There are legitimate exceptions to the policy on TDD standards for DVD contracts. Contracting officers should recognize the following as examples of appropriate exclusions from TDD standards:
1) Planned DVD contracts for kits used by maintenance depots.
2) Planned DVD items for commercially available items (household/general purpose items only) where the vendor can support a contract delivery date not more than 3 days greater than the TDD Total Order-to-Receipt Time (TORT);
3) Planned DVD contracts for a specific customer requiring support that is less demanding than the TDD standards;
4) Planned DVD contracts for part numbered items (those with no NSN).
5) DVD contracts/orders for non-stocked items (Acquisition Advice Code (AAC) “J” which is not stocked, centrally procured non-stocked items). Although TDD guidelines do not apply to this type of support, expedited delivery is still a critical requirement for non-stocked high priority requisitions. DVD arrangements must recognize urgency of need, item criticality, and weapon system coding, if applicable. Both Administrative Lead Time and Procurement Lead Time must be minimized.
The above exclusions do not apply to support for items assigned AAC D (DOD Integrated Materiel-Manager (IMM) stocked and issued) and AAC Z (Insurance/Numeric Stockage Objective item). These items must meet appropriate TDD pipeline standards. DLA customers will expect support for planned DVDs as quickly as they are supported from stock. The TDD pipeline standards are DoD Components targets that shall be met or improved upon whenever physically and economically feasible. More stringent time standards may be adopted for individual pipeline segments controlled by DLA when subsequent savings in time and improved service can be achieved.
It is recognized that several Defense Supply Centers’ (DSC) order processing systems currently use Issue Priority Group (IPG) codes in assigning delivery dates - not category requisitions (categories 1-3) referenced in DoD 4140.1-R. We expect that this condition will be corrected through business system modernization efforts. Due to anticipated time and costs required to update current systems, DSCs are authorized to continue using IPG codes in assigning delivery dates until business system modernization changes are finalized.
