We report the spectral lag analysis for GRB 130313A (GCN Circ. 14293 & 14296)
based on the BAT data. Using 8-ms binned light curve, the spectral lag
for the 15-25 keV to 50-100 keV bands is 9.2 (+11.5/-7.7) msec.
These lag values place this burst in the short burst category. There is no evidence
for extended emission.
