We  have  done  our  very  best  in  the  manufacture  and  packing  of  this  material.  The 

transportation carrier is now responsible for delivering it to you in its original good condition,

delivery receipt and the freight bill, or by special form provided by United Parcel or the Post 
Office. 
 

The  Interstate  Commerce  Commission  has  ruled  that  Transportation  Companies  will  not

of delivery.  It  is  the buyer’s responsibility to  make a complete inspection immediately upon

Bill  of  Lading  –  or  in  damaged  condition  –  without  having  proper  notation  made  by  the 
Carrier, you do so at your own risk. 
 

If  bundles  or  crates  are  in  apparent  good  order,  but  on  opening  contents  are  found  to  be 

damaged, call Carrier for adjuster to view same and have the Transportation Company/United

not be deducted from out invoice, nor pay of the invoice withheld awaiting adjustment of such
