41 - Commerce de gros

"This sector comprises establishments primarily engaged in wholesaling merchandise, generally without transformation, and rendering services incidental to the sale of merchandise. 

The wholesaling process is an intermediate step in the distribution of goods. Many wholesalers are organized to sell merchandise in large quantities to retailers, and business and institutional clients. However, some wholesalers, in particular, those that supply non-consumer capital goods, sell merchandise in single units to final users. 

Sales of capital goods or durable non-consumer goods used in the production of goods and services, such as farm machinery and equipment, heavy-duty trucks, and industrial machinery, are always included in wholesale trade."
