The NWFA offers two industry-accepted standards for the manufacturing of wood floors; NOFMA Certified Flooring and Responsible Procurement Program (RPP) flooring. As a manufacturer, these standards verify you are producing quality flooring that adheres to a set of industry-specific guidelines.


For more than 100 years, NOFMA certification has provided a mark of distinction for wood flooring. NWFA’s NOFMA certification provides an assurance that wood flooring meets or exceeds industry standards for grade, configuration, moisture content, and average board length. Certified mills are inspected a minimum of twice per year to ensure grading standards are consistently met.

The Responsible Procurement Program (RPP) is a joint initiative between leading environmental groups and industry manufacturers committed to producing and promoting wood floors that come only from environmentally and socially responsible sources, improving forest sustainability for future generations.

To accomplish this, the RPP has been designed to:

  • Enable participating companies to exercise environmental responsibility in their sourcing, encompassing all wood products that they procure
  • Help companies transition over time to products certified to the standards of the Forest Stewardship Council (FSC)
  • Provide options for exercising due care under the U.S. Lacey Act
  • Provide participants with effective marketing support including use of a program logo

The RPP was developed by the NWFA in conjunction with SCS Global Services, Forest Stewardship Council U.S (FSC), and the World Wildlife Fund.

Members of the RPP program, commit to continuous progress within the RPP framework, as measured by increased sales of products approved by the program. The RPP provides progressive “tiers” that act like rungs on a ladder on which participants move gradually upward toward ever-higher levels of social and environmental performance.

The RPP is also part of the ICC 700 National Green Building Standards (NGBS). Certification to this green building standard provides a credible pathway for the design and construction of sustainable residential buildings, with the goal of minimizing their environmental footprint. NGBS is the only residential green building rating system approved by ANSI as an American National Standard. 

Congratulations to the following companies that are certified under the RPP:

  • AHF
  • Anderson Hardwood Floors
  • Mullican Flooring
  • Shaw Hardwoods
  • Sheoga Hardwood Flooring & Paneling
