Section 338 Canada T-Minus 7: Why CAPE Phase 2 in ACE Is the Primary Refund Pathway if Your Broker Mis-Coded the Form 214 Admission

Section 338 duties on covered Canadian-origin imports take effect at 12:01 AM EDT on August 19 2026 under the three July 20 2026 Presidential Proclamations (11061, 11062, and 11063) and their Annex II subheading lists. Seven days out from the effective instant, CBP has still not published a CSMS message covering implementation. For importers whose FTZ operator has already refused to code Form 214 admission under Privileged Foreign this week, or whose broker will guess at Chapter 99 heading assignments on post-August 19 entries because CBP has not published Chapter 99 numbers for Section 338, the primary refund pathway is CAPE Phase 2 in ACE.

The CAPE Phase 2 Expansion

CBP launched CAPE (Cargo Automation and Post-Entry) Phase 1 in 2024 as the ACE module for Post Summary Correction filings under 19 CFR 141.111. Phase 1 covered basic PSC scenarios: misclassification correction, quantity adjustment, valuation correction on non-reconciliation entries. Phase 2 launched on April 20 2026 and materially expanded eligibility.

The April 2026 expansion added:

• Reconciliation-flagged entries. Previously, an entry flagged for reconciliation had to wait for the reconciliation entry to close (typically 21 months after entry summary) before any correction could be filed on the underlying entry. Phase 2 allows PSC on the underlying entry while reconciliation remains open, provided both filings cross-reference.
• ADD and CVD determinations pending. Entries flagged for post-entry ADD or CVD assignment can now be corrected on the base HTS or country-of-origin question without waiting for the AD/CVD determination.
• Rate-assignment pending entries. This is the category most relevant for Section 338 Canada. Entries filed after August 19 that carry Section 338 duty coded by best-guess Chapter 99 heading (because CBP has not published the Chapter 99 numbers) can be corrected through CAPE PSC once CBP publishes the numbers, without waiting for liquidation.

Why 1520(d) Is Not the Right Vehicle for Section 338 Errors

The reflex refund pathway many importers assume for USMCA-qualifying Canadian goods is 19 USC 1520(d), the post-entry FTA-preferential-treatment claim mechanism. That pathway is available for goods where the importer paid MFN duty at entry and later documented USMCA (or other FTA) qualifying origin, allowing a refund of the MFN duty back to zero.

Section 338 duties do not waive under USMCA. The July 20 2026 proclamations cover goods that continue to originate from Canada under USMCA rules of origin but nevertheless carry the 50 percent Section 338 layer. Motor vehicles, dairy, alcoholic beverages, wine, cement, furniture, fishing rods, seeds, clothing, wigs, hockey equipment, and other Annex II subheadings are all in this bucket.

Filing a 1520(d) claim asserting USMCA preferential treatment on a Section 338 covered good would not produce a refund because the FTA preference does not apply to the Section 338 layer. The correct vehicle is a CAPE PSC filed under 19 CFR 141.111 asserting the specific error being corrected (FTZ PF election date, Chapter 99 heading assignment, admission date, tier assignment for goods subject to multiple 338 tiers).

CAPE PSC Mechanics

The CAPE PSC filing window is 314 days measured from the date of the entry summary filing. For a Section 338 covered good withdrawn from FTZ or bonded warehouse on August 25 2026, the entry summary date is typically the same as the withdrawal date, so the PSC window closes on approximately July 5 2027.

Filing steps:

1. Broker (or supplemental filer) logs into ACE and opens the CAPE module.
2. Broker identifies the entry summary by entry number and date.
3. Broker selects PSC filing type (classification correction, rate correction, valuation correction, quantity correction, origin correction).
4. Broker uploads supporting documentation: invoice, packing list, HTS classification memo, admission records for FTZ cases, 146.3 escalation letter and port director response if applicable.
5. CBP CAPE workflow reviews the PSC and either accepts (refund lands to IOR ACH account within 30 to 60 days of acceptance) or rejects (with reason code that the broker can address on refile or that becomes the basis for a 19 CFR 174 protest at liquidation).

