STM Canna

Terms of Business

All STM systems carry a limited one-year warranty against defects in workmanship and/or materials.

Who is Covered:
Please note that results with STM Processing Equipment vary widely and depend on a myriad of factors, including but not limited to: correct grind size, age of material, quality of material, moisture content, strain, temperature, correct sized cone usage, quality of cones used, skill of the operator, and more. Our quoted weight ranges for flower, and trim are all general averages that have been reported to us by our customers, however your material may behave completely differently. We take no responsibility whatsoever for your results, only for the working functionality of our products. If you have any questions or concerns, please do not hesitate to talk to us about this very important disclaimer.

What Voids the Warranty:

  • Abuse, misuse, improper installation and modifications.
  • Custom applications.
  • No proof of purchase at the time of warranty. Claimant must provide proof of purchase, Warranty card, and a warranty authorization number (RMA) obtained from STM.
  • Finishes such as plating or painted surfaces with discoloration or rust due to inclement weather conditions, exposure to salt, exposure to chemicals, or lack of maintenance by the customer are not covered.
  • International grey-market product purchased through a dealer/distributor not authorized for your country will not be supported by this warranty.
  • Electrical parts are not covered under warranty.

Extent of Warranty:

Any STM system properly returned to STM will be repaired or replaced by STM. STM is not responsible for any other expense incurred by the customer under the terms of this limited warranty, nor is STM responsible for any damages either consequential, incidental, special, contingent or otherwise; or expenses or injury arising directly or indirectly from the use of the STM system purchased. Any system returned to STM must be sent at the customers expense along with the proof of purchase and warranty authorization (RMA). STM reserves the right to determine whether the terms of the warranty, set out above, have been properly followed. In the event that the terms are not followed this warranty is void.

STM is the sole determiner of abuse, misuse, installation errors and modifications – should any of these be found, this warranty is void. The duration of any and all implied warranties are limited to the duration of the express warranty. All incidental or consequential damages are herby excluded. The warranty gives you specific legal rights and you may have other rights, which vary from state to state. Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on how long an implied warranty lasts, so the above limitations and exclusions may not apply to you.

For International customers, please contact your client services representative regarding warranties.

All orders will be shipped COD (Cash on Delivery) unless other arrangements have been made. STM reserves the right to specify collection by certified check, money order, or company check. Personal checks are not accepted.


All orders are FOB Spokane, Washington. Orders received will fall in line and be serviced accordingly where the shipment date may be sooner than originally quoted. We will ship by the most reasonable means based on the volume of the order, unless otherwise specified.

Special Orders:

All special-order items must be paid in full before the order is placed. These items are non-returnable and no refund will be given. All special-order items will also take a longer period of time for the customer to receive, which will be quoted at the time of payment.


The purchaser of any parts releases the manufacturer of those parts and STM from all liabilities pertaining to use of the parts. The purchaser recognizes that any alteration or modifications to any STM system may increase the risk of accident and/or injury and may also render the machine inoperable.


No Refunds/Exchanges:  We do not accept returns or exchanges unless the item purchased is defective. All items that we ship are insured; if an item comes that is damaged from shipping, we will work closely with you to get you replacement parts as soon as possible. We may also request pictures or other identifying information to establish that damage was caused by the shipping carrier.

If you receive an item you believe is defective, please contact us with details of the product at (509) 204-3164 or email: [email protected]

We may ask you for pictures, video, descriptions, and other identifying information to make a determination. If you are unable to provide adequate documentation requested, your return request will be denied. If your item is deemed defective, which is solely at STM’s discretion, we will issue you an RMA # which you will need to place in and on the package. After receiving your RMA #, you may send the item to:

3223 North Market St.
Spokane, WA 99207

Upon receipt of the returned product, we will fully examine it and notify you via e-mail, within a reasonable period of time, whether you are entitled to replacement as a result of the defect. If you are entitled to a replacement, we will replace the product at no additional cost to you.


Since ownership of product transfers at the FOB point, claims for damaged, lost, or short shipments must be made at the time of receipt.
