HiSiaddi is an innovative foreign trade service provider driven by dual business pillars: technology commercialization and international trade. We operate under a "1+2+3+4=1" service system and can supply dipropylene glycol dimethyl ether (DMM) sourced directly from multiple well-known original manufacturers. As a tech-driven foreign trade enterprise with over a decade of market experience, HiSiaddi has accumulated rich expertise in product compliance through manufacturer technology conversion cooperation. Below is a case detailing HiSiaddi’s resolution of DMM compliance issues.
Contact HiSiaddi customer service for inquiries about DMM product compliance issues.
NORCHEM AB, headquartered in Stockholm, Sweden, is a local Swedish high-end fine chemical R&D enterprise with 32 years of expertise in high-performance eco-friendly industrial cleaners, lithium battery electrolyte additives, and special resin solvent R&D. Its products supply leading Nordic new energy manufacturers and precision optical coating factories. The client historically purchased original European and American dipropylene glycol dimethyl ether. Faced with rising overseas raw material prices and extended delivery lead times, the client selected two high-purity grades previously recommended by HiSiaddi: Yida DMM-998 and Yida DMM-EH, with an annual total procurement volume of 92 tons shipped in four sea freight batches to Gothenburg Port, Sweden.
The client only completed physical and chemical testing of raw material samples in advance without coordinating compliance rules between China and the EU. Original manufacturer documents were drafted solely per domestic Chinese national standards. When goods were ready for shipment, four compliance bottlenecks emerged covering EU import access, Chinese export customs clearance, CLP labeling, and SVHC Substance of Very High Concern screening. Freight forwarders notified the client that incomplete documentation would either block customs clearance for export from China or result in cargo detention, full-container return, or destruction upon arrival at the EU port. The client’s Swedish compliance department suspended payment and delayed shipments, fully entrusting HiSiaddi to coordinate full-process compliance rectification.
Dipropylene glycol dimethyl ether imported into the EU in annual volumes exceeding 1 ton requires formal REACH registration. Domestic manufacturers only conduct domestic quality inspections without REACH registration dossiers, ECHA registration numbers, or appointed EU local Only Representatives (OR). Swedish local importers lack technical capacity for compliance declaration. New EU regulations ban entry of goods without valid registration numbers, with immediate detention upon port arrival incurring high detention and destruction costs.
Manufacturers issue Chinese-language SDS drafted solely per domestic GB standards, lacking EU CLP classification, German/Swedish hazard statements, toxicological and environmental data, and SVHC screening content. Multiple gaps exist across the 16 mandatory SDS sections, failing both domestic customs hazardous goods declaration requirements and Swedish Chemicals Agency port clearance review standards. Shipping lines rejected booking requests due to non-compliant SDS.
Barrel outer packaging only featured Chinese product names and specifications, missing mandatory CLP legal content including GHS hazard pictograms, EU hazard signal words, EU representative manufacturer addresses, product CAS numbers, and precautionary statements. EU customs would detain goods immediately upon identifying non-compliant labels as regulatory violations.
The 2026 EU SVHC candidate list covers 251 controlled substances. As the client’s products are used in high-end new energy formulations, the Swedish compliance department enforces mandatory submission of full-component SVHC test reports for raw materials. Any substance detected above 0.1% concentration requires notification in the EU SCIP database. Domestic manufacturers only conduct purity testing without third-party CNAS laboratory full-item SVHC screening reports, preventing client warehousing, production, and local supply chain filing.
Additional domestic export barriers: Manufacturers failed to issue hazard classification identification reports and outbound packaging certification documents, rendering customs hazardous goods export declaration impossible and detaining full containers at factory warehouses.
HiSiaddi assembled a special task force consisting of EU compliance specialists, chemical customs declaration specialists, and third-party testing coordinators to implement closed-loop rectification across five dimensions: EU import compliance, document revision, label rectification, testing filing, and domestic export customs clearance. All rectification work was completed within 12 working days.
