UN1760 corrosive liquid, n.o.s. table entry.

Where UN1760 sits in the table

UN1760 is a general entry for corrosive liquids not otherwise specified. The G in column 1 means one or more technical names of the hazardous material must be entered in parentheses in association with the basic description. 172.101(f) says that where more than one packing group is indicated, the packing group is determined using the criteria in subpart D of part 173. Class 8 is defined in 173.136(a) by irreversible damage to human skin at the site of contact within a specified period of time, or a severe corrosion rate on steel or aluminum.

The three rows show how steeply the air limits fall as the danger grade rises. For packing group I, column 9A is 0.5 L and column 9B is 2.5 L. For packing group II, 1 L and 30 L. For packing group III, 5 L and 60 L. Column 8A also differs: packing group I says None for the exceptions section while II and III say 154.

The table below sets the three rows side by side, copied from the eCFR text current through November 10, 2026 (read November 12, 2026). The last column says what each column of 172.101 means.

The 172.101 rows, column by column

How the regulation defines the hazard class

173.136(a) says, abridged: ""corrosive material" (Class 8) means a liquid or solid that causes irreversible damage to human skin at the site of contact within a specified period of time. A liquid, or a solid which may become liquid during transportation, that has a severe corrosion rate on steel or aluminum based on the criteria in 173.137(c)(2) is also a corrosive material."

Special provisions on this entry, in the rule's words

Column 7 does not explain itself; each code is defined in 172.102. These are the definitions as printed in the eCFR text for the codes listed on the rows. Where a provision ends with a list of conditions that this page does not reproduce, it says so.

• A7 (PG I): Steel packagings must be corrosion-resistant or have protection against corrosion.
• B10 (PG I): MC 300, MC 301, MC 302, MC 303, MC 305, and MC 306 and DOT 406 cargo tanks, and DOT 57 portable tanks are not authorized.
• B2 (PG II): MC 300, MC 301, MC 302, MC 303, MC 305, and MC 306 and DOT 406 cargo tanks are not authorized.
• IB2 (PG II): Authorized IBCs: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1).
• IB3 (PG III): Authorized IBCs: Metal (31A, 31B and 31N); Rigid plastics (31H1 and 31H2); Composite (31HZ1 and 31HA2, 31HB2, 31HN2, 31HD2 and 31HH2).

T14, TP2, TP27, T11, T7, TP1, TP28 are portable tank instructions or provisions, defined in 172.102(c)(7) and (c)(8). They are on the row but are not reproduced on this page.

What else to know about this entry

The packaging sections the row points to differ by packing group. Non-bulk packaging is 173.201, 173.202 and 173.203 for packing groups I, II and III, and bulk packaging is 173.243, 173.242 and 173.241 in the same order. The most dangerous grade, packing group I, is also the only one with the A7 corrosion-resistance rule and with B10, which bars several cargo tank types.

The ERG 2024 index lists five names under UN1760, all Guide 154: Chemical kit, Compounds cleaning liquid, Compounds tree or weed killing liquid (corrosive), Corrosive liquid n.o.s. and Ferrous chloride solution. That shows how broad the entry is. It also shows why the technical name matters: the n.o.s. name alone tells a responder little.

Column 10A is B for packing groups I and II and A for packing group III, and every row carries column 10B code 40, which 176.84 defines as stow clear of living quarters.

Air quantity limits and a worked example

Columns 9A and 9B give the largest net quantity allowed in one package: column 9A for passenger-carrying aircraft or passenger-carrying rail car, column 9B for cargo aircraft only. 172.101(j) says "Forbidden" means the material may not be offered for transportation or transported in the applicable mode, and that the limit is net unless stated otherwise. For UN1760 the PG I row shows 0.5 L in column 9A and 2.5 L in column 9B.

Worked example: a packing group I package holding 1 L net. Against column 9A (0.5 L), 1 L is over the limit, so it cannot go on a passenger aircraft or passenger-carrying rail car. Against column 9B (2.5 L), 1 L is within the limit, so the table allows it on a cargo aircraft only.

The same 1 L package would pass column 9A for packing group II (1 L) or III (5 L). The limit is per package, not per shipment, and the calculator above makes the same comparison for the quantity you type.

Choose the packing group row first, because the limits differ: PG I is 0.5 L and 2.5 L, PG II is 1 L and 30 L, PG III is 5 L and 60 L (columns 9A and 9B).

Highway placard check

Class 8 is on Table 2 of 172.504(e) as CORROSIVE.

By highway or rail, 172.504(c) says placards are not required on a vehicle or freight container carrying less than 454 kg (1,001 pounds) aggregate gross weight of Table 2 materials. Bulk packagings and materials subject to 172.505 are excepted from that relief.

The weight counts every Table 2 material on the vehicle, not only this UN number. In the calculator, 1,000 pounds of non-bulk Table 2 material returns "not required", 1,001 pounds returns "required", and any bulk packaging returns "required".

Vessel stowage and the ERG guide

Column 10A gives category B (the material may be stowed "on deck" or "under deck" on a cargo vessel and on a passenger vessel carrying a limited number of passengers, and "on deck only" on passenger vessels above that number); category A (the material may be stowed "on deck" or "under deck" on a cargo vessel or on a passenger vessel). Column 10B lists 40. Code 40 in 176.84: Stow "clear of living quarters". These apply to shipments by vessel and have no effect on a truck-only move.

The Emergency Response Guidebook 2024 numerical index lists UN1760 under Guide 154, titled "Substances - Toxic and/or Corrosive (Non-Combustible)". 172.101 itself does not list ERG guide numbers; the guide number comes from the PHMSA guidebook. The guide is for first responders during the initial phase of an incident and is not a shipping-paper or compliance document.

What this page does not do

This page reproduces the table rows and the regulation text they point to, and applies the air-limit and 1,001 pound placard comparisons to numbers you enter.

It does not classify a product, pick a packing group or decide which row applies to your shipment. It does not replace the packaging sections in columns 8A to 8C, the marking, labelling and shipping paper rules in part 172, or hazmat training. Hazardous materials employees must be trained, and the shipping description belongs to a trained person.

The eCFR header for 172.101 links an amendment published at 91 FR 49310 (August 4, 2026); confirm that the version you rely on includes the latest changes. In an emergency call 911 and the emergency response telephone number on the shipping paper.
