de-activating the tabs css from jquery-ui.css - css

Question

I am using Jquery UI, and I need the jquery-ui.css for datepicker and buttonset. However, I am also using jquery tabs in the site.
I have added custom styling to the tabs in my own css folder (not jquery-ui.css), but when I add the jquery-ui.css it adds lots of other styling to my tabs, which look really bad.
I was wondering is there a way to remove the tabs styling from jquery-ui.css?
If it helps this is the html and styling for my tabs:
<ul id="product_tabs_list"><li>Description</li><li>Features</li><li>Specifications</li><li>Technical</li><div class="clr"></div></ul>
#product_tabs_list{
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
margin-bottom: 10px;
padding: 11px 5px;
text-align: center;
}
#product_tabs_list li {
float: left;
}
#product_tabs_list li a {
background: #fff;
background: -webkit-gradient(linear, 0 0, 0 bottom, from(#fff), to(#eaeaea)) no-repeat;
background: -webkit-linear-gradient(#fff, #eaeaea) no-repeat;
background: -moz-linear-gradient(#fff, #eaeaea) no-repeat;
background: -ms-linear-gradient(#fff, #eaeaea) no-repeat;
background: -o-linear-gradient(#fff, #eaeaea) no-repeat;
background: linear-gradient(#fff, #eaeaea) no-repeat;
border: 1px solid #cfcfcf;
color: #3463a0;
font-weight: bold;
padding: 10px 20px;
-webkit-text-shadow: 1px 1px 1px #fff;
-moz-text-shadow: 1px 1px 1px #fff;
text-shadow: 0px 1px 1px #fff;
}
#product_tabs_list li a:hover {
background: #fff;
}
#product_tabs_list li.ui-tabs-active a {
background: #3463a0;
background: -webkit-gradient(linear, 0 0, 0 bottom, from(#3463a0), to(#233f64)) no-repeat;
background: -webkit-linear-gradient(#3463a0, #233f64) no-repeat;
background: -moz-linear-gradient(#3463a0, #233f64) no-repeat;
background: -ms-linear-gradient(#3463a0, #233f64) no-repeat;
background: -o-linear-gradient(#3463a0, #233f64) no-repeat;
background: linear-gradient(#3463a0, #233f64) no-repeat;
color: #fff;
-webkit-text-shadow: 1px 1px 1px #00204b;
-moz-text-shadow: 1px 1px 1px #00204b;
text-shadow: 0px 1px 1px #00204b;
