Checking Lots on a Wholesale Delivery
BacWaterPep trade note · revised
In brief. When a wholesale delivery arrives, check three records against each other: the lot numbers on the cartons, the packing list and the certificate of analysis (COA) of each lot. Then compare the expiry with the shelf life you agreed, inspect the vials, and raise any claim soon after delivery with photos.
| Lot match | Carton label = packing list = COA |
|---|---|
| Benzyl alcohol | Measured % v/v inside 0.8–1.0% (our specification: 0.9% ± 0.1%) |
| pH | Measured value inside 5.0–7.0 |
| Sterility and endotoxins | Results reported with their methods |
| Expiry | At least the minimum shelf life stated in your quote |
Step 1 — Lot by lot
A COA speaks for one lot only. Every lot number on a carton should appear on the packing list and have its certificate; a lot without one is a question for the sales desk before the stock reaches the shelf.
Step 2 — Read the numbers
Quantitative tests — benzyl alcohol, pH, endotoxins, fill volume, particulate matter — should show the measured value beside the limit, not only 'conforms'.
Step 3 — Inspect the goods
- Cartons intact, kits complete, the count matching the packing list.
- Vials clear and colourless, without particles.
- Expiry dates matching the COA and your agreed minimum shelf life.
Step 4 — Claims
Raise a claim soon after delivery, with photos of the cartons, kits and vials. Transit damage, short shipments and wrong items are reshipped; a quality nonconformance is refunded in full, as agreed with our sales team.
