Our manufacturing process ensures that:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Lead (Pb) &amp; Arsenic (As):<\/strong> Levels are maintained at \u2264 2 mg\/kg and \u2264 3 mg\/kg respectively, meeting the safety thresholds required for the US market.<\/li>\n\n\n\n<li><strong>Identity Testing:<\/strong> Our products pass the infrared absorption and solubility tests defined in the FCC monographs, confirming they are chemically identical to domestically produced US additives.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3.
