"Huabeisaurus" has never been incorporated into a cladistic analysis, but several authors have commented on its affinities on comparative grounds. Buffetaut "et al." reviewed the sauropods of Thailand and described Late Jurassic and Early Cretaceous teeth similar to those of euhelopodids (in the traditional sense, i.e., "Euhelopus", "Mamenchisaurus" and "Omeisaurus") and others more reminiscent of "Nemegtosaurus" and "Phuwiangosaurus" (which they termed nemegtosaurids). Following these comparisons, "Huabeisaurus" was regarded as a nemegtosaurid by Buffetaut "et al.". Upchurch "et al." considered "Huabeisaurus" to represent a titanosauriform or titanosaur outside of Lithostrotia on the basis of a variety of features. You "et al." suggested a close relationship between "Huabeisaurus", "Borealosaurus", and "Opisthocoelicaudia". Mo "et al." highlighted similarities among "Huabeisaurus", "Fusuisaurus", and "Sonidosaurus". Tanimoto "et al." considered "Huabeisaurus" to be closely related to "Nemegtosaurus", "Borealosaurus" and the “Toba sauropod” of Japan (as members of Nemegtosauridae). Finally, it has recently been suggested by D'emic "et al". that "Huabeisaurus" is a member of Euhelopodidae.
