Introduction

An importer of gas equipment approached us in our compliance department as an import cargo of industrial gas cylinders was detained in an Indian port due to non-compliance with certain important requirements. Although all commercial requirements had been met by the supplier, the process of customs clearance could not begin owing to the non-compliance with one of the important conditions - PESO Approval for Industrial Gas Cylinders.

Until the additional documentation and verification of the compliance requirements was conducted, the cargo lay in the port facing storage costs as well as delivery delays. Moreover, the importer ran the risk of losing a long term client as a result of untimely delivery.

Such cases happen often enough. Industrial gas cylinders are used widely in the following industries: manufacturing, health care, oil and gas, welding, chemical industry, pharmaceutics, and engineering. Being gas vessels which store gases under high pressure, they have strict safety requirements to be complied with prior to manufacture, import, sale, and use of the cylinders in India.

This is where PESO Approval for Industrial Gas Cylinders becomes crucial since it ensures that cylinders comply with relevant technical, safety and quality requirements.

What is PESO Approval for Industrial Gas Cylinders?

PESO Approval for Industrial Gas Cylinders is an approval by the Petroleum and Explosives Safety Organisation (PESO), which is a body functioning under the Department for Promotion of Industry and Internal Trade (DPIIT) in the Government of India.

The purpose of the PESO approval is to ensure that the industrial gas cylinders meet certain standards regarding their design, manufacture, testing, and safety before entering into the Indian market.

Use of industrial gas cylinders is accompanied by the storage of gases such as oxygen, nitrogen, argon, helium, hydrogen, carbon dioxide, and others. Since the gases are stored under pressure, any defect during their manufacture may cause hazards.

Therefore, during their approval, PESO considers various technical specifications, which are:

• Product design
• Material specifications
• Manufacturing quality
• Pressure resistance
• Safety performance
• Inspection procedures
• Quality management systems

The approval process ensures that industrial gas cylinders are capable of performing safely under their intended operating conditions.

---

Why is PESO Approval Important?

Industrial cylinders are created to hold compressed gases at high pressures. Unlike other containers, industrial gas cylinders have to endure tough operating conditions all through their life cycles.

The absence of appropriate engineering controls and quality controls during cylinder production can lead to structural defects, leaks, and other pressure-related problems.

PESO approval reduces such risks because the PESO-approved cylinders meet certain criteria, including:

• Engineered according to recognised engineering standards.
• Made from approved raw materials.
• Passed obligatory tests for safety.
• Produced under quality control systems.
• Compliance with Indian regulations.
• Regulatory approval is beneficial for importers and suppliers of cylinders since it increases their reputation among industrial clients, government bodies, and procurement agencies, who value compliance.
• Large buyers tend to check statutory compliance before considering new suppliers.
