What would a 100% tariff on Chinese imports mean for supply chain costs?

A 100% tariff would effectively double the landed cost of goods imported from China. For companies currently sourcing from China, this represents a significant cost shock that could impact margins, pricing, and competitiveness. Companies would need to evaluate alternative sourcing strategies, including nearshoring to Mexico or Vietnam, domestic production, or strategic inventory pre-positioning before policy implementation.

Which industries would be most affected by this tariff escalation?

Virtually all industries reliant on Chinese manufacturing would face impact, including retail, electronics, automotive, consumer goods, appliances, furniture, and textiles. Retail and consumer electronics are particularly vulnerable due to high volume of Chinese imports and thin margins that limit pricing flexibility.

How should supply chain teams respond to this threat?

Immediate actions include: (1) conducting detailed sourcing audits to quantify China exposure by product category and timeline; (2) initiating preliminary assessments of alternative suppliers in Vietnam, India, Mexico, and other nations; (3) developing tariff scenario models to understand cost impacts; (4) accelerating negotiations with current suppliers on pricing and terms; and (5) communicating with finance and commercial teams on potential price adjustments and inventory strategies.

Is this threat unprecedented compared to previous trade actions?

Yes. While the Trump administration implemented targeted tariffs (Section 301 actions) averaging 15-25% on specific product categories in 2018-2020, a blanket 100% tariff on all Chinese imports would be structurally different in scope, scale, and severity. This represents an escalation from previous trade disputes and suggests a more fundamental shift in U.S. trade policy.

What is the timeline for implementation and what should companies do now?

The article does not specify an implementation timeline, but the public threat signals serious policy consideration. Supply chain teams should treat this as a high-priority planning scenario and begin immediate contingency planning, supplier diversification analysis, and stakeholder communication. Waiting for confirmation of policy timing increases execution risk.

Trump 100% Tariff Threat Escalates U.S.-China Trade War

May 18, 2026

The signal

-China trade conflict. This represents an unprecedented level of tariff threat that could fundamentally reshape global supply chains and procurement strategies. For supply chain professionals, this development creates immediate uncertainty around cost structures, supplier relationships, and inventory planning.

A 100% tariff would effectively double the landed cost of Chinese imports, forcing companies to either absorb costs, raise consumer prices, or rapidly restructure sourcing strategies. The scale and scope of this threat—applying to general imports rather than targeted sectors—creates systemic risk across nearly all industries reliant on Chinese manufacturing. The strategic implications extend beyond simple cost increases.

Supply chain teams must begin scenario planning around alternative sourcing locations, nearshoring strategies, and inventory positioning ahead of potential policy implementation. -China trade relations rather than temporary negotiating postures.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

immediate

What if 100% tariffs are implemented on all Chinese imports effective immediately?

Model the impact of a 100% tariff applied to the cost of goods imported from China across all product categories. Assume tariff applies to all in-transit and future shipments from China. Evaluate total landed cost increase, margin impact by product line, and identify which SKUs would become uneconomical at current retail price points.

Run this scenario

Simulation Suggestion

this month

What if you need to shift 40% of China sourcing to Vietnam and Mexico within 6 months?

Model a sourcing diversification scenario where 40% of current Chinese supplier volume is reallocated to Vietnam and Mexico. Adjust procurement lead times (Vietnam +2 weeks, Mexico +1 week), transportation costs (ocean freight from Vietnam +$200/TEU, Mexico via truck/air), supplier reliability assumptions, and quality control timelines. Evaluate inventory buffer requirements and working capital impact.

Simulation Suggestion

this week

What if supply chain lead times extend 3-4 weeks due to customs delays and policy uncertainty?

Model increased customs clearance times (add 7-10 days) and logistics network congestion (add 5-7 days) resulting from tariff policy implementation uncertainty. Evaluate demand planning accuracy, safety stock requirements, service level impact, and inventory carrying costs. Assess which SKU categories require emergency inventory positioning.
