Tri-Lateral Sales was founded in 1986 and was housed in North Kansas City. The original company sold packaging supplies. Due to customer demands we opened a branch in Springfield, Missouri in 1991. Expanded product lines and more growth caused a move to our current location in the Northland Business Park in Kansas City in 2000. Our Kansas City warehouse is 35,000 square feet while Springfield has 11,000 square feet. Both warehouses are utilized to accommodate our customer's. We have our own fleet of trucks to meet delivery needs. At Tri-Lateral Sales you will find whatever your company needs from packaging to janitorial to office supplies to industrial and shipping supplies. We pride ourselves in customer service, great products, and competitive pricing.
