The cooperating client is ECO-BATT GmbH based in Bavaria, Germany, a leading domestic German R&D and manufacturing enterprise of power batteries specializing in high-end passenger vehicle power ternary lithium batteries and commercial stationary energy storage cells, whose products support the original power battery supply chains of Mercedes-Benz and BMW. It has long placed fixed orders for mid-to-high-end copolymer lithium-grade PVDF binders from Arkema and Solvay, exclusively purchasing vehicle lithium battery-specific PVDF powder and never adopting low-grade general PVDF for anti-corrosion coatings or water supply and drainage extrusion pipes. Full-chain production complies with four mandatory compliance standards: EU REACH Regulation, RoHS 2.0 Directive, SCIP Database Notification and Germany BAuA Chemical Filing. The enterprise’s annual global PVDF procurement volume exceeds 180 tons, ranking as a high-quality mid-to-high-end buyer in the fluororesin subdivision sector.
In 2025, affected by shrinking local European fluorochemical production capacity, extended delivery cycles of original imported PVDF exceeding 90 days and continuous 32% hikes in raw material quotations, the client launched localized alternative procurement of domestic PVDF. Recommended by the German Chemical Raw Materials Association, the client connected with HiSiaddi New Materials Foreign Trade based in Shanghai and finalized an initial trial order of 3.6 tons of copolymer lithium PVDF, planning to sign a long-term annual procurement framework of 42 tons after verification of compliance.
On the eve of shipment for the first batch of goods, multiple severe compliance defects emerged consecutively: the original factory supporting documents lacked REACH registration supplementary files, SVHC high-concern substance screening exceeded limits, full-item RoHS test reports were unavailable, MSDS safety data sheets only existed in simplified Chinese failing to meet German customs clearance specifications, and EU SCIP Database product notification could not be completed. German local importers notified that goods with incomplete compliance documents would be detained, returned or subject to heavy fines upon port arrival, forcing delays to the client’s scheduled production launch date. The client urgently fully entrusted HiSiaddi to coordinate full-process compliance rectification and complete all compliance formalities within a 18-day window for smooth customs clearance and shipment on schedule.
Note: Low-grade PVDF for coatings and pipes only requires basic customs declaration documents without mandatory REACH registration, SCIP notification or stringent heavy metal control. All compliance challenges in this case are exclusive mandatory requirements for mid-to-high-end lithium raw materials.
The supplying factory could only provide factory COA quality inspection sheets without corresponding REACH registration dossiers and downstream extended registration certificates. Initial SGS testing of 251 SVHC high-concern substances detected phthalate substances at 0.13% within PVDF powder introduced by trace additives, exceeding the EU REACH limit of 0.1%. Per EU regulations, shipments exceeding 1 ton with SVHC content above the limit cannot enter the EU market and must complete official ECHA notification. The original factory lacked corresponding rectification experience and could not rapidly adjust formulas to reduce SVHC content.
The client’s products are used for EU complete vehicle assembly, and PVDF lithium battery binders are categorized as upstream raw materials for electrical and electronic equipment, mandating compliance with ten hazardous substance control items under RoHS (lead, cadmium, mercury, hexavalent chromium, four phthalates, polybrominated flame retardants). The original manufacturer only tested conventional physical and chemical indicators without controlling trace heavy metal impurities. Testing detected cadmium content at 125 ppm exceeding the RoHS upper limit of 100 ppm, and no English RoHS test reports issued by EU-recognized laboratories were available, leading to direct rejection of raw materials during incoming audits by German vehicle manufacturers.
The original factory’s MSDS only existed in simplified Chinese without bilingual German and English versions. Safety data sheets failed to comply with EU GHS Globally Harmonized System of Classification and Labelling of Chemicals for compilation. Outer product packaging lacked compliant GHS hazard warning labels, ingredient markings and emergency contact information, leading to customs judgment of inconsistent documents during German customs commodity inspection and full-container detention for inspection.
Since 2021, the EU has mandated that all materials entering the EU market containing SVHC substances above 0.1% must log product information, material component details and supplier filing codes in the SCIP Database. Most domestic PVDF manufacturers lack familiarity with SCIP declaration rules and have never completed database filings. Goods without SCIP filing codes cannot be stored or distributed within Germany.
1. HiSiaddi coordinated manufacturers to fine-tune PVDF polymerization additive formulas by replacing phthalate processing additives exceeding limits, re-produce small-batch trial samples, and entrust EU-recognized SGS laboratories to retest full-item SVHC indicators. All substance contents fell below 0.08% after rectification, meeting REACH limit requirements and eliminating notification risks.
