Specifications
Common specifications are listed for reference. If you need a different specification, send us your target parameters and we will match them from the manufacturers we buy from.
Certificates
We can provide the certificate type, the products covered and the validity period on request. Certificate copies are not published on this website, and we do not display certificate images or logos.
What we do not claim
- We do not claim to be a manufacturer or to operate a production plant.
- We do not publish certification marks for certificates we cannot evidence.
- We do not describe testing as laboratory-accredited unless the documentation we hold shows it.
- We do not publish prices on this website; pricing depends on specification, quantity and delivery terms.
Why the specification sheet matters
A specification sheet carries a version number and an effective date, and it is the document we work from when we confirm a product's parameters. A batch COA records what was measured on one batch; it is not a specification and it is not a commitment for future batches.
