Purchaser: NATURFEM, a leading mid-to-high-end biotech enterprise based in Germany. Its products are sold at premium health pharmacies DM and Rossmann across Germany plus private gynecological clinics, focusing on PCOS fertility compound capsules and solid powder drinks. All products comply with EU EFSA, USP, Clean Label and German LFGB access standards, with an annual DCI procurement demand of 28 tons. Previously sourcing from European manufacturers, the brand planned to switch to domestic Chinese suppliers to compress supply chain costs.
Core Client Difficulties:
1. The client independently contacted 5 mainstream domestic DCI raw material manufacturers (Guanjie Biotech, Haotian Pharmaceutical, Xinbeilai Biomedicine, Xi’an Jintai Biotech, Huaheng Biotech). Each manufacturer only promotes its own products, highlighting exclusive advantages while concealing peer drawbacks and its own process limitations, without objective horizontal comparison.
2. The client cannot distinguish three production routes: biological fermentation, D-pinitol hydrolysis and plant extraction. Mixed specifications of 98%, 99% and 99.6% purity grades exist on the market with inconsistent particle size, residual solvent, chiral purity and powder flowability parameters. Incorrect raw material selection directly causes filling blockages on German production lines, substandard finished product shelf life and failed EU filings.
3. Manufacturers differ widely in quotations, minimum order thresholds, quality control standards and compliance certificates. Lacking domestic raw material industry insights, the client could not accurately match raw material requirements for its dual capsule and powder production lines and delayed procurement finalization. The brand entrusted HiSiaddi to conduct neutral full-brand evaluation and grade screening.
Drawing on raw material databases and third-party laboratory sample testing, HiSiaddi conducted objective horizontal evaluation of full product lines from 5 top manufacturers without manufacturer-biased thinking, sorting out production processes, grades, advantages, disadvantages and applicable scenarios for each brand:
· Main Grades: DCI-98 (Carob Extract Grade), DCI-99HP (High-Purity Food Grade)
· Advantages: Natural carob extraction route with prominent Clean Label advantages; overseas warehouse in New Jersey, USA; complete Halal, Kosher and FDA certifications; flexible small minimum order quantity (1kg sampling); excellent water solubility of powder.
· Disadvantages: High production cost for 99HP grade with obvious price surcharges for bulk orders; limited capacity for fine high-mesh screening with excess fine powder, unsuitable for high-speed hard capsule filling lines.
· Applicable Scenarios: Powder drinks and single-serve solid beverage formulas.
· Main Grades: DCI-BIO99 (Enzymatic Bioconversion Grade), DCI-CH98 (Standard Pinitol Hydrolysis Grade)
· Advantages: Self-developed whole-cell bioconversion production lines independent of D-pinitol chemical raw materials, ultra-low residual solvents, stable chiral purity ≥99.5%; customizable regular particles of 80–120 mesh with excellent powder flowability; 10,000-ton annual production capacity with controllable costs for bulk procurement.
· Disadvantages: Standard CH98 hydrolysis grade contains excessive impurities and inorganic salts, only suitable for low-end food additives and prohibited for high-end formulations; high minimum order threshold for biological grade with optimal single purchase ≥3 tons.
· Applicable Scenarios: Mid-to-high-end capsules and core raw materials for clinic-grade nutraceuticals.
· Main Grades: DCI-PH99.6 (Pharmaceutical Refined Grade), DCI-F99 (Standard Food Grade)
· Advantages: Refined production processes aligned with USP pharmacopoeia, HPLC purity ≥99.6%, heavy metals <0.1ppm, strictly controlled isomer impurities ≤0.15%; complete English process traceability documentation required for German drug regulatory authorities.
· Disadvantages: Full product line pricing is premium with limited mass production capacity and extended delivery times during peak seasons, unsuitable for large-volume mass low-cost production.
· Applicable Scenarios: Pharmaceutical-grade capsules and customized high-value clinic products.
· Main Grade: DCI-XT98 (Standard Plant Hydrolysis Grade)
· Advantages: Lowest mass production cost with sufficient off-the-shelf inventory, high cost performance for standard food applications.
· Disadvantages: Full product line adopts D-pinitol acid hydrolysis with excessive solvent residues and inorganic impurities, lacking Clean Label certification and failing EU Clean Label audits.
