What Hammond does

Hammond Group, Inc. is a US-headquartered, employee-owned (ESOP) specialty chemicals manufacturer founded in 1930, focused on performance additives for lead-acid batteries. The company produces negative-plate expanders (over 120 proprietary formulations), lead oxides, and specialty chemical blends, including branded platforms such as LIGN3X™, GravityGuard™ and Treated SureCure®.

Operations span three manufacturing sites — Indiana (headquarters and a dedicated Treated SureCure® line commissioned in 2023), Pottstown, Pennsylvania, and Gateshead, United Kingdom — together with a Malaysian plant acquired in 2015 (Asia Litharge Sdn Bhd) and sales offices in São Paulo and Dubai. Distribution reaches 80+ countries through a partnership with Sorfin, and the company holds IATF 16949 automotive quality and ISO 9001 certifications.

The business model is B2B specialty chemicals sold into battery OEMs, with the principal customer base including Exide Industries, Trojan Battery, East Penn Manufacturing, Gridtential Energy and Black Diamond Structures. Revenue is generated through volume-based supply contracts and qualified specialty formulations sold into automotive starting-lighting-ignition (SLI), motive power, UPS/telecom standby, and energy storage applications. The company has begun positioning for next-generation chemistries through a technology partnership with Gridtential on Silicon Joule biplates, while maintaining its core in incumbent lead-acid expander chemistry.
