Hi Anutara,
This kind of Bulk Q’ty gap between loading port vs. destination port is very common due to “liquid Bulk”s natural character.
Therefore Korea customs is accepting the shoretank outturn Q’ty based on SGS report and the ship owner also supported the BL adjustment accordingly.
Since the FTA benefits mainly belong to importer /destination country, would you possibility persuade your government officials to accept the revised BL Q’ty again?
