19 USC 1520(d) vs CAPE PSC vs 19 CFR 174 Protest Decision Tree for Post-Section 338 Recovery, Choosing the Right Pathway by Entry Status, Liquidation Timing, and Chapter 99 Heading Dispute Type

After a Section 338 Canada entry has been filed and CBP has assessed the 50 percent additional duty at Chapter 99 heading 9903.03.12, 9903.03.13, or 9903.03.14, the importer has three recovery pathways depending on entry status and dispute type. 19 USC 1520(d) Post-Summary Correction filed via CAPE Phase 2 in ACE works within 314 days of entry summary for unliquidated entries. 19 USC 1520 Reconciliation works for entries flagged as reconciliation candidates pending underlying determinations. 19 CFR 174 protest at liquidation works within 180 days of liquidation notice for liquidated entries. This decision tree walks each pathway with entry status prerequisites, filing mechanics, refund timelines, and the specific dispute types each pathway can and cannot address for Section 338 recovery.
