本条款规定，曾装载7类（放射性）材料且已尽可能排空内容的包装容器，在满足特定条件时可豁免运输单据及标记要求（UN编号标记除外）。关键条件包括：符合§173.421部分要求、包装完好无泄漏、铀/钍外层有惰性护套、内部污染不超过限值100倍、移除原标签并粘贴“Empty”标签、以及按§173.422准备发运。该规则旨在简化合规的空放射性包装回收或转运流程，但需严格核查物理状态与污染水平。
A packaging which previously contained Class 7 (radioactive) materials and has been emptied of contents as far as practical, is excepted from the shipping paper and marking (except for the UN identification number marking requirement described in § 173.422(a)) requirements of this subchapter, provided that—
- (a) The packaging meets the requirements of § 173.421 (b), (c), and (e) of this subpart;
- (b) The packaging is in unimpaired condition and is securely closed so that there will be no leakage of Class 7 (radioactive) material under conditions normally incident to transportation;
- (c) The outer surface of any uranium or thorium in its structure is covered with an inactive sheath made of metal or some other substantial material;
- (d) Internal contamination does not exceed 100 times the limits in § 173.443(a);
- (e) Any labels previously applied in conformance with subpart E of part 172 of this subchapter are removed, obliterated, or covered and the “Empty” label prescribed in § 172.450 of this subchapter is affixed to the packaging; and
- (f) The packaging is prepared for shipment as specified in § 173.422.
