We study uncertainties of the predicted inclusive Higgs production crosssection due to the uncertainties of parton distribution functions (PDF).Particular attention is given to bbH Yukawa coupling enhanced productionmechanisms in beyond SM scenarios, such as MSSM. The PDF uncertainties aredetermined by the robust Lagrange Multiplier method within the CTEQ globalanalysis framework. We show that PDF uncertainties dominate over theoreticaluncertainties of the perturbative calculation (usually estimated by the scaledependence of the calculated cross sections), except for low Higgs masses atLHC. Thus for the proper interpretation of any Higgs signal, and for betterunderstanding of the underlying electroweak symmetry breaking mechanism, it isimportant to gain better control of the uncertainties of the PDFs.Comment: LaTeX, JHEP, 19 pages, 14 figure
