Key takeaways
UN1760 identifies Corrosive liquid, n.o.s., not every corrosive chemical or corrosive solid.
Use a more specific shipping entry when the applicable classification rules require it.
Packing group and transport mode determine the permitted package and quantity conditions.
Package labels and vehicle placards are different hazard-communication tools.
UN1760 identifies “Corrosive liquid, n.o.s.” in dangerous goods transport. The abbreviation means not otherwise specified. It is a generic shipping entry for a corrosive liquid when that entry is appropriate under the applicable classification rules.
UN 1760 does not identify one chemical formulation, and it does not cover all corrosive materials. A corrosive solid needs a different entry. Many named acids, bases and mixtures also have more specific shipping descriptions.
What is UN1760 used for?
The UN1760 corrosive liquid entry can apply to qualifying liquids or mixtures when the transport classification supports that generic description. The shipper must first establish the material's hazards and select the proper shipping name, including any more specific applicable entry.
Do not use the 1760 chemical code as a substitute for the actual identity of the contents. The same UN number can cover different formulations. Hazard class, subsidiary risks, packing group, technical-name requirements and transport restrictions must be assessed for the specific material.
Mercury's UN1760 glossary entry provides a shorter reference. This guide focuses on the preparation decisions after the material has been assessed.
Check the jurisdiction before reusing a classification
US Class 8 definitions and packing-group criteria appear in 49 CFR 173.136 and 173.137. Air and maritime movements bring their applicable modal provisions as well.
Canada illustrates why jurisdiction matters: Transport Canada warns against using UN1759 and UN1760 where more precise corrosive shipping names are available. Do not turn that Canadian guidance into a claim that the UN1760 entry is invalid everywhere. Confirm the classification rules for the actual movement.
UN1760 packing group and packaging selection
A UN1760 packing group cannot be inferred from the number alone. Packing groups express the degree of danger under the relevant criteria. Review the classification evidence and the exact entry before choosing a package.
Packing group | Relative degree of danger | Packaging implication |
|---|---|---|
I | High | Use packaging permitted for the exact entry and high-danger conditions |
II | Medium | Confirm the permitted package type, performance level and quantity |
III | Lower | Apply the relevant package and exception conditions without assuming no regulation |
The selected container must be chemically compatible with the liquid and authorized for its packing group and transport mode. A UN specification mark alone does not establish compatibility, correct closure or permission to carry any quantity.
Use the manufacturer's assembly and closure instructions. Check seals, torque where specified, inner receptacles, cushioning or absorbent material where required, and any orientation restrictions. Package performance must remain suitable through expected temperature and pressure changes.
Class 8 labels and the 1760 placard meaning
A Class 8 package label communicates the corrosive hazard. Required package markings identify the shipping entry and other information. A vehicle or bulk-container placard serves a different role and is subject to separate placarding rules.
The 1760 placard meaning is the identification of the associated corrosive-liquid shipping entry on the transport unit when displayed under the relevant rules. The number is not a concentration, severity score or unique chemical name. A package label should not be substituted for a placard, or a placard treated as the complete package marking.
For hazmat 1760 consignments, confirm whether the movement requires placards and identification numbers based on the quantity, packaging and transport arrangement. Domestic exceptions and international requirements can differ.
Documents and carrier acceptance
Class 8 corrosive shipping requirements can include a proper shipping description, technical name where required, quantity, packaging details, emergency-response information and modal documentation. A safety data sheet supports the assessment, but its transport section should be checked against the current shipment and regulations.
The 1760 hazmat code does not itself establish airline or parcel-carrier acceptance. Confirm service availability, account authorization, aircraft limitations where applicable and the carrier's specific conditions before pickup. Trained personnel should prepare and review regulated shipping documents.
For cross-border shipments, Mercury's commercial invoice guide addresses the separate customs document. US chemical imports may also need the assessment described in the TSCA certification guide.
Release checks for the completed package
Before tender, verify the complete shipment rather than only the outer label:
Confirm the exact material, hazard assessment, proper shipping entry and packing group.
Check authorized packaging, chemical compatibility, quantity and closure instructions.
Inspect required marks, labels, overpack information and any placarding arrangements.
Reconcile transport documents, emergency information and customs records.
Confirm trained handling, carrier acceptance and receiving capability.
Keep emergency actions within the site's trained response procedures. A leaking package or exposure requires isolation and escalation to appropriate responders, rather than an improvised neutralization attempt. A supported classification and a correctly assembled, accepted package are the foundation of the shipment plan.
