Confirmed it does not, there is an enhancement request and workaround. Do not know how often these tables are updated to know if this is feasible.
Scenario
User wants to Set Up UPS Surepost in NetSuite
Solution
Currently NetSuite does not have an UPS SurePost Shipping option as this is covered on Enhancement # 213226. An alternate solution is to ask UPS for a spreadsheet on how SurePost charges on Shipping based on weight. Then create a new Shipping Item and use Shipping Table to charge for shipping.
