Refunds are live. Brokers aren’t filing.

CBP’s CAPE Phase 1 refund portal opens at 8:00 AM ET Monday morning — the first real operational path for SMB importers to recover IEEPA duties paid since April 2025. Refunds are opt-in, eligibility windows are narrow, and CBP has quietly killed the PSC workaround most brokers have been using. What you do this week decides whether your money comes back in 60–90 days, drifts into Phase 2 (no timeline), or never arrives.

3 moves to make this week.

CAPE opens Mon, Apr 20 · 8:00 AM ET · the 180-day clock is the one that bites

Mon, Apr 20 CAPE Phase 1

File your CAPE Declaration on day one.

Up to 9,999 entries per submission. Covers unliquidated entries and anything liquidated within the last 80 days — back to roughly Jan 30, 2026. Refunds ACH-only, 60–90 days after acceptance. Don’t wait for your broker to suggest it.

File §1514 protests on the 80–180 day bucket.

Entries liquidated more than 80 days ago but still within the 180-day protest window fall outside CAPE Phase 1. Phase 2 has no timeline. A protective protest is your only backstop — and the move most brokers won’t flag for you.

Kill any PSC filed for IEEPA refunds.

CBP has instructed filers that Post Summary Corrections will not be accepted for IEEPA refunds. Centers of Excellence are denying them. If your broker filed a PSC expecting a refund, pull it and route through CAPE. Full stop.

Section 122
The Call of the Week

The 80-day window inside CAPE Phase 1 leaves a second cliff most brokers won’t flag — and the only fix is a §1514 protective protest, this week.

Phase 1 covers unliquidated entries plus anything liquidated within 80 days of your CAPE filing. Anything outside that window falls into Phase 2 — and Phase 2 has no published timeline.146 For entries liquidated more than 80 days ago but still inside the 180-day protest window (roughly Q4 2025 entries), the only refund mechanism if Phase 2 stalls is a §1514 protest filed before the clock runs out. Three actions before end-of-week: (a) pull every entry from April 2025 forward with an IEEPA Chapter 99 secondary code and bucket it: 0–80 days from liquidation, 80–180 days, >180 days; (b) file CAPE on bucket one this week; (c) file §1514 protective protests on bucket two before the 180th day. For a $5M apparel importer with ~$750K of IEEPA exposure, the difference between getting it back in 90 days versus an open-ended Phase 2 is a working-capital event.

The go-live week.

This week was mostly digestion, with one decisive move: CBP confirmed Monday’s CAPE Phase 1 launch. Below — what moved, what didn’t, and the three weeks of catalysts ahead.

CAPE Phase 1 launches Monday Live 8:00 AM ET

CBP confirmed the go-live via CSMS #68340863 (April 13), following CSMS #68315804 (April 10).12 Filers submit a CAPE Declaration as a CSV through a new CAPE tab in the ACE Portal, up to 9,999 entries per declaration. Refunds disburse ACH-only, generally 60–90 days after declaration acceptance (CBP’s March 31 court filing projected 45 days).34 Prerequisites: active ACE Portal account with Importer / Organizational Broker / Filer sub-accounts, and separate ACH refund enrollment (distinct from the ACH duty-payment account).37

56,497 importers were ACH-enrolled as of April 9, covering roughly 82% of affected entries by value.1 Phase 1 is expected to cover ~63% of affected entries. The remaining ~37% — reconciliation (type 09), drawback (47), USMCA deferral (08), TIB (23), manually filed entries, AD/CVD pending Commerce instructions, and entries with open protests — land in Phase 2, no timeline published.34

What narrows the window: Phase 1 scope in one line

Covered: unliquidated entries · entries liquidated ≤80 days before declaration · Suspended / Extended / Under Review · warehouse entries and withdrawals. Excluded (Phase 2, no timeline): type 09 (reconciliation) · type 47 (drawback) · type 08 (USMCA duty deferral) · type 23 (TIB) · AD/CVD pending Commerce instructions · manually filed · entries with open protests.

