The PanStar Acro returned to Busan on October 11 after a 50-day round trip to Europe through Russia's Arctic coast2. The container ship left Busan on August 22 and called at Felixstowe, Rotterdam and Gdansk before sailing back along the Northern Sea Route4.
The operator, Panstar Line.com Co., used a 2,758 TEU ship1. The government-backed trial carried billed export cargo, but only 737 loaded TEU of a planned 1,300 TEU2.
Korea's Ministry of Oceans and Fisheries said the vessel reached Felixstowe in about 20 days2. President Lee Jae Myung said the voyage cut one-way sailing time by 10 days against the Suez Canal route2. Deutsche Welle reported a saving of at least 10 days on the round trip against the fastest Suez timings4. The Northern Sea Route is about 7,000 km, or 4,350 miles, shorter4.
Seoul wants a scheduled service by 2030
The Lee government wants regular commercial services on the route by 2030 and treated this voyage as a logistics test4. The Oceans and Fisheries Ministry plans to analyse the results before preparing more trials2.
Joseph Kristanto of Singapore's S. Rajaratnam School of International Studies said the route could lower shipping costs and transit times and strengthen Busan as a maritime hub4. He also warned that it "could introduce a new form of strategic dependency on Russia as Moscow exercises considerable control over navigation along its Arctic coastline"4.
Traffic is growing, from a small base. The Arctic Council counted a record 1,812 vessels operating in the Arctic last year, 40% more than in 20134. The Northern Sea Route logged 104 confirmed transit voyages by the end of September, already above the 103 recorded in all of 20255. Transit cargo is estimated at 3.7 million tonnes, up 15% from a year earlier. The Centre for High North Logistics expects close to 150 transits and 4.5 million tonnes for the season5.
Containers remain a footnote. Crude and bulk made up roughly 86% of transit cargo, and Asia-Europe container transits rose from one in 2025 to four by the end of September5. Russia is also preparing regular year-round eastbound sailings from early 2027, Rosatom Arctic Directorate head Vladimir Panov said6.
The cost gap is the real test
The shorter distance does not translate into a cheaper slot. The Loadstar modelled a 4,900 TEU ship on eight seasonal sailings and found a slot costs about twice a Suez slot at October charter and bunker prices with half-full ships3. Icebreaker escort adds $150,000 to $280,000 a transit, and Chinese sources put Arctic hull and protection and indemnity cover at three to five times normal rates3.
Physical limits also bind. A 12.5 metre draught limit in the Sannikov Strait caps containerships at roughly 5,000 TEU, and ships without a high ice class have a three-month window in a good year3. Under the IMO Polar Code, a ship needs a Polar Ship Certificate, a Polar Water Operational Manual and trained officers7.
The only scheduled container product so far is Chinese. Sea Legend ran eight weekly sailings this season with seven ice-strengthened ships, the largest 4,890 TEU5. Container News said the service competes with rail and air-sea for time-sensitive peak-season cargo, not with Suez mainline services5.
Moscow sets the terms
Every voyage needs a permit from Rosatom's NSR Administration, which also sets the route and the escort, and Rosatom manages the route in 28 sections3, 5. Panov said the route "is one step away from regular shipments in the eastern direction"6.
Western carriers have stayed away. Atomflot, the icebreaker operator, has faced US sanctions since 2023. MSC, CMA CGM and Hapag-Lloyd have all said they will not use Arctic routes, and Cosco has stayed out since 20223. The European Commission adopted a new Arctic strategy on October 20 with security and resilience as its first priority8. Lee said Seoul would pursue the route in "strict compliance with sanctions"1. Deutsche Welle reported that European diplomats' concerns include the alleged delivery of around 165,000 tons of fuel to Russia aboard sanctioned tankers in August4.
What would change the case for buyers
Two things would move the economics: capacity and tariffs. The Loadstar reported that a new escort tariff order is in draft, and that Russia's transport ministry proposed a per-tonne levy on exporters in September to fund two more icebreakers3. The delivery of the Rossiya nuclear icebreaker, flagship of the year-round plan, has slipped from 2027 to the end of 20293.
The alternative is also getting better. Lloyd's List Intelligence counted 2.19 million TEU through the Suez Canal in a month, the most since the Houthi campaign began3. Linerlytica expects carriers to be fully back to Suez in the first quarter of 20273. A restored Suez service would be cheaper, year-round and free of Russian permits.
Next season will show whether the Arctic lane can compete when Suez is open. The tests are whether Sea Legend can fill its ships, what Russia's new tariff costs foreign transits, and whether Cosco returns3.
