Just been diving into some tin market data from a couple years back, and there's actually some interesting stuff worth revisiting here. Back in 2023, global tin production hit 370,100 metric tons, which was down about 2.1 percent from the year before. Pretty wild considering how tight supplies got afterward.

China absolutely dominated the tin producers game - still does really. Their output was around 68,000 MT that year, with Myanmar coming in second at 54,000 MT. But when you look at the actual refining side, the story gets even more interesting. Yunnan Tin Company was putting out 80,100 metric tons of refined tin, making them by far the world's largest tin producer in that category. That's a state-owned operation with roots going back to 1883, so we're talking serious legacy here.

The second and third spots were held by Peru-based Minsur with 31,700 MT and China's Yunnan Chengfeng Non-ferrous Metals at 21,800 MT. Minsur actually operates what they call South America's biggest tin mine at San Rafael - been running that since 1977. Malaysia Smelting was pushing 20,700 MT around that same period, up over 10 percent from their previous year, which helped them overtake PT Timah.

PT Timah's situation was pretty rough though. The Indonesian state-owned company dropped to 15,300 MT in 2023, down nearly 23 percent from 2022. They'd been dealing with some serious headwinds - corruption investigations, supply chain issues. It's a stark contrast from when they were basically dominating the market back in 2019.

The rest of the top 10 tin producers rounded out with companies like Guangxi China Tin (12,000 MT), Bolivia's EM Vinto (10,000 MT), Jiangxi New Nanshan (9,500 MT), Belgium's Aurubis Beerse (9,300 MT), and Thailand Smelting and Refining at 9,200 MT. Together, these top tin producers accounted for roughly 59 percent of global tin production.

What's worth noting is that market surplus situation in 2023 eventually flipped. By April 2024, tin prices were hitting 21-month highs as supply tightness emerged - especially with disruptions coming out of Myanmar's Wa State and Indonesia. The International Tin Association was pretty clear that improving macroeconomic conditions combined with those supply constraints would likely keep pressure on prices. Fastmarkets was calling out how global supply uncertainty, particularly from Myanmar, would probably keep supporting higher tin prices going forward.

So if you're watching commodity markets or thinking about tin exposure, understanding who the major tin producers are and what's happening with their output is pretty essential context. The consolidation at the top is real, and supply dynamics can shift pretty fast in this space.
