Sell Overstock of supplies?

Is there a way a corporation can sell off overstock of supplies? I got a company that somehow wound up with 228 months supply of navy missle interceptor batteries. I didn't think you could have more than 120 months supply of anything at any given time...

From the main trading page trade with own corps
or the menu bar Trade>trade with own corps

That allows me to sell products that the company produces. I am talking about the actual supplies. The company makes defense weapons mantainence but has an overstock of navy missle batteries

Look again, I use that page almost every day to sell supplies to corps, and on it is the option to buy supplies.

Alternatively, just wait and the corp will eventually use them up.

John V, not looking to move supplies to a corp. I am looking to sell the supplies that a corp has. I do no need over 200 months of stock.

Look again.
As johnV said, you can sell supplies to the country.
