Whether you are a refrigeration engineer sourcing ammonia for a cold storage plant, a textile mill procuring liquefied ammonia for dyeing operations, or a laboratory needing a small quantity for analytical work, understanding ammonia cylinder and tonner sizes, specifications, and pricing in India is essential for making the right procurement decision. The Indian ammonia cylinder market is regulated by multiple standards bodies, and buyers who understand the system can source more efficiently, comply more easily, and manage their supply chain with confidence.
Ammoniagas has supplied ammonia cylinders, tonners, and bulk quantities to industrial customers across India for decades. This guide draws on that experience to provide a practical, accurate buyer’s reference for the Indian market. For current pricing or to place an order, visit our quote request page.
1. Standard Ammonia Cylinder Sizes in India
Ammonia cylinders in India are available in three standard sizes based on the fill weight (the net weight of ammonia the cylinder contains when full). These sizes are standardised under BIS specifications and are the forms in which anhydrous ammonia is distributed to industrial users who do not have bulk storage facilities.
| Cylinder Type | Fill Weight (NH3) | Water Capacity | Tare Weight (approx.) | Gross Weight (approx.) |
|---|---|---|---|---|
| Small Cylinder | 47 kg | ~72 litres | 55–65 kg | ~110 kg |
| Medium Cylinder | 100 kg | ~150 litres | 90–110 kg | ~200 kg |
| Large Cylinder | 150 kg | ~230 litres | 130–150 kg | ~290 kg |
All cylinders are oriented vertically during storage and use. The fill ratio (the ratio of liquid ammonia to water capacity) is controlled at approximately 0.53–0.55 to allow for thermal expansion — cylinders are never filled completely, as liquid ammonia expands significantly with temperature and an overfilled cylinder can fail catastrophically.
The fill weight stamped on an ammonia cylinder refers to the maximum permitted weight of ammonia the cylinder may contain, not a description of the cylinder size itself. A cylinder with a 100 kg fill rating may be physically smaller or larger than another design with the same rating, depending on wall thickness and design pressure. Always refer to the cylinder’s official certification documentation for all relevant parameters.
2. Ammonia Tonner Sizes and Specifications
Ammonia tonners (ton containers or ton cylinders) are the step up from cylinders in India’s ammonia supply infrastructure. These are horizontal, cylindrical pressure vessels designed for permanent or semi-permanent installation at the user’s premises. They are filled in situ by tanker delivery and connected directly to the user’s process system via valves and pipework.
| Tonner Specification | Standard Details |
|---|---|
| Standard Fill Capacity | 900 kg (Indian market standard; some designs 1,000 kg) |
| Water Capacity (WC) | ~1,700 litres |
| Design Pressure | 25–28 bar (varies by standard and operating temperature) |
| Test Pressure | Typically 1.5x design pressure per BIS/PESO requirements |
| Shell Material | Carbon steel (IS 2062 or equivalent) |
| Valve Configuration | Two inlet/outlet valves + safety relief valve + liquid level indicator |
| Inspection Interval | Every 5 years hydrostatic testing; annual visual inspection |
| Connection Standard | IS 8552 CGA-660 equivalent valve and outlet connections |
Ammoniagas supplies tonners through its own cylinder maintenance and management service. Our cylinder and tonner maintenance programme includes regular inspection, valve servicing, and coordination with PESO-approved testing stations for statutory hydrostatic testing. This takes the administrative burden of vessel compliance off the customer’s operations team.
