Lab Samples & Contract

As customers begin the Custom Formulation process with RainShadow Labs we will enlist the lab to create customized product samples for you to test. These will represent different versions of what our lab has understood to be requested for the particular product in question. The lab order form will be entered into the lab formulation line up and usually in 7-10 business days your first round of samples will ship out to you. There is an initial lab fee involved in this process to cover lab time and the first domestic shipment. You will be billed $130.00 per hour for the Customized Sample Process.  This initial lab fee covers all lab revisions and adjustments to your samples until you sign off on the formulations being worked on and the first domestic shipment.  Freight will be billed separately for all additional samples adjustments requested or for international shipments. Generally the lab time involved is somewhere between one to three hours. Please understand that the fee is an initial lab fee and after the first fee is billed to your company you will not be charged again to finalize your product.  If reformulating and finalizing custom formulations takes us beyond six months, then a new lab fee will be initiated which will cover the next six months of lab time. The lab fee covers the first freight charges for ground shipment; freights charges after this first round will be incurred by the customer. Custom formulation is limited to 4 products at a given time. Additional formulations can be initiated upon completion of active lab samples.

RainShadow Labs will own the formulations that are created in our lab and RSL will sign a Nondisclosure/Non compete legal document to ensure that we are only making your product for your company. We will never share your formulation or ingredient information with any company other than yours.  

In order to begin this process please choose from one of the following forms, fill it out, and submit it to RSL.  We will follow up with an immediate response. You can email these to; fax them to 503-366-3400; or mail them in with 1-2oz of your sample product (Form A) to 300 Port Ave, St Helens, OR 97051.
