At 12:01 a.m. Washington time on July 24, the Section 122 surcharge that had added 10% to most Vietnamese goods since February hit its 150-day limit and expired. A Section 301 duty took effect at the exact same time. The legal basis changed with it: Section 122 rested on a balance-of-payments rationale a US court had ruled unlawful in May, though the Federal Circuit stayed the decision and collection continued.

The new duty comes out of forced-labor investigations USTR opened against 60 economies in March. Two rates apply: 10% for economies that have adopted, committed to, or partly operate a ban on forced-labor imports, and 12.5% for the rest. Vietnam is one of 38 economies at the flat 12.5% rate, a group spanning China and Russia to Australia and Norway; regionally, Thailand, the Philippines, and Singapore drew 12.5% too.

The bite is in who got 10%: India, Indonesia, Cambodia, Bangladesh, Malaysia, Pakistan, and Sri Lanka -- Vietnam's competitors for US apparel, footwear, seafood, and farm orders. Four of them (Bangladesh, Cambodia, Indonesia, Malaysia) also received textile and apparel quotas that let a set volume enter free of the new duty, tied to their use of US cotton. Vietnam got no quota and no country-specific exemption list, only the universal one every covered economy receives. In the sectors where these countries chase the same buyer, the wedge runs 2.5 points, wider in textiles.

Vietnam had moved to close that gap. On July 22 it issued Decree 292, banning imports of goods made with forced labor -- but not in force until September 5. On July 23, when USTR finalized, Vietnam had promulgated a prohibition, not imposed one. After USTR's June 5 proposed action, six economies -- Cambodia, Guatemala, Honduras, India, Sri Lanka, and Trinidad and Tobago -- enacted bans and were moved to 10%, with no hard cutoff. Vietnam acted the day before the final determination and stayed at 12.5%. That documented asymmetry is the opening Hanoi will press.

Even so, the Ministry of Industry and Trade puts the covered share near 37% of export value to the US after exemptions. Smartphones, laptops, and semiconductors, Vietnam's largest export category, are broadly exempt across all 60 economies, so the duty lands on apparel, footwear, seafood, and agriculture. Goods already under Section 232 tariffs are excluded outright. MoIT has told exporters to tighten origin control and avoid transshipment or repackaging to claim Vietnamese origin. Vietnam had issued the ban the lower rate required, forty-four days too late.
