Direct answer
Commodity is a defined term in the International Fire Code (IFC) 2009, in High-piled Combustible Storage. The code's own words are: “A combination of products, packing materials and containers.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 8 chapters of this corpus, most often in High-piled Combustible Storage (IFC 2009), Soils and Foundations (IBC 2009), Wood (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.
