Is astrology immoral?

I have a business and purchase soaps/lotions from a local wholesaler. With my recent order, I noticed that they changed their labels to feature a crescent moon with a face (the moon is a C-shape with the face looking east) and stars all over. I didn’t like the looks of the moon – it seemed like an astrology symbol or the like. I searched the Internet but couldn’t find an answer. Could someone tell me if this is a bad/pagan symbol? I don’t want to sell the products if it is something bad.

Your title question is entirely different from the particular problem that concerns you. Let’s look at them separately:

The Catechism of the Catholic Church affirms that the practice of astrology constitutes grave matter:

All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to “unveil” the future. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone (CCC 2116).

But astrology per se is not the problem you’re facing. According to your account, you received a shipment of soaps and lotions with packaging labels decorated with a moon and stars. Label decorations with motifs drawn from nature are harmless in and of themselves, so there doesn’t appear to be reason to worry unless the package itself contains materials (e.g., an informational insert) directly promoting astrology.
