Tariff volatility, geopolitical risk, and trade-policy whiplash made China-only sourcing a liability for many Amazon sellers. Diversification is not just moving factories. It is matching the product, the cost structure, and the lead-time profile to alternative origins. This skill builds the migration plan.
When to use this
- Heavy or full China exposure and tariff-policy risk is real.
- Stacked duties (Section 301, reciprocal or other country-specific tariffs, antidumping where relevant) are eroding margin.
- The seller wants a backup supplier without a full move.
- Planning a new SKU and deciding where to source from the start.
The framework. The Diversification Map
For each candidate origin (Vietnam, India, Mexico, domestic assembly, etc.), score on five factors.
| Factor | What to check |
|---|---|
| Duty + tariff | HS code base rate plus all applicable add-on duties for that origin (Section 301, reciprocal or other country-specific tariffs, antidumping where relevant). Check the current rate, the regime shifts |
| Unit cost | Factory price for comparable quality |
| Lead time | Production + ocean/air freight + customs |
| MOQ | Often higher in alternative origins still ramping |
| Quality and reliability | Sample tested, references, IP protection |
A clear winner per factor is rare. the diversification is usually about reducing risk while accepting a higher unit cost or longer lead time.
Step by step
-
Collect inputs. Current China supplier details (price, MOQ, lead time, HS code, total tariff), the product, current monthly volume, the seller's risk tolerance.
-
Compute current total landed cost. With current tariffs (use amz-tariff-calculator). This is the baseline.
-
Identify 2-3 candidate alternative origins. Vietnam (apparel, accessories, electronics assembly), India (textiles, leather, certain home goods), Mexico (USMCA benefits for some categories), domestic assembly (specialty, low-volume).
-
Source quotes. Contact suppliers or use industry directories.
-
Compute landed cost per origin. Through amz-tariff-calculator. Compare to the China baseline.
-
Build the migration roadmap. Start with samples and a small parallel production run before any volume shift. Most sellers diversify gradually, keeping China for some SKUs while shifting others.
-
Plan the dual-source state. Many sellers settle on a 70/30 or 50/50 split for resilience, not a full move.
-
Run the quality check, then deliver.
Output format
## Sourcing Diversification Plan. [product]
Current origin: China. Total landed cost: [$/unit]
Current tariff exposure: [%]
### Candidate origins
1. [country] . duty + tariff [%] . landed cost [$/unit] . lead time [d] . MOQ [N] . notes
...
### Recommended path
[primary candidate, why]
### Migration roadmap
Phase 1 (weeks 1-6): Samples + small parallel run
Phase 2 (weeks 7-16): Production at the new origin
Phase 3 (weeks 17+): Dual-source split [%] / [%]
### Risk reduction
[which trade-policy risks the diversification removes]
Worked example
A home-goods SKU sourced from China at 4.20 USD landed, where the stacked China-origin duties (base duty plus the add-on tariffs that apply to this HS code and origin) add most of the gap from the 2.80 factory price. Vietnam alternative: factory price 3.20, a different and currently lower duty stack for this origin, landed 4.40. Cost slightly higher but the China-specific tariff exposure is removed. Migration: order 200 units sample from a vetted Vietnam supplier (6 weeks), test quality and lead-time reliability. If clean, place a 5,000 unit parallel order while continuing China for the bulk. After 3 months, split production 40 Vietnam / 60 China for resilience. The seller is now insulated from a tariff hike on the China-origin duty stack for this SKU, at a small landed-cost premium that is manageable. Verify the current duty stack for each origin before committing. the rates shift.
Quality check
- Current landed cost is computed before any comparison.
- 2-3 candidate origins are scored on all five factors, not just price.
- The plan starts with samples and parallel runs, not a full switch.
- A dual-source split is recommended for resilience, not a binary move.
- Trade-policy risks are explicitly named, not vague "geopolitical risk".
Common mistakes
- Cost-only comparison. Vietnam may be slightly more expensive but eliminates tariff exposure. that risk reduction is real value.
- All-or-nothing move. Full migration before testing the new supplier produces quality and lead-time surprises.
- Forgetting MOQ and lead time. Alternative origins often have higher MOQs and longer lead times during ramp-up.
- No backup plan. Single-source from any country, including the new one, is itself a risk.
