How IEEPA tariffs hit chemicals and plastics
- Annex II. The April 2025 reciprocal order exempted energy and energy products and certain critical minerals, among other categories, through Annex II.
- September 8, 2025 changes. An order effective September 8, 2025 removed several items from Annex II, including aluminum hydroxide, certain resins, and silicones, so those products paid the reciprocal tariff from that date. It also added other items, including some critical minerals.
- China. China-origin chemicals also paid the IEEPA duty tied to synthetic opioids unless exempt.
What to check
Check each HTS code against Annex II as it stood on the entry date. A product exempt in the spring may have paid reciprocal duty after September 8, 2025, and the reverse.
Records to have ready
- HTS codes by product and entry dates
- ES-003 and ES-022 reports
