The Reciprocal Limitations Act requires Commonwealth Agencies to give preference to those bidders offering supplies produced, manufactured, mined or grown in Pennsylvania as against those bidders offering supplies produced, manufactured, mined or grown in any state that gives or requires a preference to supplies produced, manufactured, mined or grown to the detriment of Pennsylvania contractors. The amount of the preference is equal to the amount of the preference applied by the other state for that particular supply or service.

Contractor's that are non-resident bidders with a proposal greater than the minimum bid limit must complete and submit pages 3 and 4 of the form GSPUR-89 with their bid.
