Who makes Kirkland Signature Macadamia Clusters, Salted Caramel & Milk Chocolate, 32 oz?
No reliable public evidence identifies the manufacturer of Kirkland Signature Macadamia Clusters, Salted Caramel & Milk Chocolate, 32 oz as of July 6, 2026.
The common claim
What most answers say — and what the evidence supports
Popular answers split between Blommer Chocolate Company (citing Costco's 2013 Costco Connection cocoa feature) and Hawaiian macadamia brands such as Mauna Loa or Hawaiian Host (by association with the nut). Neither is documented as the maker. The Costco Connection supports only that Blommer supplies the chocolate for the Kirkland chocolate program, after which Costco ships it to separate, unnamed candy suppliers who add the nuts and mold the pieces. The current 32 oz salted-caramel-and-milk-chocolate clusters are labeled a Product of the USA - not Hawaii - and no on-package co-brand, recall notice, or Costco listing names the finished-goods maker.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below is the documented search — every database and record we checked, and what each one returned.
Recall sweep (FDA openFDA food-enforcement API; CPSC SaferProducts.gov REST API) for Kirkland + macadamia July 6, 2026
No recall on file for Kirkland Signature macadamia clusters (openFDA 'kirkland' AND 'macadamia' returns NOT_FOUND; CPSC 'macadamia' empty). The recall route surfaced no co-packer for the finished product.
Costco.com PDP manufacturer field (mfName route; costco.com blocks bots, Wayback only) July 6, 2026
No existing Wayback snapshot for the Kirkland Signature Macadamia Clusters PDP (item 100083149) on either costco.com /p/ or costcobusinessdelivery.com - all CDX queries returned zero 200-status captures. Because costco.com blocks automated fetch, a fresh snapshot cannot be created here; capturing the live PDP's mfName is a browser follow-up for Ian. The mfName route did not resolve the finished-goods maker.
Costco's own publication - The Costco Connection, October 2013 cocoa feature ('Chocolate designed the Costco way'), via Wayback; corroborated by Daily Meal (2023-08-03) July 6, 2026
Costco's own magazine names the chocolate supplier but not the finished-goods maker: it describes "their Kirkland Signature chocolate supplier, U.S.-based Blommer Chocolate Company," which roasts the beans and converts them into chocolate, after which "the chocolate is then shipped to Costco's candy suppliers, who blend in various ingredients called inclusions, such as nuts, fruit or unique flavorings, and mold the mixtures." So Blommer supplies the chocolate; a separate, unnamed candy supplier adds the macadamias and caramel and molds the finished clusters. Daily Meal (2023) echoes that Blommer's chocolate goes into Kirkland's "chips, dipped fruit, and nuts" without naming the candy maker.

On-package co-brand / label review (Costcuisine review of the macadamia clusters) July 6, 2026
The photographed-label review shows the product labeled a 'Product of USA' and names no manufacturer, distributor, or co-brand (no Mauna Loa, Hawaiian Host, or Blommer mark). The package identifies no finished-goods maker.
Hawaiian macadamia-brand route (Mauna Loa / Hawaiian Host) July 6, 2026
Mauna Loa and Hawaiian Host (now the same company group) circulate as guesses because macadamias are associated with Hawaii, and Costco has separately sold a 'Kirkland Signature Hawaiian Chocolate Toffee Coated Macadamia Nut Clusters' variant. But no source documents either brand as the maker of the Kirkland clusters, and the current 32 oz salted-caramel-and-milk-chocolate product is labeled a Product of the USA, not Hawaii. The Hawaiian-brand route did not confirm a maker.
Community / listicle scan (Costcuisine, Chowhound, Food Republic, Daily Meal) and ImportYeti / US customs July 6, 2026
Listicles repeat the Blommer claim, collapsing Blommer's documented chocolate-supply role into finished-goods manufacturing; none names the candy supplier that assembles and packages the clusters. ImportYeti surfaced no Costco macadamia-cluster supplier signal, and the route is structurally weak regardless (domestic confectionery production plus freight-forwarder masking, tier 5 caveat). No consistent finished-goods maker emerges.
