7. 777 Definition of Serialized Item Management By UII SIM by UII: Management and tracking of a select population of items that have a unique item level traceability requirement –Unique item level traceability is defined as the requirement to trace lifecycle management events related to acquisition, property accountability, storage, operation, maintenance, safety, physical security, retirement, and disposal by each individual item –“Individual item” is defined as a single instance of a stock-numbered item or a single assembly/subassembly –The need for unique item level traceability requirement is determined by the manager of the item (materiel manager for consumables and PICA for reparables) –Existence of a manufacturer’s serial number does not constitute a requirement for SIM…must meet at least one of the following:  DoD serially-managed sensitive, DoD serially-managed critical safety, and/or DoD serially- managed pilferable items  All depot-level reparable items  Any items that the materiel manager or program manager decides require unique item level traceability In scope…secondary inventory governed by DoD 4140.1-R

8. 888 Definition of a DoD-Serially Managed Item An item of supply that has a unique item level traceability requirement, i.e. requires the capture and use of a unique item identifier during any lifecycle event related to acquisition, property accountability, storage, operation, maintenance, safety, physical security, retirement, and disposal by each individual item –“Individual item” is defined as a single instance of a stock-numbered item or a single assembly/subassembly –The need for unique item level traceability requirement is determined by the manager of the item (materiel manager for consumables and PICA for reparables) In scope…secondary inventory governed by DoD 4140.1-R

9. Uses of IUID in Supply Processes Receipt: Capture of UII(s) upon receipt enables traceability to physical location of goods as they travel through supply chain nodes. Receivers will collect the UII(s) from exterior packaging, validate them against the shipment status/notice, and store information in the appropriate business system. Acceptance: Acceptance by UII(s) enables visibility and traceability to custodial changes. Upon acceptance, any discrepancies will be recorded by UII(s). Store: Storage by UII is not required unless necessary to trace high intensity items in a facility. Issue: Issuing materiel by UII(s) enables traceability to the physical location of the UII(s) as goods travel to a downstream supply chain nodes. Wholesale and below wholesale activities will respond to requests by NSN/Quantity (MRO, LRO, RDO) and provide the UII(s) upon issuing materiel. This enables notification Inventory: Inventory by UII(s) enables synchronization and validation of owner and storage/managing activity records. The storage and/or managing activity will verify records by UII(s), and can provide history of balance affecting records by UII(s) to owners. Traceability throughout the supply chain 9 Note: Procedures for assigning IUID Designator FLIS Codes are not finalized

10. Manufacturers/ Suppliers WAWF Supplier enters item UII into WAWF, along with other shipment info 1 UID Registry WAWF sends UIIs to the UID Registry 6 WAWF sends advanced shipment notice to customer system, incl. the UII(s) (DLMS 856) 2 Distribution Depots DAAS 4 Customer performs acceptance, sending a transaction back to WAWF (WAWF 861) 5 Owner/ Manager DSS System will prompt user to collect AIT off the exterior of the package 3 8 *This depicts FOB Destination 7 WAWF notifies supplier of acceptance via email All business events impacting high-intensity managed items will be communicated to the Owner/Manager (DLMS 527R & WAWF 861) RECEIPT USING IUID: DLA Distribution Center receives new procurement items by UII from the commercial vendor* 10

11. Inventories are initiated by the Owner/Manager sending inventory requests (DLMS 846P) to WMS (depot or local system accountable record), or by the WMS based on schedule or other requirement e.g., denial. Inventory line item will be defined as stock number + supply condition code + UII. 1 DAAS Wholesale or below-wholesale activity Owner/ Manager When performing inventories, the WMS must verify, by physical location, all UII(s) against the accountable record and report differences to the owner/manager (DLMS 947I) Details for reporting UII differences to the owner/manager must be determined (e.g., when only UII has mismatches - no quantity or condition change) Mismatches on UII-- Causative research is required on any discrepancies found as a result of the inventory. 3 WMS or local system 2 Owner/Manager must verify reported UII against their record. Owner/Manager may request transaction history (DLMS 846P) for analyzing inventory discrepancies (WMS responds with the historical balance affecting transactions with all UII(s) included). UII mismatches require new reconciliation procedures between owner record and WMS accountable record. INVENTORY USING IUID: Wholesale and below-wholesale activities perform inventory 11

