Ulaanbaatar, November 25, 2025 /MONTSAME/. Customs authorities in Erenhot, the People’s Republic of China, currently hold 8,000 tons of semi-coke, while the “Tavan Tolgoi Tulsh” LLC’s plant has stockpiled 35,000 tons of fuel.
Trains transport 2,200-4,400 tons of fuel daily from these reserves to Ulaanbaatar. An independent laboratory and the control authorities of both countries monitor the fuel quality. The Governor’s Office of the Capital City of Ulaanbaatar reported that China has committed to delivering 306,000 tons of semi-coke briquettes without disruption this winter.
Introducing semi-coke briquettes into use can halve sulfur, nitrogen oxide, and particulate emissions. The fuel meets technical specifications set according to international standards, and the joint, accredited CCIC laboratory verifies its quality. Laboratory tests show that the semi-coke briquettes have a moisture content of 6 percent, an ash content of 20 percent, a volatile matter of 12 percent, and a sulfur content below 0.5 percent. Based on these results, customs clearance is completed under Erenhot inspection, and samples are also checked by Mongolian customs laboratories.
To date, China has widely exported over 90,000 tons of semi-coke briquettes to Mongolia. B. Ulziibat, Deputy Head in charge of cargo at the Zamiin-Uud station, said that four private companies participate in wagon transport. We receive cargo from the Erenhot station according to documentation, promptly process it, and load it onto trains, and the transport company handles customs clearance, delivering it to the Bayan station under local documentation. In terms of timing, customs clearance at Zamiin-Uud takes 4–5 hours, transport to Bayan station takes 24 hours, and unloading takes 24–48 hours. From there, it is transported to the Choir station in one day. Loading and delivery cycles take 2–3 days, and a full rotation of a single checkpoint takes 5–7 days.”
