On the Part B form, applicants are asked to identify their supplier or suppliers. If a licensee changes suppliers, how does the licensee report the change to API?
The licensee should consider this a revision of the licensed product and submit a new Part B (no other form is necessary unless other changes to the license need to be reported).

When are licensees required to pay the volume-of-sale royalty?
Licensees pay the volume-of-sale royalty after the first year of licensing. Reporting the amount of licensed diesel exhaust fluid sold is a requirement for license renewal.

How long does API expect licensees to store retain samples from diesel exhaust fluid batches?
API defers to paragraph 5.2 of ISO 22241 Part 3, which states that “samples should be kept safe for at least the shelf life of the volume of AUS 32.” Part 3 explains shelf life in paragraph 4.2.2.

Will API’s audit system take into account repeatability and reproducibility of the tests prescribed by ISO 22241?
Yes, API’s analysis of diesel exhaust fluids sampled in the marketplace will take into consideration the repeatability and reproducibility limits included in ISO 22241 Part 2.

What is a DEF license?
When an applicant has completed all of the steps necessary to become licensed, API will issue a document signifying that the applicant is licensed to display or use the API Diesel Exhaust Fluid Certification Mark in conjunction with its licensed diesel exhaust fluid. This document would be valid for one year and would be considered part of the Part C Diesel Exhaust Fluid licensing agreement.

When a licensee is asked to report volume of sale, is API asking for volume of licensed diesel exhaust fluid sold or volume manufactured?
API is asking for volume of licensed diesel exhaust fluid sold.

Will the licensing fee structure be reviewed periodically and if yes, how often?
Yes, API will review the licensing fee structure annually. If changes are necessary, they will be implemented only once per year.

What is an acceptable “Certificate of Analysis” that is supposed to accompany Part B of the application and how often should one be submitted?
A quality certificate as described in paragraph 5.5.1 of ISO 22241 Part 3 that shows test results for all tests required by ISO 22241 Part 1 would be sufficient. A new quality certificate would be required if the licensee switches suppliers or modifies its licensed product. Separate certificates would not be required if licensed fluid is manufactured at more than one site.

If a licensee has three sites that produce licensed product and a product from one of the sites fails API’s audit, how does this affect the company’s license?
A failing product discovered during an API audit does not automatically result in license suspension or revocation. The severity of the failure and the licensee’s response to the issue play a role in the status of the license.

Can a licensee add new trace codes for licensed products?
Yes, a licensee can always add trace codes to the ones on file with API.
