New Order Acknowledgement

Once a new purchase order is received, Yankee Environmental Systems will fax an order acknowledgement with an estimated ship date. If you require a quote, the quote will include an estimated delivery date which is always calculated as "After Receipt of Order (ARO)" the ship date is only an estimate. Orders are typically paid in full at the time of the order by credit card, wire transfer or a US bank check mailed to Yankee Environmental Systems.

Prices quoted by Yankee Environmental Systems are Freight On Board (FOB) at the factory. All destination shipping costs, regardless of method, are the responsibility of the customer. Without exception, non-prepaid orders require the customer to insure freight shipments. Within the US, Yankee Environmental Systems will ship orders less than 150 lbs. via UPS. On orders exceeding 150 lbs., a US freight carrier such as ABF or Yellow will be used. Outside the US, the customer may request a specific carrier, in which case, all shipping charges will be applied to the customer's carrier account number. Note that your purchase order forms a binding contract that legally binds your organization to the terms listed here.

Shipping Damage

If you receive products that have been damaged in transit, it is important to keep the shipping carton, packing material, and parts intact. Please contact Yankee Environmental Systems for further instructions. All returns must have a valid RMA number written clearly on the outside of the box or the shipment will be refused.

Equipment Leasing

For US customers, we offer leasing on orders exceeding $100,000 (USD). Lease payments can provide for better cash flow compared to loan payments, particularly during the early years of equipment use. Lease payments can be tailored to match your cash flow needs even if your business is seasonal, permitting the matching of earnings generated by the use of the equipment. Upon expiration of a given lease, arrangements can be made for renewal, purchase, or return of the equipment; whichever fits your application. For more details contact your sales representative at at 413-863-0200.
