Introduction

A few months back, an industrial equipment company from Europe approached Diligence Certifications when they faced problems delivering their pressure vessels to India. They had already performed all the quality checks on their products as per international standards and thought that their foreign manufacturing approvals would be enough for India.

As part of our compliance assessment, our team found out that the imported industrial equipment needed PESO import approval before they could be put to use commercially in India. They had already shipped their products but were unsure about customs clearance and installation timelines due to lack of regulatory approval.

Such is the case with most international suppliers and Indian importers. Most organizations are concerned about quality and delivery of their products to customers but often fail to consider country-specific safety approvals.

The PESO Import Approval process becomes crucial for organizations that import regulated products like gas cylinders, pressure vessels, petroleum-based equipment, hazardous material handling systems, etc.

We at Diligence Certifications can help you with the process of PESO import approval.

What is PESO Import Approval?

PESO Import Approval is the regulatory approval granted by the Petroleum and Explosives Safety Organisation for importing particular items under the jurisdiction of petroleum, explosives, compressed gas, and hazardous materials in India.

This approval indicates that the imported items satisfy the Indian safety regulations and are legal to use, store, transport, or operate in India.

PESO falls under the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce & Industry, Government of India. It is responsible for regulating the safety aspects of:

• Petroleum products
• Explosives
• Compressed gases
• Gas cylinders
• Pressure vessels
• Cryogenic containers
• Hazardous chemical storage systems

Unlike normal commercial imports, regulated products require additional evaluation because safety failures can create serious risks to people, property, and the environment.

A product manufactured outside India may meet international standards, but it still needs verification against Indian regulatory requirements.

Difference Between Normal Import Approval and PESO Import Approval

Many businesses confuse general import procedures with PESO requirements.

A normal import process mainly focuses on customs, taxation, and trade documentation. However, PESO Import Approval focuses on safety compliance.

Normal Import Process	PESO Import Approval
Related to commercial entry of goods	Related to safety-regulated products
Managed through customs procedures	Managed by PESO regulations
Focuses on trade compliance	Focuses on technical safety compliance
Applies to general products	Applies to hazardous and controlled products

For regulated industries, completing customs procedures alone does not mean the product is approved for operation.
