Please contact HiSiaddi customer service if you require consulting on compliance issues related to 3-glycidoxypropyltrimethoxysilane.
SwissCompo Advanced Materials, a leading European manufacturer of mid-to-high-end new energy composite materials and automotive epoxy structural adhesives headquartered in Switzerland, supplies ABB new energy inverters and lightweight component manufacturers for European vehicle OEMs. All raw materials comply with full sets of EU regulations including REACH, CLP and RoHS, with an annual KH-560 procurement volume of 152 tons requiring strict refined material standards. After sample verification, the client finalized bulk procurement of domestically high-purity KH-560. When the first batch of 32 tons of goods was ready for booking shipping space, four critical compliance obstacles emerged one after another. Domestic manufacturers can only provide national standard quality inspection certificates without capabilities to prepare documents complying with EU import regulations. The client’s scheduled delivery deadline was approaching; failure to clear goods on time would result in compensation claims for breach of downstream vehicle OEM orders. The client urgently entrusted HiSiaddi with full authority to implement full-process compliance rectification and complete supplementary documentation. Four core compliance bottlenecks:
1. Non-compliant SDS safety data sheets: Factory self-made MSDS adopt old domestic national standard formats with only 10 sections, failing to meet the 16-section preparation requirements of EU GHS+CLP regulations. Hazard classification errors and missing UN shipping numbers led shipping companies to reject booking applications, and EU entry customs authorities refused recognition;
2. Incomplete REACH compliance: Annual import volume exceeds 1 ton, lacking an EU Only Representative (OR), no screening reports covering the 253 SVHC substances on the 2026 ECHA list, and no supporting ECHA registration documents from manufacturers. EU customs explicitly prohibit entry without compliant reports;
3. Risk of restricted substance excess under Annex XVII: Pre-testing by third-party laboratories revealed trace epichlorohydrin and free methanol impurity levels exceeding EU restriction thresholds under REACH Annex XVII. Port inspection non-compliance would result in direct full-batch return and high detention fines;
4. Non-compliant packaging and labels: Outer drum packaging lacks mandatory EU hazard pictograms, warning statements and ingredient markings required by CLP regulations, failing to meet EU mandatory standards for imported dangerous goods packaging labels.
Most domestic silane manufacturers focus solely on product production and sales, lacking reserves for EU import regulations. They can only adjust product indicators but cannot complete full sets of cross-border import compliance documents in one stop, leaving the client with no viable solutions after multi-party inquiries.
Leveraging chemical compliance resources and local EU partner institutions, HiSiaddi resolved issues in four phases: raw material indicator optimization, compliance document preparation, EU territorial filing and packaging standardization.
HiSiaddi coordinated cooperative high-end silane manufacturers to adjust rectification processes and upgrade three-stage molecular distillation purification lines for targeted deep removal of epichlorohydrin, residual methanol and trace halogen impurities. After rectification, finished products contain epichlorohydrin <12ppm and free methanol ≤0.12%, with all restricted substance levels below REACH Annex XVII control thresholds. Meanwhile, CNAS-accredited third-party laboratories issued full-item SGS test reports as supporting compliance evidence documents.
Cooperating with local EU compliance engineers, a full 16-section English SDS was newly compiled in accordance with the latest EU regulations, accurately marking KH-560 hazard classification, UN1993 shipping code, storage & transportation protection, spill emergency response and ecotoxicity data to correct original classification errors. Supporting EU-format dangerous goods transportation identification documents were issued simultaneously, passing shipping company document reviews and securing ocean booking confirmations.
1. Coordinate EU compliance institutions to assign formal EU Only Representatives (OR) for the client and complete annual import information filing for KH-560 substances;
2. Conduct full-component screening against the latest 253 SVHC substance list released by ECHA in 2026 and issue authoritative SVHC test reports, with all single substances of very high concern below the 0.1% limit. REACH Declaration of Conformity (DoC) was issued simultaneously to fulfill mandatory EU import declaration requirements and complete the full compliance dossier required for customs clearance.
Redesign drum labels in compliance with EU CLP regulations, printing flammable liquid hazard pictograms, English hazard warning statements, product CAS numbers, ingredient contents, manufacturer and EU representative address information. The factory replaced all batches with compliant packaging to meet inspection specifications at EU entry ports.
1. First batch delivery: After full review of all compliance documents, the 32 tons of KH-560 were loaded on schedule for shipment to Switzerland via Rotterdam transshipment. Port customs verified all documents in a single pass without cargo detention or inspection objections, enabling timely warehousing and production to help the client fulfill downstream vehicle OEM supply contracts and avoid breach compensation losses.
2. Annual order signing: Confirming the reliability of HiSiaddi’s compliance services, the client finalized a full-year 152-ton annual procurement order split into five separate shipments. HiSiaddi conducts pre-review of compliance documents and pre-test filing for each subsequent batch to realize normalized rapid customs clearance.
1. Industry Pain Points: Mid-to-high-end domestic silane manufacturers focus on product manufacturing and generally lack reserves for EU import regulations. They can only control physical and chemical indicators of raw materials but cannot support cross-border compliance systems including REACH, CLP and SDS. Mid-to-high-end overseas new material enterprises are bound by stringent EU environmental regulations; non-compliance will block entry even if product performance meets standards, easily leading to order suspension and cargo return losses.
2. HiSiaddi’s Core Value: Build a one-stop compliance closed loop covering "raw material indicator optimization + compliance testing + EU territorial filing + document preparation + packaging standardization", making up for compliance shortcomings of domestic manufacturers and eliminating cross-border access risks for high-end overseas clients, establishing HiSiaddi as the client’s exclusive procurement service provider in China.
3. Long-term Business Expansion: In the following year, the client entrusted HiSiaddi with exclusive agency for procurement, compliance and customs clearance services for four other types of special silanes including amino silane and vinyl silane. Supported by this compliance case, HiSiaddi developed three additional European high-end composite material clients in Finland and Luxembourg.
