Shipping Information

Why can't I see the freight cost for my order?

Freight charges are extremely complicated as the freight rates are based upon the weight of the shipment, density of the goods, ease of handling, damage rate versus cost of the goods, distance traveled and the volume of freight handled between origin and destination for the Freight Company as well as services required at the origin and destination. In other words there is no "one size fits all" for freight pricing. Massco Industries, LLC provides freight and shipping estimates as a courtesy to our customers.

These estimates are based on information given to us at the time of inquiry, and are subject to change due to fuel surcharge, address change, redirected shipments, residential or refused shipments. We take pride in offering the absolute lowest rate possible and apologize for the inconvenience.

What are my freight options?

1)   Ship your order using your freight carrier and account number and the trucking company will bill you directly.

2)   When requesting your quote, ensure you provide your shipping destination in the respective text-field. We can then calculate and include the corresponding freight charge directly into your quote for your review
