2. Thinking Outside the US: How Vietnam Drives Bulk Production and Maximizes Profits
Producing underwear at large volumes from hundreds of thousands to millions of pieces means that even saving just $1 per item can translate into significant cost reductions. This is why many brands looking to manufacture overseas, especially in Asia, favor destinations like Vietnam, which, alongside China.
- Labor Cost Advantage: Vietnam offers a substantial labor cost benefit, with regional minimum wages ranging from $0.70 to $1.00 per hour (Decree 293/2025/ND-CP), compared to $15-$22 per hour for skilled sewing operators in the U.S. (U.S. Bureau of Labor Statistics, 2025/2026). For labor-intensive garments like performance activewear, this translates into a 3-5x reduction in Cost of Goods Sold (COGS).
- Supply Chain Proximity: Vietnam’s geographic closeness to major Asian textile hubs enables faster and more efficient sourcing, with fabric lead times of just 3-7 days and easy access to large-scale vertical mills. In contrast, U.S. manufacturers often face 30-45 day delays and higher logistics costs when importing fabrics from Asia (World Bank Logistics Performance Index; VITAS, 2025).
- Tariff Optimization: Even with the 20% reciprocal tariff introduced in late 2025 (USTR Framework Agreement, 2025), Vietnamese apparel maintains a landed cost 30-50% lower than U.S. domestic production. U.S. factories contend with high operational overheads and expensive local inputs, which are not taxed but significantly increase costs (USITC HTSUS Analysis, 2026).
- Scalability & Industrial Capacity: Vietnam’s industrial clusters can scale production from 5,000 to over 50,000 units per order while maintaining consistent quality (Vinatex, 2025). Meanwhile, most U.S. garment factories operate as micro-factories or boutique shops, limiting their capacity for large-scale, mass-market production (U.S. Fashion Industry Association Benchmarking Study, 2025).
- Political & Trade Stability: Vietnam’s robust $39.6 billion apparel export turnover in 2025 and its emergence as the #1 apparel exporter to the U.S., surpassing China by mid-2025, underlines its position as a stable, long-term manufacturing alternative for American brands seeking to reduce China-related risks (According to Vietnam Customs Department; Fibre2Fashion, 2026).
