WHY YOU SHOULD LOOK FOR THE API MONOGRAM AND
LICENSE NUMBER ON "API" PRODUCTS.
Manufacturers who want to apply the API monogram on their equipment and materials must apply to API for a license to do so. If API determines, through an on-site audit, that a manufacturer has the capability to produce products that consistently conform to API specifications, API shall license that manufacturer to use the API monogram and their license number on specific products made at specific locations. Although any manufacturer may claim that its products meet API specifications without monogramming them, only manufacturers with a license from API can apply the API monogram to their products.
WHEN THE API MONOGRAM, IN CONJUNCTION WITH THE MANUFACTURER'S LICENSE NUMBER, ACTUALLY APPEARS ON THE PRODUCT, IT CONSTITUTES A WARRANTY BY THE LICENSED MANUFACTURER (LICENSEE) TO THE AMERICAN PETROLEUM INSTITUTE AND TO THE PURCHASER OF SUCH EQUIPMENT OR MATERIALS: THAT THE PRODUCT COMPLIES IN EVERY DETAIL WITH THE APPLICABLE STANDARDS AND SPECIFICATIONS. NO SUCH WARRANTY TO API EXISTS WHEN THE MONOGRAM DOES NOT APPEAR.
API DOES NOT RECOGNIZE CLAIMS ABOUT API-SPECIFIED PRODUCTS TO WHICH MANUFACTURERS DO NOT APPLY THE MONOGRAM. USERS WHO WANT AN "API STANDARD PRODUCT" FROM AN API LICENSED MANUFACTURER SHOULD REQUIRE IN THEIR PURCHASE ORDER THAT THE MONOGRAM AND THE MANUFACTURER'S LICENSE NUMBER APPEAR ON THE PRODUCT ITSELF.
