WA SB5816

Adds "juice grapes" (grapes intended for nonfermented juice products) to the list of agricultural products covered under Washington's agricultural contract negotiation law (RCW 15.83)

Juice grape producers gain access to the state's collective bargaining process, allowing accredited producer associations to negotiate prices and contract terms with handlers and processors

Negotiations for juice grapes must begin at least 60 days before normal harvest date and conclude within 30 days of that date, matching the existing timeline for pears

Amends the definition of "agricultural products" in the statute to include juice grapes alongside pears, sweet corn, and potatoes
