Moldova** - **Unit Price:** $90 × 1,000 = $90,000 - **Packaging:** $1.75 × 1,000 = $1,750 - **Tooling Cost (annual):** $2,500 - **Defect Rate:** 2% × unit price × 1,000 = 0.02 × $90 × 1,000 = $1,800 - **Ocean Transportation:** $3,300 - **Customs Duty:** 5% × (unit price × 1,000) = 0.05 × $90,000 = $4,500 - **Land Freight:** $3 × 1,000 = $3,000 **Total (Moldova):** $$ 90,000 + 1,750 + 2,500 + 1,800 + 3,300 + 4,500 + 3,000 = \boxed{106,850} $$ --- #### **4. USA** - **Unit Price:** $100 × 1,000 = $100,000 - **Packaging:** $2 × 1,000 = $2,000 - **Tooling Cost (annual):** $500 - **Defect Rate:** 1% × unit price × 1,000 = 0.01 × $100 × 1,000 = $1,000 - **Ocean Transportation:** $0 - **Customs Duty:** N/A - **Land Freight:** $4 × 1,000 = $4,000 **Total (USA):** $$ 100,000 + 2,000 + 500 + 1,000 + 0 + 0 + 4,000 = \boxed{107,500} $$ --- ## **Summary Table** | Supplier | TCO | |----------|----------| | China | $103,580 | | Ukraine | $103,640 | | Moldova | $106,850 | | USA | $107,500 | --- ### **Answers to Questions** #### **2.1. Which supplier has the highest cost?** - **USA** ($107,500) #### **2.2. Which supplier has the lowest cost?** - **China** ($103,580) #### **3. How much more expensive is the domestic option (USA) compared to overseas options?** - Compared to **China**: $107,500 - $103,580 = **$3,920 more expensive** - Compared to **Ukraine**: $107,500 - $103,640 = **$3,860 more expensive** - Compared to **Moldova**: $107,500 - $106,850 = **$650 more expensive** #### **4. Which supplier would you choose? Risks and benefits?** - **Choose China (Lowest TCO)** - **Benefits:** Lowest cost, potentially higher profit margin. - **Risks:** Higher defect rate (6%), longer supply chain, possible geopolitical or tariff risks, longer lead times. - **Alternative—USA** - **Benefits:** Lowest defect rate (1%), fastest delivery, no customs or ocean transport, supports local economy. - **Risks:** Highest cost, but lower risk of supply chain disruption, better quality control. --- **Final Recommendation:** **China** provides the lowest TCO, but you must weigh the higher defect rate and potential supply chain risks against the cost savings. If reliability and consistent supply are crucial, the USA is a safer but more expensive choice.

The total cost of ownership (TCO) includes all sourcing and transportation expenses, defect costs, and tooling for each supplier. Calculations reveal that overseas suppliers like China offer lower TCO despite higher defect rates, while domestic options like the USA are more expensive but potentially more reliable. The optimal choice balances cost savings with quality and supply chain stability.
