You could customize the shipping module with something like:
Code:
// add $50 charge to Florida countries_id 223 and zone_id 18
if ($order->delivery['country']['id'] == 223 && $order->delivery['zone_id'] == 18) {
$inspection_fee = 50.00;
} else {
$inspection_fee = 0.00;
}
$methods[] = array('id' => $type,
'title' => $this->types[$type],
'cost' => (($cost + MODULE_SHIPPING_UPS_HANDLING) * $shipping_num_boxes) + $inspection_fee);
}
Or, if you need the Inspection fee to stand out, then you might want to build your own Orders Total module for it ...
