Cross-Border DG Compliance —
One Shipment. Two Regulatory Systems.
A dangerous goods shipment crossing the Mexico-US border must comply with both SCT and DOT regulations simultaneously — and they don't always agree. We resolve the conflicts before your cargo reaches the port of entry.
Request a ConsultationWhere Cross-Border DG Shipments Fail
Cross-border dangerous goods failures don't happen at the shipper's facility — they happen at the border, when a CBP or SCT inspector finds a documentation mismatch that stops the shipment.
SCT-Compliant but DOT Non-Compliant
Packaging and labelling that fully complies with Mexican SCT regulations may still fail DOT 49 CFR requirements at US entry. The two frameworks are not equivalent.
Documentation Format Conflicts
Emergency response information, placarding requirements, and shipper certification formats differ between SCT and DOT. A document valid for Mexico may be rejected at the US border.
Packaging Acceptance at Destination
UN certification recognized under SCT may not be accepted under DOT for certain material classes. Cross-border shipments must be packaged to the more restrictive standard.
Multimodal Reclassification
A ground shipment that transitions to air or ocean at the border requires reclassification under IATA DGR or IMDG rules — which may differ from the ground-transport classification used in Mexico.
What Our Cross-Border DG Service Covers
We prepare your dangerous goods shipment to meet both Mexican SCT and US DOT requirements simultaneously — with documentation, packaging review, and border-crossing coordination.
Dual-Regulation Classification Review
UN number, PSN, hazard class, and packing group verified under both SCT and DOT 49 CFR to identify discrepancies before shipment preparation.
Cross-Border Documentation Preparation
Shipping papers, emergency response documentation, and shipper's certification prepared to satisfy both Mexican and US regulatory requirements.
Packaging Compatibility Assessment
Packaging reviewed against both SCT and DOT requirements. Where they conflict, we identify the more restrictive standard and recommend compliant alternatives.
Port of Entry Compliance Mapping
For regular routes, we document the specific compliance requirements at each port of entry — so your team has a route-specific checklist, not a general guideline.
Air & Ocean Mode Transition Support
When ground shipments transition to air or ocean at the border, we handle the modal reclassification and documentation update under IATA DGR or IMDG.
Cross-Border Expertise That Keeps Cargo Moving
We have supported Mexico-US and Mexico-Canada dangerous goods shipments across pharmaceutical, chemical, and industrial sectors — learning where each framework creates friction.
Both Frameworks, One Team
Our specialists are certified in both SCT and DOT 49 CFR requirements — no hand-off between a Mexican expert and a US expert halfway through your shipment.
Route-Level Compliance Detail
We work with specific ports of entry, not abstract regulatory frameworks. Our guidance reflects what actually happens at the border, not just what the regulation says.
Regulatory Change Tracking
Annual DOT 49 CFR amendments and SCT regulatory updates are monitored and incorporated into our compliance guidance as they take effect.
Pre-Departure Compliance Review
We offer a final compliance check before any cross-border dangerous goods shipment departs — the last opportunity to catch a documentation conflict before it becomes a border hold.
