HEMEI
Quality & Certifications

What we hold, and what belongs to our materials.

We separate the two on purpose. Our company holds an ISO 9001:2015 quality system. Some test reports cover the raw material we buy in — not our finished tube — and we say so plainly. No blanket "fully certified" claims.

Test reports on the raw material we use

These reports were commissioned by our TPU resin supplier and cover the raw material — the PU pellets — not Hemei's finished tube. We show them so you can see the quality of what goes in, described honestly for what they are.

All four documents above: commissioned by the resin supplier (MIRACLL) · subject: TPU pellets, model E190LU · material-level, not a finished-tube certification.

Why we draw this line. A material test report is not the same as a finished-product certification, and treating them as equal would mislead you. If your application needs finished-tube testing to a specific standard — food contact, potable water, a named flame or chemical standard — tell us and we'll arrange the right test rather than point at a supplier's report. Copies of any report above are available on request.
Need documentation?

Ask for the certificate or report you need.

We'll send the ISO certificate, material reports, or arrange finished-product testing for your specification.
