These are estimates, not guarantees. We do not warehouse equipment ourselves — your order is placed with the manufacturer once you buy, and most items are released for shipment within 1 to 3 business days. If your item is on back-order, or the manufacturer confirms a longer lead time, we will contact you promptly and you may cancel for a full refund with no fee.

Standard shipping (free on every order) is curbside or dock-to-dock delivery to a commercial address in the 48 contiguous states and DC, or parcel delivery for smaller items. We are not currently set up to ship to Alaska, Hawaii, Puerto Rico or other US territories. Liftgate, residential, limited-access and inside delivery, rigging and crating are not included — typically $150 to several hundred dollars, quoted in writing and charged only with your prior approval.

Freight deliveries require a scheduled appointment and someone must be present to sign. Need a firm date before you buy? Call (720) 575-1376 or email support@techforgedirect.com with the model number.

Free standard shipping on every order to the 48 contiguous states and DC. No minimum order and no shipping charge at checkout.

30 days to request a return from the date you receive your order. Email support@techforgedirect.com with your order number and reason. We will assess your request and, once approved, send you an RMA number and detailed instructions. Do not ship anything back before you have an RMA number.

1. Return shipping costs

You as the customer are responsible for paying the return shipping costs of the items in your order. On freight-shipped machinery this can be substantial — we quote the exact amount in writing before you commit, so you decide with the full figure in front of you.

2. Preparing your return

Parcel-sized items: we email you a return label, and its cost is deducted from your refund. Freight items are collected under a bill of lading we arrange. The item must be unopened, unused and in delivery condition, including all original packaging and accessories, in a condition such that it can be re-sold as new. Machinery must not have been wired in or powered on. Photographic evidence is required.

3. Restocking fee

Change-of-mind returns carry a 25% restocking fee, deducted from your refund. On a $10,000 machine that is $2,500.

4. Damaged or incorrect products

Note it immediately when signing for delivery and send photographs to support@techforgedirect.com the day of delivery. We will ensure you get the correct product you ordered, undamaged, as soon as possible, at no cost to you — no return shipping charge and no restocking fee.

5. Refunds

Processed within 7 business days of your returned item being received and inspected.

6. Cancellations

Cancel any time before your order ships for a full refund with no fee.
