There's no need to import 'import' since you're inheriting:

use Exporter;
our @ISA = qw(Exporter);
our @EXPORT = qw();
our @EXPORT_OK = qw();

Alternatively, if you don't like inheriting from Exporter:

use Exporter;
our *import = \&Exporter::import;
our @ISA = qw();        # nope, no Exporter
our @EXPORT = qw();
our @EXPORT_OK = qw();
