As a new-type foreign trade service provider driven by both technology transformation and export business, HiSiaddi has established a service system of "1+2+3+4=1", capable of supplying original factory goods of dipropylene glycol dibenzoate from multiple well-known brands. With over a decade of market experience supported by technological cooperation with manufacturers, HiSiaddi holds extensive experience addressing product compliance issues. Below is a case handled by HiSiaddi regarding compliance problems of dipropylene glycol dibenzoate.
Please contact HiSiaddi customer service for more consultation on compliance issues of dipropylene glycol dibenzoate products.
Located in the Fine Chemical Industrial Park of Zurich, Switzerland, this mid-to-high-end Swiss coating terminal brand manufacturer (not a trading middleman) has 28 years of R&D and production experience in high-end food-contact infant wood coatings, medical equipment protective coatings and indoor low-odor eco-friendly coatings. Its full product range is sold to high-end infant homeware and medical device manufacturers in Switzerland and Austria, with mandatory raw material access requirements covering full EU REACH registration, full SVHC screening ≤0.1%, EU Regulation 10/2011 food contact migration certification, Swiss VOC environmental decrees and EU chemical SDS compliance. The enterprise consumes 55 tons of dipropylene glycol dibenzoate (DPDB) annually, previously sourcing additives locally from Switzerland. Faced with successive price hikes of European chemical raw materials and tight production capacity, the customer launched a procurement project for domestically manufactured DPDB imported from China. After independently negotiating with two domestic DPDB manufacturers, an initial batch of 22 tons was prepared for shipment. Pre-shipment compliance document inspection revealed multiple severe compliance flaws, risking inability to deliver goods, port detention upon arrival and customs clearance failure. The customer urgently entrusted HiSiaddi with full-process compliance rectification.
Domestic manufacturers only provided national standard quality inspection certificates, lacking complete EU entry compliance documentation:
1. REACH Compliance Gaps: No EU Only Representative (OR) registration & incomplete DPDB REACH pre-registration EU regulations mandate that chemical imports must complete REACH registration filing via an EU-local enterprise acting as Only Representative. Neither of the two domestic DPDB manufacturers completed pre-registration of DPDB (CAS: 27138-31-4) under REACH with EU OR filing documents. Swiss customs explicitly stipulate goods lacking registration materials will be detained, returned and subject to fines upon arrival.
2. Non-Compliant SVHC Test Reports: Testing institutions without EU recognized qualifications & incomplete impurity screening items In-house third-party testing conducted by manufacturers only screened 120 SVHC substances, failing full testing against ECHA’s latest 251-item SVHC candidate list. Laboratories issuing reports lack recognition by EU customs. Trace phthalate impurities remain in raw material refining residues, with partial component test values approaching the 0.1% legal control threshold, violating REACH candidate substance management requirements.
3. Blank Food Compliance Documentation: Absence of EU 10/2011 food contact migration test reports The customer’s products are applied to infant furniture paint films contacting food, requiring compliance with EU standards for food-contact plastics and additives. The two domestic manufacturers only issued national standard physical and chemical COA certificates without test data on food contact migration dissolution, failing admission standards of Swiss food and drug regulatory authorities.
4. Dual Non-Compliance of SDS Chemical Safety Data Sheets & Customs Classification ① Manufacturers prepared SDS documents following outdated domestic national standard formats inconsistent with EU GHS Version 6 regulations. Component labeling, toxicity descriptions and storage-transport warnings fail entry declaration requirements in Switzerland; ② Incorrect filling of declaration elements for DPDB customs code (2916310090) by domestic manufacturers with confusing labeling of composition, purity and application purpose, triggering inspection risks for both domestic export commodity inspection and Swiss import customs declaration.
Domestic manufacturers only deliver production and supply services without supporting EU compliance capacity, merely promising adjustment of product indicators yet unable to handle EU registration, overseas testing and document rectification. Replacing manufacturers and rescheduling production would delay commissioning of three coating production lines and trigger breach of contract penalties for downstream homeware orders. Therefore, the customer fully entrusted HiSiaddi with one-stop full-chain compliance rectification.
HiSiaddi formed four specialized teams consisting of EU compliance specialists, chemical testing coordinators, customs classification specialists and SDS compilation engineers, implementing a closed-loop five-step process covering product adjustment, qualification supplementation, retesting, document standardization and customs clearance planning.
1. HiSiaddi coordinated licensed Belgian REACH service providers to complete DPDB REACH pre-registration filing, supplement EC number records, substance composition dossiers and production process archives;
2. Assisted the customer in appointing a Swiss local chemical enterprise as the product’s EU Only Representative (OR), completing dual filing of enterprise and product information on the ECHA European Chemicals Agency system and obtaining official reply documents to eliminate entry registration barriers.
