About Metal Cap Supply

Metal Cap Supply is a U.S.-based metal closure supplier serving supplement, food, beverage, cosmetic, pet food, and candle brands. We focus on a curated range of standard closure types, in-stock sizes from 38mm to 110mm, and reliable domestic warehousing.

We exist because most brands sourcing metal closures end up navigating overseas suppliers, long lead times, and inconsistent quality. We give you a contact who understands your product category and gets you the right closure quickly.

Every account works with a dedicated contact who can help match your jar finish to the right closure type, lining, and size. Whether you're a small supplement brand launching your first SKU or an established manufacturer running tens of thousands of units a month, we have a closure program built for your scale.
