Certification standards and testing landscape: Clean Label Project and beyond 💼
The Clean Label Project (CLP) is a leading third‑party certification program focused on identifying contaminants that matter most to consumers, including heavy metals, pesticides, and processing residues. CLP certification signals that a product has completed an independent testing panel and meets defined thresholds, offering a credible benchmark for brands prioritizing clean‑label claims. In practice, CLP evaluates finished products and, in some cases, key inputs, and assigns a seal that buyers look for during supplier qualification.
Beyond CLP, a growing ecosystem of credible confirmations includes Organic,Non‑GMO, and specific allergen testing programs. These certifications can interact with CLP in meaningful ways: a product can be CLP certified while also carrying organic or Non‑GMO claims, enhancing consumer confidence. However, it is important to understand what each certification covers—andwhat it does not. For example, some seals focus on contaminant screening, while others emphasize agricultural standards or traceability in sourcing. When evaluating options, ask for thescopeof testing (which contaminants, batch vs product level, limits) and whether the certification is current for the specific lot you’ll purchase.
Expert insight: manufacturers should pair third‑party testing with supplier disclosures and open access to certificates. This layered approach helps catch gaps that a single certificate might miss and supports more reliable private‑label programs.
