China trade data add a measurable test to the Trump China agenda
China’s 14 October customs release provides new evidence on trade flows after the September Trump–Xi meetings. Goods trade with the United States increased 4.1% year on year to CNY 3.18 trillion in January–September. China’s total goods trade reached CNY 39.94 trillion, up 18.8%. These are cumulative values, not a measurement of the effect of the latest negotiations. [1]
Reuters reported September export growth of 36.3% and import growth of 31% in US dollar terms. Its poll had expected 25.5% and 24.5%, respectively. The government release gives September growth of 29.6% for exports and 24.6% for imports in yuan. The currency bases differ; the figures should not be combined into one series. [1–2]
What the figures do and do not establish
For tariff planning, the relevant background remains USTR’s 27 September announcement: the Board of Trade recommended goods representing USD 30 billion on each side for potentially more favorable treatment. USTR described future possibilities, rather than a blanket tariff reduction already available to importers. Separately, its 7 October notice confirms that the July and August 2018 Section 301 actions, as modified, remain in effect, subject to further modification. These are background measures, not new agreements announced this week. [3–4]
SEMUDMEX View The practical distinction is between an announced negotiating scope and an enforceable entry treatment. A buyer should connect any claimed saving to the exact product description, applicable tariff provision and effective entry date. A supplier’s quotation or inclusion in a negotiating list should not by itself be treated as proof of a lower duty.
SEMUDMEX View The new trade release supports monitoring actual flows while negotiations continue. It does not isolate Chinese purchases of US goods under specific commitments, establish delivery of rare earth shipments, or demonstrate that tariff relief caused the September acceleration. For Mexican supply chains, the useful next step is to compare confirmed landed costs by product and retain origin documentation for processing performed in Mexico.
Hard Data
September 2026, USD basis: exports +36.3%; imports +31%, year on year. Reuters poll: +25.5% and +24.5%. January–September, CNY basis: total goods trade 39.94 trillion; trade with the United States 3.18 trillion, +4.1%. [1–2]
US content guidance takes effect for covered Mexican and Canadian goods
BIS guidance became applicable on 14 October at 12:01 a.m. Eastern Time, advancing beyond the 9 October public inspection text. [5]
US content includes qualifying parts wholly obtained, entirely produced or substantially transformed domestically, plus previously uncounted qualifying metal value. Steel must be melted and poured in the United States; aluminum and copper must be smelted and cast there. Double counting is excluded. [5]
For covered Annex I C articles, clause 2 d applies a 25% duty to non-US content, with a 15% minimum effective duty on the imported product. Eligibility requires both the relevant product coverage and USMCA qualification; the rule does not create a general exemption for all Mexican exports. [6]
SEMUDMEX View Maintain a separate calculation of US value rather than substituting a regional value content percentage. Reconcile the bill of materials, supplier declarations and metal production records to the entered value. Any allocation of qualifying metal value should show that it has not already been included through a qualifying part.
Hard Data
Illustration under clause 2 d only: entered value USD 100,000; supported US content USD 20,000; 25% × USD 80,000 = USD 20,000. With US content of USD 60,000, the calculation gives USD 10,000, but the 15% floor produces USD 15,000. Assumes this clause applies and no lower alternative treatment applies; other duties are excluded. Calculation by SEMUDMEX from [6].
New USMCA labor review affects customs settlement at a textile facility
On 13 October, USTR requested Mexico’s review of alleged freedom of association and collective bargaining violations at Carolina Performance Fabrics in Guanajuato. It also announced suspension of liquidation of unliquidated entries from the facility. Mexico has 10 days to accept the review and, if it agrees, 45 days from the request to complete it. The allegations remain subject to review. [7]
SEMUDMEX View Liquidation is the final customs settlement of an entry. The announced suspension should not be treated as a general import ban. Importers should identify the producing facility behind affected shipments, preserve entry records and monitor the review before treating their customs exposure as closed. This is a supply chain compliance issue extending beyond any single end-use sector.
Hard Data
Request: 13 October 2026. Acceptance period: 10 days. Review period if accepted: 45 days from the request. Measure announced: suspension of liquidation for the facility’s unliquidated entries. [7]
