According to Bloomberg, crude from Iran stored in tankers offshore Asia is a potential option given that it can be delivered quickly.
Chinese independent processors usually seek to use up quotas so they can apply for comparable volumes in the next year, the financial news provider said.
There are millions of barrels of crude floating off China and around Singapore and Malaysia that include Iranian oil.
Iran's new Minister of Petroleum Javad Owji said last month that "good things will happen in terms of oil sales in the coming months".
The US imposed its most draconian sanctions on Iran three years ago with the express aim of bringing the country's oil exports down to zero after Washington abandoned an international nuclear deal with Tehran.
No matter how hard it tried, the US did not achieve its goal and Iran continued sending its oil to the market – though in reduced volumes - using innovative ways to bypass the illegal sanctions.
However, the "tyrannical" US sanctions deprived Iran of 1.8 billion barrels of oil exports and more than $100 billion of revenues, Owji told the first OPEC Plus meeting since being named to the new post.
Oil markets are closely watching Vienna negotiations which have been suspended since mid-June, for any clues as to when the OPEC member will be able to resume crude sales.
Owji has said Iran will return to its pre-sanctions crude production level as soon as the US sanctions are removed. Petroleum ministry officials have said they are confident most output could be restored within a month.
Iran's LPG exports are already hovering near two-year highs at around 500,000 tonnes a month.
Last week, S&P Global Platts said Iran's LPG shipments are set to reach around 440,000-450,000 tonnes in October compared with 556,000 tonnes exported in September, and they are expected to rebound in November.
"The export volume in October will be lower in comparison to September. The export volume is fluctuating between 450,000 tonnes a month and 530,000 tonnes a month," it quoted a trade source as saying.
"November will be estimated to be the same as September in case we don't face shutdowns."
Platts also quoted Chinese sources as saying that more Iranian LPG was shipped to China this year due to the grade's competitive price.
