The asymmetric unit of the title compound, C14H2Cl4F3NO2, contains two independent mol­ecules. In each mol­ecule, the phthalimide ring system is nearly planar [maximum atomic deviation = 0.031 (2) or 0.038 (2) Å] and oriented with respect to the benzene ring at 65.04 (7) or 71.76 (10)°. Weak inter­molecular C—H⋯O and C—H⋯F hydrogen bonding is present in the crystal structure.
