OEKO-TEX & REACH Compliance: Sourcing Eco-Friendly Metal Buttons for Global Brands

August 20, 2026 141

OEKO-TEX certification and REACH regulation often get lumped together in sourcing conversations, but they are two completely different systems — one checks whether the finished product is clean, the other governs what chemicals a factory uses along the way. Global brands sourcing eco-friendly metal buttons do not choose between the two. They stack them, then layer material-side and process-side environmental requirements on top. At Songji, across 27 years of metal button manufacturing, almost every international brand we have served treats this environmental standard as the first barrier to procurement.


I. The Difference Between OEKO-TEX Certification and REACH for Metal Buttons


OEKO-TEX is voluntary certification that tests finished-product residue — formaldehyde, azo dyes, heavy metals, phthalates and more than 1,000 other substances in total, divided into 4 classes by wearing position, with Class I covering children under 3 and carrying the strictest limits.


REACH is mandatory EU regulation. It does not test finished-product residue. It governs the full lifecycle of chemical substances — registration, evaluation, authorisation and restriction. Its most direct requirement for metal buttons sits in the Annex XVII restriction list, covering limits on lead, cadmium and nickel release.


The relationship in one sentence: OEKO-TEX answers "is this button clean," and REACH answers "what chemicals went into this button." Global brands do not rely on either alone. REACH is the legal red line — meeting it is the baseline for entering the EU market. OEKO-TEX is market trust — with it, a buyer can place an order without hesitation. Brands in the baby and child product space feel this most sharply. Clients like NUNA pushchairs and BMW child safety seats treat OEKO-TEX Class I as a hard requirement, no grey area. Songji holds both: products meet REACH requirements, and the factory holds OEKO-TEX Standard 100 Class I certification.

II. What to Look for on the Material Side of Eco-Friendly Metal Buttons


The starting point of an eco-friendly metal button is the material. Lead-free and nickel-free are hard requirements — lead comes from impurities in cheap copper alloy, nickel from the electroplating process, and both can cause problems on skin contact, especially for infants and sensitive skin.


Material choice also ties to brand positioning. For LEE, Songji customised denim buttons in high-strength brass. For GAP, the choice was zinc alloy. Different materials, but the same environmental standard applies to both. Songji's material-side approach is to screen at the source: every batch of copper and alloy arrives with a material certificate, and anything exceeding Songji's own heavy metal limit of 40PPM is rejected on the spot — a figure tighter than the OEKO-TEX Class I lead limit of 45PPM.


On recycled material, Songji holds GRS certification, covering a traceable supply chain for recycled materials. For brands with sustainable sourcing requirements, this is a hard reference when selecting suppliers — it means environmental commitment is not a slogan but a verifiable action traceable to specific batches and materials.

III. What to Look for on the Process Side of Eco-Friendly Metal Buttons


Clean material is not enough if the production process creates new pollution. The biggest environmental problem in traditional electroplating is cyanide — cyanide-based plating produces wastewater and exhaust that are costly and polluting to treat. The industry's direction over recent years has been a shift to cyanide-free plating.


Songji uses cyanide-free plating with a wastewater treatment system to control discharge, and holds HIGG FEM environmental performance assessment at the certification level. For global brands, a supplier's environmental process is not a bonus but a barrier to entry — an ESG review drills straight down to the plating step, and green manufacturing is part of a sustainable procurement chain.


IV. Market Compliance Focus for Global Brands Sourcing Metal Buttons


The same metal button faces different hurdles in different markets. The EU market runs a dual check of REACH regulation plus OEKO-TEX certification. The US market looks to CPSIA, especially for children's products under 12, with separate limits on lead and phthalates.


High-end brands demand stricter multi-market compliance. The brands Songji serves, including Burberry and PORTS, run product lines across multiple markets, so a single button must simultaneously satisfy regulations in different regions — this requires a supplier with a unified standard that covers all of them. Songji's approach is one standard covering multiple markets: products meet REACH, and OEKO-TEX is held at Class I, the strictest level, meaning infant-grade safety effectively covers the compliance requirements of every market. When supplying LEE, GAP and Carter's, these compliance configurations are the precondition of the partnership, not something up for negotiation.

V. A Sourcing Checklist for Dual-Certified Eco-Friendly Metal Buttons


When sourcing eco-friendly metal buttons, run through these 5 items before placing an order.

  1. Which OEKO-TEX class is it? Childrenswear requires Class I, adult outerwear can use Class II — do not let a lower-class certificate pass for a higher-class use.

  2. How is REACH compliance proven? Is it a verbal claim or backed by corresponding test data?

  3. Is there a self-imposed heavy metal standard? What is the specific value, and how much stricter is it than the regulatory limit?

  4. Is there a recycled-material certification such as GRS? If you have sustainable sourcing requirements, this determines whether the supplier makes the list.

  5. Is the electroplating cyanide-free? Will it pass environmental acceptance and ESG review?


Run through these 5 items and the gap between a metal button factory that genuinely embeds environmental practice at both the material and process ends, and a trading company that only waves a certificate, becomes clear. Songji has passed 72 international brand audits over the past 10 years, with environmental compliance and document traceability as mandatory items every time.


Songji Buttons was founded in 1999, has focused on metal buttons for 27 years, operates a 12,000 m² production base in Shenzhen with close to 700 machines, holds OEKO-TEX Standard 100 Class I, GRS and ISO 9001 certifications, has passed 72 international brand audits over the past 10 years, and supplies custom metal buttons to brands including LEE, GAP and Carter's.
