SUBSECTION 218.7

 OCTOBER 2011

DESTINATION VERIFICATION INSPECTION OF

STANDARD/VARIABLE NET WEIGHT ITEMS

I. PURPOSE AND SCOPE. This Subsection documents procedures for performing destination 

verification inspection of standard or variable net weight subsistence items procured on DLA 

Troop Support contracts. These procedures are applicable to Destination Quality Assurance 

Representatives (DQARs) performing on delivery at purchase (destination) inspection (class 4).

II. POLICY.

 A. DQARs shall perform a 100% inspection for verification of marked/required net weight 

whenever there is a suspicion that a grossly mismarked sampled unit may not be an isolated 

occurrence or at any time that 100% inspection does not impose too great a workload or cause 

unwarranted destruction of the product.

 B. Required calculations shall be accomplished as follows: 

Purchase Increment/ Weighing Increment

Marked Weight Minimum Degree of QAR shall weigh/report

Of Sample Units: Scale Sensitivity: to nearest:

Greater than 75 lb 1⁄2 lb whole lb

Greater than 10 lb to 75 lb 1⁄4 lb 1⁄2 lb

Greater than 1 lb to 10 lb 1/8 lb 1⁄4 lb

Greater than 8 oz to 1lb 1⁄2 oz 1 oz

Greater than 1oz to 8 oz 1⁄4 oz 1⁄2 oz

 1 oz or less 1/8 oz 1⁄4 oz

 C. Results of net weight verification inspections shall be recorded on DD Form 2393, 

Destination Verification Inspection of Standard/Variable Net Weight Items. Completed Form 

DD 2393 shall be filled with inspection records and not forwarded to the appropriate element 

performing the contract quality assurance function, (DLA Troop Support-FTW, DLA Troop 

Support-Pacific, or DLA Troop Support-Europe & Africa), unless specifically requested.

 D. When calculating the average unit net weight shortage, the quotient (number obtained when 

a number is divided by another) shall be calculated to four decimal places which shall be 

considered as the unrounded value.

 E. This Subsection does not apply net weight verification of fresh dairy products which is 

detailed in U.S. Army Health Services Command Regulation 40-28 or applicable Air Force 

directives.
III. DEFINITIONS.

 A. Actual Receipt. The total quantity tallied-in by receiving personnel minus any shortage 

found. If no shortage is found, the quantity received is the same as the tally-in quantity.

 B. Average Unit Net Weight Shortage. The total net weight shortage of all sample units 

weighed, divided by the number of sample units weighed.

 C. Grossly Mismarked Sample Unit. A sample unit which is found to be 10% or more 

shortweight or overweight.

 D. Homogenous/Fluid When Filled Products. Those products which are of uniform 

consistency throughout. “Fluid” at time of filling, refers to liquids or solid products (for 

example, shortening) which are heated and filled as a liquid.

 E. Insignificant Net Weight Shortage. A shortage in which the average net weight shortage is 

within acceptable sampling tolerances. (Refer to Encl 1, table E.)

 F. Net Weight Per Contract Unit. The specified/marked weight of the unit of purchase (e.g., 

item purchased in pounds, ounces, grams or containers of a standard of minimum weight).

 G. S-Factor. An allowance for sample variation.

 H. Range. The linear difference between the highest and the lowest numerical values in set of 

data, (e.g., the linear difference between + 3 and – 2 is 5).

 I. Significant Net Weight Shortage. A shortage in which the total dollar value of the net weight 

shortage exceeds the maximum limits that are consistent with acceptable risk. (Refer to Enc 1, 

table E).

 J. Standard Net Weight Items. Products packed in containers which have the same 

marked/required net weight (e.g., 60 pounds per shipping container, 5 pounds per package, etc).

 K. Tally-In. A total sum or marked net weights of individual units, pieces, shipping containers, 

etc., or the sum of the total number of units, pieces, shipping containers, etc. received. Tally-in 

is performed by receiving personnel.

 L. Total Net Weight Shortage. The total number of units in the lot, multiplied by the 

unrounded average unit net weight of a sample unit. A shortage exists when the actual net 

weight is less than the marked/required net weight, whereas an overage exists when the actual 

net weight is greater than the marked/required net weight.

 M. Variable Net Weight Items. Products packed in units which do not have the same 

marked/required net weight.

IV. SIGNIFICANT CHANGES: NA

V. PROCEDURES.

 A. Use of Scales.

 1. Scales to be utilized in performing net weight verification inspections shall be placed on a 

solid foundation and the accuracy verified against test weights of known accuracy prior to use. 

