Hi I have a anchor bolt material and the supplier is saying that the steel is the world most recycle material. Modern steel production methods use at least 25% of recycled steel to make new steel.based on this they state that they hardware items and slotted channel alongs with anchors containing steel have a minimum recylced content of 25%. The steel used in these items are 100% recycled Hence they provide letter stating above and it also state that they product has 25% pre consumer and 100% post consumer, can this be letter acceptable as reliable and verified source or need more information from the supplier end to meet this credit

Sarfaraj - A letter from a supplier is typically good documentation but per your inquiry having 25% preconsumer and 100% post-consumer in the same product is not possible (equals 125%). Typically I use the default 25% post-consumer recycled content for steel materials that have low dollar values because it's not worth the time to track down the actual recycled content. Steel is the only material that LEED allows you to use a default recycled content without tracking down the exact content. Of course, recycled content could be higher than the default and for expensive items, it's worth getting accurate information from the supplier. (In this case, I don't think you have that.)
