NDC Architecture.

4-4-2? 5-3-2? 5-4-1? The National Drug Code (NDC) format is permanent. Choosing the wrong structure can block future product launches. We help you architect a scalable NDC strategy from Day 1.

The SPL Validator.

FDA rejects thousands of listings for XML syntax errors or UNII code mismatches. Our validator pre-checks your data against FDA's schema to ensure first-pass acceptance.

Import Support

Foreign Manufacturer?
We link it.

Importing drugs to the US? You need a US Agent and a compliant establishment registration. We handle the cross-border linkage to prevent “Unapproved Drug” detentions at customs.
