The importer may, during the 30-day period, establish that any of the circumstances described in § 133.22(c) or § 133.23(d) are applicable. Extensions of the 30-day time period may be freely granted for good cause shown.

From the time merchandise is presented for Customs examination until the time a notice of detention is issued, Customs may disclose to the owner of the trademark or trade name any of the following information in order to obtain assistance in determining whether an imported article bears an infringing trademark or trade name. Once a notice of detention is issued, Customs shall disclose to the owner of the trademark or trade name the following information, if available, within 30 days, excluding weekends and holidays, of the date of detention:

(c) Disclosure to the trademark or trade name owner. At any time following presentation of the merchandise for CBP's examination, but prior to seizure, CBP may release a sample of the suspect merchandise to the owner of the trademark or trade name for examination or testing to assist in determining whether the article imported bears an infringing trademark or trade name. To obtain a sample under this paragraph, the owner of the mark must furnish to CBP a bond in the form and amount specified by CBP, conditioned to indemnify the importer or owner of the imported article against any loss or damage resulting from the furnishing of the sample by CBP to the owner of the mark. CBP may demand the return of the sample at any time. The owner must return the sample to CBP upon demand or at the conclusion of the examination or testing, whichever occurs sooner. In the event that the sample is damaged, destroyed, or lost while in the possession of the trademark or trade name owner, the owner must, in lieu of returning the sample, certify to CBP that: “The sample described as [insert description] and provided pursuant to 19 CFR 133.25(c) was (damaged/destroyed/lost) during examination or testing for trademark infringement.”
