Is it possible to change or revise details in Bill of lading - after vessel sailed from port of loading ?

HI 

Possible for HBL only and in MBL 

Yes it is possible. You just have to approach carrier/ Forwarder for amendment and they will charge amendment charges for same

Yes, it is possible if bothe parties (buyer and seller) are agreed and must to do before reaching the shipment to its destination port just avoid any delays in custom clearance.

Sure....all u have to do is to amend the changes made from the original Bill of Lading to the New bill of Lading

Yes it is allowed withe charge applicable but is not possible incase of the LC stipulate "The stale documents are not allowed" 

no it is not allowed to change or revise details in B/L after sailing unless agreed by owners

yes it's possible to change or revise it

Yes, but in some cases not allowed, because if this document required under L/Cs and the L/Cstipulates "The stale documents are not allowed" 

Yes, it can be . but there are risks if the re-issuing BL is late, you will be pay more.

waiting for DO will be more costing (Detention fees, amended charges ..ect)

Also, It depends on  certification & classifcations of vessels and some agreement conditions will help.

YES, WE CAN CHANGE THE DETAILS BUT SHIPPING LINE WILL CHARGE FOR THIS.

If any details to be amended have not been mentioned in export shipping documents, the carrier can not amend bill of lading. In such cases, exporter or his customs broker need to amend the said shipping documents with customs firstly and after completion of such amendment in shipping bill, he can approach shipping liner(carrier) to amend Bill of Lading accordingly, If an amendment is required once after submitting original bill of lading with shipper’s bank, the overseas buyer can amend the said original bill of lading once after receiving BL from his bank through shipper’s bank. At this time, the consignee needs to approach the shipping liner’s counter part office at consignee’s location. The carrier (shipping company) at consignee’s location needs a ‘No Objection’ letter or message to amend bill of lading from his counter part at load port who issued Bill of Lading. In turn, the shipping company at load port confirms the details to his counterpart at destination regarding amendment of BL. The freight forwarder at load port provides ‘no objection’ up to the extent of information available in export shipping bill submitted by exporter. If consignee needs to amend any details other than the details declared in export shipping bill, the exporter (shipper) can amend shipping bill at load port with customs and submit such amended shipping bill with shipping company , so as to enable him to send a ‘no objection’ to amend such information to include in bill of lading.