· Main Grade: DCI-FER99 (Glucose Full Fermentation Grade)
· Advantages: Leveraging listed company fermentation technology with clear raw material traceability, fully enclosed full-chain production free of GMO and chemical additives; obvious price advantages for large-scale centralized procurement.
· Disadvantages: Standard off-the-shelf products have rough particle sizes; customized particle sizes require additional production scheduling with delivery lead times of 15–20 days.
· Applicable Scenarios: Long-term annual framework bulk procurement and compound myo-inositol blended raw materials.
The client’s production lines include high-speed hard capsule lines (70% procurement share) and instant powder lines (30% procurement share). Balancing EU labeling regulations, filling physical properties and annual 28-ton batch stocking requirements, HiSiaddi eliminated Jintai Biotech’s low-end hydrolysis raw materials and finalized two mid-to-high-end manufacturers (Haotian Pharmaceutical and Guanjie Biotech) with three dedicated grades precisely matched to separate production lines:
1. Grade ① DCI-BIO99 (Standard Bioconversion Grade): For the client’s flagship PCOS hard capsules, chiral purity of 99.52%, particle size 90–110 mesh, repose angle 34°, free of bridging and blockages during high-speed capsule filling, compliant with German LFGB and USP standards. Annual core procurement volume of 20 tons delivered in monthly batches.
2. Grade ② DCI-BIO-CUS (Fine-Tuned Custom Grade): For small-batch trial production of the client’s new high-content compound capsules, crystallization parameters adjustable on demand with locked purity of 99.6%, fixed annual demand of 3–4 tons for new product materials.
1. Grade ③ DCI-99HP (High-Purity Carob Extract Grade): Exclusively for client single-serve instant stick pack powder. Natural carob source fully complies with Clean Label requirements, allowing plant-derived labeling on EU raw material tags with excellent water solubility and precipitate-free reconstitution. Fixed annual procurement volume of 5 tons.
Xinbeilai PH99.6 pharmaceutical grade meets quality standards but carries a 27% price premium over selected raw materials, unaffordable for the client’s mass production costs. Huaheng fermentation grade offers outstanding cost performance but long customized particle size lead times incompatible with the client’s existing inventory turnover plan, reserved as an alternative supplier for future new products.
1. Sample Phase: HiSiaddi coordinated air shipment of 50g samples of all three grades to the client’s German laboratory for capsule filling, powder reconstitution and 90-day accelerated stability testing, with all three grades fully complying with German quality inspection standards.
2. Initial Trial Order: Total procurement of 1.8 tons (1.3 tons Haotian BIO99 + 0.5 tons Guanjie 99HP), shipped from Shanghai Port to Hamburg. HiSiaddi assisted in compiling full English compliance documents including LFGB, SDS and COA with zero customs clearance abnormalities.
3. Signing of Annual Long-Term Framework Contract: After successful trial production, a full-year 28-ton framework procurement contract was signed. Haotian reserved exclusive bioconversion production lines and Guanjie fixed dedicated extraction sections, with unchanged grade parameters and locked pricing for 6 months.
4. Value-Added Services: HiSiaddi maintained dual-brand raw material files, synchronized updates to EU EFSA regulations, and coordinated free manufacturer grade parameter adjustments for annual new product R&D.
1. Industry Pain Points: Domestic raw material manufacturers adopt self-promotion business models and withhold objective peer advantages and internal production drawbacks for commercial interests. Overseas mid-to-high-end brands lack factory inspection and raw material physical property identification capabilities, risking overpriced mismatched raw materials or improper use of low-end hydrolysis materials in high-end formulations.
2. Mid-to-High-End Overseas Procurement Requirements: Nutraceuticals sold at EU pharmacies are restricted by both labeling regulations and formulation equipment. Raw material production routes, crystal particle size and impurity indicators are directly tied to product filings; single-manufacturer sales pitches easily lead to incorrect sourcing decisions.
3. HiSiaddi Core Value: Acting as a neutral third-party foreign trade service provider independent of single manufacturer sales interests, we conduct horizontal cross-brand pros & cons analysis and reverse-source raw materials based on clients’ end-formulation production processes, balancing quality, cost and compliance as a critical link for overseas mid-to-high-end brands switching to domestic Chinese raw material sourcing.
