Section 178.705 prescribes standards for metal IBCs. Paragraph (a)(3) indicates
that IBC specifications 31A, 31B, and 31N are authorized for both liquids and solids.
PHMSA is revising this sentence editorially by removing the authorization to package

This editorial change is consistent with the § 172.102 IBC Code Table revisions in
paragraph (c)(4) and other IBC standards (e.g., § 178.707(a)(5)) prescribed in subpart N of

Section 178.910

minimum marking size must be 12 mm in height.
Furthermore, paragraph (b) of this section is now reserved. However, we are
