An analysis of high-resolution VLT/UVES spectra of two B-type
main sequence stars, NGC 346-11 and AV 304, in the Small Magellanic Cloud
(SMC), has been undertaken, using the non-LTE tlusty model atmospheres
to derive the stellar parameters and chemical compositions of each star.
The chemical compositions of the two stars are in reasonable agreement. Moreover, our stellar
analysis agrees well with earlier analyses of 
regions. The results
derived here should be representative of the current base-line chemical
composition of the SMC interstellar medium as derived from B-type stars.
Key words: stars: abundances / stars: atmospheres / stars: early-type / galaxies: individual: Small Magellanic Cloud
