Power & Solar Energy Dangerous Goods, Cleared for YYZ.
Exporting solar energy storage systems, Battery Energy Storage Systems (BESS), industrial transformers, or renewable power equipment by air out of Toronto Pearson (YYZ)? AÉRO-DG prepares UN-certified packaging, 30% SoC battery compliance, and official IATA Shipper's Declarations.
Lithium Batteries and Transformers Don't Fly on Standard Paperwork.
BESS units, solar inverters with built-in batteries, and transformers filled with dielectric fluid are dangerous goods under IATA rules - shipping them by air without UN-certified packaging, verified State of Charge, and a correctly classed Shipper's Declaration means the airline turns them away at the counter. We handle the classification, packaging, and documentation so your equipment clears YYZ.
What AÉRO-DG Does for the Power & Solar Sector
Battery & Equipment Packaging
- → Battery Energy Storage Systems (BESS): high-capacity LiFePO4 & lithium-ion UN 3480 Class 9 packaging
- → Transformers & insulating liquids: Class 3 & Class 8 hazard compliance for dielectric fluids and power equipment
- → Solar inverters & controls: UN 3481 lithium battery contained in equipment compliance
- → 30% State of Charge (SoC) verification for lithium battery shipments
Cargo Aircraft Only (CAO) Compliance
- → Overpack labelling for CAO-restricted battery shipments
- → Red-hatched Shipper's Declarations prepared correctly the first time
- → YYZ freight tender coordination for CAO-only cargo
- → Documentation signed by IATA-certified DG specialist
UN-certified packaging and IATA documentation prepared for solar and power sector exporters shipping BESS units, transformers, and inverters through Toronto Pearson (YYZ).
How It Works
Tell us what's shipping
BESS units, transformers, solar inverters, or other power equipment - tell us the equipment type, battery chemistry, and destination so we can confirm the correct UN classification.
We package and verify compliance
UN-specification packaging matched to the hazard class, State of Charge verified against the 30% SoC rule for lithium batteries, and overpack labelling applied where CAO rules require it.
We prepare documents and tender at YYZ
Red-hatched Shipper's Declaration and supporting documentation completed, then tendered through the YYZ freight cargo process for your booked flight.
Built for the Power & Solar Energy Sector
From a single BESS export to recurring shipments of solar and grid equipment, we work the way clean tech and power sector companies actually ship - correctly classed, on time for YYZ cargo departures.
BESS & Battery Manufacturers
Exporting high-capacity LiFePO4 or lithium-ion Battery Energy Storage Systems? We handle UN 3480 Class 9 packaging and 30% SoC verification so your units clear the cargo counter.
Transformer & Power Equipment Suppliers
Shipping transformers or components with dielectric and insulating liquids? We manage Class 3 and Class 8 hazard compliance for the fluids involved.
Solar Inverter & Controls Exporters
Inverters and controls with a lithium battery contained in the equipment need UN 3481 compliance - we prepare the packaging and documentation for CAO tender.
Clean Tech Logistics & Procurement
Need a DG specialist to keep recurring power sector exports moving through YYZ? We work with logistics and procurement teams to keep documentation ready ahead of each shipment.
Power & Solar Exporters Ask Us
What UN number applies to solar battery storage systems?
High-capacity LiFePO4 and lithium-ion Battery Energy Storage Systems (BESS) ship under UN 3480 as Class 9 dangerous goods, which requires UN-specification packaging and an IATA Shipper's Declaration prepared to Class 9 requirements before the cargo can be accepted for an air shipment.
Do transformers need dangerous goods documentation for air freight?
Yes. Transformers and other power equipment containing dielectric or insulating liquids fall under Class 3 and Class 8 hazard rules depending on the fluid, so they need hazard-compliant packaging and documentation before they can be tendered for air cargo.
What is the 30% SoC rule for lithium batteries?
Lithium batteries shipped by air, including cells inside BESS units, generally need to be at 30% State of Charge (SoC) or below to meet air transport requirements. We verify SoC compliance as part of preparing the packaging and Shipper's Declaration for battery shipments.
Can solar inverters with built-in batteries fly as cargo?
Yes. Solar inverters and controls with a lithium battery contained in the equipment ship under UN 3481, and can move as Cargo Aircraft Only (CAO) freight once overpack labelling and a red-hatched Shipper's Declaration are prepared and tendered through YYZ.
