With his truck fully laden with vegetable oil, driver Mustafa Demir makes his regular trip to the Syrian border from Turkey to sell to rebels desperate for provisions as war closes off normal trade channels.
"There is so much demand from the Syrian side. There is demand for everything. Last time I was carrying paper napkins," he said.
Every day, hundreds of trucks piled high with goods ranging from cooking oil to cement and nappies form queues stretching for miles at Oncupinar, now a bustling hub for trade with Syria.
The war economy means canny traders can set up their own commodity deals to fit local circumstances and the black market is unlikely to be much disrupted by any foreign air strikes directed at President Bashar al-Assad.
In the chaos of a war that has cost more than 100,000 lives and forced millions to flee their homes, smugglers, middlemen and small companies working with shipping agents are finding ways to do profitable business, operating from neighbouring countries such as Lebanon. "Whoever is going to trade to Syria is going to make a profit because of the risks and the war. The Syrians realise that is the only way they can get their goods," said a West Asia-based source active in the commodities trade with Syria.
The worsening conflict and increasing payment problems that suppliers face in deals with Syria mean big international companies are increasingly wary of the trade.
"What we are seeing is the emergence of the smaller companies who are driving this trade now," a European based shipping source said.
"Ship owners do not want to take the insurance risk of bringing in ships to Syria. What we are seeing is suppliers delivering goods to ports like Turkey's Mersin and then local companies handle it from there." While much of the black market trade involves buyers in rebel-held areas, the Syrian state is still trying to procure goods.
Trade sources say any state related efforts to pick up supplies are likely to be less organised than they were when tenders were formally held. But they still offer price premiums for suppliers looking to sell to buyers
