Vietnam vs China PSF: a buyer's sourcing comparison.

China is the dominant global PSF producer. Most buyers default to it. But "default to China" stopped being the obvious answer around 2018-2019 for a growing slice of buyers — and the case for Vietnam has only strengthened since. Here's a practical comparison, no marketing spin.

The honest head-to-head

1. Price per kg

For the same spec (1.4D x 38mm SD RW, virgin, semi-dull), China is usually $0.05-0.15/kg cheaper at the mill gate. The gap varies with PX-PTA-MEG prices and the size of the order, but China has scale advantages on commodity specs that Vietnam can't fully match.

But raw mill-gate price isn't the only number. Add in the freight, duty, and inland cost, and the gap often shrinks to $0.02-0.05/kg, especially for South and Southeast Asian buyers. We'll come back to that.

2. Lead time

China has more production capacity and more frequent vessel calls. For a standard spec, China can usually deliver in 2-3 weeks from PO. Vietnam is 2-4 weeks for virgin, 4-6 weeks for recycled.

But Vietnam is closer to most South Asian destinations by sea. Total door-to-door is often 1-2 weeks faster from Vietnam to Bangladesh, India, Sri Lanka, and Indonesia than from China. For ASEAN buyers, Vietnam is a domestic play.

3. Minimum order quantity (MOQ)

Chinese suppliers typically want 20-25 MT minimum per spec. Some smaller Chinese mills will do 5 MT for a premium, but it's not the norm. Vietnamese suppliers (especially trading operations like us) routinely accept 5 MT, with sample orders from 1 MT.

For small and mid-size buyers — the segment most underserved by Indorama and Reliance — this difference alone can be the deciding factor.

4. Tariff and trade agreement access

This is the most-overlooked factor and the one that often flips the math. Vietnam has C/O access via:

• ATIGA (Form D) — duty-free or reduced rates to all ASEAN member states (Vietnam, Thailand, Indonesia, Philippines, Malaysia, Singapore, Cambodia, Laos, Myanmar, Brunei)
• EVFTA (Form EUR.1) — preferential tariff treatment to EU markets. Significant reductions on PSF (textile fibers).
• CPTPP / RCEP — Vietnam is a signatory to both. CPTPP gives preferential access to Canada, Mexico, Japan, Australia, New Zealand, Singapore, Malaysia, Vietnam, Brunei, Chile, Peru, UK. RCEP covers ASEAN + China + Japan + Korea + Australia + NZ.

For an Indian buyer importing Vietnamese PSF under ATIGA: zero duty. Same buyer importing Chinese PSF: 10-15% basic customs duty (depending on HS code and whether BCD applies). For a Bangladesh buyer importing Vietnamese PSF under ATIGA: zero or near-zero. From China: similar 5-15% range. The 10% gap often exceeds the mill-gate price gap.

5. GRS / recycled content

China has more GRS-certified production capacity than Vietnam, but the supply is concentrated at large mills. Vietnam has a thinner absolute supply but a more accessible one for small and mid-size buyers. Quality is comparable.

Recycled PSF from both origins is currently ~20% above virgin equivalent. The price gap is similar.

6. Supply reliability

China has more capacity, more producers, more redundancy. If one mill fails, you can find another. Vietnam has fewer producers (maybe 15-20 significant PSF producers vs China's 100+). If your Vietnamese supplier has an issue, switching cost is higher.

This matters less if you have a reliable trading partner with multiple mill relationships (which we are). It matters a lot if you're buying direct from a single small mill.

7. Geopolitical / regulatory risk

US-China tariffs on textile inputs have come and gone across recent administrations. EU CBAM and forced labor regulations (UFLPA in the US) are adding compliance burden to China-origin textile imports. Vietnam is largely outside both.

For buyers selling into US or EU retail, "not from China" is increasingly valuable as a downstream marketing claim and a regulatory hedge. Vietnam-origin PSF lets you make that claim.

The real comparison (cost landed to your port)

For 26 MT of 1.4D x 38mm SD RW PSF, FOB origin vs CIF Chittagong (Bangladesh), mid-2026:

Indicative. Real rates fluctuate, ATIGA preference depends on documentation compliance. Net of duty, Vietnam landed in Bangladesh is ~$2,500/26MT cheaper than China. At 100 MT/month, that's ~$10k/month savings.

When China is still the right call

• Very high volumes (500+ MT/month) where mill-gate price is the dominant factor and you have established China mill relationships
• Specialty specs (some specific dope-dyed colors, certain low-melt variants) that are concentrated at Chinese specialty mills
• Trial orders where Chinese Alibaba-trading-company lead times are faster for one-off buys
• Buyers with existing L/C and trade finance relationships with Chinese banks (cheaper financing)

When Vietnam is the better call

• You're selling into US/EU retail and need a non-China origin story
• You're an ASEAN or South Asian buyer and can claim ATIGA / CPTPP preference
• You want lower MOQs (5 MT vs 20-25 MT) and recurring monthly slots
• Your lead time window is short (Vietnam-to-South-Asia is faster than China-to-South-Asia)
• You're hedging tariff / regulatory risk on China

The short version

China is cheaper at the mill gate. Vietnam is often cheaper landed, especially for buyers in ASEAN / South Asia / EU. The math depends on your trade lane, your tariff regime, your volume, and your lead time window. "Always China" and "always Vietnam" are both wrong — the right answer is "do the math for your specific situation."
