Lead time

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

HiSiaddi safeguards the supply stability of Allantoin through the following measures:

1. Supply of one mainstream Allantoin model by 3 premium factories

(1) Performance evaluation and screening of Allantoin 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 Allantoin, 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 Allantoin

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 Allantoin 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 Allantoin 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 Allantoin sea and land shipments

Unstable logistics for Allantoin 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 Allantoin

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 Allantoin

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 Allantoin

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 Procurement Factors (Pre-transaction Risk Control)

(I) Compliance Verification for Target Market Access

Allantoin is categorized as a cosmetic active ingredient, topical pharmaceutical excipient and oral care raw material. Key regulated items include main content, related impurities, free urea, heavy metals, loss on drying, residual solvents and microorganisms.

· European Union: REACH registration, CPNP cosmetic notification, listed in the EU permitted cosmetic ingredient catalogue; pharmaceutical grades comply with EP Pharmacopoeia standards.

· North America: FDA cosmetic ingredient filing, CIR safety assessment; topical pharmaceutical raw materials meet USP specifications.

· Japan & South Korea: Dual filing for cosmetic/pharmaceutical raw materials with the Ministry of Health, Labour and Welfare; mandatory sampling tests for free urea and heavy metals.

· Southeast Asia / Middle East / South America: General daily chemical raw material standards. For transshipment to Europe, America, Japan or South Korea, single batches require full-item test reports (COA + SGS) plus raw material traceability documents. Customs will inspect MSDS and batch quality certificates; goods with excessive impurities will be detained.

(II) Selection Matching Downstream Production Processes

Appearance: White crystalline powder, slightly soluble in cold water, readily soluble in hot water and alcohols, insoluble in oils and fats.

1. Allantoin main peak content: Directly determines repair efficacy and formulation dosage; insufficient content increases feeding costs.

2. Free urea: A key synthetic by-product. Excess free urea causes skin irritation and stickiness in cream formulations; strictly controlled for infant and pharmaceutical grades.

3. Individual organic impurities: High impurity levels lead to yellowing and peculiar odors in finished products.

4. Moisture content and powder flowability: High moisture causes caking, hindering automatic feeding.

5. Temperature & light stability: Stable under neutral conditions; slight hydrolysis occurs under strong acid/alkali or prolonged high-temperature exposure. High-purity grades are preferred for transparent formulations.

6. Compatibility: Frequently compounded with panthenol, ectoin and sodium hyaluronate for repair formulas. Avoid long-term coexistence with concentrated strong acids and alkalis. Conduct cold-heat cycle stability tests in advance for new formulations.

(III) Grade Classification & Selection Standards

1. Topical Pharmaceutical Grade / Premium Infant Skincare Grade: Content ≥99.0%, free urea ≤0.1%, low heavy metal limits. Specially used for skin ointments, infant repair creams and medical dressings.

2. Standard Cosmetic Grade: Content ≥98.5%, free urea ≤0.3%. Applied to ordinary facial masks, anti-acne lotions and toothpaste raw materials.

3. Feed Grade: Content ≥98.0% with relaxed impurity limits, for livestock and pet feed supplementation.

(IV) Supplier Production Capacity & Supply Stability Assessment

Core production process: Glyoxylic acid + urea catalytic condensation → cooling crystallization → water washing purification → recrystallization → low-temperature drying. Key control points: condensation conversion rate, deep elution of free urea, impurity control via crystallization. Prioritize fine chemical synthesis and purification manufacturers with complete ISO22716 cosmetic management systems. Large factories feature minor batch fluctuations in content and free urea, and support third-party cross-border testing by SGS and Eurofins. Full-container, LCL and small trial orders are available with standard lead times of 7–10 days. Small manufacturers adopt single crude crystallization processes, which generally result in excessive free urea and disqualify products for export to European, American pharmaceutical and infant skincare markets.

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

Physicochemical properties: Slightly hygroscopic, stable at room temperature and away from light; high temperature and humidity accelerate moisture absorption and caking. Non-hazardous chemical.

· Packaging: 25kg cardboard drums lined with PE inner bags; premium pharmaceutical grades use vacuum-sealed aluminum foil inner bags.

· Storage & transportation conditions: Cool and shaded warehouse storage, storage temperature ≤30°C, relative humidity ≤65%.

· Taboos: Do not store alongside strong acids, strong alkalis or high-moisture raw materials in the same warehouse. Implement first-in, first-out inventory management to shorten stockpiling cycles.

(VI) Customized Supporting Services

Targeted purity control, ultrafine powder screening, compound repair raw materials, customized multi-language foreign labels; supporting repair formulation development, interpretation of cosmetic regulations worldwide and sorting of customs clearance documents.

II. Universal Basic Acceptance Indicators for All Grades

2. Free urea: Premium pharmaceutical grade ≤0.10%; cosmetic grade ≤0.30%.

3. Loss on drying (moisture): All grades ≤0.50%; high-purity pharmaceutical grade ≤0.30%.

4. Residue on ignition: Pharmaceutical & cosmetic grade ≤0.10%; feed grade ≤0.20%.

5. Sensory properties & solubility: Uniform white crystalline powder with no peculiar odor; fully soluble in hot water to form clear solutions. Caking and yellowing indicate moisture-induced deterioration.

6. Microorganisms: Cosmetic and pharmaceutical grades meet standards for total bacteria and mold count; pathogenic bacteria shall not be detected.

III. Special Control Indicators by Application Scenario

(I) Ointments & Infant Skincare for Europe, America, Japan & South Korea

Full compliance with heavy metal and microorganism standards; strict control of free urea to prevent stickiness, discoloration or precipitation in finished products under high/low temperature conditions.

(II) Ordinary Facial Masks & Toothpaste Raw Materials

Compliant main content and free urea levels; microorganisms meet regional daily chemical standards.

(III) Feed Additive Raw Materials

Only content, moisture and ash content require inspection.

IV. Cross-border Supporting Qualifications & Risk Control

(I) Mandatory Export Documents

Basic materials: Production qualification certificate, ISO22716 certificate, MSDS, batch-specific COA, full-item SGS test reports (content, free urea, impurities, heavy metals, microorganisms).

· EU: REACH registration + CPNP notification

· North America: FDA cosmetic filing

· Japan & South Korea: Raw material filing with Ministry of Health, Labour and Welfare Bonus certifications: HALAL, KOSHER.

(II) Inherent Product Risk Reminders

1. Slight hygroscopicity: Sealed moisture-proof packaging is required for ocean shipping to avoid insoluble caking.

2. Free urea is a critical compliance checkpoint for pharmaceutical and infant skincare export orders; full batch testing is required for high-end orders.

3. Hydrolysis and efficacy loss occur in strong acid formulations; formulate within a neutral pH range of 5.0–7.0.
