"of its nails" meaning

Hey there,

I read a news article from New York Times and notice a phrase "of its nails" that confuses me. The context is "But farmers are not the only ones suffering because of the tariffs. The Mid Continent Nail Corporation in Poplar Bluff, Mo., which ships in steel from Mexico, warns it is 'on the brinks of extinction', after being forced to raise the price of its nails. It has lost half of its orders and has laid off 60 of its 500 workers."

Could anyone explain the meaning of "of its nails" in this context?

Thanks!
