Supplier Resources


A Commitment to Continuous Improvement is our ultimate goal by helping our customers eliminate the need to inspect incoming product and providing a product which meets and exceeds their quality requirements. We look for long term relationships or partnerships with suppliers. With the first order you are a partner and EVCO Plastics is only as good as our partners.

See our Supplier Excellence Manuafor further information.


The supplier is to recognize that the Buyer is the only authorized Purchasing Agent of the Company and therefore is the only person within the Company that can commit Company resources or authorize changes that may affect costs, delivery or warranty of an order. Communications and interviews are to be conducted between suppliers and authorized purchasing agents. Any communication with other EVCO Plastics personnel must be conducted with the knowledge and approval of purchasing. All suppliers for contracted services are required to advise the Buyer of estimate prior to commencing work and also in case of price fluctuations.


Every supplier is required to obtain a purchase order number from the Buyer. This number must appear on the packing list, invoice, acknowledgments and on skid or pallet identification accompanying the materials. On this purchase order will be listed an EVCO “item number” for each product purchased. In order for our receiving department to efficiently account for incoming items, it is important that this number accompany the same documents as listed above.

All invoices, for all locations, are mailed to:

EVCO Plastics
P.O. Box 497
DeForest, WI 53532


Send original quotes to the purchasing agent with a copy to the requisitioner if other than purchasing. EVCO Plastics conducts ongoing cost management, we do not abandon the search for qualified vendors once we have established an approved supplier.


Any sample or product to be received at EVCO Plastics at no charge is to be coordinated through the purchasing department. If payment is expected, obtaining a purchase order is absolutely essential.


Since we are a manufacturer, most of the material purchased is exempt from sales and use tax. Exemption certificates will be sent only when requested by the supplier.


Hours are 8:30 A.M. to 4:00 P.M. Monday through Friday. Making an appointment is necessary to ensure no time is lost on your part or ours.


EVCO Plastics maintains Material Safety Data Sheets (MSDS) on all necessary products. All purchased materials used in part manufacture shall satisfy current governmental and safety requirements for restricted, toxic and hazardous materials; as well as environmental, electrical and electromagnetic requirements and standards applicable to the country of manufacture and sale.


EVCO Plastics realizes the importance of our suppliers, therefore, personal gifts are not necessary nor are any further expressions of appreciation.


To eliminate any additional expenses or inconveniences, any alteration to the original contract should be acknowledged by purchasing prior to receipt. It is our policy that receiving can refuse shipments that have not been issued a purchase order. Unconfirmed early releases could result in a refused shipment.
