Dear Ms. Suta: In your letter dated December 10, 1999, on behalf of your client Seal Corporation, you requested a tariff classification ruling for "Pro-Long", a casing rim protectant which, when dispensed into a tire, prevents rust from accumulating on the rim therefore extending the life of the tire and wheel.
