Customs API Integration & Compliance for Freight Forwarders & 3PLs in United States

Why freight forwarders & 3pls in United States choose Belli for customs API

Belli rebuilt customs API from first principles for freight forwarders & 3pls in United States — not as a bolt-on to a legacy core. Customs compliance is increasingly complex. Belli provides direct API integration with customs authorities in 50+ countries. North American air cargo is dominated by the US ACAS/ACMS security regime and sophisticated customs requirements.

Operators routing through Chicago O'Hare (ORD) and Louisville (SDF) — carriers in the class of WestJet Cargo, Kalitta Air — face the same pressure: more volume, tighter slots, and zero tolerance for a load plan that leaves revenue on the ramp. Belli's customs API targets a measurable outcome — 50+ countries automated — and goes live in 10 days for teams operating in United States, not 12–18 months. United States deployments inherit the same SLA.

The operational reality in United States

Here is what actually breaks for freight forwarders & 3pls in United States.

• No single view of shipment status once cargo leaves the warehouse — compounded in United States by US ACAS mandatory pre-departure filing
• Booking air cargo across airlines through fragmented portals and email — compounded in United States by canada PACT pre-load targeting requirements
• Re-keying data between forwarding software and airline EDI
• United States-specific: ACE customs system. ACAS pre-departure filing. TSA screening compliance.

What changes with Belli

Belli replaces that with a single platform tuned for United States's requirements:

• Buy/sell rate management with real-time margin visibility
• Automated eAWB and HAWB creation with IATA ONE Record transmission
• End-to-end shipment milestone tracking in a single dashboard

Before Belli: Manual customs filing creates delays and compliance risks. Each country managed separately. After Belli: Automated filing across 50+ countries from a single system. Zero PLACI compliance failures.

How Belli's Customs API works in United States

Belli's customs API runs as one connected workflow, configured for United States from day one.

In practice, that means automated hold/release response management, pre-arrival cargo information filing (PLACI), and US ACAS/ACMS integration. Belli also covers EU ICS2 full compliance against United States's specific constraints. Every step is auditable, and changes deploy continuously rather than in quarterly batches.

Built for United States's requirements

Running cargo in United States means living inside its rules, not around them. North American air cargo is dominated by the US ACAS/ACMS security regime and sophisticated customs requirements.

That shows up in the details: e-commerce fulfillment cargo growth; USMCA trade agreement customs facilitation; and US ACAS mandatory pre-departure filing. United States adds its own layer — ACE customs system. ACAS pre-departure filing. TSA screening compliance. Carriers such as WestJet Cargo, Kalitta Air, ABX Air operate against exactly these conditions.

Going live in 10 days in United States

Go-live is measured in days, and the date is contractual. The first days are spent migrating live bookings, tariffs, and message flows. By go-live your operators are trained on the same workflows they already run in United States. Post-launch, changes ship continuously rather than waiting for a quarterly release.

The bottom line for Freight Forwarders & 3PLs in United States

The decision comes down to one question for United States operators. Each delayed integration is margin that never shows up on the P&L. 50+ countries automated is the outcome Belli is engineered to deliver. Carriers like WestJet Cargo, Kalitta Air, ABX Air already operate at this standard. The next step is a working demo, not a six-week sales cycle.
