Release of Articles Subject to Detention Without Physical Examination under This Import Alert:

In order to secure release of an individual shipment subject to detention without physical examination under this alert, the owner, consignee, and/or another responsible party to the shipment should provide evidence which demonstrates that the product does not bear or contain monomethylhydrazine (MMH) or Verpa bohemica. Such evidence may be in the form of a private laboratory analysis.

Such evidence should be submitted to the appropriate FDA Division Compliance Office for consideration, per the notice of detention. If a private laboratory is used, further information regarding private laboratory analyses is found in FDA's ORA Lab Manual, volume III, section 7. Following receipt and review of analytical results, the FDA may, at its discretion, collect and analyze audit samples before rendering a final decision on the admissibility of the article.

Removal from Detention Without Physical Examination (REMOVE FROM RED LIST):

In order to remove a firm's product from the Red List, information should be provided to the Agency to adequately demonstrate that the firm has resolved the conditions that gave rise to the appearance of the violation.
