S-Chem AG, Switzerland, specializes in R&D and manufacturing of high-end microelectronics, liquid crystal materials, and supporting photoresist solvents, with end products supplied to leading European panel and automotive chip manufacturers. The company purchases 90 tons of high-purity electronic grade CHP annually for high-end liquid crystal stripping solutions and microelectronics precision cleaners, previously relying on EU domestic imported raw materials. To cut production costs, the customer launched domestic procurement from China. After independently sourcing two domestic CHP manufacturers and completing payment preparation, a chain of five interconnected compliance failures emerged prior to shipment: domestic export customs clearance, ocean hazardous chemical declaration, EU REACH customs clearance, CLP label compliance, and SVHC substance control. Domestic raw material manufacturers could only provide COA quality inspection certificates without capabilities in international chemical compliance drafting, hazardous chemical export filing, and EU regulation coordination. SDS and product labels issued by factories failed to comply with current EU regulations, exposing goods to risks of blocked domestic export customs clearance, detention and return by EU customs upon arrival, and heavy fines. The customer urgently entrusted HiSiaddi with full responsibility for closed-loop rectification of full-chain compliance.
CHP, CAS: 6837-24-7, classified as Class 6.1 toxic hazardous goods under GHS with UN2810 Group III packaging, subject to dual strict regulation of China’s hazardous chemical supervision and EU REACH/CLP.
The factory’s original English SDS adopted outdated versions, failing to comply with mandatory 16-chapter content under EU Regulation 2020/878 REACH Annex II, lacking exposure scenario descriptions, SVHC component screening, and EU local importer liability clauses. ECHA regulations mandate importers to complete entry notification via compliant SDS; the existing documents were deemed invalid by Swiss customs brokers, guaranteeing cargo detention upon arrival in Europe.
Original factory packaging only bore simple Chinese marks, missing GHS hazard pictograms, signal word “Danger”, UN numbers, precautionary statements, and EU chemical classification codes. These labels failed both China Customs’ hazardous chemical export inspection requirements and EU CLP landing label specifications, rendering all drum labels invalid and preventing container loading and shipment.
Domestic manufacturers failed to apply for hazardous chemical classification identification reports, hazardous goods packaging performance certificates, hazardous goods packaging use appraisal certificates, and hazardous chemical compliance declarations. Per General Administration of Customs Announcement No. 129 of 2020, Class 6.1 hazardous goods without the above documents are prohibited from customs clearance. Ordinary freight forwarders refused hazardous goods booking for this shipment, leaving cargo stranded in factory warehouses unable to exit.
Pre-inspection by the customer’s third-party laboratory revealed trace by-product components in factory batches of CHP suspected to fall under the EU’s latest SVHC Substances of Very High Concern list, with content approaching the 0.1% control threshold. Exceedance would ban the entire batch from production, circulation, and sales within EU territories.
Leveraging its fine chemical compliance database and third-party testing resources, HiSiaddi delivered closed-loop rectification across two segments: domestic export compliance and EU market access compliance, completing full-process formalities within 12 working days.
1. Rewrite bilingual Chinese-English compliant SDS in accordance with latest REACH regulations, completing all mandatory items across 16 chapters, supplementing SVHC screening data, hazardous chemical transportation emergency information, and EU importer filing information. A condensed German SDS for Switzerland was issued concurrently for local customs clearance;
2. Draft Chinese SDS exclusively for China Customs declaration to meet consistency verification requirements of domestic commodity inspection and customs documents.
Redesign full drum labels per GHS + CLP regulations, marking UN2810, Class 6.1 toxicity pictograms, hazard statements H302/H331, and precautionary phrases. HiSiaddi arranged on-site label replacement at a nearby factory for all batches of 200L iron drums, satisfying both domestic export inspection and European port landing inspection standards.
1. Coordinate authoritative domestic testing institutions to urgently issue CHP hazard characteristic classification identification reports, confirming Class 6.1 toxic hazardous goods and Group III packaging;
2. Assist packaging manufacturers in supplementary UN hazardous goods packaging performance testing to obtain Exit Hazardous Goods Packaging Performance Certificates and Hazardous Goods Packaging Use Appraisal Certificates, complete hazardous chemical enterprise compliance declarations, and file electronic customs ledgers for full documents before vessel schedules to pass commodity inspection smoothly;
3. Coordinate compliant hazardous goods freight forwarders to complete maritime hazard declarations, full-container hazardous goods booking, and arrange dedicated hazardous goods trucks for container loading.
HiSiaddi coordinated SGS laboratories to conduct precise quantitative testing of suspected SVHC components, confirming measured substance content below the EU 0.1% limit. Authoritative third-party test reports were attached to customs clearance documents to eliminate EU customs detention risks. A raw material incoming SVHC sampling inspection standard was established for the customer to conduct pre-screening of every subsequent batch.
1. Hand over complete compliance archives to the customer: compliant SDS, CLP label drafts, full set of hazardous goods customs clearance documents, SGS impurity test reports, and COA;
2. Notify the customer of annual EU REACH regulation update timelines and SVHC list change early warning mechanisms to avoid compliance pitfalls for future new product procurement.
1. Cargo originally at risk of detention was cleared customs and shipped on schedule. Upon arrival, complete compliant documents enabled one-time Swiss customs clearance without detention or fines, with raw materials delivered to production facilities smoothly;
2. Machine testing of this batch of CHP confirmed qualified performance, leading to the signing of an annual 90-ton quarterly phased procurement framework;
3. All subsequent domestic CHP procurement by the customer fully entrust HiSiaddi with pre-compliance audits to eliminate regulatory risks at the source, abandoning independent manufacturer coordination for compliance processing;
4. The customer prioritizes HiSiaddi for full-process compliance control for subsequent procurement of derivative pyrrolidone series products.
1. Core pain point of high-end overseas fine chemical customers: Domestic manufacturers focus solely on production, generally lacking capabilities in international chemical regulations, easily triggering non-compliance of documents, labels, and testing leading to cargo detention, return, substantial cargo losses, and delivery breach penalties;
2. Core value of HiSiaddi: Connect full chains of domestic hazardous chemical export compliance and EU REACH/CLP market access compliance, conduct pre-screening of hidden compliance risks such as SVHC, and supplement full sets of legal documents in one stop, bridging compliance gaps of production manufacturers via trade service channels;
3. Differentiating advantage: Distinct from ordinary traders only engaged in sales without regulatory expertise, HiSiaddi builds risk control barriers for mid-to-high-end customers via its compliance system, forming core value-added capabilities for high-end chemical foreign trade.
