All packages containing dangerous goods must comply with the International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air, the International Air Transport Association (IATA) Dangerous Goods Regulations and, where applicable, Title 49 of the Code of Federal Regulations. Shippers of dangerous goods, whether prepared under ICAO/IATA or 49CFR, must comply with all FedEx Express variations listed in the current edition of the IATA tariff. The shipper is responsible for complying with all packing requirements and appropriate marking and labeling of the package, documentation, as well as compliance with applicable local, state, and federal laws, regulations, ordinances and rules. The shipper is also responsible for ensuring the recipient complies with all applicable local, state and federal laws, regulations, ordinances and rules for applicable hazard classes.
Shippers must comply with all applicable local, state and federal laws governing packing, marking and labeling of shipments of blood and blood products, regardless of whether they are infectious.
FedEx packaging may not be used to ship dangerous goods, with the following exceptions: IATA Section II lithium batteries, which may be shipped in FedEx boxes and tubes; and Biological Substance, Category B (UN 3373) shipments, which may be shipped in the FedEx UN 3373 Pak, the FedEx Medium Clinical Box or the FedEx Large Clinical Box. The shipper assumes sole responsibility for compliance with all applicable governmental regulations.
Shipments containing dangerous goods are not eligible for FedEx Express return options, except dry ice, which may be shipped using the FedEx Print Return Label and the FedEx Email Return Label. FedEx Express dangerous goods surcharges are not assessed on certain types of dangerous goods, and these may be shipped via FedEx Stamps. See the Dangerous Goods section at fedex.com for a list of dangerous goods that are not assessed a surcharge.
FedEx Express does not accept dangerous goods shipments prepared exclusively for ground shipment.
FedEx is not required to add dry ice to packages in its system, nor to provide re-icing services.
Common Fireworks (Division 1.4 explosives) will be accepted only with prior approval from FedEx.
Lithium batteries (UN 3090) that are Primary Non-Rechargeable require pre-approval to ship. This applies both to those that are fully regulated and those that meet the definition of IATA Section II lithium batteries. For details, go to fedex.com and enter keyword "lithium batteries."
If the recipient refuses a package containing dangerous goods, or the package leaks or is damaged, it will be returned to the shipper, if possible. If the shipper refuses to accept the returned shipment, or it cannot be returned because of leakage or damage due to faulty packaging, the shipper is responsible for and agrees to reimburse and otherwise indemnify FedEx for all costs, fees and expenses it incurs in connection with the cleanup and disposal of the package. The shipper agrees to indemnify FedEx for any and all costs, fees and expenses FedEx incurs as a result of the shipper's failure to comply with FedEx Dangerous Goods shipping requirements.
We have the right to refuse any package with an odor or any package that is wet or leaking. If a dangerous goods shipment damages or contaminates any property, the shipper is solely responsible for and will reimburse and indemnify FedEx for any and all costs, fees, and expenses it incurs in connection with the cleanup of such damage or contamination.
Not all FedEx locations accept dangerous goods, and we reserve the right to refuse dangerous goods at any location where they cannot be accepted in accordance with applicable law. Dangerous goods shipments, including dry ice, are not accepted at FedEx Express Drop Box locations, FedEx Office Print and Ship Center locations, FedEx Authorized ShipCenter locations, or FedEx ShipSite locations (such as OfficeMax), except as noted below. Biological Substance, Category B (UN 3373) shipments are not accepted at FedEx Office Print and Ship Center locations, FedEx Authorized ShipCenter locations, or FedEx ShipSite locations. Biological Substance, Category B (UN 3373) shipments may be placed in FedEx Express Drop Boxes, including drop boxes located at FedEx Office Print and Ship Center locations; they are not, however, accepted at drop boxes located at FedEx ShipSite locations. FedEx Express shipments containing IATA Section II lithium batteries are accepted at FedEx Office Print and Ship Center locations and may be placed in FedEx Express Drop Boxes.
The shipper must provide all required information and complete all boxes pertaining to dangerous goods on the FedEx airbill.
Note: We are required by law to report improperly declared or undeclared shipments of dangerous goods to the U.S. Department of Transportation (DOT). The shipper may be subject to fines and penalties under applicable law. The DOT/Federal Aviation Administration (FAA) requires every shipper to have job-specific dangerous goods training prior to tendering a dangerous goods shipment to FedEx or another air carrier. When individuals tender a shipment containing dangerous goods it must be properly classified, packaged, marked, labeled and identified as dangerous goods, and include the correct dangerous goods documentation.
Dangerous goods may not be rerouted to an address other than the original intended-recipient's address provided by the shipper. (Note: Shipments may be made available as hold for pickup or be returned to the sender.)
We are required to maintain proper segregation of incompatible dangerous goods on all vehicles and aircraft. This necessity may cause the shipment to move on the next available truck route or flight on which proper segregation can be maintained.
Accessible dangerous goods can be shipped via FedEx First Overnight Freight and FedEx 1Day Freight to and from primary service areas only. Inaccessible dangerous goods can be shipped via FedEx First Overnight Freight, FedEx 1Day Freight, FedEx 2Day Freight and FedEx 3Day Freight to and from primary and extended service areas.