12. DLA Distribution Depot DAAS Owner/ Manager DSS DSS will issue items by NSN and ensure that UII(s) are included on the exterior package label 3 7 Maintenance Facility Service customer will send a requisition (DLMS 511R) for a quantity of an NSN (not by UII) to the owner/manager 1 Supply system DLA will send a MRC or Issue (DLMS 945A/867I) with UII(s) to the owner/manager 4 DLA will send a shipment status, incl. UII(s) to the customer (DLMS 856S) 5 Recipient performs a receipt, sending a transaction back to the owner/manager via DAAS, incl. the UII(s) (DLMS 527R MRA); generate an SDR if discrepant 6 All business events impacting high-intensity managed items will be communicated to the owner/manager (945A, 867I and 527R MRA) 2 Owner/manager will send a MRO (DLMS 940R) to the DLA Distribution Depot Maint. system “856S” “527R MRA” ISSUE USING IUID: DLA Distribution Depots issue items to customers based on receipt of a Materiel Release Order (MRO) 12

13. 13 Levels of Supply Management Intensity Standard-intensity serialized management by UII Items that have a lifecycle traceability requirement, but do not require management by eaches on a daily basis Managed by UII in accountable records (storage activity) DoD serially managed items that are sensitive or pilferable or DoD serially managed critical safety items or depot level reparables High-intensity serialized management by UII Items with a lifecycle traceability requirement, that are “micro- managed” today Managed by UII in accountable records (storage activity) and owner records (ICP) Nuclear Weapons-Related Materiel (NWRM) FLIS code under development will enable standard and high intensity

14. 14 Maintenance Activity Base 2 Owner/Manager Supply Activity Base 1 Report Worldwide inventory by NSN as “Qty of 3” (527R) Worldwide Inventory for owned materiel by NSN X and Qty NSN X - Qty 2 Location: Supply Base NSN X - Qty 1 Location: Maintenance Storage Activity Standard-Intensity Serialized Management Inventory by Qty (By UII is Optional) Receipt, Store and Issue by UII Report UIIs shipped (856S) Supply Base: Receipt, Store, Inventory and Issue for NSN X by UII Maintenance Base: Store UII at receipt, capture UII during repair action Validate correct UII received, Resolve UII mismatches, discrepancies Report UIIs shipped upon Materiel Return (856R) Mismatches are researched by UII Accountable Records By UII

16. 16 Identifying IUID Items- Proposed IUID Indicator Code Assigned to each stock number (NSN) requiring SIM using the UII, as determined by the manager of the item (Materiel Manager, with recommendation from the Engineering Support Activity, for consumables and the Primary Inventory Control Activity (PICA) for reparables) Indicates the level of management intensity required for the individual items within each IUID-eligible NSN –Standard-intensity serialized management by UII – managed by UII in accountable records –High-intensity serialized management by UII – managed by UII in accountable records and owner/manager records Provides for an optional interim IUID Code … –Applies to NSNs that require serial management by IUID but on which legacy assets on the NSN have not yet been IUID-marked –Enables the supply activity to manage the item by the NSN with the legacy serial number in the interim until all legacy assets on the NSN have been marked with a UII –Once the legacy assets on the NSN have been marked with a UII, the code values will be updated to full serialized item management using the UII

17. 17 Implementation of JLB Task Force Recommendations - Policy

18. 18 JLB IUID Task Force Conclusions JLB IUID Direction ~ Apr 2010 Apply UII to applicable legacy items IAW updated policy. Use UII for lifecycle management NLT 2015. Apply IUID management to intensively managed & tracked items (IIM, new and legacy): Small arms, NWRM, sensitive and classified. Pilferable and CSI over $5K. Apply UII to these new acquisition and legacy items: End items. Mission essential items. Reparable items. Serially managed items. GFP. Non-intensively managed consumables by RA discretion. All other items at discretion of requiring authority – achieve management goals and benefits in orderly, cost-effective manner. Services and DLA budget for implementation costs, prioritizing for non-recurring engineering for IUID BOTTOM LINE: Military & General Equipment: Current Policy Remains Secondary Inventory: Revise current IUID policy to focus on items with a unique item level traceability requirement

19. 19 IUID Memo for Secondary Items - Dec 2010 IUID Policy Revision Clarification Scope – DoD serially-managed secondary inventory: –Spare and repair parts that are serially managed by DoD –AA&E that are serially managed, but not managed only by lot –Small Arms –Depot Level Reparables (DLRs) –Other sensitive or pilferable or critical safety items that are serially managed by DoD –Other secondary items that require unique item level traceability Unit acquisition price requirement: –$5000 threshold no longer applies for legacy secondary inventory –$5,000 threshold still applies to new secondary inventory (DFARS being updated to synchronize new and legacy item IUID policy)

