Global Tin Availability
House of Commons · Westminster Hall · 2 Sep 2026 · 10 speeches · Official Report
I beg to move, That this House has considered the impact of levels of global tin availability on the economy. Meur ras, Mrs Barker. It is an honour to serve under your chairship once again for such an important debate, not just for the UK’s domestic energy security but for global climate change. We were expecting more numbers when colleagues thought this was a Tinder debate, but when I explained that it was a tin debate, the numbers dropped off slightly. The ill-informed may associate tin with cans, but in fact our cans are made almost exclusively of aluminium and contain no tin. More learned colleagues will know that tin, which is used in virtually every electrical device, is increasingly indispensable in the technologies that underpin modern industries. The digital economy, the green economy and the artificial intelligence economy-tin is foundational to each. However, as with other critical minerals, the overconcentration of processing and supply among a small number of countries a long way from western Europe presents massive economic and geopolitical risks. While debates about critical minerals are often focused on lithium, tungsten, nickel and rare earths, tin is often inexplicably overlooked. I have to declare an interest, not only as an officer of the all-party parliamentary group on critical minerals but as the MP for the constituency of the last tin mine in the country to close in 1998. However, it is not only in Camborne and Redruth that the stirrings of excitement...
I thank my constituency neighbour, my hon. Friend the Member for Camborne and Redruth (Perran Moon)-the Tin Man -for securing this important debate. I would like to concentrate our focus, no pun intended, on the midstream and downstream applications of tin, of which Cornwall is the cornerstone and which is an important part of the supply chain, as well as on some of the blockers to securing the supply that my hon. Friend talked about so eloquently. That is not to say that I do not worry about the upstream mining opportunities, but it is fair to say that Cornwall’s riches are abundant on that front. Yes, there will be bumps in the road, and yes, there will be successes and failures, as there have always been in the relatively high-risk business of mining, but what I really worry about is securing midstream processing. In the case of tin, it is the crucial smelting process that will enable us to keep our supply chain onshore. I will give a brief nod to Cornwall’s other, perhaps less famous but equally important critical minerals-namely lithium and tungsten, which are under our feet today. There are many more, but it is fair to say that, as it stands today, the big three-if I can use that term-are tin, lithium and tungsten. It is imperative that, across each of those three mineral resources, where we now have absolute clarity and visibility on the security of supply upstream, we start to think about the next stage of building those supply chains. Practically, what do we believe...
Meur ras, Mrs Barker; it is a pleasure to serve under your chairship. I thank my Cornish colleague, my hon. Friend the Member for Camborne and Redruth (Perran Moon), for securing this important debate. As my hon. Friends from Cornwall know and speak about so powerfully, Cornwall has a proud mining heritage and was a key part of Britain’s first industrial revolution. We now have an opportunity to revitalise that in a way that serves our future aspirations. It is fantastic that this Labour Government have recognised that through the Kernow industrial growth fund. Local projects, such as the Cornwall Resources Redmoor tungsten and tin project, can bring crucially needed investment to areas like Callington in my constituency, as well as opportunities throughout South East Cornwall. We need to make sure that the benefits of those are felt by my local community; that means local skills, apprenticeships and good-quality jobs. I strongly believe that our young people should not feel that they have to leave the place they are from to get on in life and succeed. Tin and the mining opportunities of Cornwall are a significant factor in how we build their future hopes and aspirations. As my hon. Friend the Member for Camborne and Redruth mentioned, demand for tin is increasingly driven by electronics, AI and clean energy. South East Cornwall can contribute its natural resources and hard-working and talented people to those growing industries. I welcome the Minister’s thoughts on how the...
It is a pleasure to serve under your chairmanship, Mrs Barker. I congratulate the hon. Member for Camborne and Redruth (Perran Moon) on securing this debate. Tin is one of those materials that most people never really think about, but our everyday lives depend on it because it is the material that physically holds all our devices together, with soldering being one of its most significant uses worldwide. It joins the components on our circuit boards. It is in almost every single device, from the smartphones that we all own to the computers and data centres powering the AI revolution. This debate is not about a niche commodity; it is about a key component of our everyday lives. However, one of the problems is scale. Globally mined tin output this year will be about 294,000 tonnes, which is absolutely tiny compared with copper or aluminium. That scale is so small that the market is acutely sensitive to any disruption in any single place. The supply of tin, as we know, is extraordinarily concentrated. China is one of its largest single producers, accounting for about a third of the global tin supply, and Indonesia, Myanmar and the Democratic Republic of the Congo hold much of the rest. Several of the jurisdictions mining the majority of our tin are affected by international conflict, resource nationalism or simple geological decline, and the result, since 2025, has been the strongest price rally of any major industrial metal in the UK. The Government already recognise that,...
