The disclaim on a Lacey Act declaration (PG01 Disclaimer field). Filing it short-circuits the message set to OI + PG01 — no plant lines are declared. Filer-supplied (confidence 1.0), or inferred as code A when the apply is confident the item carries no Lacey-regulated plant material. Only a high-confidence inference is honored, since a wrong disclaim under-files a declaration that was owed; a plausibly CITES/ESA-protected species is always declared, as no statute exclusion covers one.
