I am not a trade lawyer - but I think this is logical. If a market imposes the same tax to ANYONE selling in it, irrespective of origin, based on the quality or type of product, then it is not a 'tariff' (an unequal tax based on origin country) but a market tax. Thus a tax based on the waste-handling cost for ineffective packing or non-durable uses of difficult to re-manufacturer resources could be an effective way of pricing the damage to the commons back on to the individual actors at a point where change can occur because of the pressure.
