Frequently Asked Questions About Carbon Steel IBC Totes
-
A carbon steel IBC tote is an intermediate bulk container constructed from heavy-gauge carbon steel, used for the storage and over-the-road transport of hazardous and non-hazardous industrial liquids. Unlike composite IBCs which use a plastic inner bottle, carbon steel IBC totes are fully metallic, offering higher structural strength, compatibility with a wider temperature range, and suitability for flammable and combustible liquids. Hawman carbon steel IBCs are UN31A certified and available in capacities from 250 to 3,200 litres.
-
Carbon steel IBC totes are built from mild steel and are the most economical metallic IBC option. They are suitable for lubricants, fuel oils, oilfield chemicals, water treatment reagents, and Class III flammable liquids. Stainless steel IBC totes (304L or 316L) are used for corrosion-sensitive applications, food-grade liquids, acids, caustics, and products that react with carbon steel. For general industrial, oilfield, and fuel oil applications, carbon steel IBCs offer the best combination of strength, cost, and certification compliance.
-
Hawman carbon steel IBC totes are used for lubricating oils, diesel fuel oil, grease, oilfield chemicals, injection chemicals, corrosion inhibitors, water treatment reagents, process chemicals, and Class III flammable liquids. Specific chemical compatibility depends on the product. Contact Hawman for a compatibility review for your specific fluid.
-
UN31A is the United Nations performance certification for metallic intermediate bulk containers used in the transport of hazardous materials. It confirms the carbon steel IBC tote has been tested for stacking load, drop resistance, vibration, and liquid tightness for over-the-road transport. Hawman's C and GT Series are UN31A certified for liquids up to 2.0 specific gravity, meeting Canadian Transport Commission (TC) and US DOT requirements.
-
CAN/ULC-S601-14 is a Canadian certification standard for shop-fabricated steel aboveground tanks used for the storage of flammable and combustible liquids. Hawman's C Series carbon steel IBCs carry both UN31A (for transport) and CAN/ULC-S601-14 (for stationary storage) certifications — one of the only IBC product lines in Canada to hold both. This dual certification is required for regulated flammable liquid storage at facilities subject to provincial fire codes and safety standards.
-
Hawman carbon steel IBC totes are available in a wide range of capacities. The C Series ranges from approximately 250 to 687 US gallons (951 to 2,602 litres) in both 42" × 48" and 48" × 48" footprints. The GT Series (hopper bottom for viscous products) is available in 306, 449, and 506 US gallon configurations. The CR/SR cylindrical series reaches up to 845 US gallons (3,200 litres). Custom capacities and sizes are available on request.
-
The GT Series is Hawman's purpose-built carbon steel grease and viscous liquid IBC tote. It features a 37° hopper bottom, 3" forward-facing drain, and a front pocket sump with 3" camlock fittings for direct grease pump installation. It is specifically engineered for bulk grease, heavy lubricants, viscous oilfield fluids, and other products that do not flow easily from a standard flat-bottom tote.
-
Yes. Hawman's C Series carbon steel IBC totes are certified for Class III flammable and combustible liquids under both UN31A (for transport) and CAN/ULC-S601-14 (for stationary storage). This makes them one of the most fully certified flammable liquid IBC tote options available from a Canadian manufacturer. Always confirm site-specific regulatory requirements with your local authority having jurisdiction (AHJ).
-
Hawman C Series and CR/SR Series carbon steel IBC totes are stackable up to four high when fully loaded, using standard forklift and pallet jack entry. The GT Series hopper-bottom totes are not designed for interstacking due to the angled hopper geometry. Contact Hawman for specific stacking configurations.
-
Yes. Hawman Container Services manufactures carbon steel IBC totes in Barrie, Ontario. Hawman holds ISO 9001:2015 quality management certification, CWB-certified welding (W47.1), and is an API member company. All standard and custom carbon steel IBCs are designed, fabricated, and tested in Canada.
-
Yes. Hawman's engineering and fabrication team designs and builds fully custom carbon steel IBC systems including non-standard capacities, footprints, mother tote configurations, inter-stack frames, containment basins, and integrated pump systems. Contact Hawman to discuss your custom requirements.