Interaction With 19 CFR 174 Protest

CAPE PSC and 19 CFR 174 protest are sequential vehicles, not parallel. CAPE PSC files any time within 314 days of entry summary and before liquidation. Once the entry liquidates (typically 314 days after entry summary if no extension), the PSC window closes and protest becomes primary. Protest window is 180 days from liquidation.

The correct sequence for a Section 338 mis-coding error:

• Identify the error as early as possible (weeks after withdrawal, not months).
• File CAPE PSC immediately with full documentary support.
• Wait for CBP acceptance or rejection (typically 60 to 120 days).
• If accepted, refund lands to the IOR ACH account.
• If rejected, file a 19 CFR 174 protest within 180 days of liquidation citing the CAPE PSC rejection reason and adding any additional legal argument (for example, a 146.3 port director determination that landed after the CAPE PSC was filed).

Filing both simultaneously creates a filing conflict that CBP will resolve by suspending the protest until the PSC is dispositioned.

The 500k CIF Ontario Furniture Recovery Scenario

Take a 500k CIF furniture entry from Ontario on HTS 9403.30 (wooden office furniture), USMCA qualifying. The importer's FTZ operator refused to code Form 214 admission under Privileged Foreign because they wanted CSMS guidance first. The importer sent a 146.3 escalation letter to the Area Port Director on August 12 2026. The port director had not responded by August 15 when the shipment needed to admit. The operator coded under generic Foreign status. Goods withdrawn from FTZ on August 25 2026.

Duty at withdrawal:

• USMCA MFN: 0 percent
• Section 338 layer: 50 percent stacked over base
• MPF: 0.3464 percent capped at 634.62
• HMF: 0.125 percent (on port cargo)
• Total: approximately 251,260

Pre-August 19 rate if PF election had been coded at admission:

• USMCA MFN: 0 percent
• No Section 338 (locked to admission date rate)
• MPF: capped
• HMF: 0.125 percent
• Total: approximately 1,260

Delta: 250,000 recoverable through CAPE PSC.

CAPE PSC filing (September 2026):

• Entry number and date: withdrawal entry summary from August 25 2026.
• Correction type: rate correction and admission date correction.
• Basis: 19 CFR 146.41(e) PF election should have applied at admission date August 15 2026, rate lock at pre-August 19 zero-duty position, operator refused to code PF pending CBP CSMS guidance which never landed, 146.3 escalation letter of August 12 2026 documents importer-side effort to elect PF at correct time.
• Supporting documents: original Form 214 filing, 146.3 escalation letter with certified mail receipt, port director response letter if received by PSC filing date, entry summary from withdrawal, USMCA certificate of origin.

If the 146.3 letter response lands supportive (port director confirms operator should have coded PF), CAPE PSC typically clears in 60 to 90 days with full 250,000 refund to IOR ACH. If the port director response is unclear or lands after the PSC decision, CBP may hold the PSC pending the port director determination. If CBP rejects the PSC, file 19 CFR 174 protest at liquidation citing the 146.3 record.

What to Do This Week

• If your broker has not confirmed CAPE Phase 2 capability, ask for their CAPE ACE user credential setup date. Phase 2 launched April 20 2026 so any broker credential from that date or later is Phase 2 capable.
• If you have Section 338 Canada exposure and your FTZ operator is asking for CSMS before coding PF, file the 146.3 escalation letter to the Area Port Director this week. The letter creates the contemporaneous record CAPE PSC will need if the goods clear post-August 19 without PF election.
• If your broker files corrections exclusively through 19 CFR 174 protest at liquidation, evaluate whether the 314 to 500 day refund cycle acceleration from CAPE PSC justifies engaging a supplemental filer for the correction workflow.
• Track CBP CSMS publication for Section 338 Chapter 99 heading numbers. Once published, CAPE PSC filings can cite the specific Chapter 99 heading assigned to the Section 338 layer, which strengthens the PSC record.
