本条款规定美国运输部（DOT）对第1类爆炸品包装标记的强制性要求。核心义务是：除非符合特定豁免，每个装有第1类材料的包装必须标注对应的EX编号。允许使用国防部库存号、商业产品代码或烟花认证机构（FCA）分配的FC编号作为替代，但需确保可追溯至具体EX/FC编号。若同一包装内超过5种不同第1类材料，仅需标注其中5个编号。该规定直接影响危险品出口美国的合规申报与包装操作，建议相关方核实现有标签是否符合最新追溯性要求。

(a) Except as otherwise provided in paragraphs (b), (c), (d) and (e) of this section, each package containing a Class 1 material must be marked with the EX-number for each substance, article or device contained therein.
(b) Except for fireworks approved in accordance with § 173.64 of this subchapter, a package of Class 1 materials may be marked as follows, in lieu of the EX number required by paragraph (a) of this section:

- (1) With a national stock number issued by the Department of Defense or identifying information, such as a product code required by regulations for commercial explosives specified in 27 CFR part 555, if the national stock number or identifying information can be specifically associated with the EX number assigned; or

- (2) For Division 1.4G consumer fireworks reviewed by a Fireworks Certification Agency approved in accordance with 49 CFR part 107 subpart E and certified in accordance with § 173.65, with the FC number assigned by a DOT-approved Fireworks Certification Agency.

(c) When more than five different Class 1 materials are packed in the same package, the package may be marked with only five of the EX-numbers, national stock numbers, product codes, or combination thereof.
(d) The requirements of this section do not apply if the EX number, FC number, product code or national stock number of each explosive item described under a proper shipping description is shown in association with the shipping description required by § 172.202(a). Product codes and national stock numbers must be traceable to the specific EX number assigned by the Associate Administrator or FC number assigned by a DOT-approved Fireworks Certification Agency.
(e) The requirements of this section do not apply to the following Class 1 materials:

- (1) Those being shipped to a testing agency in accordance with § 173.56(d) of this subchapter;

- (2) Those being shipped in accordance with § 173.56(e) of this subchapter, for the purposes of developmental testing;

- (3) Those which meet the requirements of § 173.56(h) of this subchapter and therefore are not subject to the approval process of § 173.56 of this subchapter;

- (4) [Reserved];

- (5) Those that are transported in accordance with § 173.56(c)(2) of this subchapter and, therefore, are covered by a national security classification currently in effect.
