The American Wood Protection Association (AWPA) is a non-profit organization which promulgates voluntary wood preservation standards.

AWPA Standards are developed by its technical committees in an ANSI accredited consensus-based process that involves individuals from all facets of wood preservation: Producers of preservatives and preservative components; producers of treated and untreated wood products; end users of treated wood; engineers, architects and building code officials; government entities, academia, and other groups with a general interest in wood preservation.

AWPA’s Standards are universally specified for wood preservation in the USA, and are recognized worldwide.