3. Cylinder vs Tonner: Which Is Right for Your Operation?
| Factor | Cylinders (47/100/150 kg) | Tonner (900 kg) |
|---|---|---|
| Monthly consumption threshold | Best for under 100 kg/month | Economical from 200 kg/month and above |
| Capital investment | Low — no permanent infrastructure needed | Medium — tonner purchase/lease + installation pad required |
| Per-kg cost | Higher (logistics cost per kg is greater) | Lower (bulk filling is more cost-efficient) |
| Space requirement | Small — cylinder cage or storage area | Larger — outdoor pad, safety exclusion zone, tanker access |
| PESO requirements | Storage licence for quantities above exempt threshold | Always requires PESO licence and detailed safety plan |
| Supply disruption risk | Higher — dependent on cylinder delivery schedule | Lower — larger buffer stock in tonner |
| Cylinder testing responsibility | Cylinder owner (usually the gas supplier) | Tonner owner — customer responsible if owned outright |

4. Ammonia Cylinder Grades and Purity Levels
Anhydrous ammonia supplied in cylinders and tonners in India is available in multiple purity grades, each suited to specific applications. The grade specified at the time of order determines the chemical analysis certification and price.
| Grade | Typical Purity | Water Content (max) | Primary Applications |
|---|---|---|---|
| Industrial Grade | 99.5% min | 0.5% | Textile processing, water treatment, general chemical industry |
| Refrigeration Grade | 99.95% min | 0.02% | Cold storage, ice plants, process refrigeration |
| Electronic / Semiconductor Grade | 99.999% min (5N) | 0.1 ppm | Semiconductor manufacturing, MOCVD, laboratory analysis |
| Agricultural Grade | 99.5% min | 0.5% | Direct injection fertilisation (limited in India) |
Most industrial users in India procure industrial grade for chemical processing and refrigeration grade for cold storage applications. Ammoniagas technical services can advise on the appropriate grade for your specific application and provide the corresponding Certificate of Analysis for quality verification.
5. Ammonia Pricing Guide for Indian Buyers
Ammonia prices in India are market-driven and fluctuate based on several interconnected factors. Understanding these drivers helps procurement managers anticipate price movements and structure purchasing agreements effectively.
Key Price Drivers
Natural gas prices are the most significant cost input, as the Haber-Bosch process that produces ammonia is natural gas-intensive (approximately 28–35 GJ of energy per MT of ammonia). When domestic gas prices rise — as they do when global LNG markets tighten — ammonia prices follow within 4–8 weeks. Secondary factors include naphtha prices (used by some Indian ammonia producers as a feedstock alternative), import parity (global ammonia prices affect Indian pricing when imports compete with domestic production), and seasonal demand patterns (demand peaks during the fertiliser application seasons and before the summer cooling season).
Indicative Price Ranges (2025-2026)
| Product Format | Grade | Indicative Price Range (INR) | Notes |
|---|---|---|---|
| 47 kg cylinder | Industrial | 550–850 per cylinder | Ex-works; logistics additional |
| 100 kg cylinder | Industrial | 1,100–1,700 per cylinder | Volume discounts available |
| 150 kg cylinder | Industrial | 1,600–2,500 per cylinder | Volume discounts available |
| Tonner (900 kg) | Industrial | 15,000–25,000 per fill | Tanker delivery; depends on distance |
| Bulk tanker | Industrial | 12,000–18,000 per MT | Minimum order typically 10 MT |
| Refrigeration grade premium | Refrigeration | 10–20% above industrial | Higher purity specification |
Optimising Your Procurement Cost
The most effective way to reduce per-kg ammonia cost is to increase the quantity ordered per delivery. Moving from 47 kg cylinders to 150 kg cylinders reduces the logistics cost per kg significantly. Moving to tonner supply reduces it further. For high-volume users, bulk tanker delivery offers the lowest per-kg cost of any supply format. Ammoniagas can conduct a supply cost analysis for your specific consumption profile and location to identify the most cost-effective format.
6. BIS and PESO Specifications for Ammonia Vessels
All ammonia pressure vessels used in India — cylinders, tonners, and bulk storage tanks — must comply with specific Indian Standards and be manufactured, tested, and operated under the oversight of the Petroleum and Explosives Safety Organisation (PESO), the statutory body under the Ministry of Commerce and Industry responsible for the regulation of explosives, petroleum, and compressed gases in India.
