National Audio Company also says the only factory mining the material has been under renovation for most of 2019.
According to a letter from NAC to tape label Hausu Mountain Records, the company attributes the delay to a worldwide shortage of high grade gamma ferric oxide, a material used to manufacture cassettes, Pitchfork reports. The NAC says the only factory mining the material has been under renovation for most of the year, which has resulted in it only receiving "two tons of recording oxide" in 2019, while they wait on "back-orders of more than 50 tons of gamma ferric oxide."
NAC says it will receive at least 11 tons of oxide in October, when it hopes to resume scheduled deliveries.

Some of the cassette manufacturing people that I've talked to about this haven't gotten this letter. I think it's probably good for all to see.— Hausu Mountain (@HausuMountain) October 9, 2019
