PESO QR Code & Barcode Requirements for Gas Cylinders

PESO has issued implementation guidance for the Gas Cylinders (Amendment) Rules, 2025 concerning permanent and tamper-proof barcode / QR code identification on gas cylinders and cryogenic containers. This page summarizes the requirement and explains where durable metal QR code tags may be considered as an identification solution.

What Does the PESO Requirement Say?

• The Gas Cylinders (Amendment) Rules, 2025 require permanent and tamper-proof marking at a conspicuous place on applicable cylinders and cryogenic containers.
• PESO implementation communications refer to barcode / QR code identification under the amended rules.
• Cylinders manufactured before commencement of the amendment are subject to the transition period specified in the applicable notification and PESO communications.

The PESO communication does not state that the identification carrier must be made of metal. Metal QR code tags are one engineering option where durability, mounting and long-term readability make them suitable for the cylinder application.

Metal QR Tag Options for Cylinder Identification

• Material options: Stainless steel, aluminium and titanium selected according to duty conditions.
• Laser marking: QR codes, barcodes, Data Matrix codes, serial numbers and variable data.
• Mounting: Rivet, clamp and mechanical mounting options; adhesives only where validated for the application.
• Serialization & QA: Batch data files, scan verification and integration support.

Recommended Products

• Stainless Steel QR Tags — durable general-purpose option for industrial and cylinder identification
• Aluminium QR Tags — lightweight option where the application and mounting method are suitable
• Titanium QR Tags — specialized option where titanium material properties are required
