• Air cargo moves more than 35 percent of global trade by value, yet significant compliance gaps remain across customs classification, pharmaceutical handling, dangerous goods declarations, cargo identity and live animal transport.
• The article argues that these weaknesses are structural rather than isolated, exposing carriers and forwarders to safety, regulatory and reputational risks.
• Stronger data use, pre-acceptance controls, shipper accountability and real-time monitoring will be essential if the industry is to address them before the next preventable incident.

Air cargo moves more than 35 percent of global trade by value. Yet beneath the industry’s impressive efficiency metrics lies a set of compliance vulnerabilities that carriers, forwarders and regulators have collectively chosen to manage rather than solve.

After nearly two decades working across Singapore Airlines, DHL Global Forwarding, DB Schenker and Turkish Airlines Cargo, I have observed these gaps not as theoretical risks, but as operational realities that surface daily across cargo networks.

Here are five that demand urgent attention.

1. HTS misclassification – the invisible revenue and safety leak

Harmonised Tariff Schedule misclassification is widely understood as a customs compliance issue. What is less frequently discussed is its direct safety dimension in air cargo.

When shippers misclassify goods to reduce duty exposure, they frequently obscure the true nature of their cargo. A lithium battery shipment misclassified as electronic accessories. A chemical compound declared as industrial equipment. The customs violation and the safety violation are the same act.

CBP enforcement data consistently show misclassification as one of the highest-volume violation categories at US ports of entry. In air cargo specifically, where screening windows are narrow and dwell times short, the consequences of undeclared hazardous content are severe.

The industry has invested heavily in screening technology. It has invested far less in the accuracy of upstream declarations that makes screening meaningful.

2. Pharmaceutical cold chain – the dwell time nobody measures

The air cargo industry has made significant progress on temperature-controlled infrastructure. Purpose-built cool-chain facilities, GDP-compliant handling procedures and real-time monitoring during flight have become standard at major hubs.

What remains largely unmonitored is ground-transfer dwell time, the period between aircraft offload and handover to temperature-controlled storage.

In my research across three major hub airports, average dwell times during this window exceeded 45 minutes. For temperature-sensitive biologics and vaccines, this is not an acceptable grey zone. It is a systematic failure point that existing compliance frameworks do not adequately address.

The pharmaceutical supply chain has a chain-of-custody problem hiding in plain sight, and it sits squarely within air cargo’s operational responsibility.

3. Dangerous goods misdeclaration, the self-declaration gap

IATA’s Dangerous Goods Regulations represent one of aviation’s most comprehensive safety frameworks. They also rely fundamentally on shipper self-declaration, a mechanism that assumes honesty, accurate knowledge and consistent application across millions of annual shipments.

The assumption does not hold.

Undeclared and misdeclared dangerous goods remain a leading contributory factor in aviation safety incidents. The gap between what shippers declare and what aircraft actually carry is not a compliance anomaly, it is a structural feature of a system that places the highest-risk decision at its most vulnerable point.

Stronger pre-acceptance screening, shipper education and accountability frameworks are not optional enhancements. They are overdue corrections.

4. Cargo identity fraud, who is actually shipping?

Known shipper programmes and regulated agent frameworks were designed to establish cargo provenance. They work well when the entities in the supply chain are who they claim to be.

Cargo identity fraud — the misrepresentation of shipper identity to exploit trusted status — is a growing and underreported vulnerability. It exploits the trust-based architecture of air cargo security rather than attempting to defeat its technical controls.

The industry’s response has largely focused on document verification. The harder problem is behavioural pattern recognition — identifying shipments whose declared origin, routing and content profile do not cohere.

This requires a different kind of analytical attention from that provided by traditional compliance screening.

5. Live animal welfare – regulatory exposure in motion

Air cargo carries millions of live animals annually, companion animals, livestock, laboratory specimens and endangered species under CITES protection. The regulatory frameworks governing their transport are detailed. Compliance monitoring during transit is not.

Temperature fluctuations, ventilation failures and handling errors involving live animal shipments generate both welfare consequences and significant regulatory and reputational exposure for carriers. Yet real-time welfare monitoring during ground handling and transit remains inconsistently applied across the industry.

As regulatory scrutiny of live animal transport intensifies, particularly in the US and EU, carriers that cannot demonstrate continuous welfare monitoring will find themselves exposed in ways their current compliance documentation does not protect against.

A practitioner’s conclusion

These five gaps share a common characteristic: they are known, they are measurable and they persist because the industry’s incentive structures have not yet made solving them more attractive than managing them.

That calculation is changing. Regulatory enforcement is intensifying. Shipper accountability expectations are rising. The data infrastructure required to address these gaps, if applied with genuine operational intent, now exists.

The question is not whether the industry will close these blind spots. It is whether it will do so proactively or in response to the next preventable incident.
