FAQ

About these notes.

Who writes them, what we will not publish, and how to reuse them in your own sourcing docs.

All questions
Who actually writes these articles?
The people who run the line — process engineers, QC leads and the sampling team. Every article carries a byline and the test method behind each number, so you can check the claim instead of trusting the tone.
Can we republish or translate an article?
Yes, with attribution and a link back. Please do not edit the test figures — if a number needs localising (mm to inch, for example), ask us and we will send the converted version.
Will you review a competitor bottle we already bought?
We will read a lab report or a failed inspection with you and explain what the numbers mean. We do not publish teardowns of named competitors — that is a different business.
Can an article become a spec sheet for our SKU?
That is usually why they exist. Send the capacity and channel and we will turn the relevant article into a costed spec sheet with the test clauses already written into the purchase order.

Have a question we have not written about?

Ask an engineer directly. If it is a good question, it usually becomes the next article.
