Section 2 Assessed substances
2.1 If the liquid is to be shipped as a chemical, the shipper should first check whether it is listed in chapter 17 or 18 of the IBC Code, excluding "Noxious (or non-noxious) liquid, n.o.s." generic entries.
2.2 The liquids listed in the IBC Code are mainly pure or technically pure chemicals, including their aqueous solutions.
2.4 The Index of Dangerous Chemicals Carried in Bulk, issued by IMO, gives most of the commonly used synonyms of the chemicals listed in the IBC Code. The index is also expected to be expanded every two years in line with the IBC Code.
2.5 It is important that a chemical listed in the IBC Code is shipped under the name listed in the Code, instead of under a synonym, for ease of identification by all those involved in its transport.
2.6 If the chemical is not listed in the IBC Code, the next step is to check the agreed and proposed amendments to chapter 17 or 18 of the IBC Code and the list of chemicals provisionally assessed by IMO. Such a list is issued periodically under the cover of an MEPC circular.
2.7 If the chemical is neither listed in the IBC Code, nor provisionally assessed by IMO, it is necessary to check whether it has already been provisionally assessed by tripartite agreement by the shipping or producing country, flag States and receiving countries for the intended shipment.
2.8 A list of chemicals provisionally assessed by tripartite agreement is issued periodically under cover of an MEPC circular different from that mentioned in 2.6. The same circular also includes a separate list of pollutant-only mixtures of assessed substances, covered later in section 5.
2.9 If the shipping or producing country is already a Party to a provisional assessment of the chemical in question, of which one or more of the flag States and/or receiving countries are not Parties, the shipping or producing country will ask them to join in the existing agreement.
2.10 If the chemical has already been assessed by tripartite agreement by other Parties, the shipping or producing country should review the basis of the precedent assessment, with a view to concurring with it, unless new data are available or a more accurate assimilation is proposed. In this case, the chemical should be reassessed (see 4.5 to 4.7).
2.11 If the chemical proposed for shipment is found in the list referred to in 2.8, the shipping or producing country should inform those among the flag States and the receiving countries which have not yet been informed that the chemical has already been assigned to a generic entry in the IBC Code.