23. 23 Draft DoDM 4140.01-M Policy Volume 9 2. ITEM UNIQUE IDENTIFICATION (IUID) a. Required Procedures (1) In accordance with DoDD 8320.03 (Reference (h)), a unique item identifier (UII) shall be used for population of items that have a unique item level traceability requirement. (2) The primary purpose of UIIs is to enable more accurate engineering analysis and maintenance planning. Other functional areas may also benefit, including security, property accountability, safety, operational readiness, and warranty management. Instructions for constructing the UII are found in the “DoD Guide to Uniquely Identifying Items” (Reference (i)). (3) The DoD is transitioning from uniquely identifying items within an approved unique item tracking (UIT) program or serial number tracking (SNT) program to use of IUID for items identified in Volume 11 of this Manual as well as all items in approved serialized item management (SIM) programs. Previously approved UIT programs, such as the DoD Small Arms and Light Weapons Serialization and Navy Depot Level Reparable programs, shall continue under the purview of the Unique Item Tracking Committee, but should be transitioned to IUID management as soon as practicable. Use of local stock numbers in previously approved UIT programs will be discontinued. No additional UIT or SNT programs shall be approved.

24. 24 Draft DoDM 4140.01-M Policy (Vol. 9 continued) b. Implementing Procedures (1) The DoD Components shall: (a) Begin to transition from serially managing selected items using the manufacturer’s serial number to serially managing selected items using the globally unique and machine-readable UII (Construct #1 or #2 or acceptable equivalents) as defined in Reference (i). For unmarked existing items in inventory, installed, in use, or undergoing maintenance repair or overhaul, mark existing IUID required items as follows: 1. prioritize marking by most critical assets first: NWRM, critical safety items, sensitive, and pilferable. 2. mark items in inventory as criticality warrants it. 3. mark unserviceables only when inducted into repair. 4. mark items installed and in use only when removed and inducted into repair. (b) Develop the capability to exchange IUID data using Defense Logistics Management System (DLMS) transactions or Wide Area Workflow Property System Notices. (c) Place machine readable UII marks on the item itself or encode the UII on other permanent media (e.g., Data Matrix ECC 200, item identification labels) in accordance with MIL-STD-130 N (Reference (j)) as required. (d) Develop the capability to capture, retain, and provide current and historical data regarding uniquely identified tangible items by UII. (e) Develop the capability to use UII as a common key in functional databases to enable information sharing and information access to achieve collaboration between and among already existing, or emerging, item management systems.

25. 25 (2) All IUID implementations shall include provisions for data introduction and tracking using AIT. Business processes that include IUID capabilities shall use AIT devices that shall be capable of reading an ECC 200-compliant data matrix symbol from product markings, portable document format 417 barcode from unit or exterior packaging markings, or accompanying documentation. Information recorded in AIT devices shall be used to update automated information systems per serialized item management programs required by DoDI 4151.19 (Reference (k)). (3) The DoD Components shall ensure training is provided to personnel who perform functions affecting IUID and training courses are updated to teach current DoD policies and procedures. (4) The Director of the Defense Logistics Management Standards Office shall: (a) Require that DLMS be updated to provide full inter-DoD Component UII tracking capability and that applicable DLMS transactions require use of the UII. (b) Coordinate recommended changes to the DLMS to support IUID through the appropriate process review committee. Draft DoDM 4140.01-M Policy (Vol. 9 continued)

26. Draft DoDM 4140.01-M Policy (Vol 11) (3)Unique item level traceability is required for all DoD serially managed items that are also sensitive or pilferable, all DoD serially managed critical safety items and all NWRM using a Unique Item Identifier (UII) assigned to each individual item, i.e. a single instance of a stock-numbered item or a single assembly or subassembly. Unique item level traceability is also required for depot level reparables as well as any item that the materiel manager decides requires unique item level traceability. This requirement does not apply to items managed only by lot. Components shall begin to transition from serially managing these critical items using the manufacturer’s serial number to serially managing the items using the globally unique and machine-readable UII (Construct #1 or #2 or acceptable equivalents) as defined in the “DoD Guide to Uniquely Identifying Items” at the IUID website. 26

