UN FIBC Codes Explained
UN FIBC codes refer to the markings on Flexible Intermediate Bulk Containers (FIBCs), which are large industrial containers made of flexible fabric designed for storing and transporting dry, flowable products. These codes indicate the type and performance of the FIBC, ensuring it meets specific regulatory standards for transporting hazardous materials. Here is an explanation of the components of a UN FIBC code:
UN Symbol
The "UN" in a circle indicates that the container meets United Nations requirements for transporting hazardous materials.
Type of FIBC:
- 13H1: Woven plastic fabric, without coating and without liner.
- 13H2: Woven plastic fabric, coated and without liner.
- 13H3: Woven plastic fabric, uncoated and with liner.
- 13H4: Woven plastic fabric, coated and with liner.
Packaging Group Performance Standard
- X: For Packing Group I (high danger).
- Y: For Packing Group II (medium danger).
- Z: For Packing Group III (low danger).
Maximum Gross Mass
The maximum weight the FIBC can safely carry.
Year of Manufacture
The year the FIBC was produced.
Country Authorizing the Mark
The country code of the country that authorized the UN marking.
Manufacturer's Code
A code identifying the manufacturer of the FIBC.
Additional Information
Sometimes additional information is included, such as the type of liner used, specific gravity for liquids, or other performance criteria.
For example, a UN FIBC code might look like this: UN 13H4/Y/2500/22/USA/MFG1234
Breaking it down
- UN: United Nations symbol.
- 13H4: Woven plastic fabric, coated and with liner.
- Y: Suitable for Packing Group II (medium danger).
- 2500: Maximum gross mass in kilograms.
- 22: Year of manufacture (2022).
- USA: Country authorizing the mark.
- MFG1234: Manufacturer's code.
These codes ensure that FIBCs used for hazardous materials comply with international regulations and are safe for transport and handling.
