A. Yes. Section 172.504(c) provides an exception from the placarding requirements for hazardous materials listed in Table 2 of § 172.504(e), provided the hazardous materials are contained in non-bulk packages and the aggregate gross weight of Table 2 materials contained in a single transport vehicle or freight container does not exceed 454 kg (1,001 pounds).

A. International placards are permitted domestically if the shipments are prepared in accordance with recognized international standards (i.e., International Civil Aviation Organization's Technical Instructions, IMDG Code, or Canadian Transport of Dangerous Goods Regulations). See § 171.22.

A. A freight container, unit load device, transport vehicle, or rail car containing non-bulk packages with two or more categories of hazardous materials that require different placards specified in Table 2 of § 172.504(e) may be placarded with a DANGEROUS placard instead of the separate placarding specified for each of the materials in Table 2. However, when 1,000 kg (2,205 pounds) aggregate gross weight or more of one category of material is loaded at one loading facility on a freight container, unit load device, transport vehicle, or rail car, the placard specified in Table 2 of paragraph (e) of this section for that category must be applied.

A. Class 9 (Miscellaneous) materials, although listed in Table 2, are not required to be placarded for domestic transportation (see §172.504(f)(9)). However, a bulk packaging containing a Class 9 (Miscellaneous) material must be marked with the appropriate ID number, which can be displayed on a Class 9 placard, an orange panel, or a white square-on-point display.

A. The new Organic Peroxide label and placard designs feature a red background in the top half and a yellow background in the lower half. In addition, the text, division number, and inner border of the placard must be black; however, the symbol may be either black or white. The new label and placard design may be used now. You may continue to use the old style label design until January 1, 2011. You may continue to use the old style placard until January 1, 2014, by highway, and until January 1, 2011, by rail, vessel, or aircraft.
