Common questions about Precision IBC’s line of tanks
Most liquids with a packaging group of II or III, provided the shipper has ensured chemical compatibility with the wetted areas of the container and references the 49 CFR for special provisions listed under that specific chemical’s MSDS.
Precision IBC stainless steel tanks are rated to a 1.9 specific gravity. A tank with a specific gravity of 1.9 can hold a liquid up to 15.75 pounds per gallon.
Our tanks are not to be pressurized. They are all tested to 3 PSIG at the time of manufacture. An inert gas blanket can be used if the pressure applied is ½ lb. or less.
Precision IBC warrants all rental tanks during the rental contract period and will replace any tank proven to be defective in material or workmanship. Precision IBC also warrants to the purchaser any new stainless steel tank proven to be defective in material or workmanship within 3 years from date of original invoice.
There is a “grandfather” clause in the federal regulations. Per 49 CFR 173.32 (d), use of a Specification 57 tank is authorized only for a tank constructed before October 1, 1996.
Specification 57 tanks can only be used for transporting within North America.
Per 49 CFR 173.32(e)(1)(ii), federal regulations state all UN Specification IBCs should be pressure tested at least once every 2.5 years. All units manufactured with the UN marking also need a thickness test every 5 years.
The date of the most recent periodic retest must be marked on the tank on or near the metal serial number plate, 49 CFR 173.32(e)(3). Download our tank retest information.
The owner or the lessee of the tank must retain a written record indicating the date and results of all required tests and the name and address of the testing entity until the next retest has been satisfactorily completed and recorded per 49 CFR 173.32(e)(4).
An IBC may not be filled and offered for transportation if the inspection period has expired. This requirement does not apply to any IBC filled prior to the retest or inspection due date. 49CFR173.35 (a)
Each IBC is weighed by the manufacturer and stamped on the serial number plate on the front of the IBC.

350 gallon IBCs – 48 in a standard 48′ trailer.
350 gallon IBCs – 52 in a standard 53′ trailer.
550 gallon IBCs – 24 in a standard 48′ trailer.
550 gallon IBCs – 26 in a standard 53′ trailer.
1 gallon = 3.785 liters.
1 liter = .2642 gallons.
Example: 350 gallon IBC x 3.785 liter = 1324.75 liters.
Example: 1000 liters = How many gallons? 1000 x .2642 gallon = 264.20 gallons.
