Wrong CTH mentioned in BOE by Fedex

make a practice to assess the draft BOE before it is filed.

Any ways, if the goods are not yet cleared, then you have one option which may be cumbersome. 

Section  149 - amendment of BOE. Section re-produced as under;

"149. Amendment of documents.—Save as otherwise provided in sections 30 and 41, the proper officer may, in his discretion, authorize any document, after it has been presented in the customs house to be amended: Provided that no amendment of a bill of entry or shipping bill or bill of export shall be so authorized to be amended after the imported goods have been cleared for home consumption or deposited in a warehouse, or the export goods have been exported, except on the basis of documentary evidence which was in existence at the time the goods were cleared, deposited or exported, as the case may be."

If duty already paid, then amend the BOE and claim for refund. There are several case studies and supreme cour judgement in this regards which may be relied upon.

it is the duty and responsibility of the Assessing Officer / Assistant Commissioner to correctly determine the duty leviable in accordance with law before clearing the goods for Home consumption.

Section 149 of the Act does not prescribe any time limit for amending the Bill of Entry filed and assessed

Thank you sir for your kind reply..

Fedex had already paid the duty to custom without informing us the duty amount and the parcel is at destination warehouse of fedex...

And fedex is asking us to pay full duty to release the parcel.

Fedex is the most unprofessional Courier company and do not follow any regulations. Last time I had to face ED interrogations because they cleared my paid shipment as free courier sample and I could not show the value in BOE. Had three shipments to account for . Funny thing is the total value of the shipments were around  600 Euro but had to pay a penalty of 77000 even though the error was committed by courier company. 

Recently also Fedex brought in two shipments without adding freight in the BOE. I may again have to pay penalty. Have taken a clear decision no more shipments through Fedex.  That's the only way to avoid future issues
