When a peroxide order arrives, check that the product, concentration, container size and count match your order, then record the lot code. Those details make a missing-item question or a later document request much easier to resolve.
This is a purchase and recordkeeping checklist for an ordinary, intact delivery—not a spill-response procedure. If a package is leaking, visibly damaged or otherwise suspicious, do not open or handle it just to complete the checklist. Keep others away and follow the product’s emergency instructions and your workplace’s trained response process, if applicable.
1. Compare the delivery with the order confirmation
Read the item description on your confirmation and the labels on the containers. Check:
- The product name and concentration.
- The stated size of each container.
- The number of containers in each pack.
- The number of packs ordered and delivered.
A four-pack is one order item but four bottles. Two four-packs should account for eight bottles, unless part of the order is arriving separately. Check tracking and any partial-shipment notice before concluding that something is missing. The bottle-size and pack guide explains how to read pack quantities.
2. Keep the three different codes straight
| Code | What it connects to | When it helps |
|---|---|---|
| Order number | Your purchase | Finding the transaction or delivery |
| Product code or SKU | The item sold | Confirming the product and package option |
| Lot or batch code | A particular batch of material | Requesting the corresponding batch certificate |
Do not assume the order number is the lot number. Also, several containers in one shipment do not necessarily all have the same lot. Record the codes as printed. If you cannot tell which code identifies the batch, ask the supplier.
3. Save a small, useful record
You do not need an elaborate spreadsheet for a small order. Keep the confirmation with the delivery date, the received quantity and the lot codes. If you need to report a discrepancy, a safely obtained photograph of the readable label can prevent a long exchange about what arrived.
Record an expiration, retest or manufacture date only if one is actually printed or supplied. Do not treat those different date types as interchangeable or invent an expiration date from the delivery date.
For a workplace with its own receiving system, use that system rather than creating a competing record.
4. Match any required documents to the shipment
An SDS explains hazards and precautions; a COA reports batch-specific analytical information. If you need a COA, check that its product and lot correspond to the material received. A sample certificate on a website may show the format without covering your shipment.
You do not need to interpret every analytical result while counting boxes. Keep document matching separate from the more detailed review of specifications and COA results. Our SDS vs. COA guide explains what each document provides.
If something does not match, send a specific question
Here is a hypothetical message for an intact delivery with a quantity discrepancy:
My order [order number] lists one four-pack of 32 fl oz bottles. I received three bottles on [date], and tracking does not show a second package. The product labels read
. Can you confirm whether another bottle is on the way or help resolve the missing item?

For a document question, replace the quantity details with the product and lot code, and name the document you need. Send order details privately through the supplier’s support channel, not in a public review or comment. Bulk Peroxide customers can use our contact page.
If the product itself does not match the order, resolve that before using it. A clear record helps the supplier investigate; it does not replace the label or safety instructions.
