The National Institute of Quality (Inacal) in Peru is advocating for the use of the Peruvian Technical Standard to set quality requirements for lemons. The goal is to enhance the quality of this citrus fruit and boost its sales in both local and international markets. The standard, which applies to all varieties of subtle lemon, specifies the physical characteristics the lemons should possess. Peru is renowned for producing two main lemon varieties: the subtle and the Tahitian, the latter being marketed overseas.
