Section 321 of the Tariff Act of 1930 allows CBP to release shipments valued at $800 or less on a duty-free, entry-free basis — one shipment per person per day. For direct-to-consumer e-commerce operations routing through Port Newark and Carteret warehouses, Section 321 can eliminate substantial duty exposure. For high-volume B2B importers, the misapplication of Section 321 creates CBP enforcement risk that directly affects financing availability.


What Section 321 Actually Covers

  • Eligible shipments: Articles imported by one person on one day, fair retail value not exceeding $800. No formal entry required. No duties, taxes, or fees assessed.
  • Frequency restriction: The $800 threshold applies per person per day. A single buyer cannot receive multiple Section 321 shipments from the same or different importers on the same day that, in aggregate, exceed $800.
  • Excluded merchandise: Section 301 tariffs on Chinese-origin goods (verify current CBP guidance as this exclusion has been subject to regulatory change), antidumping duties (ADD), countervailing duties (CVD), and quota-restricted merchandise cannot benefit from Section 321.

2025 enforcement note: Regulations governing Section 321 eligibility for Chinese-origin goods have been subject to change. Verify current CBP guidance with a licensed customs broker before structuring any Section 321 program.


CBP Enforcement at Port Newark: What's Changed

1. Manifest review for structured shipments: CBP algorithms now flag import manifests showing patterns consistent with artificially divided shipments — multiple consignees at the same address, identical SKU descriptions below $800, high-frequency small-value entries from single suppliers.

2. Post-importation audits: CBP has begun conducting post-importation audits on importers with high Section 321 entry volumes, reviewing whether the "one person per day" restriction is being accurately applied.

3. Bonded warehouse scrutiny: Carteret-area bonded warehouse operators have received CBP audit requests related to Section 321 programs.

Enforcement consequence: A finding of Section 321 abuse can result in formal entry requirements being imposed retroactively, penalty assessments, and importer suspension from the ACE system — all of which directly prevent access to institutional trade financing.


Capital Strategy: When Section 321 Helps and When It Hurts

Legitimate Section 321 Use Cases for NJ Importers

  • Direct-to-consumer (DTC) brands using Port Newark/Carteret for national distribution of sub-$800 orders
  • B2B importers with occasional small-value test orders below $800
  • Return-to-origin shipments of sample merchandise

Capital benefit: Eliminating formal entry requirements reduces customs broker fees by $85–$200 per entry and eliminates duty exposure. On a 1,000-unit DTC operation with $750 average order value, that is $85,000–$200,000 in annual savings.

When Section 321 Creates Financing Risk

If your Section 321 program is structured around splitting shipments to avoid duties on higher-value merchandise, CBP enforcement exposure creates contingent liability that institutional lenders will flag in underwriting. Sentinel's pre-financing compliance review includes a Section 321 usage assessment for importers with DTC components.


Clearance Flow: Section 321 vs. Formal Entry at Port Newark

Section 321 clearance flow: Manifest submission → CBP automated release (ACE) → Carrier release → Dray to Carteret → No duty payment

Formal entry flow: ISF filing (24h pre-load) → Vessel arrival → Entry filing (CF-7501) → Duty payment → CBP release → Dray to Carteret

Capital timing difference: Section 321 eliminates the duty payment step — which for a $1M shipment at 25% duty represents $250,000 in working capital that does not need to be deployed at port. Properly structured Section 321 programs are a genuine working capital strategy.
