Sorry, I forgot an important part of the sentence! Actually, it's essential to mention that this production will end soon. So basically I need one sentence expressing this:
There are certain products which have already been declared end-of-life, but at the moment, they're still being produced. But these productions will expire (?) soon.
Usually when a product is declared "end-of-life," that means that there is no warranty or support as of that moment in time. These products are usually superseded by a later version or model, and customers may be offered a trade-in.
There can be an "end-of-life" date given in the future, for example, the products manufactured today will no longer be warrantied or supported after Dec. 31
