A wave of new import tariffs is set to reshape global trade dynamics and significantly raise trade costs for many developing countries, alerts UN Trade and Development (UNCTAD) in a new data-driven analysis, titled “Sparing the vulnerable: The cost of new tariff burdens”.
The vulnerable economies most exposed – including Least Developed Countries and Small Island Developing States – typically account for a tiny share of global trade, yet now face some of the steepest tariff increases.
What’s changing:
- US tariffs may jump to over 25% for 22 developing economies in July 2025, including seven least developed countries.
- Some tariff hikes, particularly on Chinese imports, have exceeded 100%, even after recent adjustments.
- New tariffs apply regardless of existing trade agreements or World Trade Organisation (WTO) rules. This includes countries previously benefiting from preferential terms.
Who’s affected most:
- Least Developed Countries (LDCs) and developing countries in Asia and Oceania face the steepest increases.
- Tariffs on LDCs have already doubled in April and could rise nearly threefold in July – from 16% to 44%.
- For Latin America and the Caribbean, tariff levels have risen over 40 times, from less than 0,5% to 13%.
- Even without China, tariffs on developing countries in Asia and Oceania have already risen to 13% and could further increase to 24%.
- Key sectors like agriculture and textiles, crucial for many vulnerable economies, are especially exposed.
Why this matters now:
On 2 April 2025, the US imposed a universal 10% tariff on all imports. Additional country-specific tariffs are set to take effect in early July, following the expiration of a 90-day pause.
These measures will raise the cost of market access – even for countries with minimal contribution to global trade imbalances.
Vulnerable economies could see export prospects shrink, despite these economies representing only 0.3% of the US trade deficit.