27. Draft DoDM 4140.01-M Policy (Vol 11 continued) While most items are accounted for by NSN, Components shall account for all DoD serially managed items that are also sensitive or pilferable, or DoD serially managed critical safety items or NWRM by UII within NSN or by serial number during the transition state until system changes implementing IUID are complete. These items shall be assigned a UII in accordance with DoD Instruction 8320.04 and a level of management intensity commensurate with the risk (high and standard). The Military Departments and DLA shall develop the capability to intensively manage these items as follows: (a) For high management intensity items (NWRM): 1. Receipt, issue, and inventory processes or balance affecting actions to both the storage site asset balance record and the materiel manager asset balance record, will be conducted by UII within NSN. 2. Issuing activities will provide shipment notification or shipment accompanying documentation to the recipient identifying the NSN and UII provided. 3. When wholesale stocks are issued, whether from stock or direct delivery, the recipient, in addition to updating asset records by UII within NSN, will acknowledge receipt back to the wholesale materiel manager by UII. 27

28. Draft DoDM 4140.01-M Policy (Vol 11 continued) (b) For standard management intensity items (DoD serially managed items that are also sensitive or pilferable or DoD serially managed critical safety and depot level reparables): 1. Receipt, issue or balance-affecting actions to the storage site asset balance record will be conducted by UII within NSN at the storage site. Physical inventory at the storage site can be performed by NSN or by UII within NSN. The materiel manager asset balance record will continue to be updated and maintained by NSN. 2. Issuing activities will provide shipment notification or shipment accompanying documentation to the recipient identifying the NSN and UII provided. 3. When wholesale stocks are issued, whether from stock or direct delivery, the recipient will update asset records by UII within NSN, but will acknowledge receipt back to the wholesale materiel manager by NSN only. 28

36. 36 Definitions for IUID Items High Intensity –Worldwide visibility and management of NSNs by UII where both owner and storage activities have visibility and traceability to the exact location of a serialized item in real time. Records between owner and storage activity are synchronized at least daily and differences reconciled by UII. Mismatches identified by receiving activities must be reported under Discrepancy Report business rules, and corrective action taken where appropriate. Standard Intensity –Visibility and management of NSNs by UII where only the local storage activity has visibility and traceability to the exact location of a serialized item in real time. The owner can query the local storage activity to locate the serialized item if required. Mismatches identified by receiving activities must be reported under Discrepancy Report business rules, and corrective action taken where appropriate.

37. 37 Proposed IUID Required Code - Details CODEEXPLANATION 1AHigh-intensity serialized management by UII. Worldwide visibility and management of NSNs by UII where both materiel manager and storage activities have visibility and traceability to the exact location of a serialized item in real time. Records between materiel manager and storage activities are synchronized at least daily and differences reconciled by UII. Mismatches identified by receiving activities must be reported under Discrepancy Report business rules, and corrective action taken where appropriate. 1BProposed High-intensity serialized management by UII (INTERIM). Applies to NSNs that require serial management by IUID but on which legacy assets on the NSN have not yet been IUID-marked in critical mass to allow system logic for supply chain management using the UII. This code will enable the storage activity to manage the item by the NSN in the interim until legacy assets on the NSN have been marked with a UII and contracts have been updated to include the IUID clause. Once the legacy assets on the NSN have been marked with a UII, the code value will be updated to full serialized item management by UII using the “1A” code value above. 2AStandard-intensity serialized management by UII. Visibility and management of NSNs by UII where only the local storage activity has visibility and traceability to the exact location of a serialized item in real time. The materiel manager can query the local storage activity to locate the serialized item if required. Mismatches identified by receiving activities must be reported under Discrepancy Report business rules, and corrective action taken where appropriate. 2BProposed Standard-intensity serialized management by UII (INTERIM). Applies to NSNs that require serial management by IUID but on which legacy assets on the NSN have not yet been IUID-marked in critical mass to allow system logic for supply chain management using the UII. This code will enable the storage activity to manage the item by the NSN in the interim until legacy assets on the NSN have been marked with a UII and contracts have been updated to include the IUID clause. Once the legacy assets on the NSN have been marked with a UII, the code value will be updated to full serialized item management by UII using the “2A” code value above.

38. 38 Definition of Principal & Secondary Inventory Items from 4140.1-R Principal Item –An end item or a replacement assembly of such importance to operational readiness that management techniques require centralized individual item management throughout the supply system to include items stocked at depot level, base level, and using unit level Secondary Item –An item that is not defined as a principal item and includes reparable components, subsystems, and assemblies, consumable repair parts, bulk items and material, subsistence, and expendable end items, including clothing and other personal gear
