I\u2019ve seen plants lose contracts over material compliance oversights. The tubing that touches your product isn\u2019t just a piece of rubber\u2014it\u2019s a critical safety barrier. And for thermoplastic polyurethane (TPU) tubing, not all \u201cfood-grade\u201d labels are created equal.&lt;\/p&gt;\n&lt;p style='line-height: 2.25em;font-size: 15px;color: rgb(62, 62, 62);text-align: left;text-indent: 0.5em;margin: 1em 0px;visibility: visible;'&gt;Let\u2019s break down the certifications that actually hold weight, why they matter for your specific line, and how to audit your current setup without getting lost in marketing fluff.&lt;\/p&gt;\n&lt;h2 style='font-size:18px;font-weight:bold;line-height: 20px;color:#000;padding-left: 10px;margin-bottom:10px;margin-top:10px'&gt;1.

This regulation sets limits on extractable substances\u2014meaning the material can\u2019t leach toxic monomers into your milk or juice.&lt;\/p&gt;\n&lt;p style='line-height: 2.25em;font-size: 15px;color: rgb(62, 62, 62);text-align: left;text-indent: 0.5em;margin: 1em 0px;visibility: visible;'&gt;&lt;strong&gt;Here\u2019s the catch:&lt;\/strong&gt; Passing this test once doesn\u2019t mean the tubing is safe for every food type. Acidic beverages (pH &lt; 4.5) and high-fat dairy products interact differently with polymers. A tube that\u2019s safe for water may fail fat-extraction tests.&lt;\/p&gt;\n&lt;p style='line-height: 2.25em;font-size: 15px;color: rgb(62, 62, 62);text-align: left;text-indent: 0.5em;margin: 1em 0px;visibility: visible;'&gt;&lt;strong&gt;Action step:&lt;\/strong&gt; Demand a certificate of compliance (CoC) from your supplier that explicitly lists your product type\u2014not a generic \u201cfood contact\u201d statement. Test three batches from different production runs. I\u2019ve seen inconsistent batches where one passes and the next doesn\u2019t.&lt;\/p&gt;\n&lt;h2 style='font-size:18px;font-weight:bold;line-height: 20px;color:#000;padding-left: 10px;margin-bottom:10px;margin-top:10px'&gt;2.

Then you\u2019re under &lt;strong&gt;Regulation (EU) No 10\/2011&lt;\/strong&gt; on plastic materials and articles intended to come into contact with food. This is more stringent than FDA in one key area: &lt;strong&gt;overall migration limits (OML) of 10 mg\/dm\u00b2&lt;\/strong&gt; and specific migration limits (SML) for individual substances like plasticizers and stabilizers.&lt;\/p&gt;\n&lt;p style='line-height: 2.25em;font-size: 15px;color: rgb(62, 62, 62);text-align: left;text-indent: 0.5em;margin: 1em 0px;visibility: visible;'&gt;For dairy specifically, EU rules test with &lt;strong&gt;simulant D1 (50% ethanol)&lt;\/strong&gt; for fatty foods and &lt;strong&gt;simulant B (3% acetic acid)&lt;\/strong&gt; for acidic beverages. A TPU tube that passes FDA\u2019s water-based tests might fail EU\u2019s ethanol test because TPU can absorb fats.&lt;\/p&gt;\n&lt;p style='line-height: 2.25em;font-size: 15px;color: rgb(62, 62, 62);text-align: left;text-indent: 0.5em;margin: 1em 0px;visibility: visible;'&gt;&lt;strong&gt;Real-world example:&lt;\/strong&gt; In 2023, a German dairy cooperative rejected a shipment of TPU tubing from a Chinese supplier because the migration into whole milk exceeded 8 mg\/dm\u00b2\u2014well within FDA limits but over the EU\u2019s stricter 10 mg\/dm\u00b2 when adjusted for milk\u2019s fat content.&lt;\/p&gt;\n&lt;p style='line-height: 2.25em;font-size: 15px;color: rgb(62, 62, 62);text-align: left;text-indent: 0.5em;margin: 1em 0px;visibility: visible;'&gt;&lt;strong&gt;Action step:&lt;\/strong&gt; If you export, require EU Declaration of Compliance (DoC) and request the actual migration test report\u2014not just a self-declaration.
