QUALITY
100% LAB-TESTED
Every product on Cannabuben is batch-tested by SANAS-accredited independent labs. This page explains exactly what we test for and how to get the lab report for any SKU.
WHAT WE TEST
The four test tiers
CANNABINOID PROFILE
Every batch is tested for THC, CBD, CBG, CBN and CBC content using HPLC. The Certificate of Analysis lists exact mg-per-ml (oils) or mg-per-gram (flower), so you always know what you are actually taking.
MICROBIAL SAFETY
Total aerobic plate count, yeast, mould, and E. coli screening on every batch of consumable products. Failed batches do not reach the catalogue.
HEAVY METALS
Lead, cadmium, mercury and arsenic screened per batch. Important for any plant-derived product since cannabis is a bioaccumulator — it absorbs what the soil contains.
PESTICIDE RESIDUE
Multi-residue pesticide panel on a per-batch basis for cultivated cannabis and CBD. Products that fail the SA and international residue limits are destroyed.
WHY LAB-TESTING EVERY BATCH MATTERS
The gap between "tested" and "tested every batch"
A lot of South African CBD brands advertise "lab-tested" but quietly mean they tested one batch, once, years ago. Cannabinoid content drifts between batches. Pesticide exposure varies with harvest. Microbial safety depends on storage conditions that change with every season. Single-batch testing is a marketing move, not a quality guarantee.
We test every batch that arrives. When a batch fails — and occasionally they do — it doesn't reach the catalogue. When a batch passes, the COA goes on the product page alongside the batch number on your bottle. If the numbers don't match, something went wrong and we want to know about it.

COA ANATOMY
What you'll see on every report
Each Cannabuben COA follows the same structure. If you've read one, you've read them all.
- 1
Header · product + batch
The product SKU, the batch / lot number, the testing lab, and the date the sample was drawn. The batch number should match what is stamped on your bottle label.
- 2
Cannabinoid potency table
CBD, THC (Δ9 and sometimes Δ8), CBG, CBN, CBC listed as percentage or mg/g. For oils the mg/ml is derived. Legal compliance requires THC below the Schedule-0 trace; anything higher would route the product to the Rx pathway.
- 3
Pesticide residue screen
Multi-residue panel (30+ compounds). Each one lists PASS or the measured value against the action limit. A handful of micrograms is not uncommon; meaningful residues mean batch rejection.
- 4
Heavy metals
Lead, cadmium, mercury, arsenic. Cannabis is a bioaccumulator — the plant concentrates what's in the soil. Every batch gets screened independently of source reputation.
- 5
Microbial + mycotoxin
Total yeast and mould count, total aerobic, E. coli, Salmonella, aflatoxin. Flower products fail this more often than tinctures. Tinctures that fail suggest a hygiene issue upstream — we investigate before re-sourcing.
- 6
Residual solvents (extracts only)
Ethanol, hexane, butane. CO₂ and ethanol extractions should show zero to trace; hydrocarbon extractions require tighter limits. The COA lists each solvent explicitly.
