| Label compliance |
Ingredient list, nutrition information, serving size, net quantity, allergen declaration, directions, warnings, and contact information. |
Final market-specific artwork reviewed against the destination country’s current labeling rules. |
Label claims and required statements must match the tested formula and the regulations of the selling market. |
High |
| Claims substantiation |
Evidence supporting claims such as “high protein,” “low sugar,” “natural,” “organic,” or “free from.” |
Approved claim file containing calculations, certificates, test results, and regulatory review. |
Do not use a claim unless it is legally permitted and supported by current product-specific evidence. |
High |
| Organic or specialty certification |
Whether specialty claims are certified by an authorized body for the relevant market. |
Valid certificate identifying the operator, product scope, processing site, and covered ingredients. |
Use certified claims only when the certificate covers the complete product or clearly identifies the certified portion. |
Medium |
| Athlete-focused testing |
Additional controls for prohibited substances when the product is marketed to competitive athletes. |
Current certification from a recognized sport-supplement testing program, including product and lot coverage. |
Certification should be independently verifiable and current for the exact product, not merely for the manufacturing facility. |
Medium |
| Commercial and Online Supplier Reliability |
