ECCN 1C008
NSATNon-fluorinated polymeric substances as follows .
What This ECCN Covers
ECCN 1C008 controls specified non-fluorinated polymeric substances — including certain polyimides, polyarylene ethers/ketones, and other high-performance polymers — defined by composition and form. These heat-resistant, high-strength polymers are used in aerospace and electronics, and are controlled for National Security and Anti-Terrorism reasons.
Who needs to check this?
Specialty polymer manufacturers and distributors, and aerospace or electronics suppliers sourcing high-temperature engineering plastics and films.
Compliance tip
Classification depends on the specific chemistry and physical form described in the entry — confirm your material matches before assuming control, as many commercial polymers fall outside. Check the NS and AT Country Chart columns and the entry's License Exception paragraph.
Items Covered
- a.Imides as follows:
- 1. Bismaleimides;
- 2. Aromatic polyamide-imides (PAI) having a 'glass transition temperature (Tg)' exceeding 563 K (290 °C);
- 3. Aromatic polyimides having a 'glass transition temperature (Tg)' exceeding 505 K (232 °C);
- 4. Aromatic polyetherimides having a 'glass transition temperature (Tg)' exceeding 563 K (290 °C);
- d.Polyarylene ketones;
- e.Polyarylene sulfides, where the arylene group is biphenylene, triphenylene or combinations thereof;
- f.Polybiphenylenethersulphone having a 'glass transition temperature (Tg)' exceeding 563 K (290 °C).
