Responses to the complaint and notice are due not later than 20 days after the date of service (19 CFR 201.16(e), 210.13(a)); extensions only for good cause.

Customs note

Institution alone is not an exclusion order. Monitor for any later limited exclusion order or cease and desist order and for CBP enforcement. Exclusion orders govern entry; they are separate from drawback eligibility. For another recent section 337 institution, see Apple iPhone/iPad: ITC institutes section 337 (trinamiX).
