title: UPS Rates query not matching final billed rate (Residential vs Commercial addresses)
body: <p>We've been battling the condition of having rates provided from the UPS API, being less than the final costs for shipping when we generate a transaction and final label.</p>
  <p>We were lead to believe that the cost difference was due to Residential vs Commercial address delivery. The problem with this is we do not see a means to specify if residential or commercial when we submit for final rates.</p>
  <p>We are able to tell if &quot;Residential Delivery = True or False&quot; from the address validation feature that suggests the best address. But in this case, we are only using this if the address is &quot;ambiguous&quot;.</p>
  <p>There is reference to similar issues in this <a href="https://stackoverflow.com/questions/22951358/ups-rates-api-gives-low-price">StackOverflow thread</a>. But the solution was more related to if the pickuptype is Counter or Daily Pickup.</p>
  <p>Does anyone have any experience in how to query if residential or commercial using the UPS API?  We can flag on our end which customer locations are residential or commercial, but we see nothing in the documentation offers a means to only get one rate or the other.</p>