The PSC pathway is dead for IEEPA refunds PSC denied

CBP has instructed filers that Post Summary Corrections will not be accepted for IEEPA refunds on unliquidated entries — everything goes through CAPE.56 Centers of Excellence are reportedly denying PSCs filed for this purpose. Anyone whose broker filed a PSC expecting a refund has an immediate problem: pull the PSC and refile via CAPE once Phase 1 is live.

CIT lead case switched April 7 Jun 6 appeal clock

Atmus Filtration v. United States was voluntarily dismissed April 7. Euro-Notions Florida, Inc. v. United States (Case No. 25-00595) is now the test vehicle. Judge Eaton reissued the refund order there, which moved the government’s appeal clock to June 6, 2026 (from early May under Atmus).58 An appeal would likely stay CAPE execution. The first real stress test for this whole system arrives in roughly seven weeks.

April 14 CIT status conference. CBP filed a progress declaration: CAPE Claim Portal 95% ready, Mass Processing 85%, Review/Reliquidation 90%, Refund 90%. Judge Eaton’s April 14 order was confirmatory; no new substantive scope changes.5

Section 301 structural-excess-capacity comment period closed Apr 15 Hearings May 5

USTR’s “structural excess capacity and forced labor” investigation covers 16 economies — China, Vietnam, Bangladesh, Cambodia, India, Mexico, among others.9 Hearings begin May 5; outcomes expected late July. No new duties yet, but every apparel and FBA sourcing country is in scope. If you missed the comment window, the next leverage point is monitoring the May hearings and trade-press coverage to model exposure on Q4 sourcing.

Section 232 — digestion week No new FR action

No new Federal Register action this week on the April 6 metals restructuring. The regime stands: full customs value taxed (metal-content carve-out gone), tiered 50% primary / 25% derivative, 247 HTS codes removed from scope via Annex II, UK-only reduced rate (25%/15% conditional on ≥95% UK melt-and-pour for steel or smelt-and-cast for aluminum).101112 All other countries — including EU, Japan, Korea, Brazil, Canada, Mexico — at baseline 50%/25%. Prior country quotas (Korea/Brazil steel, Argentina aluminum, UK/EU/Japan TRQs) all terminated.

No new HTS Chapter 61/62/63 Federal Register action Quiet

Apparel-specific Federal Register activity was light the week of Apr 11–18. The material move — for every apparel importer who paid IEEPA country-specific duties on entries from China, Vietnam, Cambodia, or Bangladesh in the IEEPA window — is the CAPE refund claim filing on Monday, April 20. See chapter I below.

I. Category · Apparel & Textiles

Apparel’s CAPE week.

Apparel importers carry an outsized share of the $175B IEEPA refund pool. File on day one. Then queue the §1514 protests on anything outside Phase 1’s 80-day window — the move brokers will not flag reactively.

What changed this week

Apparel-specific Federal Register activity was light April 11–18. The material move is that every apparel importer who paid IEEPA country-specific duties on entries from China, Vietnam, Cambodia, or Bangladesh in the IEEPA window has a refund claim filing on Monday, April 20. The USTR structural-excess-capacity investigation that closed April 15 puts every major apparel sourcing country on notice — hearings begin May 5.

The current stack: MFN + Section 301 (China only) + 10% §122 baseline (150-day cap — sunsets ~July 24 absent Congressional extension). If §122 sunsets, Vietnam T-shirts revert to ~16.5% and Q4 sourcing math changes materially. Book summer orders with this cliff in mind.

Section 232 does not apply to apparel directly. Apparel with metal trim or hardware may be caught by the April 6 derivative expansion if metal content is substantial — technical outerwear with aluminum/steel components should audit.

The play — fiber-content reclassification (6202)

The women’s outerwear heading 6202 is structured by shell fiber content and the duty rate moves materially across subheadings:2831

SubheadingShell fiberMFN base rate
6202.11Wool or fine animal hair41¢/kg + 16.3%
6202.12Cotton8.9%
6202.13Man-made fibers (MMF)27.7%
6202.19Other textile materialsRate varies

The delta between 6202.13 (MMF) and 6202.12 (cotton) is ~18.8 percentage points of MFN alone. If an outerwear construction is currently classified under 6202.13 because the shell is >50% polyester/nylon, shifting to ≥50% cotton blend (or introducing a cotton outer layer) drops the classification to 6202.12 and strips 18.8 points off the MFN. On $100K imported under that HTS, savings are ~$18,800 per cycle.

