本条款规定了危险品在货运集装箱（Freight Container）和航空集装器（ULD）中的标识要求。核心依据是容积阈值：容量≥640立方英尺的容器必须按§172.504张贴标牌（Placards），但存在特定豁免情形；容量<640立方英尺的容器若通过空运，通常需张贴一个标牌或符合标签/ICAO识别标准，非空运则可用标签替代标牌。此外，所有空运危险品包装仍需接受§175.30的检查。建议相关方核实具体运输方式与容器规格以确定合规标识方案。

(a) Capacity of 640 cubic feet or more. Each person who offers for transportation, and each person who loads and transports, a hazardous material in a freight container or aircraft unit load device having a capacity of 640 cubic feet or more shall affix to the freight container or aircraft unit load device the placards specified for the material in accordance with § 172.504. However:

- (1) The placarding exception provided in § 172.504(c) applies to motor vehicles transporting freight containers and aircraft unit load devices,

- (2) The placarding exception provided in § 172.504(c) applies to each freight container and aircraft unit load device being transported for delivery to a consignee immediately following an air or water shipment, and,

- (3) Placarding is not required on a freight container or aircraft unit load device if it is only transported by air and is identified as containing a hazardous material in the manner provided in part 7, chapter 2, section 2.8, of the ICAO Technical Instructions (IBR, see § 171.7 of this subchapter).

(b) Capacity less than 18 m 3 (640 cubic feet). (1) Each person who offers for transportation by air, and each person who loads and transports by air, a hazardous material in a freight container or aircraft unit load device having a capacity of less than 18 m 3 (640 cubic feet) shall affix one placard of the type specified by paragraph (a) of this section unless the freight container or aircraft unit load device:
(i) Is labeled in accordance with subpart E of this part, including § 172.406(e);

- (ii) Contains radioactive materials requiring the Radioactive Yellow III label and is placarded with one Radioactive placard and is labeled in accordance with subpart E of this part, including § 172.406(e); or,

- (iii) Is identified as containing a hazardous material in the manner provided in part 7; chapter 2, section 2.8, of the ICAO Technical Instructions (IBR, see § 171.7 of this subchapter).

- (2) When hazardous materials are offered for transportation, not involving air transportation, in a freight container having a capacity of less than 640 cubic feet the freight container need not be placarded. However, if not placarded, it must be labeled in accordance with subpart E of this part.

(c) Notwithstanding paragraphs (a) and (b) of this section, packages containing hazardous materials offered for transportation by air in freight containers are subject to the inspection requirements of § 175.30 of this chapter.
