Section 122 applies to most non-USMCA chemical and plastics imports at 15%. Some specialty chemicals fall under Section 232 derivatives (steel, aluminum, copper-related compounds in specific configurations). Active AD/CVD orders on specific chemical products from specific origins create stacking complexity. Section 232 pharma effective July 31 covers branded patented drugs; generics excluded.
Chemical imports cover an enormous range – bulk industrial chemicals, specialty chemicals, plastics, pharmaceuticals, agricultural chemicals. Section 122 applies broadly across these but interacts with multiple other regimes (Section 232 derivatives, AD/CVD orders, Section 232 pharma).
Effective duty stack for chemicals
Most non-USMCA chemicals: base MFN (0-6.5%) + Section 122 (15%). Effective rate 15-21%. China-origin specialty chemicals add Section 301 (often 25%) on top.
Section 232 pharma effective July 31 affects branded patented drugs at tiered rates; generics and biosimilars excluded.
Section 232 chemical derivatives
Section 232 derivatives expansion in 2025 brought some chemical products into Section 232 scope where the products are downstream of steel, aluminum, or copper. Component-level scope analysis identifies actual coverage.
AD/CVD on specialty chemicals
Active AD/CVD orders on specific chemical products from specific origins can dramatically increase effective duty. Scope rulings can confirm whether specific products fall under an order; misapplied AD/CVD is protestable.
Mitigation options
Classification review (chemical HTS in Chapter 28-39 has many boundary cases), USMCA qualification on Mexican-produced specialties, and AD/CVD scope rulings on borderline products.
Frequently asked questions
Are bulk chemicals in Annex II?
A few specific commodity chemicals are listed in Annex II as “natural resources cannot be produced in the United States in sufficient quantities.” Most specialty and industrial chemicals are not.
Does Section 232 pharma replace Section 122?
Yes – for goods within Section 232 pharma scope. Generics and biosimilars are excluded from Section 232; they pay Section 122 plus base.
How do AD/CVD and Section 122 interact?
Both can stack – AD/CVD applies on top of base MFN, and Section 122 also applies. AD/CVD rates are often very high (50-200%+); Section 122 surcharge sits on top.
Can Mexican-produced specialty chemicals qualify under USMCA?
Yes for goods meeting RVC and origin requirements. Specialty chemical RVC analysis depends heavily on input-material origins.
Are IEEPA refunds significant for chemical importers?
Yes – most non-USMCA, non-Section-232, non-AD/CVD chemicals paid IEEPA throughout 2025. Recoverable through CAPE.
