Concerning the payment of turfgrass seed contracts.

Added new specific definitions for 'turf seed dealer,' 'turf seed producer,' and 'variety not stated seed' to clarify the parties and products involved.

Set a mandatory payment deadline of 30 days after seed delivery or May 1st of the following year, unless the contract explicitly states a later date before planting begins.

Required that any contract modification increasing payment terms must be paid for by the dealer upfront, equal to at least 25% of the contract value.

Added protections preventing contracts from forcing producers to waive their rights to sue in Washington state or agreeing to laws of another state.

Created a new enforcement process where the Department of Agriculture can investigate non-payment complaints and suspend a dealer's license if they fail to pay within 30 days of notice.

Removed the bill's previous application to general agricultural products and commission merchants, replacing it with a new chapter focused solely on turfgrass seed.
