What Kennametal Inc. told the SEC could break it.
Kennametal's risks trace to the critical minerals at the heart of its cutting tools and carbide products. Its major raw materials are tungsten ore concentrates, scrap carbide and cobalt, most sourced abroad — minerals with concentrated, foreign-dominated supply that have been targets of export controls — so a supply disruption or export restriction would directly raise input costs and threaten production. As a globally sourced and globally manufacturing industrial company (60% of sales outside the US), it is also exposed to tariffs, which had an unmitigated net effect of about $4 million in fiscal 2025 and which it counters with surcharges and rerouted supply chains. A longer-tail regulatory risk is that hard-metal dust from tungsten and cobalt, under study in the US, Europe and Japan, could be classified as hazardous, raising compliance and liability costs.

In its own words
What could break it.
Regulatory & policy
- U.S./global tariffs — quantified ~$4M unmitigated net effect in FY2025; mitigating via surcharges and rerouted supply chainsmedium
As a globally sourced and globally manufacturing industrial company (60% of sales outside the U.S.; plants across Germany, India, China and elsewhere), Kennametal is directly exposed to evolving trade policy and tariffs. It quantifies the impact: the unmitigated net effect from increased tariffs was approximately $4 million during fiscal 2025, and it has responded with tariff-mitigation actions including surcharges on certain product sales and, where appropriate, rerouting internal supply chains. Further tariff escalation could decrease demand, raise input costs faster than pricing/sourcing can offset, and increase impairment risk. A concrete, quantified, already-incurred trade-policy cost channel.
“The unmitigated net effect from increased tariffs was approximately $4 million during fiscal 2025.”
- Potential hazardous classification of hard-metal (tungsten/cobalt) dust under evolving health & safety regulationlow
Kennametal's core products contain hard metals — tungsten and cobalt — and hard-metal dust is under study for potential adverse health effects by regulatory and scientific bodies in the U.S., Europe and Japan. If future studies lead to classification of its products (or their manufacturing dust) as hazardous, Kennametal could face increased compliance, manufacturing, handling and product-liability costs, or restrictions on certain products. This is a distinct regulatory tail risk tied specifically to the materials that define its product line, separate from the tariff and raw-material-sourcing channels.
Commodity & input dependence
- Tungsten ore concentrates, scrap carbide and cobalt — major raw-material sources located abroadmedium
Kennametal's cutting tools, carbide inserts and metallurgical powders are built on a defined set of critical metallurgical inputs — tungsten ore concentrates and scrap carbide (to make tungsten oxide) plus cobalt as a secondary binder material. It discloses that its major sources for these raw materials are located abroad, which matters acutely because tungsten and cobalt are critical minerals with concentrated, China/foreign-dominated supply and have been targets of export-control actions. The company partially mitigates via long-term supply agreements, spot purchases, internal tungsten recycling, and an owned tungsten-concentrate operation in Bolivia, but a foreign supply disruption or export restriction on tungsten/cobalt would directly raise input costs and threaten production. A specific, named critical-mineral dependence.
“Our major metallurgical raw materials consist of tungsten ore concentrates and scrap carbide, which are used to make tungsten oxide, as well as compounds and secondary materials such as cobalt.”
