About THREE-T

We make silicone test leads and DMM accessories. We do not make drinkware, baby products, or generic silicone gifts. If you saw leftover template copy on an older site, ignore it — that was CMS pollution, not the business.

What we will not print on this site

FDA, BSCI, or a blanket ISO claim until the certificate file, number, and scope sit in our archive. CE is listed only on SKUs that already carried it on the factory listing. IEC type names (YDTL, YDTP, YDTC, AMC) exist; we send the matching PDF, not a zip of “all certificates.”
