The U.S. Federal Aviation Administration has proposed fining Amazon $130,000 over two incidents in 2014 when it shipped or attempted to ship hazardous goods by air.
The flight safety regulator says Amazon shipped the packages without warning labels, paperwork that specified the chemicals inside, or emergency response information.
The proposed penalty comes two weeks after the FAA fined Amazon $350,000 over a similar incident that caused injuries to several UPS workers.
The first of the two latest fines relates to a shipment made in May 2014, when Amazon sent two packages containing a rust-stain removing product from Illinois to Florida.
The shipments were discovered by FedEx workers when they began to leak.
Amazon has 30 days to respond to the allegations.
