Terms and Conditions

Prices and Terms

All prices in INW Price Lists and forms are shown in U.S. dollars, unless specifically stated otherwise, FOB INW’s shipping point.  Prices, specifications, and policy statements are current at time of printing and are subject to change without notice.

Order Placement

To place an order, or if you have questions about INW products, ordering, or shipping information, call one of our customer service representatives at 800-776-9355.

For orders exceeding $1000, we require a written or faxed copy of the Purchase Order or confirming document, complete with authorizing signature.

Terms of Payment

Payment may be through established credit, or by VISA® or Mastercard® charge cards.  Customers are normally invoiced on the date of shipment. Payment is due within 30 days of invoicing.  Late payments are subject to the maximum interest charges allowed by law.

Sales and Use Tax

INW is required to collect sales and use taxes as appropriate by local taxing authorities.  If orders from your organization are tax-exempt, please provide the appropriate documentation at the time of the order.

Quantity Discounts

In some cases discounts are available.  Talk to your sales representative for more information.


For items that are cancelable and have been shipped, the customer must return the order or notify INW within 10 days or it will be considered accepted.  Additionally, INW charges a restocking charge of 15%.  Shipping charges are the responsibility of the customer.

INW will quote items that are non-cancelable.  For items that are non-cancelable, once work has commenced on the item cancellations will not be accepted.

Shipping and Transportation

INW’s Shipping Departments will select the best method of shipment, and will accommodate rush shipments by air at an additional charge when regulations permit.  Hazardous materials are shipped according to applicable transportation regulations.  INW reserves the right to approve carriers, modes, and rate of transportation.  Delivery is complete when INW places the shipment with the first carrier, and risks of loss or damage in transit are the responsibility of the buyer.

Tracking and Claims

Should your purchase not reach its destination, INW will assist you in tracking the shipment.  If your freight appears to be damaged when you receive it, do not accept it from the carrier.  If you have completed acceptance and discover hidden damage, contact the carrier for assistance with filing a claim.

Returning Merchandise

Normal business transactions inevitably require an occasional return of merchandise for exchange, credit, repair, or warranty replacement.  No material may be returned without INW’s express consent and proper documentation. All shipments to INW must be labeled with an RMA number (provided by INW) or the shipment will be returned to the sender.