2. Leveraging HiSiaddi’s long-term cooperative EU REACH licensed agency, retrieve the EU main registration dossier for this PVDF grade, process downstream user extended registration certificates, issue Chinese-English REACH compliance statements clarifying product registration numbers, CAS substance codes and annual output filing information to satisfy dual audits by German customs and the client.
3. Sort and archive full REACH technical dossiers including component lists, brief toxicology reports and exposure scenario explanations for synchronized submission to the client’s German compliance department for filing.
Targeting excessive trace cadmium elements, HiSiaddi urged manufacturers to replace high-purity monomer raw materials, strictly control metal impurity introduction from equipment abrasion during production, and optimize finished product filtration and purification processes. Uniform sample delivery to dual CNAS + EU NL accredited laboratories completed full-item testing of ten hazardous substances in accordance with the latest RoHS 2.0 Directive. Final indicators confirmed lead ≤8 ppm, cadmium ≤22 ppm and all phthalates below control thresholds. Official English RoHS test certificates were issued for incoming compliance audits of vehicle manufacturers by the client.
1. HiSiaddi collaborated with EU compliance engineers to recompile German + English bilingual MSDS safety data sheets based on product components, strictly following EU REACH and GHS regulation clauses with detailed breakdown of storage and transportation risks, first-aid measures, waste disposal and EU regulation applicable clauses.
2. Custom unified compliant foreign trade outer packaging: aluminum foil vacuum inner bags + moisture-proof cartons printed with standard GHS hazard warning icons, product models, component proportions, EU emergency consultation telephones and manufacturer information, replacing original non-compliant simple packaging to avoid customs label inspection risks.
HiSiaddi connected with local German compliance service providers, sorted product hierarchy, material component details, SVHC substance specifications and Chinese and foreign supplier qualification documents, completed product filing and declaration in the EU ECHA-SCIP system, and obtained exclusive SCIP filing codes within 5 working days. Codes were marked on packing lists and invoices to satisfy legal filing requirements for domestic storage and distribution within Germany.
HiSiaddi confirmed the HS code for primary-form lithium-grade PVDF, standardized declaration of component proportions, uses, brand models and CAS numbers, and sorted unified customs declaration documents including commercial invoices, packing lists, certificates of origin and full-set compliance test reports. Coordinate customs brokers to pre-audit documents in advance and avoid export commodity inspection detention caused by misclassification or missing documents. Relying on the China-Germany Free Trade Agreement, standardize completion of origin documents to assist the client in enjoying preferential import tariff reductions within the EU.
1. Smooth customs clearance and commissioning of 3.6-ton trial order: All full-set compliance formalities were completed within 17 working days, and goods were shipped to Hamburg Port, Germany on schedule. Fast customs clearance without inspection was completed upon port arrival relying on REACH, RoHS and SCIP filing documents. After incoming warehouse entry, raw materials passed compliance internal audits of Mercedes-Benz and BMW supply chains, with 98.1% production line slurry yield and all electrochemical indicators benchmarked against original imported Arkema raw materials. The client completed new cell mass production scheduling smoothly, avoiding losses from delayed order compensation.
2. Signing of annual 42-ton procurement framework agreement: After dual verification of trial order compliance and product performance, ECO-BATT officially signed an annual procurement agreement with HiSiaddi, stipulating stable supply of a total of 42 tons of copolymer PVDF divided into 9 batches annually. HiSiaddi continues to provide annual synchronized renewal services including SVHC re-test reports, SCIP information maintenance and annual compliance file updates.
3. Industry resource referral expansion: Relying on German lithium battery industry resources, the client referred two additional local leading power battery enterprises based in Munich and Stuttgart to HiSiaddi for domestic PVDF compliance selection and procurement. HiSiaddi opened a stable supply channel for mid-to-high-end lithium PVDF in Germany relying on its one-stop compliance service capabilities.
The supplied products of this project are mid-to-high-end copolymer PVDF binders dedicated to EU vehicle power batteries, subject to strict mandatory constraints of multiple EU chemical and environmental bills throughout the full chain with cumbersome compliance systems and extremely high penalty costs for violations. Its compliance requirements are fundamentally distinct from low-grade PVDF for anti-corrosion and pipelines that only require simple customs declaration. Breaking the basic foreign trade model limited to supply-demand connection and delivery, HiSiaddi relied on professional chemical compliance capabilities to close a full-chain compliance loop covering formula rectification, third-party testing, EU registration, database declaration and customs clearance, resolving overseas mid-to-high-end clients’ cross-border regulatory barrier pain points. This serves as a typical implementation case of refined fluorochemical foreign trade achieving differentiated competitiveness through value-added compliance services.
