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. 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. When new chemicals or product mixtures are proposed for mass sand, they are usually subject to a so-called tripartite agreement. The objective of a tripartite agreement is to allow the relatively rapid shipment of a new product for a transitional period before the IMO conducts the final assessment. 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.
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. 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. In particular, for ships that often request tripartenary addendums, usually package chemical tankers, the new product list is a better alternative than asking for an endorsement each time a tripartie product is destined to be transported. 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, as many requests have recently been made by shipowners.
