Vietnam’s tuna on the brink of 0% tariffs in the U.S: Breakthrough potential but significant challenges remain

A notable highlight in the Joint Statement is the identification of products listed in Annex III of U.S. Executive Order No.14346 (dated September 5, 2025), which aims to “adjust potential tariffs for like-minded partners” as eligible for a reciprocal tariff rate of 0%.

Among the product groups likely to benefit from this tariff adjustment are fresh or chilled albacore tuna (HS03023100); frozen tuna loins and fillets (HS03048700) and prepared or preserved tuna and skipjack, not in airtight containers, not in oil, in bulk or in immediate containers exceeding 6.8 kg (HS 16041440).

If these product categories are officially granted duty-free status, it would deliver a significant boost to the competitiveness of Vietnamese tuna in the U.S. market - one of the world’s largest tuna-consuming markets. In recent years, the United States has consistently been Vietnam’s top import market for tuna. However, Vietnamese exporters have faced disadvantages due to high logistics costs and import duties. Reducing the tariff to 0% would enable Vietnamese products to compete more effectively against supplies from Ecuador, Thailand and the Philippines - especially in the high-value frozen loin/fillet segment and products destined for the U.S. foodservice sector.

However, the opportunity is far from guaranteed. The detailed list of products eligible for the preferential tariff has not yet been officially published by the U.S side. Accompanying conditions - strict rules of origin, traceability requirements and sustainability standards - will pose substantial barriers for many Vietnamese enterprises. Over the past several years, Vietnam’s tuna industry has faced increasingly stringent requirements from the U.S. and other major markets regarding illegal, unreported and unregulated (IUU) fishing; marine mammal protection (under the MMPA); supply-chain transparency and Marine Stewardship Council (MSC) certifications. Companies that fail to meet these standards will be unable to capitalize on the tariff advantage, even if their products are included in the preferential list.

Furthermore, trade conditions between the two countries remain uncertain, as the U.S. currently applying a 20% reciprocal tariff on many Vietnamese goods this year. The 0% rate is highly likely to be applied selectively, prioritizing items that clearly demonstrate “fair reciprocity” and full transparency of origin.

Against this backdrop, Vietnamese tuna exporters are aggressively shifting toward value-added products such as loins, fillets and large-pack processed tuna. This transition is seen as appropriate - not only to improve profit margins but also to meet the growing demand for green, sustainable products in the U.S. market.

Looking ahead 6-18 months, if the 0% tariff is indeed applied to the HS codes mentioned, Vietnam’s tuna exports to the U.S could resume growth after the stagnation experienced in 2024-2025. At the same time, sustained investment in traceability systems, standardized processing practices and building a national brand for Vietnamese tuna will determine whether the country can capitalize on this tariff-opening opportunity.

The opportunity is substantial but it will not automatically translate into benefits. Without standardized supply chains, transparent raw-material sourcing, and strict IUU compliance, the 0% tariff may remain merely a theoretical advantage.

Vietnam’s tuna industry now stands at a critical juncture - where tariff rates are no longer the sole determining factor. Instead, adaptability, transparency and sustainable product value will shape its success in the U.S. market in the years ahead.
