• Albemarle for antimony.
• Freeport-McMoRan for antimony.

• Antimony Metal: A metalloid used primarily in alloys to harden other metals, particularly lead, and in batteries, chemicals, and semiconductors.
• Antimony Trioxide: A flame retardant additive used in plastics, textiles, adhesives, and coatings.
• Antimony Sulfide: Used in friction materials, pigments, and as an ingredient in some specialized products.

United States Antimony (UAMY) primarily sells its antimony products, which are raw materials and intermediate goods, to other industrial companies rather than directly to individuals. Due to the nature of their business and typical disclosures in public filings (such as their 10-K reports), UAMY generally states that no single customer accounts for 10% or more of its revenues. This means there are no individually named "major customers" that are legally required to be disclosed.

Instead, UAMY serves a diversified base of industrial customers who utilize antimony in various manufacturing processes. The major categories of companies that purchase antimony, and thus represent UAMY's customer base, include:

1. Chemical and Material Manufacturers for Flame Retardants: These companies incorporate antimony trioxide as a synergist in halogenated flame retardant systems used in plastics, textiles, rubber, and coatings to meet fire safety standards.
2. Lead-Acid Battery Manufacturers: Antimony is alloyed with lead to improve the mechanical strength, corrosion resistance, and cycling stability of lead-acid battery grids, which are widely used in automotive, industrial, and backup power applications.
3. Specialty Alloy and Metal Producers: Companies that produce alloys and specialized metals use antimony as a hardening agent for lead, tin, and other metals, enhancing properties for applications such as bearings, solders, and ammunition.

One clear emerging threat for United States Antimony (UAMY) is the accelerating global transition to electric vehicles (EVs). Antimony is a key alloying agent in lead-acid batteries, primarily used in internal combustion engine (ICE) vehicles for starting, lighting, and ignition (SLI) functions. As the automotive industry shifts rapidly towards EVs, which utilize lithium-ion batteries that do not contain antimony, the long-term demand for antimony in this significant end-use market faces substantial decline.

Another emerging threat is the increasing market and regulatory pressure to develop and adopt non-antimony flame retardant solutions. Growing environmental and health concerns associated with certain traditional flame retardant chemistries, some of which use antimony trioxide synergistically, are driving industries to reformulate products and seek alternative materials. This trend could erode demand for antimony in one of its primary applications, particularly in consumer goods and specific industrial sectors.
