Lead time

The monthly inventory volume of Sodium hyaluronate is 10 tons, with appropriate adjustments upwards or downwards in response to peak and off-peak seasons.

HiSiaddi safeguards the supply stability of Sodium hyaluronate through the following measures:

1. Supply of one mainstream Sodium hyaluronate model by 3 premium factories

(1) Performance evaluation and screening of Sodium hyaluronate brand factories based on on-time delivery rate, batch pass rate, timeliness of risk alerts, and completeness of documentation to assess their supply stability.

(2) For each mainstream model or major grade of Sodium hyaluronate, secure 1 primary high-quality brand manufacturer and 2 backup high-quality manufacturers.

(3) Each factory operates independent production lines in separate production zones to prevent production halts caused by major unforeseen incidents such as environmental production suspensions and power outages.

2. Technological transformation partnerships and long-term sales binding for Sodium hyaluronate

Through long-term cooperation with brand manufacturers via technology commercialization and authorized distribution channels, HiSiaddi can effectively strengthen supervision over the production processes of brand manufacturers, optimize full-process traceability management, improve batch stability control, and further reinforce real-time monitoring of the supply stability of Sodium hyaluronate products.

Long-term Annual Framework Supply Guarantee Agreement. HiSiaddi signs 12-month long-term agreements with leading manufacturers. The agreements specify the minimum guaranteed supply volume, maximum price hike range, and priority production scheduling rights during peak seasons. It is stipulated that manufacturers shall issue a 30-day prior written notice if production is suspended due to environmental rectification or equipment maintenance, and backup manufacturers will be activated to replenish goods accordingly.

3. 4 warehouses and 10 peak & off-peak demand forecasting

We have 4 warehouses, which are jointly operated and managed with suppliers to store hot-selling products.The four warehouses are located at Qingdao Port in North China, Ningbo Port in East China, Shenzhen Port in South China, and Zhengzhou, China’s inland logistics hub. This setup guarantees sufficient supply and timely shipment of Sodium hyaluronate during peak seasons.

HiSiaddi issues a rolling demand forecast covering the subsequent three months on the 25th of each month, allowing manufacturers to reserve production capacity in accordance with the forecast. Any new urgent orders from overseas clients will be prioritized to draw on inventories or production capacity from backup manufacturers.

4. Multi-channel logistics to resolve vessel congestion and inspection delays for Sodium hyaluronate sea and land shipments

Unstable logistics for Sodium hyaluronate will extend delivery lead times. HiSiaddi has established alternative arrangements covering multiple freight forwarders, ports and transportation solutions:

(1) Binding of multiple professional chemical freight forwarders for Sodium hyaluronate

Each product is assigned 2 to 3 freight forwarders with hazardous chemical/food transport qualifications affiliated with different shipping lines. Alternative sailing schedules can be switched to immediately in case of space shortages or customs inspections on a single shipping route.

(2) Backup transportation solutions for Sodium hyaluronate

Ocean freight serves as the standard mode; air freight and rail freight are reserved as alternatives for urgent orders. Long-term agreements for temperature-controlled containers are signed for temperature-sensitive and perishable food additives to secure shipping space.

(3) Visual tracking and digital early warning for Sodium hyaluronate

Freight forwarders synchronize daily updates on container loading, customs declaration, vessel loading and port arrival milestones. If customs inspection occurs, replenishment from backup inventory will be initiated immediately to shorten client waiting periods.

Full-chain digital early warning automatically monitors four categories of risks:

• Factory side: Expiring supplier environmental assessment certificates, renewal of production permits, scheduled major equipment overhauls, and notifications of price hikes for upstream raw materials;

• Inventory side: Inventory falling below safety thresholds, excessive inventory age, and batches failing quality inspection;

• Logistics side: Shipping line space shortages, strikes at destination ports, and updates to customs policies;

• Overseas side: Revisions to additive regulations and adjustments to import restriction lists in target countries.

Early warning notifications are automatically pushed to procurement and business leads, allowing backup suppliers or inventory contingency plans to be activated in advance.

