Chlorine Cylinder Dimensions: The Complete 2026 Specification Guide for Industrial Buyers
Everything import managers, brand owners, and sourcing agents need to know about standard chlorine cylinder sizes, DOT compliance, OEM options, and supply-chain best practices.
If you are sourcing industrial chlorine cylinders for water treatment, chemical processing, or refrigeration applications, the first question is always: what are the standard chlorine cylinder dimensions? In 2026, the U.S. market predominantly uses 100 lb (44 kg), 150 lb (68 kg), and 2,000 lb (907 kg) ton containers, each with specific diameter, height, tare weight, and valve configurations. This guide covers every dimensional detail you need to plan logistics, negotiate pricing, and ensure DOT/ISO compliance with your supplier.
Why Chlorine Cylinder Dimensions Matter for Your Supply Chain
Chlorine is classified as a Division 2.3 toxic gas under U.S. DOT regulations. Every dimension deviation — from overall height to valve outlet thread — can cause shipping rejections, port delays, or safety violations. In our 10+ years of supplying high-pressure steel cylinders and specialty gases to North American importers, we’ve seen buyers waste an average of 18–24 days when cylinder dimensions do not match their filling station or container footprint.
Below we address the five most common procurement pain points we hear from import managers and wholesale buyers:
- Incompatible valve connections — U.S. chlorine cylinders require CGA 820 or CGA 660 connections; Chinese factories must match exactly.
- Container optimization — 20 ft and 40 ft container palletization depends on precise cylinder outer diameter and stacking height.
- Regulatory non-compliance — DOT-3A, DOT-3AA, or ISO 9809-1 markings must be legible and period-tested.
- Hidden tare-weight variation — Average tare weight affects declared net quantity for customs and freight.
- Long lead times for OEM dimensions — Non-standard sizes can delay delivery from 45 to 90 days.
Standard Chlorine Cylinder Dimensions (U.S. & International Standards)
The tables below reflect the most common chlorine cylinder sizes traded globally. All data complies with DOT-3A/3AA and ISO 9809-1 specifications. Note: actual dimensions may vary by manufacturer; always request a dimensional drawing for order confirmation.
| Cylinder Capacity | Service Pressure (psi) | Outer Diameter (in) | Overall Height (in) | Tare Weight (lb) | Valve Connection | DOT Specification |
|---|---|---|---|---|---|---|
| 100 lb (44 kg) | 840 | 10.0 | 51.0 | 78–82 | CGA 820 | DOT-3AA |
| 150 lb (68 kg) | 840 | 12.0 | 56.5 | 115–125 | CGA 820 | DOT-3AA |
| 2,000 lb Ton Container | 500 | 30.0 | 79.5 | 1,350–1,450 | CGA 660 | DOT-3A |
| 500 kg (1,100 lb) | 525 | 24.0 | 65.0 | 660–710 | CGA 820 / CGA 660 | DOT-3AA |
| 50 lb (23 kg) | 840 | 8.5 | 42.0 | 42–48 | CGA 820 | DOT-3AA |

Compliance & Certification Requirements for U.S. Importers
Every chlorine cylinder imported into the United States must meet DOT-3A or DOT-3AA specifications and pass a 5-year hydrostatic retest (DOT 49 CFR 180.205). In addition to dimensional compliance, the following certifications are mandatory for market access:
ISO 9001:2025
Quality management system for manufacturing process consistency.
DOT-3AA / ISO 9809-1
Standard for seamless steel cylinders with specified minimum wall thickness.
CGA V-1
Standard for cylinder valve connections, including CGA 820 and CGA 660.
UN / IMDG
UN markings for international transport; IMDG Code compliance for sea freight.
At Zhuzhou XingYe Chemical, every high-pressure steel cylinder we supply includes COA, MSDS, ECM documentation, and applicable food-grade or industrial-grade certifications. We also assist buyers with DOT re-certification paperwork if cylinders will be re-exported.
OEM/ODM Customization: Cylinder Dimensions Tailored to Your Operation
Many import managers and brand owners need cylinders that deviate from standard sizes to fit existing filling machinery, storage racks, or container layouts. Our factory supports OEM/ODM customization with the following capabilities:
| Customization Option | Range / Details | Typical Lead Time |
|---|---|---|
| Outer diameter (OD) | 7.0 in to 36.0 in | 30–45 days |
| Overall height (OH) | 30 in to 96 in | 30–45 days |
| Valve connection type | CGA 820, CGA 660, BS 341, DIN 477 | 20–30 days |
| Tare weight tolerance | ±2 lb for small cylinders; ±5 lb for ton containers | 25–40 days |
| Surface finish / paint | Custom RAL colors, anti-corrosion epoxy, branding | 15–25 days |
| Stamping / labeling | DOT/ISO marks, barcode, QR, serial number | 10–20 days |

Application Scenarios & Cylinder Selection Guide
Choosing the right chlorine cylinder dimensions depends on your end-use case. Below are the three most common procurement profiles we encounter:
🏰 Municipal Water Treatment
Ideal cylinder: 150 lb or 2,000 lb ton container.
Why: High-volume continuous feed requires fewer change-outs. Ton containers provide 30–45 days of supply for a 10 MGD plant. Ensure CGA 820 valve compatibility with chlorinator.
🏭 Pool & Spa Chemical Distribution
Ideal cylinder: 100 lb or 50 lb.
Why: Weight limits for service technicians; 100 lb cylinders can be handled by one person with a dolly. Palletize 24 units per layer for efficient warehousing.
💡 Industrial Chemical Processing
Ideal cylinder: 500 kg or 2,000 lb ton container.
Why: Batch processing requires steady pressure output. Larger cylinders reduce connection frequency and improve safety. Custom OD available to fit existing rack systems.
