Contact HiSiaddi customer service for further inquiries regarding EDC hydrochloride regulatory compliance.
The client is a top-tier French biopharmaceutical enterprise headquartered in Paris, specializing in high-end peptide drugs, ADCs and in vitro diagnostic reagent R&D and manufacturing, distributing products across major European and North American pharmaceutical markets under rigorous global compliance frameworks including EU REACH/CLP, US TSCA, cGMP and ISO 13485. A representative high-end Western buyer, the company procures approximately 250 kg of EDC hydrochloride (1-Ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride) annually for core drug synthesis condensation and protein conjugation workflows, with near-zero tolerance for compliance failures. Previous sourcing from domestic Chinese suppliers led to repeated customs clearance delays, cargo detention and production supply disruption due to incomplete compliance documentation and unqualified export certifications, prompting the client to commission HiSiaddi to manage full end-to-end procurement compliance for China-sourced material.
While shifting procurement to China to reduce costs, the client faced dual EU and US market compliance requirements, yet domestic manufacturers initially demonstrated weak compliance awareness, disorganized document systems and incomplete certifications, manifesting in four critical regulatory barriers:
EDC hydrochloride (CAS 25952-53-8, HS code 2925290090) is classified as Class 8 corrosive dangerous goods (UN 2735, Packing Group III). Domestic manufacturers frequently misdeclare it as general non-hazardous chemicals, omitting dangerous goods export filings, dual-use item verifications, dangerous goods packaging certificates and standardized GHS SDS documentation. This resulted in rejected customs declarations, cargo detention and fines or forfeiture penalties.
EU regulations mandate full REACH registration for chemicals with annual export volumes ≥1 ton, alongside CLP-compliant labeling, 16-section GHS-standard SDS and SVHC Substance of Very High Concern testing reports. Most domestic manufacturers lacked completed REACH registrations, issued non-GHS-compliant SDS and failed to affix EU hazard warning labels. Shipments arriving at EU ports were detained by customs, halting client production schedules.
US import rules require chemical substances to be listed on the TSCA Inventory, alongside CNAS-certified COA, DMF filings, endotoxin/microbiological testing reports and non-human-origin certificates. Domestic suppliers lacked TSCA Inventory registration, issued COAs without authoritative third-party laboratory accreditation and omitted biosafety compliance documentation, preventing clearance through US FDA and customs and blocking market access entirely.
As a premium pharmaceutical manufacturer, the client requires full batch production records (BPR), quality control records (QCR), raw material traceability reports and 12-month stability study data to satisfy EU EMA and US FDA audit requirements. Domestic manufacturers generally submitted incomplete, falsified or untraceable production data, exposing the client to severe regulatory compliance risks during internal and authority audits.
Specialized teams covering dangerous goods customs brokerage, EU REACH/CLP regulation, US TSCA compliance and pharmaceutical audit support were assembled to address the client’s dual-market regulatory requirements, delivering a full closed-loop compliance workflow: "Qualification Standardization → Document Completion → Registration & Certification → Customs Clearance Support → Audit Assistance", resolving every pain point systematically.
1. Accurate classification & filing: Confirmed EDC hydrochloride’s Class 8 UN 2735 corrosive hazard classification, assisted manufacturers in completing dangerous goods production/operation registrations and verified customs supervision conditions to eliminate misdeclaration risks.
2. Full dangerous goods document package coordination: Supported manufacturers in securing Transport Packaging Performance Inspection Certificates (dangerous goods packaging certificates), GHS-standard SDS and hazard classification appraisal reports to complete all mandatory customs filing materials.
3. Compliant specialized customs brokerage: Utilized dedicated dangerous goods declaration channels with full transparency on product name, HS code, UN number and hazard classification, achieving first-time customs release without rejection or detention.
1. REACH registration agency service: Appointed an EU Only Representative (OR) to complete annual REACH registration matching the client’s 250 kg import volume, obtaining official ECHA registration confirmation letters.
2. CLP compliance documentation drafting:
1. Compiled fully compliant 16-section GHS SDS detailing composition, hazard classification, protective measures and transportation information aligned with EU OSHA standards.
2. Designed CLP regulatory labels with mandatory GHS hazard pictograms (corrosion, irritation), UN number, hazard grade and manufacturer information to eliminate customs query risks.
3. SVHC testing & SCIP notification: Commissioned EU-accredited laboratories to conduct full 224-item SVHC testing and issue qualified compliance reports confirming no exceeding high-concern substances, meeting EU SCIP database notification obligations.
1. TSCA Inventory registration support: Assisted manufacturers in completing US EPA TSCA Inventory listing and securing official EPA registration confirmation letters for legal US market entry.
2. Full biosafety documentation package:
1. Delivered CNAS-stamped authoritative third-party COA verifying ≥99.8% purity, ≤0.15% moisture and ≤0.08 EU/mg endotoxin levels.
2. Supported manufacturers in DMF filing, compiling non-human-origin certificates, microbial limit testing reports and sterility test records to meet FDA biosafety requirements.
3. Regulatory import compliance statements: Signed official US import compliance declarations committing full adherence to TSCA and FDA regulations with no prohibited components, reducing customs inspection risks.
1. Standardized documentation structuring: Guided manufacturers to formalize batch production records (BPR) and quality control records (QCR), detailing full traceability across raw material procurement, synthesis workflows, in-process controls and finished product testing with verifiable, authentic data.
2. Supplementary critical technical datasets: Completed 12-month full stability study data, impurity profile analysis reports and complete raw material supply chain traceability documents to satisfy EMA and FDA audit requirements for full data integrity.
3. Mock audit & on-site audit support: Prepared mock audit Q&A libraries and standardized document review checklists, with HiSiaddi specialists accompanying client factory audits to resolve regulatory inquiries in real time, enabling one-shot internal audit approval.
Within two weeks, HiSiaddi finalized all registration, certification and documentation work, delivering a complete compliance package to the client categorized by jurisdiction:
1. Domestic China documentation: Dangerous goods packaging certificates, GHS SDS, hazard classification appraisal reports, customs declarations
2. EU documentation: REACH registration confirmation letters, CLP-compliant SDS, CLP hazard labels, SVHC test reports
3. US documentation: TSCA registration letters, CNAS-certified COA, DMF filings, full biosafety reports, import compliance statements
4. Audit support materials: Batch production records, quality control logs, full stability datasets, end-to-end traceability reports
The client submitted all materials to EU/US customs and FDA authorities with zero objections, achieving full regulatory clearance and permanently eliminating cargo detention risks.
The first 50 kg shipment of high-purity biological-grade EDC hydrochloride (≥99.8%) was shipped via dedicated dangerous goods cold chain transport. HiSiaddi tracked the full customs, ocean freight and cross-border clearance workflow, delivering materials to the French facility within 21 days without delay or detention. The shipment passed full incoming QC and compliance audits and was immediately deployed into production.
The client’s Compliance Director commented: "As a critical raw material, EDC hydrochloride’s regulatory compliance directly impacts our global supply chain security and market access. HiSiaddi’s team demonstrated exceptional professionalism, efficiency and rigor, fully resolving our four core compliance challenges and establishing a complete, auditable traceability regulatory framework fully aligned with top EU and US regulatory standards.
