FIBC Export Certification Guide: UN Dangerous Goods, Anti-Static, and Food-Grade Compliance

UN testing covers drop test, stacking test, lifting tensile test, tear test, permeability test, and leak-proof test. The certificate must be issued by a third-party certification body; each batch or model requires inspection. The bag body must be printed with the UN mark, code, maximum load, and safety factor. UN-certified bags are frequently combined with anti-static Type C/D for combustible powder and hazardous chemical applications.

3. Anti-Static FIBC—IEC 61340-4-4 Four-Type Classification

In combustible dust or flammable solvent vapor environments, static buildup on an FIBC can cause an explosion. IEC 61340-4-4 classifies FIBCs into four types—A, B, C, and D—by static protection capability. This is also the general classification of the FIBCA (Flexible Intermediate Bulk Container Association).

Food ingredient exports impose the strictest compliance requirements on bulk bags. Different export markets have different regulatory systems.

Testing items: overall migration, specific substance migration, heavy metals, PFAS (mandatory under PPWR), odor, and precipitation.

System certifications (not mandatory but commonly required by customers): FSSC22000, BRC Packaging, or IFS Food Packaging.

Documents: DoC (Declaration of Compliance) and batch migration test report.

Universal Food-Grade Requirements

• Raw material: food-grade PP pellets; recycled material for direct food contact requires strict migration assessment—many customers do not accept PCR recycled material for direct food contact.

• Sewing thread, ink, and liner film must all be food-contact compliant.

• Production workshop requires cleanroom controls to avoid cross-contamination.

• Bag marking must indicate "food contact use."

5. Other Common Additional Tests and Certifications

UV aging: ISO 21898:2024 1,500-hour UV aging test—essential for bulk bags storing grain and mineral powder outdoors.

Safety factor: standard non-hazardous FIBC 5:1; UN dangerous goods bags follow the corresponding category requirements.

REACH (EU): SVHC (Substances of Very High Concern) list—chemical FIBC customers frequently require SVHC testing.

Chemical FIBC customers frequently require REACH SVHC testing.

7. HAOSEN's Support for FIBC Certification Compliance

Certification compliance involves full-chain matching of equipment, materials, processes, and documents. Since 2008, HAOSEN has focused on FIBC bulk bag equipment and complete production line delivery, serving customers in more than 25 countries. We provide Turnkey project support from raw material formula to finished products, workshop layout design, and on-site training. We support third-party inspection before, during, and after the order, provide equipment running videos after completion, and offer factory training for buyers' engineers until they can operate and maintain independently. Overseas engineers are available for on-site installation and training. For specification assistance or certification confirmation, contact our technical team.
