Job work done for unit located in sez

We have two companies...

One co. is located in SEZ where no excise duty is payble on Manufacturing and another in DTA where we have to pay excise duty

Now our co. (unit) located in DTA is manufacturing (doing job work) for co. located in SEZ, and subsequently our unit in SEZ will export those goods

My question is whether unit located in DTA can send goods without paying excise duty to SEZ

If yes then please tell the notification.
