Verified Quality Through Comprehensive Testing and Documentation
Quality assurance begins with cultivation partnerships and extends through extraction, testing and export. We control production in-house and verify every batch against established specifications before release. Our documentation supports procurement qualification, regulatory compliance and formulation confidence.
Analytical Testing Standards
Each batch undergoes gas chromatography-mass spectrometry (GC/MS) analysis to verify compositional profile and menthol content. Physical-chemical parameters including specific gravity, optical rotation and refractive index confirm material identity and purity. Sensory evaluation by trained assessors ensures aroma consistency batch-to-batch.
Safety & Compliance Screening
Pesticide residue testing covers compounds relevant to mint cultivation regions. Heavy metals screening verifies absence of contamination. Microbial testing establishes aerobic plate counts, yeast, mold and pathogen limits appropriate to intended use. Solvent residue analysis confirms extraction process integrity.
Certificate of Analysis (COA) Access
Every shipment includes batch-specific COA documentation with complete analytical results. Redacted COA previews available during procurement assessment to verify our testing scope and parameter limits. Full COA provided with material delivery and retained for traceability and audit support.
Regulatory Documentation
Food-grade certifications for food and beverage applications. Cosmetic compliance documentation for personal care use. Pharmacopeial certificates for pharmaceutical-grade rectified material. Material Safety Data Sheets (MSDS) and technical data sheets available for all grades.
Quality System Alignment
Our manufacturing operations follow Good Manufacturing Practice (GMP) principles. Batch records, processing documentation and chain-of-custody tracking support customer quality systems and regulatory audits. We maintain validated analytical methods and participate in proficiency testing programs to ensure measurement accuracy.
Supplier Transparency
We provide cultivation region information, extraction method details and processing facility documentation to support supply chain transparency requirements. Traceability extends from grower partnerships through final packaging and export.
Quality verification is not an add-on service—it is integrated into our production process and documented at every stage. When you specify Rubicha material, you receive both the product and the proof of quality that procurement and regulatory teams require.
