The first bill I brought forward that I was the officer on dealt with the amendments to corporate criminal liability, back in 2003. The section for dealing with corporate liability—“organizations”, they're called—for offences requiring intention envisions there being somebody in the corporation who, with the intention to profit the corporation, does something that's forbidden, and the responsible senior officer of the corporation either colluding in it or turning a blind eye to it or being so negligent that they allowed it to happen.
So yes, I believe a corporation that happily shipped off huge barrels of stuff that can be used to manufacture meth or other drugs could be found to know that it's going to be so used, and I think a charge could be made against them. They'd almost undoubtedly be in violation of various regulations as well. There's no reason on earth why a corporation could not be caught on this.