Scales to be utilized shall also be formally calibrated at a minimum frequency of once each 

calendar quarter.

 2. Scales with greater sensitivity than specified may be used if available, but the minimum 

degree of sensitivity of scales to be utilized in performing net weight verification inspections 

shall be as indicated in paragraph II.B.

 3. If the pointer stops between two subdivisions to the scale and is midway or above, record 

the higher weight, otherwise, record the lower weight (e.g., on a scale graduated in pounds, 

pointer midway or more between 10 and 11 pounds is recorded as 11 pounds).
 B. Determining Tare Weights.

 1. If tare weights are furnished on shipping containers/documents or if tare weight 

information provided is suspected to be in error, the DQAR shall establish tare weight as 

follows:

 a. If the item will not be rendered unserviceable, establish tare weight using a minimum of 

ten sample units unless otherwise specified in contractual documents. One hundred percent 

sampling shall be used for lots containing less than ten units.

 b. If the item will become unserviceable, establish tare weight using one sample unit for 

lots of less than 8.500 units or two sample units for larger lots, unless a larger sample size is 

directed by the accountable officer of DLA Troop Support-Subsistence,, DLA Troop SupportPacific, or DLA Troop Support-Europe & Africa, as applicable.

 c. If the DQAR finds that the tare weight as determined per paragraph V.B.1.a. or V.B.1.b. 

is insufficient for use in verifying net weight as required in this Subsection, the DQAR shall 

contact DLA Troop Support-Subsistence, DLA Troop Support-Pacific, or DLA Troop SupportEurope & Africa, as applicable, for further instructions on inspecting the particular 

item/shipment.

 2. Tare weights shall be consistent with the increment (degree of scale sensitivity) required 

for determining net weight.

 3. Glaze on waterfoods shall be included in determine tare weights. Bandage packaging 

material in which cheeses are cured shall not be included as part of tare weight determinations 

when delivery is made in the intact bandage material type packaging.

 4. Separate tare weights shall be established for each line item.

 C. 100% Verification Inspection of Standard or Variable Net Weight Items.

 1. Determine and record the actual net weight of each unit.

 2. Determine and record the total actual net weight of all units.

 3. Compare the total actual net weight of all units with the total marked/required net weight 

tallied by receiving personnel.

 a. If the total actual net weight is equal to or greater than the total marked/required net 

weight tallied by receiving personnel, there is no net weight shortage and no further net weight 

verification is required.

 b. If the total actual net weight of all units is less than the total marked/required net weight 

tallied by receiving personnel, determine the total net weight shortage and continue with step 4 

which follows.

 4. Round the total net weight shortage to the nearest weight increment.

 a. If the rounded total net weight shortage is zero, there is no net weight shortage and no 

further net weight verification is required.

 b. If the rounded total net weight shortage is not zero, refer to paragraph V.G. to 

determine if the total net weight shortage is significant.

D. Developing Sampling Plans For Other Than 100% Verification Inspection of Standard Or 

Variable Net Weight Items.

 1. When contractual documents contain sampling criteria for verification of net weights, that 

criteria shall take precedence.

 2. When contractual documents do not contain sampling criteria for verification of net 

weights, the following criteria shall apply:
 a. The lot size and sample units shall be expressed in the number of shipping containers, 

primary containers, etc., as appropriate.

 b. The sample size shall be the number of sample units indicated in Encl 1, Table C.

 3. DQARs are cautioned that the sample size required by paragraph V.D.1. or V.D.2. are 

minimum sample sizes. DQARs may increase the sample size when, for their professional 

judgment, increasing the sample size aids in performing the net weight verification inspection.

 4. Strict random sampling is not required; however, for results to be representative of the 

shipment, sample units shall be drawn from various locations throughout the load (i.e., rear, 

center, and front of load) and, if appropriate, from various locations within shipping and/or 

intermediate containers.

 E. Verification of Standard Net Weight Items.

 1. Determine and record the marked/required net weight, actual net weight, and the 

difference (over/short) between the marked/required net weight and actual net weight of each 

sample unit.

 2. Determine and record the total marked/required net weight, actual net weight and the 

difference (over/short) between the marked/required net weight and actual net weight of all 

sample units.

 3. Compare the actual net weight of all sample units with the total marked/required net 

weight of all sample units.

 a. If the total actual net weight is equal to or greater than the total marked/required net 

weight, there is no net weight shortage and no further net weight verification is required.

 b. If the total actual net weight is less than the total marked/required net weight, 

determine the average unit net weight shortage and continue with step 4 which follows.

