Confidentiality of origin information limits disclosure, restricts use to customs administration, and requires notice before wider disclosure. Confidential information collected under the origin-determination rules is protected from disclosure where access would impede law enforcement, contravene applicable law, or prejudice the competitive position of the person concerned. The Parties must use or disclose such information only for the administration and enforcement of origin determination or customs matters, unless the provider consents. Where domestic law requires disclosure, notice should be given where possible, preferably in advance.