It is a pleasure to see you in the Chair, Mrs Barker. Thank you very much for keeping us all in order. Let me first congratulate the hon. Member for Camborne and Redruth (Perran Moon) on securing the debate. I am pleased that he clarified that it is not a debate on Tinder. To clarify, I did know that it was a debate about tin and not Tinder, but it is clear that he is a perfect match for this subject, because-I did not know this, actually-he is known as the Tin Man. Unlike in “The Wizard of Oz”, though, he does not need to search for a heart, because it is clear that he cares deeply about this subject and is a great advocate for tin and for his constituents. I very much enjoyed, and was partly educated by, his excellent speech. He will recognise elements of his speech in my own, because of the excellent points he made. Unlike lithium, tin is rarely treated to big headlines and gigafactory photo opportunities. However, as we have been hearing, it quietly plays an indispensable role in our economy. Half the tin we consume goes to electrical solder, supporting our entire electronics industry, as the hon. Gentleman pointed out so eloquently. Demand is only increasing as solar panels, electric vehicles and AI data centres compete for the same limited global supply, and it is no surprise that prices have soared to nearly $50,000 per tonne as a result. The hon. Member for Camborne and Redruth was right to highlight the new investment in the South Crofty mine as of May 2026, which...
It is a pleasure to serve under your chairship, Mrs Barker. It is also a pleasure to respond to my hon. Friend the Member for Camborne and Redruth (Perran Moon) and to congratulate him on securing this debate. It is a further pleasure to be taken back, at least momentarily, to my summer holiday in the constituency of my hon. Friend the Member for St Austell and Newquay (Noah Law). I will not say where I would rather be at this particular moment. Scientists have said that the shortest scientifically measurable period of time is 247 zeptoseconds, but I can confirm that my own research has found an even shorter measurable time than that, which is the period between someone being appointed the Minister for critical minerals and all the Labour MPs from Cornwall contacting them to ask for meetings and conversations about the potential for critical minerals in that part of the world. Perhaps appropriately for a debate on mining, they are Stakhanovian in their work effort on this issue. This debate on global tin availability is timely, as has been said. It is not always the mineral that attracts the big headlines, but to respond to the first request of my hon. Friend the Member for Camborne and Redruth, I confirm that the Government absolutely recognise that tin is central and fundamental to modern economic life. It is the solder that connects circuit boards, semiconductors, data infrastructure, automotive electrics and of course defence technologies. When global tin supply is...
I commend the hon. Member for Camborne and Redruth (Perran Moon) for securing this debate. I am sponsoring an event next door at which I had to speak, so I could not be in the Chamber, although I intended to be here. I spoke to you earlier, Mrs Barker, for permission to ask a question instead. The hon. Gentleman is a fantastic spokesman for Cornwall. He is present whenever we debate a subject that has to do with Cornwall, and I congratulate him on that. This issue is of particular significance for us in Northern Ireland, and we want to add our support for what the hon. Gentleman is doing, because we have no major domestic source of tin and rely on imported supplies, making businesses vulnerable to international supply chain disruption. Businesses in Northern Ireland also face additional complex regulatory requirements to ensure that tin is not linked to conflict or illegal mining. We in Northern Ireland want to add our support to Cornish Metals’ plans to establish production at the South Crofty mine in Cornwall, which could support the securing of a supply for the west and ensure that Northern Ireland has accessible tin at an affordable price, with no EU interference in the trade. I again commend the hon. Member for Camborne and Redruth and I look to the Minister to support him. We certainly support him in Northern Ireland.
I thank the hon. Gentleman for his offer of support for the effort. One of Northern Ireland’s key economic strengths is advanced manufacturing, and the importance of tin runs through that sector from top to bottom. Tin underpins so much: advanced manufacturing, automotive production, aerospace, clean energy technologies, data centres, telecommunications and defence, all of which are important for Northern Ireland and the UK at large. If tin is scarce, volatile or increasingly concentrated in a few countries, as hon. Members have mentioned, those pressures can affect investment confidence, productivity and our competitiveness in the sectors within the industrial strategy. It is not enough, as my hon. Friends the Members for St Austell and Newquay and for South East Cornwall (Anna Gelderd) have said, simply to leave this matter to the market. We have a responsibility to make sure that local people benefit from it. As my hon. Friend the Member for South East Cornwall also said, it is essential to our ability to deliver on the industrial strategy as a whole. Critical minerals in themselves are an essential part of the UK economy, but they also underpin everything else that we are trying to achieve. That is why the critical minerals strategy is focused on resilience, improving our understanding of demand, supporting domestic capability where it is viable and environmentally responsible, increasing recycling and working with international partners so that UK businesses are not...
I thank everybody who has contributed to this debate. Perhaps next time I should actually advertise it as a Tinder debate, and we can educate people while they are here. I will thank a few people specifically. My hon. Friend the Member for St Austell and Newquay (Noah Law) is very knowledgeable, particularly in the areas of midstream and downstream work; he talked about processing supply chains. Both he and my hon. Friend the Member for South East Cornwall (Anna Gelderd) mentioned the Kernow industrial growth fund. Right now, that fund is being used for exactly what it was designed to do-to support some exploratory mining opportunities, among other commercial opportunities in Cornwall. He also mentioned unblocking planning and permitting issues, which we need to take on board. My hon. Friend the Member for South East Cornwall is a superb champion for Cornwall Resources, which is doing amazing things to maximise the opportunity in tungsten. She talked insightfully about the local benefits, including in relation to the skills agenda. We really need to tie that agenda in with our devolution deal, which I know the Prime Minister has mentioned several times in the last 48 hours. For us in Cornwall, the skills agenda will be critical-excuse the pun-to maximise the opportunities in this particular sector. I totally agree with the Liberal Democrat spokesman, the hon. Member for Maidenhead (Mr Reynolds), about the exploration that is urgently needed on these critical minerals. I...
Sitting adjourned.
