Every botanical-ingredient supplier with credible aspirations lists the same three acronyms on their quality page: GACP, GMP, HACCP. The implication is that together they cover the full quality story. They mostly do — but each addresses a different layer of the chain, and confusing them is how quality gaps go unnoticed.
This piece spells out what each framework covers, where its boundaries sit, and what "aligned with" versus "certified to" means in practice.
GACP — Good Agricultural and Collection Practice
GACP governs the cultivation, wild-collection, and primary post-harvest handling of botanical raw material. The reference framework is the WHO's "Good agricultural and collection practices for medicinal plants" (2003), with regional adaptations from the European Medicines Agency (EMA/HMPC) and various national pharmacopoeias.
What GACP actually specifies:
- Site selection — soil, water, surrounding land use, contamination risk
- Cultivation practices — propagation material, fertilisation, pest control, irrigation
- Harvest timing and technique — peak phytochemical concentration, mechanical damage prevention
- Primary processing at origin — drying parameters, cleaning, grading, packaging
- Documentation — field records, harvest logs, grower training
GACP ends at the manufacturing-facility gate. From the moment material is received for extraction, you are out of GACP and into GMP.
GMP — Good Manufacturing Practice
GMP governs how the manufacturing facility operates. The relevant standards depend on the end-use: ICH Q7 for active pharmaceutical ingredients, EU GMP Part II for APIs, the FDA's 21 CFR 211 for drug products, and national equivalents for nutraceutical and food-grade material.
What GMP covers:
- Facility design — air handling, water systems, segregation of incompatible activities
- Equipment qualification — installation, operation, and performance verification
- Process validation — extraction methods documented and demonstrated repeatable
- Personnel — training, gowning, health monitoring
- Materials management — receipt, sampling, quarantine, release
- Documentation and batch records — every action on every batch, retained for years
The single most important thing to understand about GMP is that it is about the manufacturing system, not the product. A GMP-aligned facility is one whose systems are designed, documented, and audited to produce material of consistent quality. It is not, by itself, a claim about the quality of any specific batch.
HACCP — Hazard Analysis and Critical Control Points
HACCP is a risk-management framework, not a manufacturing standard. It originated in food safety (Codex Alimentarius) and is now a foundational requirement for ISO 22000 food-safety management systems.
What HACCP does:
- Identifies the biological, chemical, and physical hazards present in a specific process
- Determines the critical control points — the steps where a hazard can be eliminated, prevented, or reduced to an acceptable level
- Sets critical limits at each CCP
- Specifies monitoring procedures to verify limits are met
- Defines corrective actions when limits are breached
- Builds verification and record-keeping discipline around the whole system
For a botanical-extract manufacturer, the HACCP plan typically identifies microbial contamination, heavy metals, pesticide residue, mycotoxins, and solvent residue as the hazards, with CCPs at intake testing, extraction parameters, drying, and finished-extract release.
Where the boundaries sit
A useful way to keep these straight:
- GACP = what happens in the field, ending at the facility gate
- GMP = what happens inside the facility, from intake to release
- HACCP = the risk-analysis layer underneath both, naming the specific hazards and how they're controlled
The three frameworks are complementary, not redundant. A material that arrived at a GMP facility from a non-GACP source has a quality hole the GMP system cannot fill. A facility with strong GMP but no HACCP plan is operating without a documented hazard model — which usually means the gaps are wherever the auditors last didn't look.
"Aligned with" versus "certified to"
This is where botanical-ingredient marketing gets fuzziest. "GMP-aligned" or "GACP-aligned" usually means: the operator has adopted the framework's practices, documents to its standard, and is willing to be audited against it, but does not hold a formal certification from an accredited body. "Certified to ISO 22000" means a named certification body has audited the system and issued a certificate against the standard.
Neither is automatically better — alignment without certification is common in regions where the relevant certification bodies haven't yet built out their botanical-pharmaceutical capability, and it can still be substantively rigorous. But the language matters: a supplier saying "ISO 22000:2018 certified" is making a specific, verifiable claim. A supplier saying "GMP-aligned" is making a softer one, and the buyer should ask for the audit trail that backs it.
What we publish
Phyto-Medichem operates a GMP-aligned manufacturing facility with an ISO 22000:2018 certified food-safety management system, an active HACCP plan covering all extraction processes, and GACP-aligned sourcing through our grower partnerships. We can produce the documentation behind every one of those claims on request. If a supplier you're evaluating can't, that's the signal.
