FAQ

Yes, we are a professional manufacturer of pharmaceutical excipients established in January 2010, officially named Shandong Liaocheng Huayang Pharmaceutical Excipients Co., Ltd. We have our own Huayang Pharmaceutical Industrial Park covering an area of 20,000㎡, with fully automated production lines and inspection equipment designed and built in accordance with GMP standards. We are not a trading company, so we can directly control product quality and delivery schedules to provide stable supply for our customers.

We have obtained a series of authoritative certifications and honors to meet global regulatory requirements, including:

• National qualification certification from the National Medical Products Administration of China
• Recognition as a "High-Tech Enterprise" in Shandong Province and a provincial-level "Specialized, Refined, Peculiar, and Innovative" SME
• Membership in IPEC China (International Pharmaceutical Excipients Council China)
• Certifications for ISO9001 Quality Management System and ISO14001 Environmental Management System

All our products comply with the standards of the Chinese Pharmacopoeia (ChP 2020/2025 editions), and relevant certification documents can be provided upon your request.

Our fully automated production lines enable stable annual production capacity for core products: the annual output of corn starch (pharmaceutical grade) exceeds 3,000 tons, and the annual output of dextrin (pharmaceutical grade) exceeds 2,500 tons. Over the years, we have served well-known domestic pharmaceutical groups such as Jianmin Pharmaceutical Group, CSPC Group, and Jichuan Pharmaceutical Group. We have sufficient production capacity to meet large-volume orders from overseas markets, and the delivery cycle can be flexibly adjusted according to the order quantity.

Our core products mainly cover two categories, with clear application scenarios in the pharmaceutical field:

• Corn Starch (CAS No.: 9005-25-8): As a filling agent, binder, diluent, and disintegrant, it is widely used in tablet production (to help tablets form and disintegrate in the body, promoting drug absorption) and capsule filling. It can also be used in granules that are not sensitive to moisture.
• Dextrin (CAS No.: 9004-53-9): As a binder, filling agent, disintegrant, and 成型 agent, it is mainly used in tablet and pill production (enhancing the cohesion of drug powders to improve tablet hardness) and granular formulations (especially for products with clarity requirements).

he four models of corn starch are differentiated by core properties such as moisture content, particle size, and microbial limits, and are suitable for different pharmaceutical scenarios:

FBD-A (Ordinary) | Basic adaptability, moisture loss 7.0%-8.0% | General tablets (as excipient/diluent) and capsule filling; used with powdered sugar/dextrin to increase tablet hardness 

|FBD-B (Low-moisture) | Good fluidity, moisture loss 4.0%-7.0% | Production of moisture-sensitive APIs (tablets, granules, capsules); used as disintegrant in tablets 

|FBD-C (Ultra-fine) | Excellent fluidity, 200 mesh (finer particles) | Preparations requiring high fineness (film-coated tablets, pellets); improves preparation uniformity 

|FBD-D (Low-bacteria) | Strict microbial limits (aerobic bacteria <100 cfu/g) | Sterile preparations and oral suspensions (e.g., cephalosporins, penicillins) with high microbial control requirements |

You can choose the model based on the sensitivity of APIs to moisture, the fineness requirements of preparations, and microbial control standards. Our technical team can also provide customized recommendations.

Currently, our products are mainly produced in accordance with the Chinese Pharmacopoeia (ChP 2020/2025 editions) (the specific standards are detailed in the product quality standard table). If customers require compliance with USP (United States Pharmacopoeia), EP (European Pharmacopoeia), or BP (British Pharmacopoeia) standards, we can adjust the production process and quality inspection indicators according to the specific versions of the pharmacopoeia required by customers. The adjustment cycle is usually 4-6 weeks, and a pre-production sample test can be provided to confirm compliance before mass production.

