Word "about" in packing unit's description

[AgeTrink]

Hi, colleagues.
There is a brainteaser for you regarding a condition describing how the goods have to be packed.
LC reads: "Goods must be packed in new strong PP bags of about 45 kgs or 50 kgs each net and packing list to certify the same".
Now there is a question how to interpret the word "about" in the context. Art 39/a refers only to amount of credit, goods quantity and unit price, not to packing unit's size.
Therefore how would you check the packing list? Must all packs be of size exactly 45 or 50 kgs or is there any tolerance allowed?
I have no idea what to say to our (export) client.

if no total quantity is evidenced udner l/c (goods description) and unless l/c ask for a detailed p/list, p/list could only evidence (among others):"goods are packed in new strong PP bags of about 45 kgs and 50 kgs each net"(if both are shipped.otherwise should evidence only the kind of bags shipped,either of 45 kgs or of 50 kgs).
if l/c states a total quantity and a detailed p/list is presented, 39a is applicable (45 kgs +/-max.10% and/or 50 kgs +/- max.10%).

In this context I would rather understand that the tolerance should be between 45kg and 50kg, i.e. in packing of not less than 45kg and not more than 50kg

Dear Age,

Guessing the intention of this, would be … guessing

My suggestion would be to ask the issuing bank for clarification. Perhaps considering asking the beneficiary – and if that results in a reasonable and solid “interpretation” then I would consider following that … depending on the customer, the transaction and the LC.

Best regards
Kim

Thank you all.
In fact we stopped guessing and asked for a clarification. And this clause was then removed entirely.
But the question still remains.. Hopefully there will be no similar cases in the future
