6. Thinking Outside the US: How Vietnam Drives Bulk Production and Maximizes Profits

For brands that require large volumes, from hundreds of thousands to millions of pieces, even a small cost saving per item can translate into significant reductions in overall expenses. This economic advantage is a primary reason why many brands, particularly those looking to manufacture overseas in Asia, favor destinations like Vietnam.

Vietnam offers a substantial labor cost benefit, with regional minimum wages significantly lower than those for skilled sewing operators in the U.S. This directly translates into a considerable reduction in the Cost of Goods Sold (COGS) for labor-intensive garments such as underwear. Moreover, Vietnam's strategic geographic location near major Asian textile hubs allows for faster and more efficient sourcing, characterized by short fabric lead times and ready access to large-scale vertical mills.

Despite the introduction of reciprocal tariffs, Vietnamese apparel generally maintains a landed cost that is considerably lower than U.S. domestic production, which often contends with high operational overheads. Vietnam's industrial clusters are capable of scaling production from 5,000 to over 50,000 units per order while maintaining consistent quality, a capacity often unmatched by many U.S. garment factories that operate as smaller, boutique shops. The country's robust apparel export turnover and its position as a leading apparel exporter to the U.S. highlight its stability as a long-term manufacturing alternative for American brands looking to diversify their supply chains. Thygesen Textile Vietnam is a reliable clothing manufacturer for US brands, demonstrating this capacity.