• Standard MOQ: For corn starch and dextrin, the standard MOQ is1000kg (40 bags, as each bag is 25 kg in standard packaging).
• Sample Order: We support sample orders, with a minimum sample quantity of 25 kg per product/model. The sample fee is 1.5 times the bulk price, and the sample fee can be deducted from the subsequent bulk order payment.
• Bulk Order Discount: For orders exceeding 10,000 kg, we can provide a 3%-5% discount based on the order quantity and product type.

• Standard Packaging: Both corn starch and dextrin use woven bags lined with pharmaceutical-grade polyethylene film bags, with a net weight of 25 kg per bag. The outer packaging is marked with product name, model, batch number, shelf life, and storage conditions in both Chinese and English.
• Customized Packaging: We can provide customized packaging according to customer requirements, including:
  • Small packaging: 1 kg/bag or 5 kg/bag (aluminum-plastic composite film, suitable for small-batch use or retail)
  • Large packaging: 500 kg/bag (flexible freight bags, suitable for bulk transportation)
  • Private labeling: Printing the customer's brand logo and specified information on the packaging (minimum order quantity for private labeling is 500 kg)

The cost of customized packaging will be calculated separately based on the packaging material and specification requirements, and the production cycle will be extended by 3-5 days.

• In-stock Products: For standard models (e.g., FBD-A corn starch, FBH-A dextrin) with inventory, the goods can be shipped within 3-5 working days after the payment is received.
• Customized Products: For products that need to be produced according to customized standards (e.g., complying with USP/EP standards, customized moisture content), the production cycle is 2-3 weeks, and the delivery cycle is 1-2 weeks after production is completed (depending on the destination port).
• Urgent Orders: For urgent orders (e.g., order quantity ≤ 500 kg), we can arrange priority production, and the delivery cycle can be shortened to 7-10 working days (a 10% urgent fee will be charged).

We implement a three-tier quality control system throughout the production process to ensure product quality meets standards:

• Raw Material Inspection: We only purchase corn from designated suppliers that meet food-grade standards. Each batch of raw corn is tested for moisture content, impurity content, and mycotoxin (e.g., aflatoxin) content. Only qualified raw materials can enter the production line.
• In-process Monitoring: During the production process (e.g., starch extraction, dextrin heating modification), we conduct real-time monitoring of key indicators:
  • For corn starch: Monitor particle size distribution (using a laser particle size analyzer) and moisture content (every 2 hours).
  • For dextrin: Monitor viscosity (using a rotational viscometer) and reducing sugar content (every 1.5 hours).
• Final Product Batch Testing: Each batch of finished products undergoes a full-item inspection in accordance with the Chinese Pharmacopoeia (ChP 2020/2025 editions) or agreed international standards, including appearance, acidity, heavy metal content (e.g., lead, mercury), microbial limits (aerobic bacteria, mold, Escherichia coli), and disintegration performance. Only products that pass all inspections are allowed to leave the factory.

We attach great importance to product quality complaints and have established a complete after-sales quality guarantee mechanism:

• Complaint Response: After receiving a quality complaint from a customer, we will respond within 24 hours and assign a dedicated technical engineer to communicate with the customer to understand the specific quality issues (e.g., unqualified indicators, abnormal appearance) and collect relevant evidence (e.g., photos of the product, test reports).
• Inspection and Confirmation: We will arrange a re-inspection of the corresponding batch of products in our laboratory. If necessary, we can also entrust a third-party authoritative testing institution (e.g., SGS, Intertek) to conduct a neutral test.
• Compensation and Handling:
  • If the quality issue is confirmed to be caused by our production, we will provide free replacement of the defective products within 15 working days, and bear the round-trip transportation costs.
  • If the quality issue causes losses to the customer's production, we will compensate according to the actual loss (based on the customer's loss certificate and the agreement signed by both parties).
• Preventive Measures: After handling the complaint, we will conduct a root cause analysis of the quality issue, optimize the production process or quality control standards, and provide a preventive measure report to the customer to avoid similar issues from recurring.

We support various international shipping terms to meet the different needs of customers, and the shipping time varies by destination:
