Maybe I'm missing the point of the question, but my understanding is that for the foreseeable future CTD can sell and ship product just as they do now.
When the volume of shipments gets large enough that they need someone else to fulfill orders, that will be a sign of success.
To name one company, Johnson & Johnson has been involved with the Hempel trials. Maybe they will want to ship for CTD - or better yet, just acquire CTD outright. $50 million might do it. That's about $1.70/share.
