Several listings which offered embers and “a section of timber” from the remains of Notre Dame Cathedral have been removed from eBay.
The auction site has also taken down adverts for T-shirts with the slogan "Je Suis Notre Dame" under a policy against items which "profit from human tragedy or suffering”.
An advert offering "embers from the Notre Dame fire" was posted to the auction site on Tuesday following the blaze less than 24 hours earlier.
The company removed the advert, which included a generic photograph of a burning log, after it was asked by the Press Association whether such listings were acceptable.
T-shirts advertised as "Fire Remember Tops" were also deemed to have breached the company's disaster and human tragedy policy.
The listing for the section of timber, posted under the username s55dvl_9, included the message: "Grab a section of timber from the fire.”

Bidding was started at 99p and the listing said the item would be posted from the UK "with Royal Mail 2nd Class Letter" for a fee of 61p.
An eBay spokesman said: "eBay does not tolerate the sale of any item that seeks to profit from human suffering or tragedy and this listing has been removed.”
The company also confirmed that the T-shirts, posted under at least 14 separate listings, were removed under the same policy.
Sellers who post such items are given a warning and repeat offenders can have their accounts suspended.
The company has conducted regular scans for similar items posted following the fire and said it will continue to monitor listings.
The firm's policy permits items related to natural disasters which have "substantial social, artistic, or political value", according to its website.
"Charity websites or charity listings set up to benefit the victims of a disaster or tragic event" are also allowed.
It bans "listings and products that graphically portray, glorify or attempt to profit from human tragedy or suffering, or that are insensitive to victims of such events".
