Boeing's agreement to sell 80 passenger jets to Iran may not be directly impacted by new U.S. sanctions on Tehran but the deal still could unravel, according to analysts.

President Donald Trump's administration on Friday imposed new sanctions on Iran after a ballistic missile test by the Islamic republic. The U.S. claims the missile test was a violation of a United Nations resolution.

"The Trump administration is absolutely determined to ratchet up tensions and the Iranians will of course, being hardliners there, want to do the same," said Richard Aboulafia, vice president of analysis at Virginia-based industry consultancy Teal Group.

In December, Boeing announced an agreement for Iran Air, the country's flag carrier, to buy 50 of its narrow-body 737 passenger jets and 30 of the wide-body 777 aircraft. The aircraft manufacturer valued at the deal at $16.6 billon, based on list prices for the planes.

Industry observers suggest Tehran could pull out of the Boeing deal if tensions continue to worsen. Besides the new sanctions, Trump's travel ban against Iran and six other majority-Muslim countries also drew criticism from Tehran and vows of retaliation.

Besides the airplane sale, the Boeing deal involves aircraft maintenance services as well as ongoing support with spare parts on the jets.

"It's a risk, but not something that will overwhelm [Boeing]," said Moody's analyst Russell Solomon, who covers the aerospace and defense industry. "They do have a tremendous amount of operating and financial flexibility because of strength of the balance sheet, a strong liquidity profile and a very significant order book."
