The sample is the starting point
Every laboratory result is only as representative as the sample behind it. When a seller selects and submits the sample, there is no way for a buyer to know whether it reflects ordinary inventory.
What independent purchasing changes
When a third party buys a product through the seller's normal checkout, without advance notice, the seller cannot prepare a special sample. The product arrives the same way it would for any customer.
- The buyer, not the seller, chooses the product.
- The buyer, not the seller, chooses the timing.
- The product goes from the ordinary order to the laboratory with a documented chain of custody.
What it still cannot do
Independent purchasing improves how representative a single sample is. It does not turn one result into a statement about every lot or every future order.
