Online stores and local wellness shops favor amber glass bottles. They block light to protect oil formulations, and glass feels more trustworthy to buyers compared with plastic. Amber is the most popular color in the US market, followed by clear and blue. Green and black are less common. We offer custom spray coating with a 5000pcs MOQ. Logo printing and label production are also available as our supporting services.

Different needs of buyers across the US

Buyers from different states have different concerns, which overseas suppliers often overlook. Buyers on the West Coast mostly sell tinctures and clean beauty oils and need to follow Prop 65 labeling and local recycling rules. Northeast customers focus on herbal drops and pharmacy skincare products and prioritize consistent bottle dimensions and stable quality. Sellers in the South mainly carry massage oils and pet care liquids, worrying about product degradation from heat and light in warehouses. Midwest buyers supply wholesale DIY kits and care more about cost and standard carton fit. California has stricter regulations. Even if the glass itself is safe, rubber gaskets and printing ink on caps may require extra warning labels.
