IMO will conduct a definitive assessment of the products on the basis of their physical and toxicological properties, as presented by the producing country. The product is then valid for all countries without an expiration date and is included in the standard certificate-fitness list (CoF). The conditions of transport can be changed by the tripartite agreement. DNV GL now offers a list of certificate-for-fitness products that contain all products that have not yet been officially evaluated by IMO, but which are still subject to what is called a tripartite agreement. This facilitates the certification process by listing all tricolor products on a single list, as opposed to a single product supplement. While the finalized evaluated products for which a ship is certified are included in the standard CoF product lists, only one product supplement is added to the CoF, which covers only this specific tripartenary product. The new tripartite list will contain all current trilateral products at the time of the exhibition, for which the vessel can be certified and the ship`s flag is a signatory state. At the next opportunity, the operator should consider urgently requesting a tripartite list instead of an endorsement to certify the vessel for all products currently available. This information is ready to provide chemical tanker owners and stakeholders with detailed explanations of tripartite agreements for each list in the circular, given that there have been numerous recent requests from shipowners. On the new list, the signatory states and tripartite expiration dates for each product are listed in addition to standard mentions such as the tanks in which the product can be transported, the footnotes and the MARPOL pollution category.

Korean Registry has issued a technical circular on tripartite agreements for the provisional categorization of liquid materials in the code IBC ref to MEPC.2/Circ.18 wrt. 2.1 Because chemical manufacturers are constantly manufacturing new products that are not yet included in the IBC code, products are evaluated and classified by the country`s government for production, import or shipment for transport on board chemical tankers. When it is proposed to carry a bulk liquid substance that has not been included in the code, the governments of the parties to the proposed transaction will conduct a preliminary assessment of the proposed transaction on the basis of the Schedule II/Reg project. 6.2 IMO sets and will agree on these guidelines. Once tripartite agreements have been notified to IMO, product evaluation agreements (or trade names) are issued in the form of MEPC.2/Circular. The agreement applies only to signatory states and does not exceed three years. This means that cargo can only be shipped on ships flying the flag of a signatory country and between the ports of the countries that are part of the agreement. The new lists of three as existing addendums will only be issued on request. The tax for the tripartite list will not exceed the price of two or more addendums.

The benefit will be a greater likelihood that the next tripartite product to be shipped will already be covered by the CoF, thereby reducing administrative and certification costs.
