The client is BEAUTYTECH PARIS, a premium French cosmetic raw material enterprise specializing in natural skincare raw materials, high-end color cosmetic additives and organic cosmetic intermediates, with products supplied to top international beauty groups including L’Oréal and Guerlain. For this procurement, high-purity TMDD (99.5%+) is purchased as a wetting and foam-suppressing additive for waterborne skincare emulsions, requiring compliance with EU REACH, food-contact grade (FCM), cosmetic safety standards (CosIng), complete English compliance documents, GHS labels and direct eligibility for EU customs clearance.
This was the client’s first procurement of TMDD from China, with limited familiarity with Chinese export customs clearance, EU REACH registration, SDS compilation, GHS labeling and food-grade certification requirements. Multiple contacted manufacturers failed to supply full sets of compliance documents, provided EU-noncompliant SDS and lacked FCM certifications, creating risks of customs detention, cargo return and production delays upon arrival at European ports. The client urgently entrusted HiSiaddi to resolve full-link compliance issues and guarantee smooth customs clearance.
1.
Missing EU REACH compliance: No registration records and non-compliant SDS The client required TMDD to complete REACH registration (annual output ≥1 ton), alongside 16-chapter English SDS complying with REACH Annex II and CLP regulations. Manufacturer-provided SDS only contained 12 chapters, were primarily Chinese-language, lacked EC numbers and SVHC declarations, and featured incorrect hazard classifications, failing EU customs clearance standards.
2.
3.
Blank food-contact grade (FCM) certifications: Missing compliance reports limiting cosmetic application The client’s products are used in lip care and food-contact color cosmetics, mandating TMDD compliance with EU FCM 1935/2004 and US FDA 21 CFR food-contact testing standards. Manufacturers had not conducted FCM certification and only supplied general industrial-grade COAs, unable to verify raw material eligibility for food-contact applications and violating EU cosmetic safety regulations.
4.
5.
Non-compliant GHS labels and packaging: Missing EU standard markings with high transportation risks EU regulations mandate GHS-standard labels on chemical packaging containing hazard pictograms, H/P codes, CAS numbers, EC numbers and 24-hour emergency contact numbers. Manufacturers only affixed simple Chinese labels lacking GHS pictograms and English text, with non-leakproof packaging failing EU transportation and warehousing specifications.
6.
7.
Incomplete Chinese export customs clearance documents: Ambiguous classification and missing regulatory certificates TMDD falls under HS code 2905399090, requiring accurate commodity classification, non-dangerous goods certificates, MSDS, COAs and standard commercial documents (contracts, invoices, packing lists). Manufacturers provided ambiguous commodity classification, lacked non-dangerous goods identification reports and only issued Chinese COAs, creating risks of customs inspection and cargo detention.
8.
HiSiaddi assembled a dedicated team of REACH compliance specialists, cosmetic regulatory experts, customs brokers and third-party testing coordinators, adopting a five-step solution of "Compliance Diagnosis → Document Completion → Certification Application → Label & Packaging Rectification → Customs Clearance Implementation" to finish all compliance rectifications within 7 days and enable smooth cargo clearance.
1. REACH diagnosis: Confirm TMDD holds valid REACH registration (ECHA Registration No.: 01-2119471899-26), yet manufacturer SDS contained format errors, missing data and outdated 2025 250-item SVHC lists;
2. FCM diagnosis: Manufacturers had not completed FCM 1935/2004 and FDA 21 CFR testing, requiring supplementary screening for heavy metals, migration levels and toxic hazardous substances;
3. Label & packaging diagnosis: Existing labels lacked GHS pictograms, English text and EC numbers; packaging lacked UN certification and leakproof structures;
4. Customs clearance document diagnosis: Correct HS code classification (2905399090), with missing non-dangerous goods identification reports and English COAs/SDS versions.
1. Rewrite 16-chapter English SDS strictly aligned with REACH Annex II and CLP Regulation (EC 1272/2008), supplementing EC No. (203-973-5), CAS No. (126-86-3), SVHC statements (no substances of very high concern detected) and 24-hour EU emergency hotlines, passing ECHA format validation;
2. Supply REACH registration certificates and registration dossier summaries coordinated with manufacturers to prove legal circulation eligibility of TMDD within the EU;
3. Update SVHC screening reports via SGS testing, issuing 2025 250-item SVHC screening certificates with non-detection results fully compliant with EU regulations.
1. Defined testing standards aligned with client requirements: EU FCM 1935/2004 (plastic food contact materials) and US FDA 21 CFR 175.105 (food-contact additives);
2. Sample submission: Coordinate manufacturers to supply 99.7% high-purity TMDD samples for testing at SGS Shanghai laboratory, covering lead, cadmium, mercury, arsenic, hexavalent chromium, migration levels, formaldehyde and heavy metal leaching indicators;
3. Compliance report issuance: Acquire dual English-language FCM + FDA certification reports within 3 days with all indicators passing inspection, directly applicable to food-contact cosmetic products.
