How are time compliance technical order (TCTO) items identified on the item record?

Time Compliance Technical Order (TCTO) items are identified on the item record by using the Numeric Parts Preference Code (NPPC) set to 4. This specific code denotes that the item is subject to a compliance order that must be conducted within a specified time frame due to safety, operational, or maintenance requirements. The NPPC serves as a critical identifier that helps logistics personnel prioritize their tasks in the material management process.

In contrast, special handling requirements refer to additional instructions or conditions for particular items that need specific care while handling or storing but do not designate items as TCTO. The priority shipment code is utilized to indicate the urgency of shipment for items, but again, it does not classify items specifically as TCTO. The stock number suffix is used primarily for administrative purposes related to cataloging and inventory management but does not inherently indicate time compliance status.
