Does Food-Grade Silicone Tubing Pass RoHS and REACH Testing?

Genuine food-grade and medical-grade silicone is formulated to meet both standards, and reputable manufacturers test for them as a matter of routine. The catch is that compliance lives in the formulation and the test report, not in a marketing line on a web page. So the real task isn't hoping the tubing passes. It's confirming it with a declaration and a lab report you can hand to your own auditor.

These two regulations get mentioned together so often that people assume they're the same. They're not.

RoHS is the EU's Restriction of Hazardous Substances rule. It limits a short list of dangerous materials in products, including lead, mercury, cadmium, hexavalent chromium, certain brominated flame retardants, and some phthalates. The aim is to keep those substances out of goods sold in Europe.

REACH is the EU's broader chemical safety regulation. Its heart is the Candidate List of Substances of Very High Concern, or SVHCs, which now runs to more than 240 chemicals and is updated twice a year. If any SVHC is present in an article above 0.1% by weight, the maker has to disclose it.

The base material works in your favor. The silicone polymer itself, PDMS, isn't on the SVHC list, and the platinum-cured process used for food and medical tubing doesn't rely on the tin catalysts or restricted additives that trip up cheaper materials. Clean formulation plus clean cure usually means clean compliance.

This is the part a careful supplier will raise before you do:

· Cyclic siloxanes D4 and D5 are on the SVHC list, and they exist as trace residues in silicone polymer. In many silicone articles their combined level sits close to the 0.1% disclosure threshold, so a proper SVHC declaration is worth requesting rather than assuming.

· Pigments and fillers in colored tubing can introduce restricted heavy metals if the formulation is careless.

· Catalyst residues, especially certain organotin compounds in cheaper cure systems, can raise REACH flags.

None of these are reasons to avoid silicone. They're reasons to buy from a maker who documents what's in the material.

Don't accept a claim. Ask for evidence:

1. A RoHS Declaration of Conformity (DoC) that names the product and the directive it meets.

2. A REACH/SVHC declaration confirming whether any SVHC sits above the 0.1% threshold, with details if it does.

3. A third-party lab report, using XRF or ICP-MS to screen for restricted metals and GC-MS for organic substances.

4. Food-contact certificates alongside them, such as FDA 21 CFR 177.2600, LFGB, or NSF 51, depending on your market.

If a supplier can produce these quickly, you're dealing with a real manufacturer. If they only offer reassurance, keep looking.

RoHS vs. REACH at a Glance

When compliance really matters, the grade of silicone does too. Medical-grade material is higher in purity and is typically platinum-cured, often available to USP Class VI standards on top of FDA and food-contact certifications. Pair that purity with a braided wall for pressure handling and you get Medical Grade Silicone Tubing Reinforced, which carries both the documentation and the durability that regulated industries need. For everyday food work where the rules are lighter, a well-documented Food Grade Reinforced Silicone Tubing or a standard Silicone Food Hose still clears RoHS and REACH at a friendlier price, as long as the paperwork comes with it.

A [medical device / food export] customer in [region] had a shipment delayed because a previous supplier couldn't produce an SVHC declaration on request. They moved to sunhingstones for a compliant, reinforced line.

We supplied the full set up front: RoHS Declaration of Conformity, a REACH SVHC declaration, and third-party lab reports. The customer cleared [customs / their factory audit] without a hitch and now sources their regulated lines from us. (sunhingstones tubing was recognized at [ESTA / industry event] for [award or standout feature], a reflection of our focus on documented, traceable compliance.)
