De Minimis Rule

The phrase comes from the Latin maxim de minimis non curat lex — "the law does not concern itself with trifles." In political economy it appears wherever regulators need a cutoff below which compliance costs would exceed the benefits of enforcement. The rule shows up in three particularly important areas:

• Customs and trade. Most jurisdictions waive duties and formal entry procedures for low-value shipments. The United States raised its de minimis threshold to USD 800 per shipment under the Trade Facilitation and Trade Enforcement Act of 2015, one of the highest in the world. The European Union eliminated its EUR 22 VAT de minimis on imports in July 2021, and a customs duty exemption still applies below EUR 150. These thresholds became politically contentious because e-commerce platforms — especially Chinese shippers such as Shein and Temu — routed enormous volumes of small parcels through them, prompting U.S. executive action in 2025 to curtail the carve-out for shipments from China.

• Subsidies under WTO law. The Agreement on Subsidies and Countervailing Measures sets de minimis floors for countervailing duty investigations (generally 1% of the product's value, or 2% for developing countries), below which an investigation must be terminated. The Agreement on Agriculture similarly allows trade-distorting domestic support up to de minimis percentages of production value.

• Competition and regulatory law. The European Commission's De Minimis Notice exempts agreements between firms with small combined market shares from Article 101 TFEU scrutiny, on the theory that they cannot appreciably restrict competition.

The underlying logic is administrative efficiency: enforcement resources are scarce, and very small transactions rarely cause measurable harm. The political controversy is that "small" aggregates. A threshold designed for the occasional tourist parcel can, at internet scale, swallow billions of dollars of taxable or regulated commerce — turning a technical exemption into an industrial-policy question.