Relevant Indian Standards
IS 7285 specifies the requirements for seamless gas cylinders for permanent and liquefied gases. IS 5765 covers valve specifications for gas cylinders. IS 5116 specifies the requirements for anhydrous ammonia (industrial grade). IS 2062 specifies the steel used in pressure vessel construction. All cylinders must carry a BIS certification mark confirming compliance with these standards, as well as the PESO hydrostatic test date stamp indicating when the vessel was last tested and when its next test is due.
7. Hydrostatic Testing and Cylinder Maintenance
Under the Gas Cylinders Rules 2016, ammonia cylinders must undergo periodic hydrostatic pressure testing at intervals not exceeding 5 years. During this test, the cylinder is filled with water to its water capacity and pressurised to 1.5x its design pressure. The cylinder is examined for expansion (permanent volumetric increase), visible defects, and leakage. Cylinders that fail the test or exceed their permitted expansion limits are condemned and must be removed from service.
Ammoniagas manages the hydrostatic testing cycle for all cylinders in its supply fleet. Customers using our cylinders on a loan basis do not need to track or arrange testing — our operations team manages this automatically. Customers who own their own cylinders can use our cylinder maintenance service to arrange testing coordination with PESO-approved stations.
Using a cylinder that is overdue for hydrostatic testing is a regulatory violation under the Gas Cylinders Rules 2016. Beyond the legal risk, an untested cylinder may have developed wall thinning or corrosion that compromises its structural integrity. Always verify the test date stamped on the cylinder neck ring before putting it into service.
8. Storage Requirements and PESO Licensing
The storage of filled ammonia cylinders in India requires compliance with the Gas Cylinders Rules 2016. The key requirements are directly relevant to any industrial user maintaining a cylinder inventory on their premises.
Basic Storage Rules for Cylinders
Cylinders must be stored vertically with valve caps or guards fitted. Filled and empty cylinders must be stored in separate, clearly marked areas. Storage must be in a well-ventilated area, preferably open-sided, away from heat sources and incompatible materials (acids, oxidisers, halogenated compounds). A minimum 3-metre separation from any flammable material or ignition source is required. The storage area must be clearly signed with appropriate hazard warning signs.
PESO Licence Requirements
Storage of ammonia cylinders above the exempt quantity under the Gas Cylinders Rules 2016 requires a formal storage licence from PESO. The exempt quantity for class P2 gases (which includes ammonia) is typically 4 cylinders totalling not more than 125 kg. Any storage above this requires a licence application, site inspection, and ongoing compliance. Tonner storage always requires a licence regardless of quantity.
9. Buyer’s Selection Guide
Use the following decision framework to identify the optimal supply format for your ammonia procurement needs.
| Monthly Consumption | Recommended Format | Key Consideration |
|---|---|---|
| Under 50 kg | 47 kg cylinders | Simplest supply; no PESO licence needed for 1–4 cylinders |
| 50–200 kg | 100–150 kg cylinders or multiple 47 kg | PESO storage licence likely required; evaluate cylinder loan vs ownership |
| 200–900 kg | Single tonner | Significant per-kg cost saving; requires PESO licence and installation |
| 900 kg to 5 MT | Multiple tonners or small bulk tank | Multiple tonner setup or a small ground-mounted bullet tank; PESO detailed assessment |
| Above 5 MT | Bulk storage with tanker supply | Lowest per-kg cost; significant infrastructure investment; full MSIHC Rules compliance |
10. Transport and Delivery Compliance
The transport of ammonia cylinders and tonners on Indian roads is regulated under the Motor Vehicles Act and the Hazardous Materials Rules. Only vehicles with the appropriate endorsement for hazardous goods transport may carry filled ammonia cylinders. The driver must hold a valid Hazardous Goods transport licence. The vehicle must display the appropriate Hazchem placard for ammonia (1076) and carry a written emergency action card.
Ammoniagas operates its own transport fleet and manages all regulatory compliance for cylinder and tonner delivery. Our vehicles are equipped with appropriate safety equipment, and our drivers are trained in hazardous materials handling. We maintain full documentation for all deliveries, which customers may request for their own regulatory compliance records. Learn more about our materials transportation services.
