Saudi Arabia has been an enticing trade partner with the United States from the early 20th century. The biggest commodity traded between the two nations is oil. The strength of the relationship is notoriously attributed to the United States' demand on oil throughout the post modern era, approximately 10,000 barrels of petroleum are imported daily to United States since 2012 (U.S. Total Crude Oil and Products Imports). Saudi Arabia has consistently been in need of weapons, reinforcement, and arms due to the consistent rising tensions throughout the Middle East during the late 20th century and early 21st century. Post 2016, the United States of America has continued to trade with Saudi Arabia mainly for their oil related goods. The top exports of Saudi Arabia are Crude Petroleum ($96.1B), Refined Petroleum ($13B), Ethylene Polymers($10.1B), Propylene Polymers ($4.93B) and Ethers ($3.6B), using the 1992 revision of the HS (Harmonized System) classification. Its top imports are Cars ($11.8B), Planes, Helicopters, and/or Spacecraft ($3.48B), Packaged Medicaments ($3.34B), Broadcasting Equipment ($3.27B) and Aircraft Parts ($2.18B).
