processing (Robinson-Patman Act § 2(e))

the conversion of dextrose into candy would seem to conform to the current understanding that processing is a mode of treatment of materials to be transformed or reduced to a different state or thing. In view of the purpose of the statute to prevent the enumerated discriminations attending the sale of a commodity for resale, the precise nature or extent of the processing before resale would seem to be immaterial. The statute is aimed at discrimination by supplying facilities or services to a purchaser not accorded to others, in all cases where the commodity is to be resold, whether in its original form or in a processed product.
