If what we're doing by changing an explanatory note is having the effect of changing the tariff rate--in this case, changing it from where it's classified now in chapter 35, under a 6.5% tariff, and moving it to chapter 4, which would classify it under a 270% tariff--and raising the tariff for those products, then that would require a legislative amendment. There's no provision within the tariff to allow the Minister of Finance to recommend such a change.
