Practical sourcing knowledge for brand owners and procurement teams — how to judge documentation, read a quote, and buy wholesale with confidence. No jargon, no filler.
How to read a Certificate of Analysis
A COA is a lab report for a specific production lot — not a marketing document. Four things to check before anything else:
- Lot number and date. The COA must match the lot you are actually buying. A COA for last year’s batch tells you about last year’s batch.
- Identity and potency. The assay should name the exact compound and the tested percentage — “ashwagandha extract, withanolides 5.2% (HPLC)” — and it should meet the specification the listing claims.
- Contaminant panels. Heavy metals (lead, arsenic, cadmium, mercury), microbiology, and where relevant pesticides and solvents, each with the limit alongside the result.
- Who tested it. A named laboratory and method carries more weight than an unattributed table. Third-party results outrank in-house ones.
On Remibee, sellers attach COAs directly to listings and the “Valid COA on file” chip shows at a glance — look for it while browsing.
MOQs and wholesale unit economics
The headline price per kilogram is only half a quote. The minimum order quantity decides what a listing really costs to try: €9/kg with a 500 kg minimum is a €4,500 commitment, while €12/kg at 100 kg lets you validate a product for €1,200 before scaling. Cheaper per unit is not always cheaper.
Factor in lead time the same way. A lower price with a ten-week lead time can cost more than the premium alternative once you count the stock-outs it causes. Every Remibee listing states price per unit, MOQ and lead time together so quotes compare like for like — and listings below a minimum order value of €100 don’t go live at all, because trades that small don’t survive shipping and documentation costs.
Certification glossary
What the badges on listings actually attest:
- GMP — the facility follows Good Manufacturing Practice: controlled processes, hygiene, batch records, recalls. The baseline for anything you put in a product.
- ISO 22716 — GMP specifically for cosmetics manufacturing.
- Organic — certified grown and processed without prohibited pesticides or synthetic inputs, audited through the supply chain.
- Vegan — no animal-derived ingredients or processing aids.
- Halal / Kosher — production audited against Islamic or Jewish dietary law; opens retail channels that require it.
- Non-GMO — ingredients verified free of genetically modified organisms.
Certifications belong to facilities and lots, not to brands — which is why Remibee shows them on the listing even though the seller is anonymous. Browse by certification to filter for the ones your channel requires.
How anonymous RFQs keep pricing honest
When you ask for a price by email, the seller knows your brand, guesses your budget, and quotes accordingly. When sellers can see each other’s offers, prices cluster instead of competing.
A Remibee request removes both distortions. You post the spec — quantity, target specification, certifications, destination — and every supplier who can fill it quotes blind: they see the requirement, not your identity, and never a rival’s number. You compare the results side by side and accept the best one; identities are only introduced once a deal is agreed and funds are held. Post your first request — it’s free, and so is receiving quotes.
