Abstract: A flame-retardant polyamide molding compound may have low phosphorus content. Such a polyamide molding compound may include (A) a polyamide matrix including polyamide(s) having at least 8 carbon atoms per amide unit; (B) a flame retardant composition comprising (B1) metal-free aryl phosphate(s), (B2) aryl phosphonate(s), (B3) carbohydrate polyol(s), (B4) melamine cyanurate(s), and (B5) optionally, non-phosphorus-comprising flame retardant(s). A total phosphorus content from the flame retardant composition may be in a range of from 0.5 to 1.5 wt. %, based on total polyamide molding compound weight