The break-even math most brokers won’t walk you through.

Fabric cost premium for 50/50 cotton/poly shell vs. 100% poly is typically $0.40–$1.20/yd depending on weight. At ~2 yards per garment and $35 wholesale, the premium on 10,000 units is $8K–$24K. Duty saving on the same run at $100K landed value is $18,800. Break-even sits between 10,000 and 22,000 units; below, savings get absorbed; above, they clear the fabric premium.

This is a defensible classification move, not a reclassification gimmick. CBP Form 177 binding rulings on fiber-content shell classification are well-established — pull a few on CROSS to confirm scope before committing.32

Caveat: we have not verified this play against a specific brand’s product spec. Framework is sound; the fabric-premium and break-even assumptions should be stress-tested against supplier quotes before acting.

The call on apparel: CAPE refunds + the 6202 fiber-content play are both money already on the table. The refund is the bigger single number; the reclassification compounds every future cycle.
II. Category · Consumer electronics & small FBA goods

The §232 derivative trap.

Most operators read §232 as “metals.” The April 6 restructuring quietly pulled wired goods, small-appliance housings, and anything with substantial steel or aluminum content under a 25%-on-full-customs-value duty. If you sell on Amazon with Chinese sourcing, this is the sleeper story of 2026.

Reader:  Amazon FBA sellers and small ecommerce brands, $500K–$10M revenue, dominantly China-sourced with Vietnam · Mexico · Thailand alternatives

What changed this week

No new Section 301 or HTS Chapter 84/85/95 Federal Register action April 11–18. The material move is CAPE going live on Monday, April 20. For FBA sellers with a China-forward 2025 book, this is the biggest one-time cash event of 2026 — and most customs brokers will not file for you unsolicited. Queue CAPE first, then walk the §232 derivative audit.

De minimis remains closed globally. EO 14324 (July 2025) ended the $800 duty-free exemption; the February 2026 EO preserved the suspension using independent (non-IEEPA) authority, and postal shipments default to the 10% §122 rate.13 Statutory repeal is on the books for 2027. Operational baseline: every import pays duty, full entry process, regardless of per-parcel value.

Current duty stack — China-origin

For Vietnam origin, subtract the §301 column (no direct §301, though CBP circumvention enforcement on China-to-Vietnam transshipment is active). Mexico: USMCA may zero the MFN but §122 still applies; §232 derivative exposure is origin-agnostic.

The §232 derivative trap — the most-missed change

Pre-April 6, a power strip containing $3 of aluminum heat-sink paid §232 only on the $3. Post-April 6, that same power strip — if classified as a covered derivative — pays 25% on the full customs value of the power strip, not the aluminum content. For a $40 landed power strip, that’s $10 of new duty, not $0.75. This hits harder on products where the metal is structural rather than trim: aluminum-housing LED fixtures, steel-body small appliances, wired goods with copper/aluminum conductor.

Audit action: pull your 10-digit HTS codes for 8544, 9405, 8509, 8516, 7323.

Cross-reference against Annex I-A and I-B of the April 2 proclamation. A line that was paying single-digit-effective §232 in March may now be paying 25% on full customs value.

De minimis — dead for your business model

Section 321 is fully suspended globally. Every commercial small-parcel shipment requires formal entry, regardless of value or origin.89 Any inventory model built on China-origin <$800 parcels flowing direct-to-consumer via §321 is no longer viable. Formal entry means: full MFN + §301 + §122 + §232 + any AD/CVD.

The play — First Sale for Export (FSFE)

FSFE is a customs valuation method that lets the importer declare duty on the price paid by the middleman to the factory, not the price paid by the US importer to the middleman. For FBA operators sourcing through Hong Kong trading companies, Alibaba reseller aggregators, or multi-tier agents, the gap between factory price and invoiced price is typically 15–35%. Applying FSFE on a high-MFN-rate SKU (e.g., HTS 6402 footwear at 20%, or §301-hit electronics) drops the duty base by that same 15–35%.