1. HiSiaddi coordinated with EU certified compliance institutions to leverage existing REACH pre-registration dossiers for dipropylene glycol dimethyl ether using physical and chemical data from domestic manufacturers, activating existing substance registration numbers to avoid months of delays from re-registration.
2. Assist manufacturers in contracting a Swedish local compliance firm as the EU Only Representative (OR), complete enterprise and product information filing in the ECHA system, and issue official OR appointment documents and REACH registration certificates for archiving by the Swedish client’s compliance department to meet EU statutory pre-import requirements.
1. Redraft trilingual (Chinese, English, Swedish) Safety Data Sheets in accordance with UN GHS and EU CLP (EC 1272/2008) regulations, supplementing toxicological data, environmental hazard data, CLP hazard classification, SVHC entries, and OR representative information to fully complete all 16 mandatory SDS sections.
2. Separate two document sets: Chinese-language SDS for domestic customs export declaration and shipping line booking; Swedish-language original SDS accompanying goods for Gothenburg port clearance and client warehouse compliance review.
Customize compliant self-adhesive labels aligned with Swedish regulations listing product CAS numbers, GHS flammability hazard pictograms, hazard H-statements, precautionary P-statements, EU OR enterprise addresses, and UN transport numbers. All 200L iron drums across the full container were re-labeled, with label samples retained for customs and Swedish commodity inspection filing.
1. Engage a CNAS-accredited third-party testing laboratory to conduct full 251-item SVHC screening testing for both Yida DMM grades, issuing authoritative bilingual Chinese-English COA test reports. All controlled substances were detected far below the 0.1% limit, eliminating restricted control requirements.
2. Assist the Swedish client in pre-notifying product information in the EU SCIP database to generate official notification codes, fulfilling mandatory supply chain filing requirements for Nordic new energy industries.
1. Coordinate manufacturers to submit samples for testing to obtain chemical hazard classification identification reports, outbound goods packaging performance certificates, and packaging use appraisal documents, issuing hazardous goods export compliance statements for Hohhot Customs of the People’s Republic of China.
2. HiSiaddi handled pre-export commodity inspection and customs pre-declaration, proactively identifying risks in declaration elements and HS code classification to lock in customs clearance approval.
1. Full closed-loop compliance implementation: All REACH, CLP, SVHC, and customs documentation passed audits, shipping lines released booking space normally, and goods were loaded and shipped on schedule.
2. Zero abnormal clearance at destination port: Goods arrived at Gothenburg Port, with Swedish Customs rapidly verifying full compliance documentation without physical inspection or detention, completing release and warehousing within three working days.
3. Client mass production launch: After compliance filing, the two DMM grades were successfully applied to cleaner and electrolyte additive mass production, with finished products passing incoming material audits by leading Nordic new energy manufacturers.
4. Full framework order fulfillment: All four batches of the 92-ton annual framework contract were delivered smoothly, eliminating client deduction risks.
5. Long-term compliance service established: HiSiaddi created a dedicated product compliance file for the client, conducting pre-review of REACH and SVHC requirements for all new raw material purchases annually to proactively mitigate compliance risks from the source.
1. Core pain point of overseas mid-to-high-end clients: Domestic manufacturers focus solely on physical and chemical product quality and generally lack awareness of EU regulations, only capable of providing national standard documentation incompatible with strict EU import access rules. Overseas high-end enterprises are bound by local legislation to reject goods without compliant documentation, while small-scale traders lack capacity to coordinate cross-border regulatory rectification across two jurisdictions.
2. Differentiated compliance value of HiSiaddi: Connect full-chain regulations covering domestic export customs clearance and EU REACH/CLP/SCIP rules, proactively predicting bidirectional China-EU compliance risks, and delivering one-stop full-process implementation of registration, testing, labeling, and documentation to resolve regulatory barriers – the most intractable challenge for high-end clients.
3. Core competitiveness of high-end chemical foreign trade: Beyond product selection and technical services, full-process compliance risk mitigation is the key to securing long-term cooperation with European and American mid-to-high-end clients.
