EU POPs (Persistent Organic Pollutants)

What it is: An EU regulation that bans or strictly restricts the production, use and presence of persistent organic pollutants, which are chemical substances that don't break down in the environment, accumulate in living organisms and travel long distances through air and water.

Why you're receiving this request: POPs requests are increasingly common as the regulated substance list expands. Some POPs are pesticides, industrial chemicals, or

unintentional by-products formed during industrial processes. If your products contain any of these substances, or if you use industrial processes that generate them as by-products, your customer needs documentation. Because POPs persist in the environment and can be transported internationally, risk management occurs across borders, which is why EU-bound supply chains take this seriously regardless of where manufacturing occurs. The list of regulated substances is updated periodically in alignment with the Stockholm Convention, so a substance that wasn't on it two years ago may be now.
