Food-Grade IBC Tank Requirements Explained
Everything you need to know about certifications and requirements for using IBC containers in food and beverage applications.

Using IBC tanks for food and beverage storage requires strict adherence to regulatory requirements. This guide explains what makes an IBC tank "food-grade" and how to ensure compliance with FDA and other food safety regulations.
What Makes an IBC Tank Food-Grade?
A food-grade IBC tank must meet specific criteria related to materials, construction, history, and certification. Simply cleaning a used industrial tank does not make it food-grade.
Important
Once an IBC tank has been used for non-food products (chemicals, oils, etc.), it can never be recertified for food use, regardless of cleaning methods.
FDA Requirements
Material Standards
The FDA requires that all food-contact surfaces be made from materials that are:
- Non-toxic and non-reactive with food products
- Non-absorbent and non-porous
- Resistant to corrosion and degradation
- Free from substances that could migrate into food
Most food-grade IBC tanks use High-Density Polyethylene (HDPE) that meets FDA 21 CFR 177.1520 requirements for food contact.
Key Certifications
FDA 21 CFR
Code of Federal Regulations governing food-contact materials. Look for compliance with sections 177.1520 (polyethylene) and 177.1640 (polystyrene).
3-A Sanitary Standards
Industry standards for equipment used in dairy and food processing. Ensures easy cleaning and sanitation.
NSF International
Independent certification for food safety. NSF/ANSI 2 certification covers food equipment.
UN/DOT Ratings
While not food-specific, UN certification indicates the tank meets construction and safety standards.
Product History Requirements
For used food-grade IBC tanks, documentation of previous contents is critical:
Acceptable Previous Contents
- • Fruit juices and concentrates
- • Vegetable oils (food-grade)
- • Syrups and sweeteners
- • Wine and spirits
- • Dairy products
- • Food-grade glycerin
- • Edible oils
- • Purified water
Never Acceptable Previous Contents
- • Industrial chemicals
- • Petroleum products
- • Pesticides/herbicides
- • Non-food grade oils
- • Paints or solvents
- • Unknown substances
- • Hazardous materials
- • Pharmaceutical waste
Cleaning and Sanitation
Professional Reconditioning Process
- Inspection: Visual and documentation review of previous contents
- Pre-rinse: Remove residual product with appropriate temperature water
- Detergent wash: Food-grade cleaning agents at specified concentrations
- Rinse: Complete removal of cleaning agents
- Sanitization: FDA-approved sanitizers or heat treatment
- Final rinse: Potable water to remove sanitizer residue
- Inspection: Visual verification and testing
- Documentation: Certificate of cleaning issued
Documentation You Should Receive
When purchasing food-grade IBC tanks, request the following documentation:
- Certificate of ConformanceConfirms FDA compliance and material specifications
- Product History DocumentationRecord of previous contents (for used tanks)
- Cleaning CertificateDetails of reconditioning process and date
- Material Safety DataHDPE specification and FDA compliance reference
Best Practices for Food Industry
- Purchase only from reputable suppliers with documented quality programs
- Maintain your own inspection and cleaning records
- Implement a first-in, first-out (FIFO) rotation system
- Store tanks in clean, protected environments
- Conduct regular inspections for damage or contamination
- Never mix food-grade and non-food-grade tanks in storage
- Keep all documentation for audit purposes
Conclusion
Food-grade IBC tanks are essential for safe food and beverage storage, but compliance requires attention to materials, history, certification, and documentation. Working with a knowledgeable supplier ensures you get properly certified tanks with full traceability.
