At least two bid samples should be submitted by each bidder at bidder's 

 expense. One sample should be cut and the other should be retained by the 

 purchaser if the bid sample opened is found to be acceptable. The retained 

 sample should be cut if the delivery does not comply with specifications. If 

 requested, samples submitted by unsuccessful bidders should be returned to the 

 bidder at his expense. 



Each sample should be plainly marked with the bid item number, name of 

 product, name of bidder, and other pertinent information. A list of the samples 

 being sent should accompany the bid; a carbon copy of this list should be 

 enclosed in the package containing bid samples. Unless such lists are properly 

 filled out, unaccepted samples should not be returned but should be disposed 

 of in the manner deemed advisable. If samples of more than one class of 

 merchandise are packed in a single package, each class of samples should be 

 wrapped and marked separately or should be placed in separate compartments 

 and distinctly marked. 



Cases containing bid samples should be plainly marked "samples" with the 

 name of the bidder in the upper left-hand corner, and should be addressed to 

 the purchasing agency. All charges for transportation of samples, including 

 cartage, should be prepaid by the bidder, and no package of samples should be 

 accepted unless these charges have been prepaid. 



Proposals should not he enclosed in the package containing hid samples. 

 Envelopes containing bids should be sealed and marked in the upper left-hand 

 corner with the name and address of the bidder and should be addressed to the 

 purchasing agency. The date and hour of opening of the bids should also 

 be shown. 



B. Final Inspection of Deliveries 



Inspection at destination by a qualified person to determine whether or not 

 delivery conforms with requirements of the specification should entail little 

 difficulty. The contractor may provide that the vendor be required to submit 

 the certificate of grade of the United States Department of Agriculture to 

 substantiate his claim of the grade offered. 



1. The certificate of grade of the United States Department of Agriculture 

 may be used as evidence of good delivery, provided the certificates bear a date 

 not more than 60 days prior to date of delivery and there is satisfactory 

 evidence to indicate that the identical lot originally graded is the lot delivered. 



Ordinarily the identity of a delivery may be established by the following 

 evidence: 



a. If delivered merchandise bears embossed code marks identical with those 

 on goods originally graded. 



b. If certificates of grade are accompanied by certificates of loading or 

 other evidence denoting subsequent shipment of lots covered by certificates 

 of grade. 



With satisfactory evidence Indicating that the goods are those from which 

 samples were originally drawn and graded, inspection at destination should 

 not be necessary. 



Merchandise bearing the Department's shield, which denotes that the grade 

 has been certified and that the product has been packed under continuous 

 factory inspection, need not be subjected to further inspection. 



In the event that a question arises as to whether delivery has been made 

 from the lot originally graded or if there is evidence that substitution has been
