Sunrise Consumer Electronics: LandedFees caught a $450,651 Section 301 forced-labor underpayment on VN-origin laptops before liquidation

The shipment

On 2026-08-14, a mid-market importer of consumer electronics filed a CBP 7501 entry for 5,000 units of consumer laptops (HS 8471.30.01) with a declared customs value of $3,600,000. The commercial invoice named a Mexican maquiladora as the manufacturer and the broker filed a USMCA preference claim. Under USMCA the shipment attracted 0 percent duty and the Section 301 forced-labor overlay was suppressed.

Total declared duty on the entry: $0. Total landed cost (broker basis): $3,622,675.00.

What the LandedFees audit engine detected

The audit engine cross-checked the country-of-origin declaration against three data points:

1. The supplier's HS-code x manufacturer country history from prior 7501 filings.
2. The vessel routing on the master bill of lading (loading port Ho Chi Minh, transshipment call Manzanillo).
3. The subassembly-level bill of materials attached to the packing list, which identified Vietnamese-origin display assemblies as the dominant regional-value component.

The tariff-shift analysis under USMCA Chapter 4 Article 4.2 for HS 8471.30 requires either a change from any other chapter or an RVC of at least 60 percent under transaction value. The Mexican operation performed final assembly only, contributing less than 15 percent RVC. The shipment did not qualify. Actual country of origin under 19 CFR 102.11 general rules: Vietnam.

Vietnam-origin HS 8471.30.01 falls within the Section 301 forced-labor overlay (Chapter 99 heading 9903.05.20 through 9903.06.19, effective 2026-07-24) at 12.5 percent ad valorem.

Penalty exposure if not caught

Under 19 USC 1592(c)(1), an omitted material fact in the entry summary (here, the misdeclared country of origin) is treated as a negligent violation. Penalties for negligence are the lesser of the domestic value of the merchandise or two times the loss of duty. Loss of duty here is $450,000. The two times cap: $900,000. Plus interest under 19 USC 1520(a)(4) at the CBP prime + 3 percent rate from entry date to liquidation.

Had the entry liquidated without correction and CBP later challenged the USMCA claim under a Focused Assessment or a Section 232 pre-liquidation review, the importer's exposure was: $450,000 in duty owed plus up to $450,000 in gross negligence penalty plus interest running from 2026-08-14. Total mid-case exposure: approximately $1.1M against a shipment with $3.6M in goods value.

Filing path

The importer filed a Post Summary Correction under 19 CFR 141.111 through the CAPE Phase 2 module in ACE on 2026-08-15, day 1 of the 314-day window. The PSC package included:

• Amended entry summary declaring Vietnam as country of origin.
• Withdrawal of the USMCA preference claim.
• Application of the Chapter 99 9903.05.20 heading for the Section 301 forced-labor overlay at 12.5 percent.
• Supplier country-of-origin affidavit and bill-of-materials attestation from the Mexican maquiladora confirming the Vietnamese subassembly source.
• Voluntary tender of the $450,651.50 delta duty and fees.

Voluntary tender before CBP initiates enforcement typically extinguishes 1592 penalty exposure under 19 CFR 162.74. The importer paid the amended duty and closed the exposure at cost basis with no penalty assessment.

Timeline

• 2026-08-14 entry summary filed.
• 2026-08-15 LandedFees audit engine surfaced the origin mismatch and quantified the $450,651.50 delta.
• 2026-08-15 broker filed CAPE PSC with amended entry summary and voluntary duty tender.
• Expected liquidation: 2027-06-25 (day 314 from entry summary). PSC acceptance and refund/tender reconciliation typically 60 to 120 days from PSC file.

The takeaway

Post-2026-07-24 the Section 301 forced-labor overlay attaches at 12.5 percent to nearly every non-USMCA-qualifying origin for the covered chapters. USMCA preference claims that were survivable under Section 122 (before the sunset) are now the single highest-audit-risk line item on a CBP 7501, because the delta between the overlay-exempt USMCA rate and the overlay-inclusive non-USMCA rate is 12.5 percentage points. On a $3.6M shipment that is $450,000 per entry.

The LandedFees audit engine runs the same origin cross-check on every entry the importer submits. On a $3.6M consolidation the marginal cost of the audit is under one percent of the delta it catches.