 4. Round the average unit net weight shortage to the nearest weight increment.

 a. If the rounded average unit net weight shortage is zero, there is net weight shortage 

and no further net weight verification is required.

 b. If the rounded average unit net weight shortage is not zero, continue with step 5 which 

follows.

 5. Compare the average unit net weight shortage to the allowable limits in Encl 1, Table D.

 a. If the average unit net weight is equal to or less than the allowable limits in Table D, 

there is no net weight shortage and no further verification is required.

 b. If the average unit net weight shortage is greater than the allowable limits in Table D, 

continue with step 6 which follows.

 c. When net weights are measured in increments other than pounds (ounces, grams), the 

average unit weight shortage must be converted to pounds in order to determine if it is within the 

allowable limits of this table.

 6. Compute the total net weight shortage by multiplying the unrounded average unit net 

weight shortage by the total number of pieces (shipping containers, intermediate, primary 

containers) tallied by receiving personnel.

 7. Round the total net weight shortage to the nearest equivalent weight increment.

 8. Refer to paragraph V.G. to determine if the total net weight shortage is significant.

 F. Verification of Variable Net Weight Items.

 1. Determine and record the marked/required net weight, actual net weight, and difference 

(over/short) between the marked/required net weight and actual net weight of all sample units.
 2. Determine and record the total marked/required net weight, actual net weight, and the 

differences (over/short) between the marked/required net weight and actual net weight of all 

sample units.

 3. Compare the total net weight of sample units with the total marked/required net weight of 

all sample units.

 a. If the total actual net weight is equal to or greater than the total marked/required net 

weight, there is no net weight shortage and no further net weight verification is required.

 b. If the total actual net weight is less than the total marked/required net weight, 

determine the average unit net weight shortage and continue with step 4 which follows.

 4. Round the average unit net weight shortage to the nearest equivalent weight increment.

 a. If the rounded average unit net weight shortage is zero, there is no net weight shortage 

and no further net verification is required.

 b. If the rounded average unit net weight shortage is not zero, continue with step 5 which 

follows.

 5. Determine the range of differences between marked/required and actual net weights of all 

sample units.

 a. If there are both overages and shortages, the range is from the greatest overage to the 

greatest shortages.

 b. If there are shortages only, the range is from the greatest to the least shortages.

 6. Determine the Sample Allowance (S-Allowance) by multiplying the range by the Sample 

Factor (S-Factor) indicated in Encl 1, Table A for the appropriate sample size selected.

 7. For sample sizes larger than 104, S-Factor is applicable.

 8. Round the S-Allowance to the nearest equivalent weight increment.

 9. Compare the rounded average unit net weight shortage to the rounded S-Allowance.

 a. If the rounded average unit net weight shortage is equal to or less than the rounded SAllowance, there is no net weight shortage and no further net weight verification is required.

 b. If the rounded average unit net weight shortage is greater than the rounded SAllowance, continue with step 10 which follows. 

 10. Compute the total net weight shortage by multiplying the unrounded average unit net 

weight shortage by the total number of pieces (shipping containers, primary containers,

carcasses, etc.) tallied by receiving personnel.

 11. Round the total net weight shortage to the nearest equivalent weight increment..

 12. Refer to paragraph V.G. to determine if the total net weight shortage is significant.

 G. Determine If Net Weight Shortage Are Significant.

 1. Compute the total dollar value of total net weight shortage by multiplying the rounded 

total net weight shortage by the contract unit cost (price per pound, package, gallon etc.,). 

DQARs are cautioned that for certain products (e.g., oil), it is necessary to convert the total 

weight shortage from pounds to the number of appropriate contract units short (e.g., gallons, 

quarts) prior to computing the total dollar value of the shortage.

 2. Compare the total dollar value of the total shortage to the maximum limits in Enc 1, Table 

E. Verification of Standard Net Weight Items. 

 a. If the dollar value of the shortage is equal to or less than the maximum limits in Table 

E, there is no significant net weight shortage and DQARs need not increase the frequency of net 

weight verification inspections. DQARs would then report the rounded total shortage to the 

Receiving/Accountable Officer so that the shortage can be deducted from the contractor's 

invoice/manifest.
 b. If the dollar value of the shortage is greater than the maximum limits in Encl 1, Table 

E, there is a significant net weight shortage which must be reported as a nonconformance in 

accordance with the procedures detailed in Subsection 209.1. Significant net weight shortages 

are sufficient cause to increase the frequency of net weight verification inspections in order to 

protect the Government's interests.
