TikTok Shop Updates Delayed Delivery Rate (LDR) Calculation Rules
TikTok Shop has revised the calculation logic for the Delayed Delivery Rate (LDR) to include 'overdue undelivered' orders. This change aims to enhance fulfillment transparency. Sellers must optimize inventory and logistics processes before enforcement begins in July, or risk facing traffic limitations and advertising disruptions.
What are the key facts?
- 1Effective Date: June 15, 2026
- 2New Formula: (Overdue Orders + Overdue Undelivered Orders) / Total Orders within Assessment Period
- 3Enforcement Grace Period: until July 2026
What happened?
On June 15, 2026, TikTok Shop updated the LDR calculation formula, now accounting for both overdue orders and those not shipped beyond the SLA timeframe. This policy aims to improve fulfillment performance and, although currently in a transition phase, will formally implement penalties from July.
What does this mean for cross-border sellers?
Sellers should immediately check inventory synchronization efficiency to avoid prolonged 'undelivered' statuses from stock shortages, which could worsen LDR metrics and negatively impact shop ranking and ad spending.
