The cooperating client is SWISS BUILD AG, a high-end Swiss building materials group focusing on eco-friendly sealing and coating systems for high-end residential buildings, luxury hotels and passive houses across the Alpine region, covering high-net-worth markets in Switzerland, Germany and Austria. It adheres to full-spectrum compliance standards including EU REACH, France A+, EN 15651 and SVHC Substances of Very High Concern lists, representing a top-tier European mid-to-high-end client.
The client places an annual order of approximately 45 tons of zero VOC modified silane for high-end curtain wall structural sealing, indoor eco-coating modification and prefabricated building bonding. Core compliance requirements include measured zero VOC values, full-ingredient REACH registration, non-detection of all 241 SVHC substances, France A+ certification, CLP-compliant labels and English SDS/TDS documents. The client long purchased European brands including Wacker (Germany) and SABA (Netherlands), and launched its first Chinese supply chain in 2025 by selecting a domestic zero VOC modified silane manufacturer. However, pre-shipment third-party preliminary inspection identified multiple critical compliance defects, risking cargo detention at customs and project shutdown. The client urgently entrusted HiSiaddi with full compliance rectification and document supplementation.
1. Critical REACH Non-Compliance
· Core raw materials lacked formal REACH registration; only a declaration of conformity was provided without official ECHA registration certificates;
· A trace phthalate plasticizer contained in one formula additive exceeded the EU 0.1% limit under REACH Annex XVII restricted substances;
· No REACH supply chain transmission documents were provided, guaranteeing customs detention in Switzerland.
1. Misleading Environmental Certifications
· The manufacturer claimed "zero VOC", yet third-party testing recorded VOC=12g/L, only qualifying as "low VOC" and failing the EU zero VOC threshold (≤1g/L);
· The France A+ certificate was the outdated 2019 version, incompatible with the latest 2025 EU EN 16516 testing standards;
· No EN 15651 CE certification for construction sealants, disqualifying products for EU high-end curtain wall projects.
1. Non-Conforming SDS/TDS & CLP Labels
· Only incomplete 16-section Chinese SDS was provided without English versions, violating EU GHS/CLP regulations;
· TDS omitted critical data including measured VOC values, SVHC screening results and aging resistance indicators, failing the client’s Swiss technical audit;
· Product labels lacked CLP hazard pictograms, UN numbers and ingredient CAS numbers, prohibiting sales within the EU market.
1. Invalid Third-Party Test Reports
· Testing institutions lacked CNAS/EUROFINS accreditation, rendering reports unrecognized by EU authorities;
· Reports failed to cover mandatory testing items including all 241 SVHC substances, VOC release levels and heavy metal migration;
· Reports exceeded the 18-month validity period, violating EU annual review requirements.
HiSiaddi immediately assembled a special team of compliance experts, formula engineers and certification specialists, activating a 48-hour emergency compliance audit and 7-day rectification delivery mechanism to comprehensively resolve issues across four dimensions: formula compliance optimization, certification supplementation, standardized documentation and label rectification.
1. Formula Compliance Optimization to Eliminate Restricted Substances
· Full ingredient screening: All 23 raw materials in the formula underwent comprehensive testing for 241 SVHC substances, phthalates and heavy metals in cooperation with EUROFINS laboratories to locate restricted additives;
· Formula fine-tuning: Phthalate-containing additives were replaced with EU-compliant eco-friendly dispersants; emulsification systems were adjusted to reduce measured VOC from 12g/L to 0g/L for genuine zero VOC performance;
· Compliance verification: Post-rectification testing confirmed non-detection of all SVHC substances, VOC=0 and heavy metal levels ≤0.1ppm, fully meeting top-tier EU environmental standards.
1. Supplement Full-Spectrum EU Certifications to Secure Market Access
· REACH Registration: Domestic raw material suppliers coordinated formal REACH registration of core substances to obtain official ECHA registration certificates; REACH supply chain transmission letters were issued clarifying tonnage and compliance liabilities;
· France A+ Upgrade: VOC release testing was conducted under the latest EN 16516 standards to acquire a 2025-version France A+ certificate (highest environmental grade);
· CE Certification (EN 15651): CE certification for construction sealants was completed with a Declaration of Performance (DoP) issued, enabling deployment on EU high-end curtain wall projects;
· RoHS/REACH Declarations of Conformity: Official stamped English declarations were issued to formalize compliance commitments.
1. Compile Standard English SDS/TDS Compliant with GHS/CLP
· Safety Data Sheet (SDS): A complete 16-section English SDS was drafted in accordance with REACH Annex II 2023 standards, covering physical and chemical properties, toxicology, ecotoxicology, transportation and REACH/SVHC information, reviewed and stamped by an EU-recognized institution;
· Technical Data Sheet (TDS): Critical indicators including measured VOC values, SVHC screening results, aging resistance, elasticity and bonding strength were supplemented, with documents supplied in English, French and German;
· Compliance Document Package: Certification certificates, test reports, SDS/TDS and declarations of conformity were compiled into an English compliance handbook for client filing and audit convenience.
1.
Rectify CLP Labels to Meet EU Market Requirements English labels were designed in compliance with CLP Regulation (EC 1272/2008), including product name, CAS numbers, ingredient composition, net weight, manufacturer information, REACH registration numbers, A+ and CE logos, GHS signal words, safety statements, batch numbers and expiry dates. Waterproof weather-resistant label materials were selected to satisfy EU warehousing and transportation standards.

Endorsement by Authoritative Third-Party Testing Full-project test reports were issued by EUROFINS, a leading EU testing institution, covering zero VOC performance, non-detection of all 241 SVHC substances, France A+ compliance and EN 15651 performance indicators. Reports carry dual CNAS/EUROFINS accreditation seals, fully recognized by Swiss customs and the client.

Full Compliance Approval & Smooth Customs Clearance Post-rectification products passed Swiss customs clearance without detention or fines. Third-party retesting confirmed VOC=0, negative SVHC results, valid A+ certification and CE compliance, fully satisfying requirements for Switzerland’s high-end building material projects. Products were successfully deployed for curtain wall sealing at luxury Alpine hotels and passed environmental acceptance inspections.
