California Agricultural Associations and Commodity Boards: Who They Are and What They Do

California fields more than 400 distinct commodity and industry organizations — a figure that surprises even longtime observers of the state's farm economy. These bodies range from small grower cooperatives to state-chartered marketing boards with statutory assessment authority, and together they shape pricing, research funding, lobbying strategy, and export promotion across the state's broad agricultural landscape. Understanding the difference between a voluntary trade association and a mandated commodity board matters enormously for any producer deciding where to send dues — or trying to figure out why a check is being withheld before the crop ships.

Definition and scope

Agricultural associations and commodity boards occupy two distinct legal categories, though from the outside they can look nearly identical — both hold annual conferences, publish newsletters, and hire Sacramento lobbyists.

A voluntary agricultural association is a membership organization formed under California Corporations Code or federal nonprofit law. The California Farm Bureau Federation, for instance, operates as a voluntary membership body representing farm and ranch operators across 53 county Farm Bureaus. Membership is elected; dues are paid by choice. The organization's authority derives entirely from its members' willingness to participate.

A commodity marketing board or commission, by contrast, is a creature of state statute. California's Agricultural Code authorizes the California Department of Food and Agriculture (CDFA) to establish marketing orders and commodity commissions under programs such as the California Marketing Act of 1937 (California Food and Agricultural Code §58701 et seq.). When a marketing order is active, every producer of the covered commodity within California is subject to mandatory assessments — regardless of whether they voted for the order or belong to any association. The California Avocado Commission, the California Walnut Board, and the Strawberry Commission all operate under this framework.

Scope and coverage: This page addresses organizations operating under California state law and CDFA authority. Federal marketing orders administered by the U.S. Department of Agriculture — such as the federal milk marketing orders that set minimum prices for fluid milk — fall outside the scope of state commodity board governance, though California producers may be subject to both simultaneously. Producers operating exclusively in interstate commerce under USDA authority, or multistate commodity programs headquartered outside California, are not covered here.

How it works

State commodity commissions follow a structured lifecycle:

1. Petition phase — A majority of producers (by volume or number, depending on the commodity) petition CDFA to establish a marketing program.
2. Public hearing — CDFA holds a formal proceeding where producers, handlers, and the public may testify. The record determines whether a program is economically justified.
3. Producer referendum — Eligible producers vote; approval thresholds vary by statute but typically require support from producers representing a majority of production volume.
4. Assessment collection — Once established, assessments are deducted at the handler level — the packer, processor, or first purchaser — before payment reaches the grower. This is why producers sometimes receive less than the posted commodity price without any deduction appearing on an invoice.
5. Program activities — Collected funds are directed by a board of directors (appointed or elected from the producer community) toward research, pest and disease management, domestic promotion, and export market development.

The California Dried Plum Board, for example, directs assessment revenue toward both domestic health-messaging campaigns and international trade missions, particularly in markets across East Asia, under authority delegated by CDFA. The California Milk Advisory Board operates similarly, funding the longstanding "Real California Milk" campaign from mandatory assessments on California dairy producers — a program overseen through the California Department of Food and Agriculture's Dairy Program.

Voluntary associations work differently. The California Farm Bureau collects dues, sets policy positions through delegate assemblies, and engages the legislature — but it cannot compel a producer to join or deduct fees from a sale.

Common scenarios

A walnut grower discovers an unfamiliar deduction. Handlers remitting to the California Walnut Board deduct assessments before issuing payment. Growers who haven't encountered this before sometimes interpret the deduction as an error. The deduction is statutory, not discretionary.

A new specialty crop considers organizing. A coalition of California-grown quinoa producers wanting to fund joint research could pursue either a voluntary checkoff-style association or petition CDFA for a formal marketing order. The marketing order route creates binding participation — including for competitors who might otherwise free-ride on research funded by early adopters.

A producer challenges an assessment. Producers subject to mandatory assessments have due process rights established in Glickman v. Wileman Brothers & Elliott, Inc., 521 U.S. 457 (1997), though the Supreme Court upheld the constitutionality of mandatory assessments for generic advertising in that case. Subsequent litigation — particularly Johanns v. Livestock Marketing Association, 544 U.S. 550 (2005) — established that assessments funding government speech do not violate the First Amendment.

Decision boundaries

The practical question for most producers is whether a given organization can compel participation — and the answer depends entirely on whether a marketing order exists for that commodity in California.

Producers marketing a commodity covered by an active California marketing order should expect assessment deductions as a structural feature of the market — equivalent, in operational terms, to a property tax on the act of selling. Those operating in commodity categories without a marketing order, such as most small-scale specialty crops, interact only with voluntary organizations and retain full discretion over membership.

The California Agriculture Regulations framework that governs both types of entities ultimately traces back through CDFA, making that agency the single most important reference point for producers trying to understand their obligations.