The bar is real: bona fide documentation of the earlier sale, clear title transfer, and arm's-length pricing. Most FBA operators sourcing direct-from-factory don't qualify. But operators using trading companies often do, and most don't realize it — brokers rarely volunteer FSFE because the documentation burden falls on them.

Minimum viable: ≥20% combined MFN+§301, ≥$50K annual landed, trading-company markup.

On a $200K-landed SKU at 35% combined duty and 25% trading markup, FSFE saves ~$17,500 in annual duty, against ~$3K–$8K of documentation effort. Application via CBP's first-sale valuation framework; supported by multiple CBP HQ rulings.35

The call on consumer electronics & FBA: CAPE refunds first, §232 derivative audit second, FSFE scoping third. The derivative audit is the highest-urgency new item — in effect since Apr 6, 2026, and most operators are unaware.
III. Category · Metal components & §232

Metals’ live protest clock.

Policy week was quiet — one meaningful court development. The April 15 depositions order in G&H Diversified is the first-ever discovery into CBP and BIS exclusion denials. SMBs sitting on legacy denials may have a refund path if plaintiff prevails. Meanwhile, the April 6 restructuring remains operative, and the 180-day protest clock is the move brokers won’t flag.

What changed this week

Quiet policy week — no new Federal Register proclamations, BIS inclusion determinations, CBP bulletins, or country quota deals in the April 11–18 window. Digestion of the April 6 restructuring (still operative, details below).

One meaningful court development. April 15: the CIT ordered depositions of CBP and BIS officials in G&H Diversified Manufacturing LP — the first-ever depositions in a Section 232 steel exclusion denial case (covering legacy 2020 denials). Discovery targets the inter-agency exclusion evaluation process.14 Relevant because SMBs sitting on denied legacy exclusions may have a live refund path if plaintiff prevails.

The exclusions portal is gone. The Commerce §232 Exclusions Portal is closed. No new product exclusion requests accepted since February 10, 2025. What replaced it: the “inclusions” process, which runs in the opposite direction — domestic US producers petition to add derivative HTS codes to §232 scope. Importers and foreign producers have no standing.15 Next window: July 1–14, 2026 (auto parts), Docket ITA-2025-0040.

Prior country-specific TRQs (EU, UK, Japan, South Korea) are eliminated under the new regime. Country-rotation playbooks are dead plays.717

The duty-base trap

Under the prior regime, a $100 steel derivative containing $20 of covered steel paid 50% × $20 = $10 of §232. Under the new regime, that same product pays 25% × $100 = $25 — a 2.5× increase on an identical article despite the nominal rate moving down from 50% to 25%.67

Real examples:

A precision-machined steel bracket ($50 landed, $15 steel content) was paying $7.50 of §232; now pays $12.50. A forged aluminum housing ($200 landed, $60 aluminum content) was paying $30; now pays $50. The same is true for any Ch. 73 or covered Ch. 76 HTS.

The play — US-melted-and-poured sourcing

The ≥95% US melted-and-poured carve-out (10% rate, vs. 50%) is the largest structural arbitrage the new regime opens.7 For manufacturers with overseas machining or fabrication capacity, it is now economic to: source raw steel or aluminum from a US mill, ship to overseas fabrication, and re-import the finished component. Import pays 10% §232 — the US origin of the metal governs, not the country of fabrication. Documentation bar: mill test reports (MTRs) must establish US melt-and-pour with ≥95% metal content.

The saving: $600K/yr on a $4M Ch. 73 fastener/forging line.

Against one-time fabrication requalification and MTR-tracking system costs. This is not a loophole. It is an explicit policy tool of the April 2 proclamation; the administration’s stated intent is to reroute demand toward US primary-metals producers. The manufacturers who move first lock in the lowest-cost US mill slots.

The call on metals: The US melt-and-pour arbitrage is the only structural saving offered by the April 2 proclamation. It takes 90–180 days to operationalize (MTR tracking, mill qualification, entry-level procedural change). The cost of being last in line is a full step up the duty ladder.
