Chinese Refiners Turn to Prompt Saudi and Iraqi Crude as Gulf Shipping Risks Rise

Chinese refiners are responding to the disruption by buying barrels that are available now, fit complex refinery systems and can still be moved through a workable logistics chain. PetroChina, Sinochem Group, Unipec and Rongsheng Petrochemical reportedly bought about 10 million barrels of Saudi Arab Medium and Arab Heavy crude in a rare tender, while Rongsheng and state-run processors purchased at least 8 million barrels of Iraq’s Basrah Heavy and Basrah Medium for prompt delivery.

The pattern is more than simple bargain hunting. It shows that Chinese buyers are shifting from a normal supply strategy—built around term contracts and predictable Gulf routes—to a prompt-market strategy in which loading access, tanker availability and delivery risk are central to the value of each cargo.

The buying response: secure compatible grades first

Saudi Arab Medium and Heavy and Iraq’s Basrah grades are medium-to-heavy crudes that can serve refiners seeking alternatives to disrupted Gulf or Iranian supply. The reported purchases give Chinese processors near-term physical coverage without waiting for normal monthly nominations to stabilize.

This approach is also visible among China’s independent refiners, often called “teapots.” In July, Reuters reported that independent processors bought 16 million to 20.5 million barrels from Qatar, Iraq and the United Arab Emirates—their largest purchases of non-sanctioned Middle Eastern oil since the conflict began, according to traders.

The transactions do not mean supply conditions have returned to normal. Some Chinese refiners reportedly reduced or skipped Saudi term nominations for August amid weak domestic demand, competition from other producers and continuing Hormuz disruption.

Iraq offers barrels, but not a dependable bypass

Iraqi crude continues to leave the Gulf through the Strait of Hormuz, making Iraq a partial release valve for Asian buyers. But that route remains exposed to security threats, insurance constraints and limited tanker availability. Iraq’s southern exports also have few practical alternatives if the strait becomes unusable; its production fell to about 1.9 million barrels per day in June from 4.2 million barrels per day in February, according to reporting cited by CNBC.

That makes Iraqi Basrah attractive as a prompt cargo but difficult to treat as a fully reliable replacement for missing regional supply. A barrel can be available at the wellhead and still be commercially unavailable if it cannot be loaded, insured or transported on schedule.

China’s July import rebound was real—but incomplete

China’s crude arrivals recovered in July after reaching a near-decade low in June. Reuters put July arrivals at 8.41 million barrels per day, up from 7.12 million barrels per day in June, but still 24.3% below July of the previous year.

Broader Asian crude and fuel imports also improved to 22.82 million barrels per day in July, the highest level since the conflict began. Even so, that total remained about 15% below the 26.89 million barrels per day average recorded in the three months before the conflict.

The rebound therefore indicates that some flows resumed and that refiners found alternative suppliers—not that the original Gulf trading system was restored. Gulf crude and condensate exports remained about 40% below pre-war levels in July.

Fewer ships make route optionality more valuable

Shipping data illustrates the scale of the logistical constraint. Only 33 vessels transited Hormuz from Monday through Thursday in the week cited by Reuters, compared with 50 in the comparable period a week earlier. Just six crude oil tankers had exited the strait during that week.

The Red Sea created a second layer of risk. After an attack on Saudi oil installations, traffic through the Bab el-Mandeb fell to 11 commodity vessels on one Sunday—the lowest level in months, according to Kpler data reported by Reuters.

For refiners, this changes the economics of a cargo. The relevant question is no longer only whether the crude is cheap or refinery-compatible. Buyers must also assess whether it can leave the loading area, which route it will take, whether insurers and shipowners will accept that route, and how much delay risk is embedded in the price.

Saudi Arabia is using its pipeline and Red Sea options

Saudi Arabia has more alternatives than Iraq because its East-West pipeline can move crude from the Gulf to Yanbu on the Red Sea. Yanbu export volumes approached 2 million barrels per day during the initial disruption, although that was insufficient to replace all the Saudi volumes normally shipped through Hormuz.

From the Red Sea, Saudi cargoes can head toward Asia through the Red Sea and Suez Canal. The system is operationally complicated: fully loaded supertankers cannot pass through the canal, so some cargoes use the Sumed pipeline between Ain Sokhna and Sidi Kerir before being reloaded in the Mediterranean.

That route is not risk-free. Ships carrying Saudi crude have reversed course after attacks and threats around the Red Sea, showing that bypass capacity does not automatically translate into secure deliveries.

Saudi Aramco has also explored ship-to-ship transfers off Fujairah in the UAE to offer Arab Medium and Arab Heavy cargoes outside the most exposed part of Hormuz. The move underscores how producers and buyers are assembling flexible, cargo-by-cargo solutions rather than relying on one normal export route.

ADNOC’s tenders turn logistics into a market price

Abu Dhabi National Oil Company has repeatedly offered Upper Zakum, Umm Lulu and Das crude through spot tenders. These grades originate in the Gulf, so the tenders give Asian refiners access to physical supply while testing whether buyers are willing to accept the associated loading and transport risks.

ADNOC sold at least 30 million barrels of spot crude to Asian refiners and trading firms in June, according to Reuters reporting, and sold at least another 12 million barrels in a late-July tender.

The tender mechanism gives buyers flexibility over timing and delivery arrangements, while allowing ADNOC to move barrels despite uncertainty around the waterway. Later tenders also offered options such as free-on-board lifting at UAE locations or ship-to-ship transfers, according to trade reports.

Reports have described premiums for some ADNOC cargoes, while other tenders featured deep discounts as producers competed to clear supply. The conflicting pricing signals matter: there is no single “Hormuz premium.” The value depends on the grade, loading point, delivery basis, route, timing and perceived security of the cargo.

What the transactions reveal about the oil market

Three conclusions stand out:

1. Prompt supply has strategic value. Chinese refiners are willing to buy large volumes quickly when cargoes match refinery needs and can be delivered, even while overall demand and imports remain weak.
2. Iraq is more exposed than producers with bypass infrastructure. Continued Iraqi exports show that Hormuz is constrained rather than entirely devoid of traffic, but Iraq’s dependence on southern Gulf terminals leaves it vulnerable to another deterioration.
3. The market is pricing transportability, not just crude quality. Saudi pipeline diversions, ship-to-ship transfers and ADNOC tenders all show that route optionality has become part of the barrel’s commercial value.

The bottom line

Chinese refiners are keeping their plants supplied through a combination of prompt Saudi and Iraqi purchases, non-sanctioned Middle Eastern alternatives and opportunistic spot tenders. China’s July import rebound confirms that some supply has returned, but the country and the wider Asian market remained well below pre-conflict levels.

Gulf oil is still reaching Asia, but through a less efficient and more fragmented system: selective Hormuz passages, Saudi pipeline-and-Red-Sea rerouting, ship-to-ship transfers and repeated UAE tenders. Until vessel traffic, insurance access and export routes normalize, dependable logistics—not crude quality alone—will determine which barrels Chinese refiners are prepared to buy.
