Why Source Aluminum Extrusions from Vietnam?
Vietnam's aluminum extrusion industry has grown rapidly over the past decade — driven by investment in modern press technology, integrated anodizing and powder coating lines, and a manufacturing workforce skilled in complex profile design. What was once a niche capability has matured into a full-service extrusion ecosystem covering profiles from simple angles and channels to complex multi-void hollow sections.
For global buyers, Vietnam offers a compelling combination: lower ex-factory costs than China, proximity to Southeast Asian assembly hubs, coverage under 16+ Free Trade Agreements including CPTPP, RCEP, and the EVFTA, and — critically for US buyers — $0 Section 301 tariff exposure. Chinese aluminum extrusions face 25% Section 301 tariffs plus anti-dumping duties as high as 374%.
The challenge has always been factory verification. DEWIN solves that. We've physically visited and audited every extrusion factory in our network under the 50-point Dolphin framework — verifying press capacity, die shop capability, material traceability, surface finishing quality, and QC documentation. You see real photos, real audit scores, and real capabilities before you commit.
Vietnam Aluminum Extrusion: Indicative Pricing
Indicative pricing from our audited extrusion network. Prices include extrusion, cutting to length, and standard surface finish at stated quantities.
| Profile Example | China Ex-Factory | Vietnam (DEWIN) | Vietnam vs China |
|---|---|---|---|
| T-slot frame profile (6063-T5, 1,000kg) | $2.90–3.60/kg | $2.80–3.40/kg | ~10–15% lower |
| Heatsink profile (6061-T6, 500kg) | $3.40–4.50/kg | $3.20–4.20/kg | ~10–15% lower |
| Window frame profile (6063-T5, anodized, 2,000kg) | $3.10–3.90/kg | $2.90–3.60/kg | ~10–15% lower |
| Structural channel (6082-T6, 3,000kg) | $2.70–3.40/kg | $2.60–3.20/kg | ~10–15% lower |
Prices are per-kg at listed quantities, excluding die costs. US buyers also benefit from $0 Section 301 tariff vs 25%+ on Chinese-origin extrusions. Request an exact quote for your profile.
