SPS standards, the commodity specific standards to protect domestic flora and fauna, are usually kept at prohibitively high levels, thereby inducing sub-optimal outcomes as an NTB. All the studies so far have overlooked the possibility of bilateral negotiations and studied the impact of SPS standards for a single commodity and on the importing nation only. The present research addresses this gap. A negotiation based SPS regime is considered, wherein a country may settle for lower benefits or a loss on trade of one commodity due to lower standards, yet a reciprocal change for another commodity may provide higher net gains.