I. Core Comprehensive Global Sourcing Factors (Pre-Transaction Risk Control)

(I) Compliance Verification for Target Market Access

Product classifications: cosmetic raw material, food additive, pharmaceutical excipient, medical raw material. Key controlled indicators: glucuronic acid, protein content, molecular weight distribution, loss on drying, ethanol residue, endotoxin, heavy metals, microorganisms.

· EU: REACH registration, CPNP notification for cosmetic raw materials; food-grade sodium hyaluronate subject to EFSA approved catalogs; pharmaceutical excipients comply with EP Pharmacopoeia with strict control over foreign proteins and pyrogens.

· North America: FDA raw material filing; oral-grade products follow cGMP; injectable/ophthalmic-grade materials aligned with USP Pharmacopoeia.

· Japan & South Korea: Three-category filing (cosmetic/food/pharmaceutical) by Ministry of Health, Labour and Welfare; mandatory control over protein residues, microorganisms and molecular weight tolerance.

· Southeast Asia, Middle East, South America: Comply with local general standards for food and daily chemicals. For resale to EU, Japan, South Korea, batch-specific COA, full-item third-party SGS test reports and raw material traceability documents are required. Customs will inspect MSDS and batch quality inspection reports; shipments with out-of-spec indicators or incomplete qualifications will be detained and returned directly.

(II) Model Selection Adapted to Downstream Production Processes

Appearance: off-white to white powder, highly soluble in pure water, insoluble in organic solvents such as alcohol and acetone.

1. Molecular weight and distribution range: High molecular weight (above 1500 kDa) delivers strong film-forming and water-locking effects; medium molecular weight (500 kDa–1500 kDa) moisturizes skin; low molecular weight (10 kDa–500 kDa) enables transdermal absorption; ultra-low molecular weight (<10 kDa) features high oral absorbability. Deviations in molecular weight directly affect formulation viscosity, skin feel and efficacy.

2. Foreign protein residues: Critical indicator for injectable, ophthalmic and medical aesthetic grades; excessive protein easily causes sensitization and eye irritation.

3. Moisture content and powder flowability: Impact automatic filling and capsule encapsulation; high moisture leads to rapid moisture absorption and caking.

4. Acid-base and thermal stability: Stable under neutral conditions; long-term high-temperature sterilization under strong acid or alkali triggers polysaccharide degradation and sharp viscosity drop.

5. Compatibility: Frequently compounded with glutathione, alpha arbutin, ectoin and plant extracts in skincare formulas. Avoid long-term coexistence in extreme pH systems; conduct compatibility stability sample tests in advance for new formulas.

(III) Grade Classification & Selection Standards

1. Injectable/Ophthalmic Pharmaceutical Grade: Glucuronic acid ≥42.0%, protein ≤0.1%, low endotoxin, sterile, compliant with USP/EP; applied in joint injections, artificial tears and medical aesthetic filler syringes.

2. High-End Medical Aesthetic Cosmetic Grade: Glucuronic acid ≥41.5%, protein ≤0.15%, multiple molecular weight options; used for salon essences, medical cold compresses, repair lotions and toners.

3. General Daily Chemical Grade: Glucuronic acid ≥40.0%, protein within compliant limits; raw materials for affordable body wash, body lotion and regular facial masks.

4. Oral Food Grade: Comply with food additive specifications of target countries, available in low/ultra-low molecular weight specifications; for hyaluronic acid oral liquids, tablets and solid beverages.

(IV) Supplier Production Capacity & Supply Stability Assessment

Core processes: fermentation broth sterilization → crude ethanol extraction → multi-stage membrane filtration → ion exchange impurity removal → alcohol removal → spray drying/vacuum freeze-drying. Core control points: precise molecular weight regulation, foreign protein removal, organic solvent residue elimination, endotoxin removal. Prioritize manufacturers with self-owned fermentation and full-process purification lines; verify ISO22000, GMP and ISO13485 medical system certifications. Large manufacturers maintain minor batch fluctuations in molecular weight and protein indicators and support cross-border testing via SGS and Eurofins. Full-container, LCL and small trial orders are acceptable with standard lead time of 7–10 days. Small manufacturers feature primitive purification processes, elevated protein levels and unstable molecular weight, making them unable to supply medical and high-end cosmetic markets in Europe, America, Japan and South Korea.

(V) Cross-Border Packaging, Storage & Transportation Solutions
