For each listed material, the Table identifies the hazard class or specifies that the material is forbidden in transportation, and gives the proper shipping name or directs the user to the preferred proper shipping name. In addition, the Table specifies or references requirements in this subchapter pertaining to labeling, packagingquantity limits aboard aircraft and stowage of hazardous materials aboard vessels.
When a plus sign is assigned to mixtures or solutions containing a material where the hazard to humans is significantly different from that of the pure material or where no hazard to humans is posed, the material may be described using an alternative shipping name that represents the hazards posed by the material. An appropriate alternate proper shipping name and hazard class may be authorized by the Associate Administrator. An alternate proper shipping name may be selected when either domestic or international transportation is involved.
An alternate proper shipping name may be selected when only domestic transportation is involved. Hazardous materials descriptions and proper shipping names.
Column 2 lists the hazardous materials descriptions and proper shipping names of materials designated as hazardous materials. Modification of a proper shipping name may otherwise be required or authorized by this section. Proper shipping names are limited to those shown in Roman type not italics. However, the entry in the Table reflects the preferred sequence.
Thus, Iodine monochloride may be used interchangeably with Iodine chloride. When the packaging specified in Column 8 is inappropriate for the physical state of the material, the table provided in paragraph i 4 of this section should be used to determine the appropriate packaging section.
B The shipping description indicates that the proper shipping name applies only to the pure or technically pure hazardous material. C The hazard classpacking groupor subsidiary hazard of the mixture or solution is different from that specified for the entry.

D There is a significant change in the measures to be taken in emergencies. The name that most appropriately describes the material shall be used; e.
Under the provisions of subparts C and D of this part, the technical names of at least two components most predominately contributing to the hazards of the mixture or solution may be required in association with the proper shipping name. C A sample must be transported in a combination packaging tahle conforms to the requirements of this subchapter that are applicable to the tentative 172.01 group assigned, and may not exceed a net mass of 2.
If an appropriate technical name is not shown in the Table, selection of a proper shipping name shall be made from the generic or n. Under the provisions of subparts C and D of this part, the technical name of one or more constituents which makes the product a hazardous material may be required in association with the proper shipping name.

This prohibition does not apply if the material is diluted, stabilized or incorporated in a device and it is classed in accordance with the definitions of hazardous materials contained in part of this subchapter. Column 4 lists the identification number assigned to each proper shipping name. Column 5 specifies one or more packing groups assigned to a material corresponding to the proper shipping name and hazard class for that material.
Class 2, Class 7, Division 6. Articles in other than Class 1 are not assigned to packing groups. For packing purposes, any requirement for a specific packaging performance level is set out in the applicable 12.101 authorizations of part If more than one packing group is indicated for an entry, the packing group for the hazardous material is determined using the criteria for assignment of packing groups specified in subpart D of part When a reevaluation of test data or new data indicates a need to modify the specified packing group sthe data should be submitted to the Associate Administrator.
Column 6 specifies codes which represent the hazard warning labels required for a package filled with a material tablr to the associated hazard class and proper shipping nameunless the package is otherwise excepted from labeling by a provision in subpart E of this part, or part of this subchapter. The first code is indicative of the primary hazard of the material. Additional label codes are indicative of subsidiary hazards.
No label is required for a material classed as a combustible liquid or for a Class 3 material that is reclassed tabke a combustible liquid. The codes contained in Column 6 are defined according to the following table:.
Column 7 specifies codes for special provisions applicable to hazardous materials. Columns 8A, 8B and 8C specify the applicable sections for exceptions, non-bulk packaging requirements and bulk packaging requirements, respectively, in part of this subchapter.
Column 8A contains exceptions from some of the requirements of this subchapter. The referenced exceptions are in addition to those specified in subpart A of part and elsewhere in this subchapter. Column 8B references the section in part of this subchapter which prescribes packaging requirements for non-bulk packagings. Column 8C specifies the section in part of this subchapter that prescribes packaging requirements for bulk tabpesubject to the limitations, requirements, and additional authorizations of Columns 7 and 8B.
Additional authorizations and limitations for use of UN portable tanks are set forth in Column 7. For cylinders, both non-bulk and bulk packaging authorizations are set forth in Column 8B. 172.1001
Columns 9A and 9B specify the maximum quantities that may be offered for transportation in one package by passenger-carrying aircraft or passenger -carrying rail car Column 9A or by cargo aircraft only Column 9Bsubject to the following:. If one material is a liquid and one is a solidthe maximum net quantity must be calculated in kilograms.
Column 10A [Vessel stowage] specifies the authorized stowage locations on board cargo and passenger vessels. Column 10B [Other provisions] specifies codes for stowage and handling requirements for specific hazardous materials.
Hazardous materials offered for transportation as limited quantities are allocated stowage category A and are not subject to the stowage codes assigned by column 10B. For bulk transportation by vesselsee 46 CFR parts 30 to 407098,and The authorized stowage locations specified in Column 10A are defined as follows:. Cornell Law School Search Cornell.
