Both parties have reached a consensus on cross-border overseas delivery for the marine oil and see the move as an "important foundation" for China's first futures delivery "going global", Shanghai Futures Exchange-owned INE said in a statement.
This would be the first time a Chinese futures contract would be deliverable outside of China, which could boost the liquidity and increase the pricing influence of the low-sulphur fuel oil contract.
Reuters reported last week citing sources that the INE was considering using PetroChina-owned oil storage sites in Singapore as a delivery point for its low-sulphur fuel oil futures contract.
INE's statement did not specify where the storage sites or delivery points would be, but mentioned that PetroChina had distribution centres for bonded marine fuel oil domestically in the eastern port city of Zhoushan, as well as overseas in Singapore and the UAE.
China launched its low-sulphur fuel oil futures contract in June, following a ruling by the International Maritime Organization (IMO) which banned ships from using high sulphur content fuel oil this year unless equipped with exhaust scrubbers.
The contract launch and the move to enable overseas delivery could help boost China's ambition to build a regional bunkering hub in Zhoushan to rival Singapore, which is the world's biggest ship-fueling port.
