Can I ship an UN3481 UPS?
Yes, UN3481-labeled UPS devices can be shipped, but they require strict compliance with Class 9 dangerous goods regulations. UN3481 applies to lithium-ion batteries contained in equipment (like UPS units), mandating certified packaging, hazard labels, and documentation including MSDS, UN38.3 test reports, and shipping declarations. Non-compliance risks penalties or cargo confiscation.

What defines UN3481 classification for UPS systems?
UN3481 covers lithium-ion batteries permanently installed in equipment, distinguishing them from standalone batteries (UN3480). UPS units qualify if batteries are integrated and non-removable. Pro Tip: Always verify battery installation method—removable power packs may require separate UN3480 compliance.
Technical specifications include watt-hour limits (≤100 Wh per battery) and prohibition of damaged cells. For example, a 500VA UPS with a built-in 48V Li-ion battery pack typically falls under UN3481. Transitionally, while UN3481 simplifies documentation compared to standalone batteries, it still requires Class 9 hazard labels. But what if the UPS contains lead-acid batteries? Those fall under UN2794 instead, highlighting the need for precise chemistry identification. Pro Tip: Use UN-certified packaging with inner leak-proof liners—corrugated cardboard alone violates IATA/IMDG rules.
What documentation is mandatory for shipping UN3481 UPS?
Three critical documents: Safety Data Sheets (SDS), UN38.3 test summaries, and a Shipper’s Declaration for Dangerous Goods. Airlines and freight forwarders routinely reject shipments missing any of these. Practically speaking, the UN38.3 report must cover altitude simulation, thermal shock, and short-circuit tests performed within the last 12 months.
| Requirement | UN3480 | UN3481 |
|---|---|---|
| Packaging | UN-certified outer box | Equipment-protected casing |
| Label | Lithium battery Class 9 | Lithium battery in equipment Class 9 |
| Documentation | Full DG declaration | Simplified declaration (if ≤4 batteries) |
For example, a UPS containing two 72Wh lithium batteries shipped via air requires a “Lithium Battery in Equipment” mark instead of full hazard labels if packed according to PI 967 Section II. However, what happens when shipping 10 units? You’ll trigger full dangerous goods paperwork regardless of battery count. Pro Tip: Pre-notify carriers 72 hours before dispatch—airlines often limit lithium battery shipments per aircraft.

FAQs
No, all modes require DG documentation. Ground transport (USDOT) still needs shipping papers with emergency contact info and proper placards.
Are used/refurbished UPS units under UN3481 subject to different rules?
Yes, used equipment requires additional testing—manufacturers must prove batteries pass new UN38.3 criteria after refurbishment. Damaged units are banned from air transport.
