Trade Remedy Digest — 2026-11-06

Summary

China concluded sunset reviews and extended both anti-dumping and countervailing duties on US-origin n-propanol for another five years, keeping very high AD rates (254.4%–267.4%) and CS rates (34.2%–37.7%) in place. The US issued a preliminary anti-dumping determination on CBS rubber accelerator from China at a very high margin (285.94%). The EU opened a safeguard investigation covering PET resin chemicals and key upstream inputs (terephthalic acid, MEG, purified isophthalic acid), which could add a new layer of trade risk on top of existing AD/AS measures.

By Product

n-Propanol (NPA) (HS 29051210)

• Case type / Stage: anti-dumping / sunset

• Trade route: United States → China

• Measure / rate: 254.4%–267.4% (Dow 254.4%; OQ Chemicals 267.4%; all other US companies 267.4%)

• What changed: MOFCOM Announcement No. 54 of 2026 concluded the expiry review and extended the anti-dumping duty on US-origin n-propanol for a further 5 years from 6 November 2026; rates unchanged from the 2020 original measure.

• Procurement impact: US-origin NPA remains effectively priced out of the Chinese market; buyers should keep non-US supply sources and expect continued tightness in domestic/alternative-origin NPA and its derivatives (n-propyl acetate, pharmaceutical intermediates).

• Case type / Stage: countervailing / sunset

• Trade route: United States → China

• Measure / rate: 34.2%–37.7% (Dow 37.7%; OQ Chemicals 34.2%; all other US companies 37.7%)

• What changed: MOFCOM Announcement No. 55 of 2026 concluded the expiry review and extended the countervailing duty on US-origin n-propanol for a further 5 years from 6 November 2026; rates unchanged.

• Procurement impact: Combined with the AD duty, US-origin NPA faces a prohibitive total duty burden; procurement should continue to avoid US-origin material and monitor alternative-origin pricing pressure.

N-Cyclohexylbenzothiazole-2-sulfenamide (CBS) rubber accelerator (HS 2934.20.8000)

• Case type / Stage: anti-dumping / preliminary
• Trade route: China → United States
• Measure / rate: 285.94% dumping margin (cash deposit 281.69% after subsidy offset)
• What changed: US Commerce issued a preliminary affirmative anti-dumping determination on CBS from China on 4 November 2026; final determination expected 12 January 2027. The case also includes a countervailing investigation opened 28 May 2026.
• Procurement impact: US buyers of Chinese CBS face very high preliminary deposit requirements, pushing them toward alternative origins or non-Chinese suppliers; Chinese exporters face loss of US market access and possible diversion of volumes to other regions.

PET resin chemicals (PET, terephthalic acid, mono-ethylene glycol, purified isophthalic acid)

• Case type / Stage: safeguard / initiation
• Trade route: n/a → European Union
• Measure / rate: not stated
• What changed: The European Commission opened a safeguard investigation on 6 November 2026 covering certain PET resin chemicals across the PET value chain, including virgin/recycled PET, PET glycol, terephthalic acid, mono-ethylene glycol and purified isophthalic acid, citing high import pressure and global overcapacity. Provisional measures possible if conditions are confirmed; definitive measures would follow within 200 days of any provisional step.
• Procurement impact: Adds new uncertainty for EU sourcing of PET-chain chemicals already subject to AD/AS measures (PET from China, PET from India, PTA from Korea/Mexico, MEG from Saudi Arabia/USA); buyers should prepare for possible quotas/tariffs and diversify supply, while exporters to the EU should monitor the investigation timeline.
