Proceeds from the sale of ICs would encourage exporters (who would gain that extra money in addition to the proceeds of their exports) and discourage importers (who would need to pay the additional cost to acquire ICs as well as the cost to acquire the goods they are importing).
Sales revenue from integrated circuits would encourage exporters, who would gain an extra profit on top of their existing export earnings. Conversely, it would discourage importers, who would have to pay a higher price for ICs and the costs associated with importing the goods they bring into the country.
