No course of conduct or any performance, usage of the trade or delay or failure of NAI in exercising any rights hereunder shall affect or waive any rights of NAI.3. ORDERS
Orders will be initiated by Customer issuing a purchase order (“order”) to NAI. Purchase Orders will identify the Products, unit quantities, part numbers, descriptions, applicable prices and requested delivery dates. Orders are subject to NAI’s acceptance and to these Terms and Conditions. Customer may, without charge, cancel an order for standard Products provided such order is scheduled for shipment by NAI more than sixty (60) days after NAI receives written notice of cancellation from Customer. Customer requests to cancel an order for standard Products scheduled for shipment by NAI within sixty (60) days after NAI receives written notice of cancellation may be accepted by NAI in its sole discretion, which acceptance may be subject to Customer’s accepting a charge determined in writing by NAI. Customer requests to reschedule are subject to acceptance by NAI in its sole discretion. Orders may not be canceled or rescheduled after delivery by NAI to the carrier. Customer may not cancel orders for non-standard or custom Products. Product specifications and availability are subject to change without prior notice. NAI reserves the right to limit quantities.


Orders are billed at the prices in US dollars in effect at the time of placement of an order. The website reflects the latest pricing information available at the time of printing. Prices shown in the catalog are subject to change without notice. If Customer does not purchase the quantity upon which quantity prices are based, Customer will pay the non-discounted price for the quantity actually purchased and/or a cancellation or restocking fee. Prices for any rescheduled deliveries may be increased by NAI in the event of an increase in NAI’s prices or costs or causes beyond NAI’s reasonable control.

Payment shall be made at the time of purchase or on net thirty (30) day terms from date of invoice with NAI approval. Customer will submit such financial information as NAI may reasonably require for determination of credit terms. Checks are accepted subject to collection and the date of collection will be deemed the date of payment. Any check received from Customer may be applied by NAI against any obligation owing by Customer to NAI under this or any other contract, regardless of any statement appearing on or referring to such check, without discharging Customer’s liability for any additional amounts owing by Customer to NAI. The acceptance by NAI of such check will not constitute a waiver of NAI’s right to pursue the collection of any remaining balance.Customer will pay the entire net amount of each invoice from NAI pursuant to the terms of such invoice without offset or deduction. Invoices not paid when due will bear interest to date of payment at the annual rate of eighteen (18%) percent or such lower rate as may be the maximum permitted by law. If Customer fails to make payment when due, NAI may pursue any legal or equitable remedies, in which event NAI will be entitled to reimbursement for costs of collection and reasonable attorneys’ fees. There is a $25.00 service charge on all returned checks.

NAI is required by law to collect sales tax in New York and Massachusetts. This tax is in addition to the purchase price of the Products subject to an order. Customers claiming exemption from tax must sent NAI an original signed tax exemption certificate.Absent a valid signed tax exemption certificate on file at NAI, all applicable taxes will be charged to the Customer.

NAI will make reasonable efforts to initiate shipment and schedule delivery as close as possible to Customer’s requested delivery date(s). Customer acknowledges that delivery dates provided by NAI are estimates only and that NAI will not be liable for failure to deliver on such dates. Selection of the carrier and delivery route will be made by NAI unless specifically designated by Customer.

Unless other terms are expressly agreed and contained on the shipping documentation, shipments by NAI to U.S. locations are made DAP address specified by Customer (Incoterms®2010); shipments by NAI to locations outside the U.S. are DAT terminal specified by Customer (Incoterms®2010). Risk of loss will pass to Customer upon delivery, but title shall remain in NAI until payment in full for the Products by Customer. Products invoiced and held by NAI at Customer’s request will be held at Customer’s risk and expense. Delivery of any installment of Products within thirty (30) days after the date requested will constitute a timely delivery. Thereafter, delivery will be timely unless prior to shipment NAI has received written notice of cancellation valid under Section 3 of these Terms and Conditions. Delay in delivery of one installment will not entitle Customer to cancel any other installment(s).