1. Coordinated domestic manufacturers to fine-tune distillation processes and upgrade two-stage molecular distillation purification to control trace phthalate impurities in raw materials, stabilizing all SVHC controlled substances below 0.03%, far below the EU legal limit of 0.1%;
2. Commissioned SGS laboratories recognized by the EU to conduct full testing against ECHA’s current 251-item SVHC list, alongside food contact migration dissolution tests complying with EU Regulation 10/2011. Bilingual Chinese-English official test reports recognized by all EU customs authorities were issued with traceable report numbers on the official SGS website, meeting dual audit requirements of Swiss food and drug regulatory authorities and customs.
The original domestic MSDS documents from manufacturers were discarded. HiSiaddi recompiled 16-module standard English SDS documents complying with EU CLP and GHS Version 6 regulations based on measured component data of DPDB, detailing chemical composition, toxicological data, storage-transport conditions, waste disposal and labeling of EU control clauses. Simplified German versions for Switzerland were supplemented simultaneously for local production filing and customs declaration.
1. Based on tariff provisions of HS code 2916310090, customs classification specialists re-standardized customs declaration elements: accurate labeling of CAS number, purity ≥99.2%, application (plasticizer additive for eco-friendly coatings) and detailed composition, completing pre-classification confirmation with customs to avoid domestic export inspection control risks;
2. Unified consistent Chinese and English wording of product names, specifications and cargo values across commercial invoices, packing lists and sales contracts with three-level document review to ensure fully consistent data across domestic outbound commodity inspection, ocean bills of lading and Swiss import declarations.
1. Sample Retesting (7 Working Days) After process adjustment by manufacturers, samples were delivered to SGS for SVHC and food migration testing, with all indicators meeting EU regulations and formal compliance certification issued.
2. Archiving of Full Set of Compliance Documents (12 Days) A complete compliance dossier was compiled including REACH pre-registration reply, OR representative filing documents, dual-item test reports, new GHS SDS documents and customs pre-classification opinions.
3. Customs Declaration & Shipment of 22-Ton Full Batch Goods With the full set of compliance documents, domestic outbound commodity inspection and customs clearance were completed smoothly. Goods were shipped by sea to Zurich Port, Switzerland. Swiss customs reviewed the complete compliance dossier, test reports and REACH filing information for one-time seamless customs clearance without port detention, fines or return shipment, with raw materials delivered directly to the customer’s factory warehouse.
4. Production Verification in Workshops The customer’s three production lines for infant coatings completed batch feeding and production, with finished products passing all local Swiss food contact and environmental testing for on-time delivery of downstream high-end homeware orders.
1. Signed Long-Term Annual Procurement Framework for 55 Tons Relying on HiSiaddi’s full compliance supporting capacity, the customer locked the domestically manufactured DPDB brand with six balanced monthly shipments per year. Comprehensive procurement costs decreased by 27.8% compared with original Swiss imported raw materials.
2. Full-Category Additive Compliance Custody For future procurement of film-forming additives and eco-friendly thickeners, the customer entrusted HiSiaddi with pre-entry compliance pre-audit to avoid subsequent compliance risks.
3. Upgraded Compliance Standards of Upstream Manufacturers Supported by compliance standards set for this Swiss high-end customer, the cooperative DPDB manufacturer improved internal product purification control standards. With HiSiaddi’s assistance, full REACH pre-registration qualifications were completed for all product grades, enabling successful expansion of business to two other EU high-end coating manufacturers in Austria and Luxembourg.
1. Most domestic DPDB manufacturers specialize in product production yet lack awareness of EU chemical regulations, only capable of controlling national standard product indicators without supporting cross-border compliance services covering REACH, SVHC and food-grade requirements. High-end infant and medical coating clients in Europe face severe risks of compliance deadlocks and cargo detention losses when purchasing domestic additives under strict EU environmental regulations.
2. Core Value of HiSiaddi: Establish a full closed-loop compliance service covering product process optimization → international authoritative testing → EU regulatory registration → compliance document compilation → domestic and overseas customs clearance, filling the compliance service gap between raw material manufacturers and high-end overseas end-users, serving as an indispensable third-party guarantee for high-end foreign clients purchasing domestically manufactured raw materials.
3. For procurement of DPDB in high-end markets including Europe, America and Switzerland, compliance documents carry equal importance alongside product quality. One-stop compliance services constitute core competitiveness distinguishing HiSiaddi from ordinary spot trading companies.
