Zinc, lead, and tin — direct from Latin America's top mining regions

Zinc, lead, and tin are base metals critical to industrial supply chains across the United States and Latin America. Zinc is primarily used for galvanizing steel to prevent corrosion, as well as in die-casting alloys and brass production. Lead remains essential for lead-acid batteries, radiation shielding, and certain chemicals, while tin is indispensable for soldering in electronics, tinplate for food packaging, and specialty alloys. Together, these metals form a commodity cluster that supports construction, automotive, energy storage, and consumer goods manufacturing. The trade flow between the US and Latin America for these metals is substantial, with the US importing significant volumes of refined zinc and lead from Peru, Mexico, and Bolivia, while exporting scrap and concentrates for processing. For US buyers and Latin American suppliers, navigating the price volatility, quality specifications, and logistics of zinc, lead, and tin requires a trusted advisory partner with deep regional expertise.

Products and Grades in This Cluster

Zinc, lead, and tin are traded in multiple forms, each with distinct specifications that affect pricing and end-use suitability. Zinc is commonly traded as Special High Grade (SHG) zinc ingots, with a minimum purity of 99.995%, used primarily for galvanizing and alloying. Other grades include Prime Western (PW) zinc, which contains up to 1% lead and is used for less demanding applications, and zinc alloys such as ZAMAK for die casting. Zinc concentrates, typically containing 50-60% zinc, are also traded for smelting. Lead is most often traded as refined lead ingots with 99.97% purity for battery manufacturing, along with lead alloys and lead scrap (such as used batteries) for recycling. Tin is traded as Grade A tin ingots with 99.85% minimum purity, used in solder and tinplate, as well as tin concentrates and secondary tin from recycling. Each product form requires careful specification verification, including chemical composition, impurity limits, and physical dimensions, to meet US import standards and buyer requirements. For example, SHG zinc must pass ASTM B6 standards, while tin for electronics must comply with RoHS directives on lead content.

LATAM and Africa Suppliers: Production and Scale

Latin America is a major global source of zinc, lead, and tin. Peru is the second-largest zinc producer in the world, with mines such as Antamina and Cerro Lindo producing over 1.4 million metric tons of zinc concentrates annually. Mexico is a leading producer of both zinc and lead, with operations like Peñasquito and Fresnillo contributing significant output. Bolivia holds some of the largest tin reserves globally, with the Huanuni mine and the state-owned Empresa Minera Huanuni producing around 20,000 metric tons of tin concentrates per year. Brazil also produces zinc and tin, with the Masa and Rondônia regions active in tin mining. In Africa, the Democratic Republic of Congo and South Africa produce zinc and lead concentrates, though volumes are smaller compared to Latin America. The scale of production varies widely: Peru and Mexico together account for roughly 15% of global zinc mine production, while Bolivia supplies about 5% of global tin. For US buyers, these regions offer competitive pricing and established export infrastructure, though quality consistency and supply chain reliability can vary by country and season. Coppermont’s network of vetted suppliers across these countries helps buyers secure consistent volumes of SHG zinc, refined lead, and Grade A tin, with transparent pricing and logistics support.

US Buyer Types: Who Buys and What They Need

The primary buyers of zinc, lead, and tin in the US span several industries. Galvanizers and steel mills purchase SHG zinc to coat steel coils and sheets for construction and automotive applications. Major US galvanizers include companies like Nucor and US Steel, which require consistent monthly volumes of several thousand metric tons. Lead-acid battery manufacturers, such as Clarios and East Penn Manufacturing, are the largest consumers of refined lead, using it for automotive and industrial batteries. They procure lead ingots and scrap on long-term contracts, often specifying purity above 99.97% and low antimony content. Electronics manufacturers and solder producers buy Grade A tin for soldering pastes and bars, with demand tied to the production of circuit boards and semiconductor packaging. Tinplate producers for food cans also require tin with tight impurity limits. Additionally, trading houses and metal distributors act as intermediaries, sourcing from Latin American smelters and selling to end-users across the US. These buyers typically seek long-term supply agreements with fixed quality specifications, competitive pricing based on LME or COMEX benchmarks, and reliable delivery schedules. Procurement teams also prioritize suppliers with strong environmental and social governance practices, as downstream customers increasingly demand sustainable sourcing.

Certifications and Compliance for This Cluster

Importing zinc, lead, and tin into the US requires adherence to several regulatory frameworks. The US Environmental Protection Agency (EPA) regulates lead under the Toxic Substances Control Act (TSCA), requiring importers to certify compliance with lead content limits in certain products. Tin and zinc are subject to general import regulations, but specific end uses may require additional certifications. For example, tin used in food-contact tinplate must meet FDA standards for metal migration. Zinc and lead concentrates may be classified as hazardous materials under DOT regulations if they contain certain levels of arsenic or cadmium, requiring special handling and documentation. Importers must also comply with US Customs and Border Protection (CBP) rules on country of origin, tariff classification under HTS codes, and antidumping duties that may apply to certain countries. Certifications such as ISO 9001 for quality management and ISO 14001 for environmental management are increasingly expected by US buyers. For tin, the Conflict Minerals Rule under Section 1502 of the Dodd-Frank Act requires due diligence on supply chain sources to ensure tin is not from conflict-affected regions like eastern DRC. Latin American suppliers from Peru, Mexico, and Bolivia generally have strong compliance records, but US buyers should request certificates of analysis (COA) for each shipment, along with smelter audits for tin. Coppermont assists buyers and suppliers in navigating these compliance requirements, ensuring documentation is complete and shipments clear customs without delays.

How Coppermont Advisory Works for This Sub-Sector

Coppermont provides end-to-end trade advisory services for zinc, lead, and tin between the US and Latin America. For US buyers, our team identifies and vets suppliers in Peru, Mexico, Bolivia, and other producing countries, conducting site audits and verifying production capacity, quality control processes, and export capabilities. We negotiate contracts that align with LME pricing, specify quality parameters, and include force majeure and arbitration clauses suited to cross-border trade.
