Phase One left hardware founders with a tariff map to manage
The Phase One agreement between the United States and China eased one escalation risk while preserving substantial tariffs. Hardware margins still depended on the product, duty schedule and timing of customs entry.

The announcement of a Phase One agreement between the United States and China on 13 December 2019 changed the direction of negotiations without returning trade to its earlier conditions. The US Trade Representative described commitments covering intellectual property, technology transfer, agriculture, financial services and currency, alongside additional Chinese purchases of US goods and services. Its announcement also said the United States would maintain substantial Section 301 tariffs. For a hardware startup, the immediate task was to translate this uneven policy relief into an accurate product cost and delivery promise.
Relief came in separate pieces
The first operational distinction was between tariffs already being collected and duties scheduled to start later. A USTR notice filed on 13 December and published on 18 December suspended the additional 15% duty scheduled for 15 December on products covered by Annex C of its August action. The suspension applied from the planned effective date and lasted until further notice. It did not remove every additional duty on Chinese goods.
The announcement described a future arrangement retaining 25% tariffs on approximately $250 billion of Chinese imports and 7.5% tariffs on approximately $120 billion. Those dollar figures described the trade covered by the announced tariff treatment, not startup losses or revenue available to alternative suppliers. The accompanying legal notice separately said a reduction for another product list would be addressed in a forthcoming notice. A purchasing team needed to preserve that timing distinction.
A bill of materials needed to account for landed costs
For an automation company or maker of connected devices, a supplier's factory quotation was only one part of the margin calculation. The team also needed to understand which imported article it was buying, its classification and customs value, the applicable additional duty and the party responsible for paying it. A finished device and separately imported components could create different exposures. The agreement headline could not determine those answers.
This made a model for each product more useful than applying one blanket percentage to all spending in China. An investor assessing gross margin could ask for a bridge from supplier price to delivered cost, with customs assumptions identified. Where classification remained unresolved, a range was more honest than treating the most favourable outcome as settled. Different tariff lists could produce materially different costs for technology products.

The tariff reduction followed the agreement
The agreement was signed on 15 January 2020, with the tariff reduction still to follow. A USTR notice published on 22 January then reduced the additional duty on the specified Annex A products from 15% to 7.5%, effective 14 February. Its annex applied the change to goods entered for consumption, or withdrawn from warehouse for consumption, from the stated time on that date.
- 13 December 2019
Phase One agreement announced
USTR outlines negotiated commitments and differentiated tariff treatment.
- 15 December 2019
Scheduled Annex C duties suspended
The planned additional 15% duty does not take effect; the notice is published on 18 December.
- 15 January 2020
Agreement signed
The subsequent tariff notice records signature and the scheduled entry into force.
- 14 February 2020
Annex A rate falls to 7.5%
The January notice halves the additional 15% duty for the specified products from this date.
Annex A and Annex C refer to distinct product lists in the August 2019 action; the rates do not describe all Chinese imports.
That sequence mattered to inventory planning. A purchase order date or a supplier's shipment date was not itself the legal trigger described in the notice. A company comparing delivery options had to consider the relevant customs entry and the cost of waiting, including stockouts or delayed customer acceptance. Any potential duty saving needed to be weighed against those costs. The reduced rate had not applied when the agreement was first announced.
Customer contracts could absorb the benefit
Whether a lower duty improved startup economics depended partly on commercial terms. A contract with a fixed price could leave the seller exposed to a cost increase and allow it to retain some later relief. A contract with a duty adjustment mechanism could pass changes through to the buyer. Distributors and contract manufacturers could also have their own pricing and inventory arrangements between the policy change and the startup's invoice.
The same distinction applied to demand. A customer could welcome a less confrontational negotiating environment and still postpone a plant investment or hold down equipment budgets. Founders needed to ask what had actually changed in a customer's approval process. A diplomatic announcement was insufficient evidence to reverse a conservative sales forecast or hire ahead of orders that remained unsigned.
Relocation remained an engineering decision
Supplier diversification could still be worthwhile, although tariffs alone could not establish whether a rapid move would pay for itself. A different manufacturing site could require tooling, process validation, quality audits, logistics changes and new working capital. For a young hardware business, those costs could be substantial before the first acceptable production unit arrived.

A useful comparison therefore involved delivered cost, yield, reliability and the cost of maintaining an alternative. Moving final assembly was not enough evidence by itself that a different duty treatment would apply; the proposed arrangement required a proper origin and classification assessment. The investment case for a second supplier should remain credible after including qualification time and the possibility that trade policy changed again.
Commitments still needed to become usable conditions
The announcement's commitments on intellectual property and technology transfer addressed concerns relevant to innovative firms. But an announced agreement and a promise of dispute resolution were not proof that a particular licence, partnership or manufacturing relationship had become safer. Contract rights, access to technical information and the ability to enforce an agreement still required scrutiny of each transaction.
Venture investors could revise their trade scenarios while retaining an allowance for the risks that remained. A company that could explain the remaining tariff burden, show where relief would reach its margin and price the cost of alternatives offered a more credible financing case. Phase One narrowed an immediate source of uncertainty while leaving founders with detailed execution work.
Investment implications
- The agreement suspended a scheduled tariff increase; a separate reduction on another product list took effect in February 2020.
- Margins depended on the applicable product classification, customs value and entry timing, rather than a single average tariff assumption.
- Supplier changes still required economic and engineering justification after negotiations improved.
