What is the Difference Between PESO Type Approval and Import Permission?

PESO issues two distinct instruments that affect importers. Type Approval, which certifies that a product design meets Indian safety standards and Import Permission (NOC), which authorises a specific consignment to enter India. Both may be required simultaneously. Holding one without the other does not satisfy PESO compliance and will result in Customs detention.

What is the difference between type approval and import permission?

The Petroleum and Explosives Safety Organisation (PESO) administers two instruments that importers of regulated goods must understand and treat as separate obligations. The first is Type Approval, a technical certification that the design, construction and specifications of a product meet the safety requirements prescribed under the relevant Indian statute or standard. The second is the Import Permission No Objection Certificate (NOC), a transactional authorisation that permits a specific quantity of a specific product to be imported through a specified port during a specified period.

Type Approval is a product-level clearance that certifies the product design and once PESO grants Type Approval for a product model it applies to all units manufactured to that specification. Type Approval does not expire in the same way a transactional permission does and remains valid as long as the product design remains unchanged. Any modification to the product design, materials or manufacturing process may invalidate the existing Type Approval and require fresh assessment. PESO issues Type Approvals for products such as gas cylinders, pressure vessels and certain explosive articles where the design must be verified against Indian safety standards before commercial import is permitted.

Import Permission NOC is a consignment-level clearance that authorises a particular import transaction for a defined quantity of an approved product, from a named supplier, entering through a named port within a defined validity window. Even if a product already holds PESO Type Approval, each import consignment requires its own NOC and is not a substitute for it in the Customs examination process.

The sequential relationship

The relationship between the two instruments is sequential for many product categories. PESO will not issue Import Permission for a product that has not first received Type Approval where it is applicable. An importer who attempts to secure a NOC for a product that has not yet gone through the Type Approval process will find the NOC application rejected or placed on hold pending completion of that procedure.

Implications for businesses

Foreign manufacturers who export gas cylinders, pressure vessels or other design-tested products to India must engage with the Type Approval process before their Indian customers can lawfully import the product. The Type Approval assessment often requires the foreign manufacturer to submit technical drawings, material certifications and test reports to PESO. A foreign manufacturer who has not completed this process cannot simply receive a purchase order from an Indian buyer and ship.

Indian importers who deal in product categories where Type Approval is mandatory face a two-stage pre-import obligation. They must first confirm that their supplier's product holds current PESO Type Approval. They must then apply for and receive the Import Permission NOC for each consignment before authorising shipment.

Any supply-side change to the product after Type Approval is granted invalidates it and fresh assessment may be required before the next shipment.

How type approval and import permission compliance works

The Type Approval process begins with the importer or foreign manufacturer submitting an application to PESO's headquarters in Nagpur. The application must include complete technical specifications, drawings, material specifications, pressure ratings and valve and fitting details for cylinders and vessels or design and composition details for explosive articles. PESO reviews these specifications against the applicable Indian standard or safety requirement under the relevant statute. PESO may require physical samples of the product to be submitted for testing at a recognised testing laboratory before granting Type Approval.

The importer applies for the Import Permission NOC for each consignment once Type Approval is secured. The NOC application includes the Type Approval certificate number, the quantity to be imported, the supplier details, the port of entry and the intended use or end-user details. The NOC must be in the importer's possession before the consignment departs the port of origin to be presented to Customs at the time of clearance, together with the Type Approval certificate, Bill of Lading, commercial invoice, packing list and other standard documents, completes the PESO compliance element of the Customs examination. Any mismatch in quantity or port of entry or referencing an outdated Type Approval is grounds for Customs detention pending clarification or re-issuance.

Legality and risks

The statutory basis for both Type Approval and Import Permission requirements is found in the statutes PESO administers. The Gas Cylinders Rules, 2016 and the Static and Mobile Pressure Vessels (Unfired) Rules, 2016 require that equipment meet design standards before import. The Explosives Act, 1884 and the Petroleum Act, 1934 require authorisation before import. Importing without satisfying either requirement is an offence under the applicable statute.

A consignment that lacks either a valid Type Approval or a valid NOC will be detained by Customs pending PESO review. During detention, demurrage and storage charges accumulate without pause. If the goods are found to be unapproved in design, re-export may be ordered. The detention charges and re-export costs for a medium-sized consignment of rejected cylinders can reach several lakh rupees within two weeks.

Word of counsel

Importers should request a current copy of the Type Approval certificate from their foreign supplier before every order cycle. A product that held PESO Type Approval two years ago may not hold it today, because the manufacturer changed a material, adjusted a valve specification or the approval was time-limited and has since lapsed. The assumption of Type Approval continuity should be avoided.

CHAs who handle gas cylinder, pressure vessel or explosives article consignments should check the PESO Type Approval certificate for the product model and the PESO NOC for the specific consignment at the pre-arrival stage.
