Your questions answered

When will my order ship?

Most orders ship within 24 hours of the order being placed, excluding weekends. If you haven’t gotten an update since placing your order after 48 hours, the product you ordered may be on backorder. Product stock information is always available on each product page. Some people do tend to miss this when ordering though. If a product is on backorder at the time of your order, it will be shipped to you the moment we have it back in stock.

Normally, yes! Our system automatically sends tracking information. If you do not receive tracking info, please let us know asap. Sometimes we need to update our system and we can always send you the tracking info manually.

The unfortunate truth is that sometimes we experience issues with our website and our shipping software communicating, so sometimes tracking will not be received. If you did not receive tracking and you would like it, just shoot us an email and I can send it over.

Yes, we do offer returns on purchases made within the past 60 days, but on ResoNix Sound Deadening Products only. If it is not a ResoNix sound deadening product, such as products from Helix, Accuton Automotive, Micro Precision, etc. we only offer store credit. The only thing we require for a return is that the product is not defiled in any way, and isn’t missing pieces. Meaning, if you order a box of 20 Mega CLD Squares, you must return the full box, or none of it will be returned. What we can do in some cases if something isn’t 100% is offer it for sale as b-stock to those in our ResoNix Customer Support Group on Facebook, but it will not be a traditional return. Just shoot us an email, fill out our contact form, or give us a call and we can help you out.

Returns have specific instructions, so please reach out for help with your return.

  1. You must reach out to us to inform us of the return. The best way to do this is by responding via email to your original order confirmation email.
  2. You must ship the product(s) back to.. ResoNix C/O Partnership, 50 Holt Drive, Building D3, Stony Point, NY, 10980
  3. You must also put “attn: Jenny, Order #XXXXX” (include your order number so we know which order it is to refund).
  4. Send tracking for the returns to [email protected]. Again, best to keep this emailed within the same chain as the order confirmation email. 
  5. Once we receive and inspect the products and determine they are in fact complete and undamaged, the return will be issued. Feel free to follow up with us throughout the process or if anything comes up. Thank you!