1. Design EU-standard GHS labels containing English product name, CAS number, EC number, purity, hazard pictograms (no hazards), H codes (none), P codes (P264, P280), manufacturer information and EU emergency hotlines, printed in waterproof, oil-resistant English ink;
2. Packaging upgrade rectification: Replace with UN-certified 25kg food-grade plastic drums with thickened anti-drop barrel bodies and leakproof sealing gaskets, complying with international sea/air non-dangerous goods packaging standards;
3. Supplementary shipping markings: Affix additional English labels of "Non-Dangerous Goods", "Moisture-Proof Storage" and "Light-Resistant Storage" on drum surfaces to avoid transportation delays.
1. Apply for non-dangerous goods identification reports issued by the China National Chemical Research Institute, certifying TMDD as non-hazardous chemicals eligible for general cargo transportation;
2. Coordinate manufacturers to issue English factory inspection COAs with consistent purity, impurity, moisture and chromaticity test data matching SDS content;
3. Collate full sets of customs clearance documents: customs declaration forms, contracts, invoices, packing lists, non-dangerous goods identification reports, bilingual SDS, English COAs, FCM + FDA certification reports, ensuring consistency across all documents and certificates.
1.
Document review and confirmation HiSiaddi submitted the full set of compliance documents (SDS, REACH certificates, FCM + FDA reports, GHS label samples, customs clearance documents) to the client for review, receiving 100% compliance confirmation with no revisions requested.
2.
3.
On-site manufacturer rectification and inspection HiSiaddi engineers supervised label application and packaging rectification on-site at the manufacturer, conducting physical inspection to verify clear labeling, intact packaging and zero leakage risks complying with EU standards.
4.
5.
Export customs clearance and logistics HiSiaddi acted as export customs broker, passing customs review in one round with no inspection or detention; Maersk sea freight was arranged with full logistics tracking, arriving at Le Havre Port, France within 7 days.
6.
7.
EU customs clearance support HiSiaddi provided full English compliance documents to the client’s customs agent, enabling instant release upon passing EU customs inspection with no objections. Cargo was delivered to the client’s factory with fully qualified acceptance and zero quality defects.
8.
1. Complete elimination of the four core compliance challenges
· REACH compliance: EU-standard 16-chapter English SDS, REACH registration certificates and SVHC reports obtained, fully complying with EU regulations;
· Food-grade compliance: Dual FCM 1935/2004 + FDA 21 CFR certification reports acquired, enabling safe application in food-contact cosmetic products;
· Label and packaging compliance: EU-standard English GHS labels + UN-certified food-grade packaging meeting EU transportation and warehousing specifications;
· Customs clearance compliance: Full sets of supporting documents and non-dangerous goods identification enabling fast Chinese customs release with zero detention.
1.
Restored client production and on-time order delivery Cargo arrived at the factory without delays or returns, avoiding additional costs. The client successfully mass-produced premium lip care emulsions, passed EU cosmetic safety certification and delivered L’Oréal orders on schedule, eliminating massive breach of contract compensation risks.

High Client Recognition and Deepened Long-Term Cooperation Client Compliance Director comment: "HiSiaddi not only professionally resolved TMDD compliance challenges covering REACH and food-grade standards, but also followed up throughout the entire process to guarantee smooth cargo customs clearance, helping us avoid major compliance risks and economic losses. It is our most trusted Chinese compliance partner."

The client subsequently entrusted HiSiaddi with all compliance audits, certification document processing and customs clearance for raw materials sourced from China, raising annual procurement volume from 500,000 EUR to 1.5 million EUR.
This compliance crisis represents a typical pain point for overseas mid-to-high-end cosmetic enterprises sourcing TMDD: the EU imposes stringent regulations covering REACH, food-contact standards and GHS labeling for cosmetic raw materials, yet most domestic manufacturers lack awareness of EU compliance requirements and cannot supply full sets of English compliance documents, exposing clients to customs detention and production delays alongside severe compliance risks.
HiSiaddi’s core competitive advantage lies in in-depth mastery of the EU high-end chemical compliance system, familiarity with Chinese export customs clearance rules and integrated access to third-party testing resources:
1. One-stop compliance solutions covering "Compliance Diagnosis → Document Compilation → Certification Application → Packaging Rectification → Customs Clearance", rather than simple product supply;
2. Precise alignment with four core EU compliance frameworks (REACH, FCM, FDA, GHS) to eliminate information gaps and mitigate compliance risks;
3. Time and cost savings for clients, loss prevention and stable supply chain guarantees.
For overseas mid-to-high-end clients sourcing fine chemicals in China, selecting a foreign trade partner proficient in EU compliance and Chinese customs clearance regulations is critical to avoiding compliance risks, guaranteeing smooth cargo delivery and expanding European market reach. With professional compliance service capabilities, HiSiaddi has become the preferred compliance partner for overseas high-end coating, ink and beauty industry clients.
