# §98.30-7. Materials authorized for transfer to and from a portable tank.

- (a) The following hazardous materials may be transferred to and from a portable tank under this subpart:
  - (1) Any Grade D or Grade E combustible liquid listed in [§ 30.25-1](/cfr/46/30.25-1.md) of this chapter that does not meet the definition of any hazard class in [49 CFR part 173](/cfr/49/part173.md) other than that of “flammable liquid”, “combustible liquid”, “hazardous substance, or hazardous waste”;
  - (2) **Any corrosive liquid that—**
    - (i) Is compatible with the materials of the tank;
    - (ii) Meets the definition of no other hazard class in [49 CFR part 173](/cfr/49/part173.md); and
    - (iii) Is authorized for transport in an IM 101, IM 102, IMO Type 1, IMO Type 2, or UN portable tank under [subpart F](/cfr/46/subpartF.md) of [49 CFR part 173](/cfr/49/part173.md);
  - (3) Any hazardous material listed in Table 98.30-7(a)—Certain Hazardous Materials Authorized For Transfer To and From Portable Tanks;
  - (4) Any environmentally hazardous substance, liquid, N.O.S., Class 9, listed in table 1 of appendix A of [49 CFR 172.101](/cfr/49/172.101.md), and any aqueous solution of an environmentally hazardous substance, solid, N.O.S., Class 9, listed in that table, that meets the definition of “hazardous substance” in [49 CFR 171.8](/cfr/49/171.8.md); and
  - (5) Other cargoes subject to regulation under 49 CFR parts [171](/cfr/49/part171.md) through [176](/cfr/49/part176.md) when authorized in writing by the Commandant. Requests for such authorization must be submitted as prescribed in [§ 153.900(d)(1)](/cfr/46/153.900.md?p=d-1) of this chapter.
- (b) Grade D and Grade E combustible liquids with a flashpoint of 100 °F (38 °C) or higher by closed cup test that are not listed by name in the Hazardous Materials Table of [49 CFR 172.101](/cfr/49/172.101.md) may be transferred to and from an MPT, IM 101, IM 102, IMO Type 1, IMO Type 2, or UN portable tank conforming to the T Code “T1” specified in [49 CFR 172.102(c)(7)(i)](/cfr/49/172.102.md?p=c-7-i).

- (d) Sulfuric acid having a concentration of 65.25 percent or greater may be transferred to or from any portable tank; provided that the corrosion rate on steel, measured at 100 °F (38 °C), of sulfuric acid having a concentration of greater than 65.25 percent is not greater than the corrosion rate of such an acid having a concentration of 65.25 percent.
- (e) Environmentally hazardous substances (see [paragraph (a)(4)](#a-4) of this section) may be transferred only to and from an MPT, IM 101, IM 102, IMO Type 1, IMO Type 2, or UN portable tank.
