HiSiaddi is an innovative service provider driven by both technology transformation and comprehensive services. We have established a service system defined as "1+2+3+4=1" and can supply D-biotin (Vitamin B7) sourced directly from well-known original manufacturers. Boasting independent R&D capabilities, HiSiaddi has long partnered with production plants for technological transformation. With an accurate grasp of market demands, we specialize in addressing customized requirements for D-biotin (Vitamin B7) and delivering formula optimization solutions. Below are typical cases of our customized services and formula optimization consultation for D-biotin (Vitamin B7).

Case 1: Custom Procurement of High-Purity Pharmaceutical Grade D-Biotin for a US Cosmetic Raw Material Supplier, with HiSiaddi Delivering Non-Standard Customized Products

1. Project Background & Customization Challenges

Keragen Labs, a cosmetic raw material supplier based in California, USA, mainly distributes raw materials for hair care serums and oral beauty gummies, and serves numerous high-end salon skincare brands across North America. In late 2023, the company placed an order for customized D-biotin with stricter specifications than standard FCC food-grade products:
  1. Biotin content ≥ 99.90% (compliant with EP European Pharmacopoeia pharmaceutical grade), with single organic impurity content below 0.05%;

  2. Free from exogenous corn and soybean allergens, manufactured entirely with non-GMO fermentation raw materials;

  3. 100% particle pass rate through a 100-mesh sieve, with no coarse crystals;

  4. Trial order of 150 kg for a single batch.

Most mainstream domestic biotin manufacturers mainly produce food-grade products with a purity of 98.5%~99.5%. High-purity pharmaceutical grade production requires high technical thresholds and a minimum order quantity of 500 kg. As the client only needed a small batch for new product pre-launch market testing, many manufacturers declined this customized order.

2. Full-Chain Customization Implementation by HiSiaddi

  1. Integration of upstream resources: Leveraging the supply chain resources of Zhejiang Shengda Biotech, a global core manufacturer of biotin, HiSiaddi negotiated with the plant to utilize intermittent pilot production lines for off-peak scheduling. The high-purity refining procedures were split to accept the 150 kg small-batch customized order, breaking the restrictions of large-scale mass production.

  2. Targeted adjustment of refining technology: Traditional biotin adopts high-temperature concentration and crystallization in the final process, which tends to produce trace impurities. We collaborated with the plant’s R&D team to adopt low-temperature gradient recrystallization combined with precision membrane filtration and purification technology. After four rounds of sample refining and purification, the product purity was stably maintained at 99.92%~99.95%, and single organic impurities were controlled within 0.03%, fully complying with EP Pharmacopoeia standards. A third-party SGS allergen test report issued in the United States was provided to certify the absence of corn and soybean-derived impurities.

  3. Customized sieving and packaging: A customized ultra-fine air classification process was applied to ensure 100% pass rate for 100-mesh particles. Products were packed in light-proof nitrogen-flushed aluminum foil sealed packages to prevent oxidation caused by temperature fluctuations during long-distance ocean transportation to North America. The finished goods were loaded into 20 kg food-grade paper drums lined with double-layer aluminum foil bags.

  4. North America customs clearance & compliance documents: Our compliance department compiled complete English technical documents including supporting materials for DMF filing, US FDA GRAS certification, COA and MSDS. We also applied for marine certificates of origin. Goods were shipped via Matson Clipper directly to the Port of Los Angeles, and we cooperated with a local US customs broker for pre-document review. The whole customs clearance and delivery process was completed within 3 working days after the goods arrived at the port.

3. Project Outcomes

The 150 kg customized high-purity D-biotin was delivered on schedule. The client’s new hair care serum was successfully launched in more than 120 high-end beauty salons across North America. Throughout 2024, the client placed six repeat orders with a total volume of 86 tons of pharmaceutical grade customized biotin, becoming a benchmark client of HiSiaddi in the North American cosmetic raw material sector. Relying on this cooperation, we also secured raw material procurement partnerships with 3 dietary gummy brands on the US East Coast.

Case 2: Formula Malfunction of D-Biotin for a Brazilian Livestock Premix Enterprise, Solved by HiSiaddi via Technical Optimization

1. Sudden Technical Problems in Production

Agro Nutri, a large feed group headquartered in São Paulo, Brazil, specializes in compound premixes for broilers and breeding pigs. In the first half of 2024, the company purchased domestic FCC-grade D-biotin for mass production of livestock premixes, and encountered two critical problems:
  1. During the high-temperature pelleting process (82℃), D-biotin underwent thermal decomposition. The residual rate of active biotin in finished feed was only 61%, failing to meet the Brazilian Ministry of Agriculture standard which requires a residual rate of no less than 85% for feed additives.

  2. D-biotin powder features low specific gravity and strong static electricity, leading to severe segregation when mixed with calcium carbonate and corn carriers. The content deviation of biotin in finished feed from the same batch reached ±28%, resulting in failure of factory sampling inspection. Switching to imported European and American biotin would increase procurement costs by 35%, so the client urgently turned to HiSiaddi for technical solutions.

2. Technical Diagnosis & Phased Optimization Solutions by HiSiaddi

  1. Analysis of root causes: Our technical team, together with application engineers from the raw material manufacturer, conducted remote and on-site video troubleshooting. Conventional crystal D-biotin can only withstand temperatures below 65℃, so it degraded rapidly during high-temperature pelleting. In addition, the uncoated powder generated static electricity, causing segregation when blended with heavy mineral carriers.

  2. Customized heat-resistant coated D-biotin: We coordinated with the plant to adopt a fluidized bed coating technology using hydrogenated vegetable oil and microcrystalline cellulose. The coating layer can resist short-term high temperatures up to 90℃. When applied under 85℃ pelleting conditions, the residual rate of active ingredients of the coated biotin reached over 92%. Meanwhile, the coating eliminated static electricity of the powder and completely solved the mixing segregation issue.

  3. Fine-tuning of terminal premix formula: Based on the client’s carrier ratio (65% corn flour + 22% calcium carbonate), our technicians optimized the feeding process: pre-dilute the coated biotin with 5 times its weight of corn flour first, then add the mixture into the main mixing bin. The staged feeding method eliminated content unevenness caused by specific gravity differences.

  4. Verification via multi-gradient pilot tests: We provided 3 batches of test samples with different coating thicknesses, totaling 35 kg free of charge. After 5 consecutive workshop pilot productions by the client, the measured residual rate of biotin in finished feed ranged from 89.3% to 93.1%, and the content deviation of the same batch was controlled within ±5%, fully meeting the access standards for feed in Brazil.

3. Project Outcomes

The client fully replaced raw materials with HiSiaddi’s customized heat-resistant coated D-biotin, and its annual procurement volume rose from 26 tons to 79 tons. We further promoted this technical solution for feed-specific heat-resistant coated biotin to 4 major feed groups in Argentina and Uruguay, adding annual biotin orders of over 120 tons. A standardized customized product line of biotin dedicated to livestock and poultry feed in South America was officially established.

What is HiSiaddi's inventory of D-Biotin? How is the stability of supply guaranteed?

The monthly inventory volume of VB7 is 20 tons, with appropriate adjustments upwards or downwards in response to peak and off-peak seasons.

HiSiaddi safeguards the supply stability of VB7 through the following measures:

1. Supply of one mainstream VB7 model by 3 premium factories

(1) Performance evaluation and screening of VB7 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 VB7, 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 VB7

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 VB7 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 20 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 VB7 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 VB7 sea and land shipments

Unstable logistics for VB7 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 VB7

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 VB7

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 VB7

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.
