Roundup Concentrate Settlement: $21.5 Million Refund Deal Over "Makes Up To" Gallon Claims

Monsanto sold Roundup herbicide in ready-to-use and concentrate forms, and marketed the concentrates as a better value. According to the Eighth Circuit's opinion, the plaintiffs alleged that Monsanto misled buyers about how much spray solution the concentrates made; in one example cited by the court, a label advertised that the product could make up to ten gallons, but when diluted according to the package instructions it made just over five. The plaintiffs claimed this misrepresented the products' value by nearly 50 percent on some units.

Class counsel first sued in the Central District of California, where the court certified only a California class. They then filed Rawa v. Monsanto Company, No. 4:17-cv-01252, in the Eastern District of Missouri for buyers in the other 49 states, and the California case was transferred there so both could settle together. Monsanto denied the allegations and any wrongdoing, and the settlement is not a finding that the labels were false.

The settlement also released The Scotts Company, which marketed Roundup consumer products, from the labeling claims. Roundup's active ingredient, glyphosate, is the subject of separate litigation over cancer risk.

The court certified a settlement class of all persons in the United States who, during the class period, bought Roundup Weed & Grass Killer Concentrate Plus or Roundup Weed & Grass Killer Super Concentrate in the U.S.:

• for personal or household use, not for resale, distribution, or commercial use;
• in packaging whose neck or shoulder label said the product "makes up to" a certain number of gallons; and
• without having already received a full refund.

For California buyers the class period started October 13, 2012; in other states it began on a date set by each state's statute of limitations. The settlement website noted the "makes up to" statement was removed from the neck or shoulder of Concentrate Plus bottles around late 2014 but not from Super Concentrate. Other Roundup products, including ready-to-use sprays, were not covered.

Refunds were set at about 50% of each product's weighted average retail price, capped at 20 units per household:

Product	Avg. retail price	Refund
Super Concentrate 35.2 oz.	$42.48	$21
Super Concentrate 53.7 oz.	$62.88	$31
Super Concentrate 64 oz.	$72.64	$36
Super Concentrate 128 oz.	$105.85	$53
Concentrate Plus 32 oz.	$21.31	$11
Concentrate Plus 36.8 oz.	$22.97	$11.50
Concentrate Plus 40 oz.	$26.40	$13
Concentrate Plus 64 oz.	$44.54	$22

According to the Eighth Circuit, the administrator validated 70,360 claims worth $10,732,832, a claims rate of about 13% of the $164 million in covered retail sales. The district court awarded attorneys' fees of 28% of the fund. Because valid claims fit within the fund, the settlement called for leftover money to go to court-approved cy pres organizations rather than back to Monsanto. See our guide to what happens to unclaimed settlement money.

Claims were filed online or by mail through the settlement administrator, Dahl Administration. The claim form asked for contact information and either proof of purchase or a sworn statement under penalty of perjury describing the purchases. A receipt was not required, but claims without one relied on a signed affirmation.

This is a common setup in low-dollar consumer settlements; see our guide on settlements that do not require proof of purchase. Claiming more units than you bought is fraud, and administrators screen for it.

Event	Date
Preliminary approval	December 6, 2017
Claim and opt-out deadline	March 6, 2018
Objection deadline	March 27, 2018
Final approval hearing	April 17, 2018
Final approval order	May 25, 2018
Appeal filed	June 14, 2018
Eighth Circuit affirms	August 20, 2019

An objector, James Migliaccio, appealed on the ground that combining the California class with the nationwide class hurt California buyers. The Eighth Circuit rejected every argument and affirmed on August 20, 2019, finding the settlement reasonable, fair, and adequate. The appeal delayed payments by more than a year. As of September 2026 the settlement website is offline, and we could not confirm the exact date checks were mailed from the official site.

If you did not file by March 6, 2018, you cannot recover under this settlement, and unless you opted out, you released labeling claims about these products for the class period. Newer purchases outside the class period are not covered by this release, but we are not aware of an open labeling class action over Roundup Concentrate as of September 2026.

The release did not cover personal injury. People diagnosed with non-Hodgkin lymphoma after using Roundup have separate claims tracked on our Roundup cancer lawsuit page. If that applies to you or a family member, a free case review can connect you with independent attorneys who handle those cases. For consumer claims open now, see our open settlements list.
