Terms and Conditions of Sale: United States

Absolute minimum order: $40.00. This includes all products, including ACCU DYNE TEST™ Marker Pens and surface tension test fluids.

Shipping and Handling: Please note: we strive to pack orders cost-effectively, and offer active discounts from published rates, especially for air shipments. Orders can be placed as pro forma requests if you need an exact quote in advance.

Our default shipping method is via UPS ground service, prepaid and allowed. We can also ship most products via UPS or FedEx air, prepaid and added to your invoice. If you prefer, we can ship via UPS air or ground collect, or FedEx air collect. All shipments are FOB Claremont, NH.

Payment terms: Within 45 days by U.S. check for approved accounts; or payment by MasterCard, Visa, or American Express at time of sale. Payment by check will trigger an automatic 3% discount on the entire product total, which will show as a separate line item at the bottom of the invoice. Repeated - or egregiously - late payments will result in the loss of this discount.

Backorders: If any product is backordered we will contact you for instructions on your shipping preferences.

Returns and Restocking Charges: Viscosity cups and ACCU DYNE TEST™ products are NOT returnable. All other catalog items can be returned, as long as they are unused and in resellable condition, but for some products there may be a significant restocking charge. In all cases, returns must be approved in advance, and clearly identified with an assigned Return Authorization Number. If returnability is a concern, be sure to inquire in advance.
