Flexitank Quality List – FQL

The Flexitank Quality List provides information to COA Carriers (Shipping Lines) for use as may be required during their risk assessment process.

Flexitank members that demonstrate conformance with the COA Code of Practice are awarded the COA Quality Conformance (see Table 1).

The COA Flexitank Code of Practice details requirements of flexitank manufacture, operation and the requirements of the quality conformance scheme.

Conformance with the quality scheme is demonstrated by the flexitank company undergoing independent audits and tests.

The CQC is required for each Manufacturer and each Operator.

The CQC is required for each flexitank design and type and each manufacturing site. Some companies supply more than one type and design of flexitanks and manufacture at more than one factory site.

Flexitanks should display a unique design reference being the design tested and displayed on the FQL. Each flexitank design requires a CQC audit.

The dates recorded on the FQL refer to the expiry date of the audit

The CQC is not issued in document form. Companies requiring a document should download the FQL.

An Original Equipment Manufacturer (OEM) is the company that manufacturers the flexitank, constructing the flexitank from materials purchased from suppliers. The OEM designs, develops and undertakes quality assurance but the OEM might additionally manufacturer flexitanks designed or modified by a flexitank operator or another company The OEM provides its manufactured flexitank to Operators and other industrial users. Some manufacturers might also provide operator services.

An Operator procures and manages the use of the flexitank including providing services to shippers (cargo producers) such as supply, cargo risk assessment, transport logistics, arranging installation into the container and removal of the used flexitank and recycling. Some operators might design flexitanks (OD) to meet their own requirements and arrange manufacturer of their design by an OEM.
