Regarding ISO was already expired, Do you have update ISO ?
For Thailand customers (Pure Chemicals, Wang Chemicals, Monexco, F-Plus), they need the original stamp and sign from BRC to clear the cargo instead first if ISO is not already.
Could you please send (old 3 copies + New requested 4 copies) = total 7 copies by urgently : Original , stamp and sign of new ISO (If you have) or BRC and If when you send already please let me know about courier detail.
