Who makes Kirkland Signature Bath Tissue, 2-Ply, 380 Sheets, 30 Rolls?

Zero recalls for 'bath tissue' or 'toilet paper'; 5 'Kirkland' recalls on file (prosecco bottles, cookware, mugs, non-Costco furniture), none tissue-related. The viral March 2020 Costco bath-tissue recall notice was a hoax (Snopes fact check, 2020-03-13; Costco confirmed no recall). No co-packer surfaced via the recall route.

Search for "Kirkland Signature" + "bath tissue" returned 0 opinions; no litigation naming a Kirkland bath tissue supplier found.

"Costco" and "Kirkland Signature" across all Clearwater Paper Corp filings (CIK 0001441236): 0 hits. "Costco" across Potlatch Corp filings (CIK 0001338749): 0 hits. No public filing by the most commonly rumored US private-label tissue maker ever names Costco or Kirkland.

About Kirkland Signature page (snapshot 2026-05-29) is marketing copy only; Wayback CDX sweep of customerservice.costco.com found no FAQ naming any Kirkland bath tissue supplier. Costco does not disclose the maker anywhere on its site.

Automated access blocked (HTTP 403); no Costco toilet-paper supplier signal surfaced via search snippets. Route is structurally weak here regardless: Costco masks many shipments via freight forwarders, and US-sold bath tissue is overwhelmingly produced domestically, so absence of import records proves nothing (tier 5 caveat).

No news article or executive statement directly names the maker of Kirkland Signature bath tissue. Closest evidence: Idaho Statesman / Moscow-Pullman Daily News (March 2020) documented Clearwater Paper's Lewiston, ID mill shipping 216,000 rolls of toilet paper to the Clarkston, WA Costco warehouse without ever naming the Kirkland brand (EastIdahoNews reprint archived: http://web.archive.org/web/20250818170414/https://www.eastidahonews.com/2020/03/idaho-has-a-giant-toilet-paper-factory-an-essential-business-amid-coronavirus-hoarding/). Clearwater later sold its entire tissue division to Sofidel America, completed 2024-11-01 (Business Wire release archived: http://web.archive.org/web/20250730062245/https://www.businesswire.com/news/home/20241031411494/en/Sofidel-Finalizes-the-Acquisition-of-the-Tissue-Division-of-Clearwater-Paper-Corporation-and-Becomes-the-Fourth-Largest-Tissue-Paper-Producer-in-North-America) — relevant only if Clearwater's unverified supply role existed. Not recorded in history[]: no source names the brand-manufacturer link, so this is an unverified supply event, not a documented prior manufacturer. Trade press confirms Kirkland bath tissue is Costco's best-selling product (~$500M/yr) but not who makes it.

Packaging carries an FSC Mix label, but the on-pack license code is not published online and an FSC label does not identify the producing mill. Route inconclusive. No other deterministic code registry (USDA EST/P-, FDA IMS, TTB, NDC, API EOLCS) covers tissue products.

Tier 6 claims are contradictory: Georgia-Pacific, Clearwater Paper (tissue business now Sofidel America), First Quality, Procter & Gamble, Kimberly-Clark, and Kruger are each named as the maker by different sources, all without evidence. The most specific claim - a retired tissue-industry professional quoted by OutKick (2025-05-20) saying Georgia-Pacific supplies 5 of Costco's 8 US regions and First Quality the other 3 - is itself unverified. No consistent single name emerges.
