technical dossier, identification plate, vessel category, and inspection records. EMAX confirms available documentation for each model on request; importers should also confirm applicable NR-12 machine-safety and INMETRO requirements before shipment.
In Brazil the compressor’s air receiver is a vaso de pressão, and NR-13 governs it: a prontuário, an identification plate, a category, and periodic inspection. Get the documentation wrong and the vessel cannot be regularised — the unit stalls and the project with it.
The air receiver is a pressure vessel — that puts it under NR-13
NR-13 (Caldeiras, Vasos de Pressão, Tubulações e Tanques Metálicos de Armazenamento) is Brazil’s regulatory standard for boilers and pressure vessels. A compressor’s air receiver is a vaso de pressão, and when it meets NR-13’s scope criteria it is subject to the standard: the vessel needs a prontuário (its technical dossier), an identification plate, an assigned category, and a regime of periodic inspection by a qualified professional.
NR-13 is the Brazilian counterpart to Australia’s AS 1210 — the same idea, a different jurisdiction. For an importer, it is the document trail that lets the vessel be legally installed and operated, not a formality to settle after the container lands.
No prontuário, no plate — the vessel cannot be regularised
Without an NR-13 prontuário and identification plate, the pressure vessel cannot be regularised in Brazil. That exposes the importer to autuação (citation) and to a parada — the unit being stopped — with the commercial fallout landing on whoever sold it.
This is exactly where an importer wins or loses time at the port. Equipment that arrives compliance-ready clears and installs; equipment that does not becomes a port trap. EMAX positions its export documentation to keep importers out of that trap.
- NR-13 requires a prontuário, identification plate, category, and periodic inspection.
- A non-regularised vessel risks citation and being stopped in service.
- Compliance-ready documentation is the difference between clearing the port and being held at it.
Documentation built for the importer’s compliance trail
EMAX builds its pressure vessels to a registrable standard and works with Brazilian importers on the documentation NR-13 expects. The precise NR-13 deliverables EMAX issues per model — prontuário, identification plate, and related technical records — are confirmed with the team for the units you intend to import.
| Framework | NR-13 (vasos de pressão) |

| Issuing authority | Model-specific documentation; confirm with EMAX |
| Registration number | Confirm per model with EMAX |
| Scope | Air receivers within the NR-13 pressure-vessel scope |
| EMAX deliverables per model | [a confirmar com a EMAX] |
| Import gate | INMETRO (Portaria 120/2021) |

NR-12 covers the machine, not the vessel
NR-12 (Segurança no Trabalho em Máquinas e Equipamentos) is a separate, complementary requirement: it governs the safety devices, guarding, and protections on the machine itself. NR-13 covers the pressure vessel; NR-12 covers the equipment around it. A compressor entering a Brazilian workplace is expected to satisfy both — which is why we treat NR-12 as the machine-safety companion to the NR-13 vessel framework, not a substitute for it.
INMETRO is the gate at the border
For serially manufactured pressure vessels, INMETRO conformity assessment (under the SBAC framework, with Portaria 120/2021 relevant to pressure vessels) may apply — confirm the model-level scope before shipment. Where it applies, it is required at customs clearance, so treating it together with NR-13 — handled before departure rather than after arrival — is what keeps delivery predictable.

Pressure-vessel families
The screw and piston lines carry the certified-vessel discipline that an NR-13 compliance trail starts from. Each detail page has the specs and downloads a procurement team reviews before they commit.
Rotary Screw
PM VSD and fixed-speed screw compressors with certified air receivers — the core industrial range for Brazil.
Piston
Oil-lubricated, oil-free, and engine-driven piston compressors — vessel documentation confirmed per model on request.

NR-13 questions importers ask
- Is a compressor’s air receiver covered by NR-13?
- Yes. The air receiver is a vaso de pressão, so it falls under NR-13 — requiring a prontuário, an identification plate, an assigned category, and periodic inspection by a qualified professional.
- What is the difference between NR-13 and NR-12?
- NR-13 governs the pressure vessel (the air receiver); NR-12 governs machine safety — guarding and protective devices on the equipment itself. A compressor entering a Brazilian workplace is expected to meet both.
- Where does INMETRO fit in?
- INMETRO conformity, framed by Portaria 120/2021 for pressure vessels, is the access gate at the border. It is where a shipment is cleared or held, so it belongs in the same compliance trail as NR-13 — handled before departure.
- What NR-13 documentation does EMAX provide?
- EMAX builds to a registrable standard and supports importers with the NR-13 documentation trail. The exact deliverables per model are confirmed with the team — request the documentation pack for the specific units you plan to import.
