The Company manages its business under two operating segments, Material Handling and Distribution, consistent with the manner in which our Chief Operating Decision Maker evaluates performance and makes resource allocation decisions. None of the reportable segments include operating segments that have been aggregated. These segments contain individual business components that have been combined on the basis of common management, customers, products, production processes and other economic characteristics. The Company accounts for intersegment sales and transfers at cost plus a reasonable margin.

The Material Handling Segment manufactures a broad selection of durable plastic reusable containers that are used repeatedly during the course of their service life. At the end of their service life, these highly sustainable products can be recovered, recycled, and reprocessed into new products. The Material Handling Segment’s products include pallets, small parts bins, bulk shipping containers, storage and organization products, OEM parts, custom plastic products, consumer fuel containers and tanks for water, fuel and waste handling. Products in the Material Handling Segment are primarily injection molded, rotationally molded or blow molded. This segment conducts its primary operations in the United States and Canada. The Material Handling Segment serves a wide variety of markets, including industrial manufacturing, food processing, retail/wholesale products distribution, agriculture, automotive, recreational vehicles, marine vehicles, healthcare, appliance, bakery, electronics, textiles, consumer markets, among others. Products are sold both directly to end-users and through distributors. The acquisitions of Trilogy and Elkhart Plastics, described in Note 3, are included in the Material Handling Segment.

The Distribution Segment is engaged in the distribution of equipment, tools, and supplies used for tire servicing and automotive under-vehicle repair and the manufacture of tire repair and retreading products. The product line includes categories such as tire valves and accessories, tire changing and balancing equipment, lifts and alignment equipment, service equipment and tools, and tire repair/retread supplies. The Distribution Segment also manufactures and sells certain traffic marking products, including reflective highway marking tape. The Distribution Segment operates domestically through its sales offices and five regional distribution centers in the United States, and in certain foreign countries through export sales. In addition, the Distribution Segment operates directly in certain foreign markets, principally Central America, through foreign branch operations. Markets served include retail and truck tire dealers, commercial auto and truck fleets, truck stop operations, auto dealers, general service and repair centers, tire re-treaders, and government agencies. The acquisition of Tuffy, described in Note 3, is included in the Distribution Segment.

Total sales from foreign business units were approximately $48.0 million, $39.8 million, and $42.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. Export sales from the Company's U.S. operations were approximately $29.9 million, $17.7 million, and $23.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. Sales made to customers in Canada accounted for approximately 4.6%, 4.8% and 4.7% of total net sales in 2021, 2020 and 2019, respectively. There are no other individual foreign countries for which sales are material. Long-lived assets in foreign countries, primarily in Canada, consisted of property, plant and equipment, and were approximately $11.3 million and $11.8 million at December 31, 2021 and 2020, respectively.
