In 2024, Washington approved HB 1551 (codified as 70A.565 RCW) to restrict lead in cookware and subsequently issued a guideline to assist cookware manufacturers and sellers in complying with the new law.

On May 13, 2025, the governor of Washington signed Engrossed Substitute SB 5628 (Chapter 266, 2025) into law to revise the state’s law on lead in cookware.
