Others may have a view, but it appears that tolerance has only been applied to the LC value, but there is no indication that it is also to apply to the quantity.

Had the quantity been expressed as anything other than individual items (i.e weight or measurement), then you would have been able to exercise the provisions of sub-art 30 (b) of UCP600, which would have allowed you to ship up to an extra 5% in quantity (provided  the 105% of LC value was not overdrawn). But in this specific case, you cannot exercise this option, so would suggest that you request an amendment to allow the tolerance to also apply to the quantity.  Otherwise, the bank would be obliged to raise a discrepancy of overshipment of goods.
