摘要总结AI 辅助解读

该条款规定了白磷或黄磷在美国境内通过铁路、公路或水路运输时的包装要求。核心原则是必须采用一级包装组（PG I）性能标准的容器，且需浸没在水中或干燥固态封装。若用水封，须使用特定规格的金属/木箱或钢桶，并满足24小时静置观察、一次性使用及仅限私人/合同承运人等严格条件；若干运，须铸成固体装入不超过115升的金属桶中。违反包装规范将导致严重的合规风险与拒运后果。

Phosphorus, white or yellow, when offered for transportation or transported by rail, highway, or water, must be packaged in water or dry in packagings conforming to the requirements of part 178 of this subchapter at the Packing Group I performance level, as follows:

(a) When placed in water, it must be packaged in specification packagings as follows:

- (vi) Transportation is by private or contract motor carrier only; and

- (vii) Transportation is authorized from the offeror's location to a facility where it must be unloaded by the consignee.

(b) When dry, it must be cast solid and shipped in packagings as follows:
