> Largest export: Aircraft and parts
> 2019 Aircraft and parts export value: $14.6 billion
> Aircraft and parts as share of total state 2019 exports: 44.1%
Like a number of U.S. states, airplanes and airplane parts is Kentucky’s largest export, accounting for more than 44% of the state’s $11.7 billion in total exports. The state is home to a reported 79 aerospace facilities — including some run by General Electric, Lockheed Martin, and Raytheon — which employ more than 19,000 people. Mexico, Canada, and Japan are the top three export destinations for products from Kentucky.
> Largest export: Liquid petroleum
> 2019 Liquid petroleum export value: $20.6 billion
> Liquid petroleum as share of total state 2019 exports: 32.3%
Petroleum is Louisiana’s most valuable export by a wide margin. The Bayou State exported more than $20 billion worth of petroleum in 2019, equal to more than 32% of the total value of the state’s exports that year.
While petroleum drilling has been an integral part of the state’s economy for decades, the industry has suffered some major setbacks in recent years. Hurricane Katrina damaged offshore rigs in 2005, curbing extraction for months. In 2010, the Deepwater Horizon oil platform exploded, killing 11 workers and spilling millions of barrels of oil into the Gulf. Due to reduced oil prices and climbing production costs, Louisiana’s total crude oil output hit a six-decade low in 2019.
> Largest export: Crustaceans
> 2019 Crustaceans export value: $368.4 million
> Crustaceans as share of total state 2019 exports: 13.5%
Crustaceans, such as lobster, account for more than 13% of the $2.7 billion value of goods exported from Maine in 2019. While just over half of Maine’s total exports, including lobster, end up in Canada, Maine would likely export even more of its top product if not for the U.S. trade war with China. In the first half of 2018, Maine exported $87 million worth of lobster to China. However, following tariffs imposed in July 2018, demand for Maine lobster in China dropped a staggering 84%.
> Largest export: Aircraft and parts
> 2019 Aircraft and parts export value: $1.6 billion
> Aircraft and parts as share of total state 2019 exports: 11.9%
In 2019, Maryland exported $1.6 billion worth of aircraft and parts, a 110% increase from the year prior. The state is home to facilities of some of the nation’s top aerospace and defense companies, including BAE Systems, Lockheed Martin, and Northrop Grumman
In recent years, Maryland has also cultivated a new export market — petroleum gas. While the state has very few natural gas resources and in 2017 became the third U.S. state to ban fracking, in early 2018, the state opened a terminal for the export of natural gas in Chesapeake Bay. The terminal — which employs 4,500 workers and was the most expensive private sector project in Maryland history, according to some officials — mostly ships natural gas from Pennsylvania and other surrounding states. In 2019, Maryland exported $1.5 billion of petroleum gas, the second most of any product category in the state.
> Largest export: Medical Instruments
> 2019 Medical Instruments export value: $2.7 billion
> Medical Instruments as share of total state 2019 exports: 10.3%
Massachusetts exported $2.7 billion worth of medical instruments in 2019, more than any other product category. Medical instruments accounted for 10.3% of the state’s total exports, followed by gold and semiconductor manufacturing machines, which accounted for 8.1% and 4.4% of exports, respectively. Medical device makers in the state include Abiomed, Boston Scientific, and Philips Healthcare. The top three foreign markets for exports from Massachusetts are Canada, China, and Mexico.
