China's ethane imports from the US hit a record high as Iran war reduces rival feedstock supplies

According to traders, analysts, and shipping data, China increased U.S. Ethane imports in April, capitalising on the strong petrochemical margins, as other Middle East?feedstocks were disrupted by the Iran War.

The U.S. and Israel war against Iran halted the majority of shipments of liquefied gas (LPG) from the Middle East via the Strait of Hormuz. This forced Chinese petrochemical manufacturers to look to the United States to get more supplies.

This was despite the fact that trade tensions last year caused Beijing to temporarily impose a tariff of 125% on U.S. exports.

Data from Sublime China Information and?Kpler showed that China imported the highest amount of ethane ever in April. This was mainly due to purchases made by Satellite Chemical, Wanhua Chemical, and SP Chemical.

The companies did not immediately respond to requests for comment.

Kpler data showed that China's ethane exports to the U.S. have reached 3.462 millions tons, which is more than half the volume of 2025.

Kpler data shows that China's imports of naphtha, LPG and other petrochemicals almost halved in April to 1.834 millions tons. Ethane, LPG and naphtha are the building blocks of petrochemicals that are used to manufacture plastics, paints, and pharmaceuticals.

HIGH MARGINS FOR ETHANE CRACKS

According to the pricing agency Argus, the ethylene gross spot-cash margin for ethane based crackers was $845 per ton in Northeast Asia on April 3. This is the highest level since June 2018.

Manish Sejwal is senior vice president of Rystad Energy's commodity markets, oil. He said that competing crackers in China and other parts of the region were operating at lower rates or shut down due to the?tight availability of feedstock from the Middle East.

According to Chinese consultants JLC and Energy Aspects, China's crackers that use ethane operated at nearly full capacity in April.

A source from a cracker operator in Shanghai said that unlike other feedstocks, the ethane is readily available because it's sourced?from America. The source refused to give his name as he wasn't authorised to talk to the media.

The United States is the largest producer and exporter in the world of ethane. This is a by-product of natural gas. Data from the Energy Information Administration shows that China is responsible for almost half of all U.S. imports.

SCI data as of May 9 showed that imports in May are expected to drop to 414,000 tons - 41% less than April - as the domestic demand is weakening.

Toong Shien Lee said that the ethylene demand in May has weakened due to buyers of ethylene based products being concerned about shrinking margins.
