Brussels Resists U.S. Demands Over Supply Chain Laws
The European Union rejected fresh trade pressure from the United States on Friday. Brussels pushed back against Washington’s claims that the bloc is enabling Chinese tariff evasion and resisting demands to alter flagship environmental and human rights regulations.
Ambassador Andrew Puzder Issues Ultimatum on X
The U.S. ambassador to the EU, Andrew Puzder, asserted Friday that the bloc must align two landmark supply chain laws with the bilateral trade agreement struck last year. “Now it’s time for the EU to deliver,” Puzder posted on X.
He accompanied the message with an official U.S. government document outlining a series of grievances against the regulations. The document warned that the United States would pursue necessary actions to counter unreasonable burdens on domestic commerce if the concerns remain unaddressed.
The Battle Over CSDDD and CSRD Regulations
European Commission spokesperson Arianna Podesta confirmed that Brussels and Washington are maintaining constructive exchanges on both tariff and non-tariff matters. However, Podesta drew a firm line regarding internal governance. She stated that neither the EU’s rules framework nor its regulatory autonomy are up for negotiation.
The friction centers heavily on the Corporate Sustainability Due Diligence Directive (CSDDD), which mandates that large corporations address adverse human rights and environmental impacts throughout their global supply chains. It also involves the Corporate Sustainability Reporting Directive (CSRD), requiring firms to disclose detailed metrics regarding their climate impact, emissions, and mitigation strategies.
U.S. Claims of Unfair Disadvantage
According to the U.S. government document, the extraterritorial reach and costly due diligence burdens of these directives threaten to disadvantage American businesses attempting to compete on a level playing field within the EU market.
Although the European Union has previously scaled back the scope of both mandates—delaying their rollout and exempting smaller companies under pressure from businesses both inside and outside the bloc—the U.S. assessment maintains these adjustments are insufficient.
The diplomatic friction follows comments made Thursday by Puzder criticizing the bloc’s Carbon Border Adjustment Mechanism (CBAM), which he charged was “a tariff in substance, no matter the ‘climate policy’ label”.
White House Targets Transshipment and China
Compounding the trade tensions, the White House released a report Thursday identifying the European Union among dozens of trading partners posing risks regarding illegal transshipment from China. The practice involves routing goods through third-party nations to bypass sweeping tariffs instituted by President Donald Trump.

The White House report, which also singled out Canada, Mexico, and Japan, indicated that future enforcement will leverage artificial intelligence to detect illicit trade maneuvers.
Addressing the transshipment allegations, Podesta maintained that the EU shares the U.S. objective of combating customs fraud. She noted that Brussels is actively engaging with Washington to evaluate the report’s implications, emphasizing that the document itself found EU transshipment risks to be embedded within broad legitimate trade flows.
