WAlthough the world’s attention today is focused on the return of protectionist tariffs, a more subtle and costly shift is undermining the global trade landscape. According to the latest World Trade Update from the United Nations on Trade and Development (UNCTAD), friction in modern trade no longer exists just at customs offices, but within complex and often opaque non-tariff measures.
Modernization – Invisible Barriers: The Costs of Non-Tariff Measures, sees a new regime of “intervention” replacing trade liberalization. This has been driven by ongoing shocks from the Covid-19 pandemic, the war in Ukraine, and increased US tariffs in 2025. The report said this shift sees major economies moving towards “a more distortive use of trade policy to achieve industrial policy objectives, enhance supply chain resilience and address national security concerns”.
For the first time in decades, UNCTAD notes, tariffs are moving upward across the board. In 2025, global export tariffs will rise by 10% for developed countries, 16% for developing countries, and 18% for the world’s least developed countries.
However, even with the resurgence of traditional protectionism, UNCTAD data reveal that non-tariff measures continue to impose higher costs on exports in 88% of all countries.
These measures, ranging from technical product standards to environmental regulations, now dictate the flow of goods more than taxes.
The burden of this transformation is not shared equally. Small developing countries and least developed countries find themselves caught in a “double burden” as they face rising tariffs and astronomical compliance costs. UNCTAD researchers found that least developed countries lose nearly 10% of their exports to G20 markets simply because of their “inability to comply with non-tariff measures compared to other developing countries.” This gap is exacerbated by the lack of local infrastructure, such as accredited laboratories or certification bodies, which forces exporters to ship goods through third countries just to prove they meet international requirements.
The silent treatment
Furthermore, the document highlights the “diplomatic silence” on the part of the world’s poorest countries. While developing countries have recently surpassed developed countries in raising and responding to specific trade concerns in the WTO, the participation of least developed countries remains minimal. This absence suggests that these countries are not yet fully equipped to take advantage of the multilateral system to challenge the very regulations that limit their growth.
The report notes that “despite their high exposure to non-tariff measures, least developed countries remain largely absent from international dialogue,” a factor that significantly hampers their ability to negotiate fairer trade terms.
Even when measures are ostensibly for the public good – such as those to protect health or the environment – their implementation often creates “hidden barriers”.
The report notes that technical non-tariff measures have been on the rise for two decades and are now “three times more frequent than all other trade policy interventions combined.”
These requirements shape who trades and what gets traded, often to the advantage of larger firms that have the financial and technical capacity to navigate the shifting regulatory sands. This creates a market where “compliance capability, not price or quality, becomes the primary competitive advantage.”
Much of this trade friction stems from a lack of transparency. When countries fail to notify the WTO of a change in their regulatory systems, the economic impact is “similar to imposing a 28% tariff.” For small businesses, these hidden costs are often enough to completely exclude them from the global market. UNCTAD notes that improving transparency alone could reduce trade costs associated with these barriers by about 19%, describing this as “low-hanging fruit” for international policy.
The report also highlights the “strategic use of interdependence” in recent trade agreements. In contrast to deals of the past that focused on reducing tariffs, modern agreements have now become “central pillars” to ease regulatory and administrative requirements. For example, recent US trade agreements focus largely on recognizing US standards for vehicles, pharmaceuticals, and agricultural food products. In contrast, the EU’s agreements with India and Mercosur emphasize mutual recognition and alignment with broader international standards.
This difference in organizational strategy creates a fragmented global market. “As major economies harmonize their regulatory frameworks with different blocs, the risk of a bifurcated global trading system increases,” UNCTAD warns. For exporters in developing countries, this means managing multiple sets of incompatible standards, which “significantly increases the cost of diversification” and forces them to choose between major consumer markets rather than serving all of them efficiently.
“Capacity Building for Compliance”
Looking to the future, the most important potential for growth may lie in South-South trade, that is, trade between developing countries, according to UNCTAD. However, this potential is currently limited by poor transparency and lack of regulatory harmonization. In Africa, even a “moderate form of regulatory cooperation” where countries simply harmonize the types of measures they implement can reduce trade costs by 30% to 40%. The implementation of the African Continental Free Trade Area (AfCFTA) is cited as a crucial opportunity to demonstrate that “regulatory convergence is more effective than simply eliminating tariffs in stimulating regional value chains.”
The White Paper concludes with a call to action for the international community to prioritize “building capacity for compliance.”
The report argues that providing technical assistance to least developed countries is not just an act of development assistance, but rather a necessity for maintaining an effective global trading system. Without this support, the “invisible walls” of technical regulation will continue to widen the economic gap between the global North and South.
Ultimately, UNCTAD warns, in the absence of a concerted global effort to strengthen regulatory cooperation and transparency, these invisible walls threaten to “erode the benefits of decades of tariff liberalization.” For the global trading community, the challenge is no longer just about the entry price, but about the increasingly complex rules of the game. The “unprecedented rise in policy-driven trade costs” points to a future where trade is defined less by open borders and more by the ability to navigate mandates, certifications and geopolitical alliances. As the report says: “The era of simple trade is over; the era of complex compliance has begun.”
