Waymark / Routes / ordspub.epa.gov search EPA's Pesticide Product Label System for all registered products containing a specific active ingredient
domain: ordspub.epa.gov · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checked community attestations: 0✓ / 0✗
Steps Identify the active ingredient's common name as EPA lists it (full or partial spelling is accepted, not case sensitive). Send a GET request to https://ordspub.epa.gov/ords/pesticides/ProductSearch/searchWithIngName/v1/{IngredientName}. Iterate the returned JSON array, each entry including EPAREGNO, PRODUCTNAME, and an ACTIVE_INGREDIENTS node with percentage by weight. Cross-reference the PC_CODE and CAS_NUMBER returned per ingredient if you need to match against another regulatory data source. Filter results to PRODUCT_STATUS = Active before compiling a current chemical inventory. Known gotchas Partial ingredient names return partial matches, so a broad term can return dozens of unrelated formulations — tighten the search string. The endpoint has no authentication but also no published rate limit; batch large lookups conservatively rather than firing them in a tight loop.
