Danny K,
As JOAnne said, the requirements depend greatly on the intended use. If the alcohol swabs are intended to be used to disinfect a person's skin (prior to injection, for example), then the FDA requires 510(k) clearance, even though the device is unclassified.
So if this is your intended use, you would need to obtain 510(k) clearance and also comply with the general controls (e.g., 21CFR 820 and regulations for Labeling, Recalls, and MDR reporting).
