Key part supplier: Not named by Costco Wholesale Not disclosed

Costco also owns Kirkland Signature; the other product-specific supplier records here do not establish one manufacturer or factory for all Kirkland goods. [1] [2]

Who owns Costco?

Costco’s 2025 annual report identifies the warehouse retailer and its Kirkland Signature private label. The retail company and the label are related but not interchangeable: identifying Costco as the brand owner does not identify a single manufacturer for every product bearing that label. [1]

Who actually makes Costco products?

Costco’s own food operations and independent, product-specific suppliers; KIK and Niagara are documented examples for particular products. [2] [3] [4]

The Morris manufacturing record documents Costco producing hot dogs itself. A dated KIK record identifies a specific Kirkland Ultra Shine dish liquid, while the Niagara record identifies particular Kirkland bottled sparkling water. These are separate product-level relationships, rather than evidence of one universal Costco contract factory. [2] [3] [4]

Where are Costco products made?

Morris, Illinois is documented for Costco hot-dog production. Other Kirkland factories vary by product; a complete global factory list is not public in the reviewed sources. [2] [3] [4]

Morris, Illinois is a named manufacturing location for the documented hot-dog operation. Supplier records for a dish liquid and bottled water should not be turned into a worldwide plant list without product-specific allocation. No factory country is inferred merely from a supplier’s office address. [2] [3] [4]

Is Costco made in China or the USA?

Costco’s US manufacturing example proves that some own-label goods are made through its own domestic operations. It does not establish US origin for all Kirkland goods or rule out imported products. The correct production answer depends on the particular product and the dated evidence attached to it. [1] [2]

Same factory, different label

Kirkland products share Costco’s label, but the documented suppliers differ across hot dogs, dish liquid and sparkling water. A supplier connection for one product does not establish the manufacturer of unrelated shampoo, batteries or golf equipment. Related guides below separate those product-specific evidence trails. [1] [2] [3] [4]

Where was your household bottle made?

A company address and a country of manufacture answer different questions. Start with your exact model.

  1. Check the package for a country-of-origin statement and lot number.
  2. Distinguish “distributed by” from an explicit manufacturer or origin statement.
  3. Contact the retailer with the exact product code and lot if the producer is not identified.
