1. The “hourly rate” scorecard (3-axis vertical, 2025)

RegiónRMB/hUSD/h5 ejes premiumFoot-note
China (PRD/YRD)120–18015-25+ 10–20 USDcutters/steel local
Vietnam (HCM/Hanoi)90–14012–18+ 8–14 USD80 % tools imported
India (Pune/Chennai)70–1209–15+ 6–12 USDpower cuts 4 h/week avg

Labour is only 20-25 % of that rate—power, tooling and depreciation are global prices—so the gap is smaller than the wage gap suggests

2. Labour & electricity snapshot

ItemChinaVietnamIndia
CNC operator (month, inc. SI)950–1 050 USD480–560 USD380–460 USD
Industrial power (USD/kWh)0.090.060.08 (diesel back-up adds 0.02)
Skilled-tech availability95 %75 %60 %

→ Vietnam’s labour advantage is erased by brown-outs and technician turnover; India is cheaper but output/hour is 20-30 % lower

.


3. Supply-chain depth – the hidden MOQ

  • China: 50 km radius gives you pre-hardened steel, Sandvik tools, Schunk chucks, vacuum heat-treat same day.
  • Vietnam: 80 % of end-mills, gauges and special alloys imported from China/Japan—add 5-7 days on any urgent change .
  • India: alloy-steel shortage + port congestion; many shops keep 3-day diesel generator stock just to guarantee uptime .

4. Precision & automation

Medical or aerospace work that demands ≥95 % first-pass yield still ships to China for final ops & inspection, wiping out the labour saving

.


5. Logistics & lead-time

  • China → EU: rail 13–18 d / sea 18–25 d (USD 0.9–1.1 kg)
  • Vietnam → EU: sea 22–25 d (USD 0.7 kg) +5 d in peak season
  • India → EU: sea 28–32 d (USD 0.6 kg) + strikes/typhoon risk

For JIT lines the 3–7 d buffer advantage of China (via Chengdu or Xi’an rail) is often worth more than the 5 % price gap

.


6. Geo-politics & landed cost

  • China: still faces US 301 and upcoming EU CBAM carbon surcharge → +15–25 % landed.
  • Vietnam: zero tariff into EU (EVFTA) and exempt from most US 301 duties on machined parts → –8 % duty.
  • India: MFN tariff 6–8 % into EU; US duties product-specific; no carbon surcharge yet.

→ Vietnam enjoys the sweetest tariff window, but capacity is <1/10 of China—large volumes overflow back to China for semi-finish

8. Looking ahead (2025-2030)

  1. Vietnam wages + electricity rising 6–8 %/yr → hourly gap vs China <10 % by 2030.
  2. India infra gap closing slowly – good for high-labour, low-precision housings & brackets.
  3. China’s “dark-factory” push – unattended 3rd shift + renewable PPAs → using efficiency to offset tariffs; will keep high-mix, high-precision work .

Bottom line

“Tight-tolerance + fast turn around + one-stop” → still China.
“Zero-tariff + mid-volume + a little patience” → Vietnam.
“Labour-heavy + loose tolerance + high risk appetite” → India.

Hourly rate is only the ticket to the game; supply-chain depth, first-pass yield and tariff treatment decide who actually wins the order.
