Most of the tariff coverage on this blog (IEEPA fentanyl duties, Section 301, the now-expired reciprocal tariffs) involves broad, country-wide rates set by executive action. Antidumping (AD) and countervailing duty (CVD) orders work differently: they are narrow and product-specific, and only apply when a formal petition names the exact product category, which is rarely the case for standard plastic packaging.
Antidumping duties address foreign producers selling goods in the U.S. below fair value ("dumping"). Countervailing duties address foreign government subsidies that give producers an unfair price advantage. Unlike Section 301 or IEEPA tariffs, which the executive branch imposes unilaterally, AD/CVD orders result from a formal investigation process run jointly by the Department of Commerce and the U.S. International Trade Commission (ITC).
Because AD/CVD rates are calculated from actual pricing and cost data on a per-company basis, they can run far higher than blanket tariffs: into the triple digits for individual producers found to be dumping aggressively. These rates also don't expire on a political timeline the way Section 122 or IEEPA tariffs have. They remain in place until a sunset review, typically every five years, unless revoked earlier.
AD/CVD orders are product-specific. A buyer sourcing PET bottles isn't affected by an order covering polypropylene corrugated boxes, and vice versa. Most standard packaging categories have never been named in a petition. The broad country-level rates are tracked separately on the tariff page.
