Qingdao Lanneret Biochemical Co., Ltd. — Verified Supplier
About Qingdao Lanneret Biochemical Co., Ltd. - Sodium Alginate Supplier in China
Based in China, the company lists five active products in its catalogue. The portfolio focuses on sodium alginate variants that are used in textile applications, including a general textile grade, a high‑viscosity 1000 cps grade, a printing‑grade, and a specification‑designated SD‑45 grade. Each entry is recorded under the broader categories of Sodium Alginate and Textile Chemicals, reflecting the material’s role as a thickener, binder and sizing agent. The product list does not include additional chemicals beyond these sodium alginate forms.
The supplier’s catalogue does not provide HS‑code details, but all items fall within the chemical‑based HS chapter for organic compounds. The five products are presented without further differentiation such as purity percentages or moisture content, indicating that the supplier relies on standard industry specifications for sodium alginate. Buyers can expect the listed grades to align with typical textile‑industry requirements for viscosity and film‑forming properties.
Product Range and Specialties of Qingdao Lanneret Biochemical Co., Ltd.
The catalogue offers textile grade sodium alginate, a 1000 cps high‑viscosity grade, a printing‑grade sodium alginate, and a SD‑45 grade that is often referenced for specific fiber‑sizing performance. In the wider market, sodium alginate is supplied in grades ranging from low viscosity (around 200 cps) to high viscosity (above 2000 cps) and is graded by viscosity measured in centipoise at 25 °C. Typical specifications include purity of 95 % or higher, moisture content below 15 % and a pH of 7‑8 in solution. Buyers also look for consistent batch‑to‑batch viscosity and particle size distribution, usually expressed in micrometres.
Industry standards for textile chemicals often reference ISO 9001 quality management and, where applicable, REACH compliance for chemical safety in the European market. Sodium alginate used for printing may be required to meet colour‑fastness standards such as ISO 105‑B02, while sizing grades may be evaluated against tensile strength and break‑point tests on treated fabrics.
Trade and Export Information - Qingdao Lanneret Biochemical Co., Ltd.
China is a major exporter of sodium alginate, supplying textile manufacturers in South‑East Asia, South Asia and Europe. The typical HS‑code for sodium alginate falls under 3901.10 (natural gums) and 3914 (polymers of sugars), which are subject to customs documentation that includes a Certificate of Origin and safety data sheets. Importing regions often request REACH registration for EU shipments and comply with the US EPA TSCA inventory for North American imports.
Logistics for these bulk chemicals usually involve 20‑ft or 40‑ft containers, with the product packed in food‑grade polyethylene drums or bulk bags that meet UN 2070 specifications for hygroscopic powders. Common Incoterms are FOB Qingdao or CIF major ports such as Shanghai, allowing buyers to arrange inland transport. Exporters from China typically provide a Material Safety Data Sheet (MSDS), test reports for viscosity and purity, and may need to secure an export licence if the product is classified as a controlled chemical in the destination country.
Sourcing from Qingdao Lanneret Biochemical Co., Ltd. - Buyer Guidance
When sourcing sodium alginate from this supplier, request the latest MSDS, a viscosity test report at 25 °C, and a purity analysis showing the percentage of alginate versus residual salts. Verify whether the product complies with REACH or TSCA requirements for your target market, and ask for a sample batch to confirm film‑forming performance on your specific textile substrate.
Check the packaging details to ensure the drums or bulk bags meet your storage conditions, and confirm the lead time for production, which for specialty grades such as SD‑45 can range from two to four weeks. Clarify the Incoterm and who will handle customs clearance, and obtain a non‑binding quotation that includes freight terms before placing a purchase order.
Frequently Asked Questions About Qingdao Lanneret Biochemical Co., Ltd.
What types of sodium alginate does Qingdao Lanneret Biochemical offer?
The supplier lists five variants: a general textile grade, a 1000 cps high‑viscosity grade, a printing‑grade, an SD‑45 grade and a standard sodium alginate product.
Which HS codes apply to the listed sodium alginate products?
They fall under HS chapter 39, commonly HS 3901.10 for natural gums or HS 3914 for polymeric sugar derivatives, depending on the exact formulation.
What quality specifications should a buyer verify for textile sodium alginate?
Typical checks include viscosity (cPs at 25 °C), purity (≥95 %), moisture content (<15 %), and pH (7‑8). Additional tests may cover film‑forming strength on cotton or polyester fabrics.
Are any certifications required for importing these chemicals into the EU?
Importers usually need REACH registration and a Certificate of Origin, and may request ISO 9001 compliance documentation from the supplier.
What packaging formats are commonly used for bulk sodium alginate shipments?
Bulk shipments are typically packed in food‑grade polyethylene drums (≈200 kg) or 25‑kg bulk bags that meet UN 2070 standards for hygroscopic powders.
What are typical lead times and minimum order quantities for the SD‑45 grade?
Lead times are generally two to four weeks after order confirmation, and minimum orders are often set at one 20‑ft container (approximately 10‑12 tons) unless otherwise negotiated.
How can a buyer request a sample before a full order?
Buyers should contact the supplier with a written sample request, specifying the grade, intended textile application, and desired test parameters; the supplier will arrange shipment of a small drum or bag under the agreed Incoterm.
What documentation accompanies the shipment for customs clearance?
Customs typically require a commercial invoice, packing list, Certificate of Origin, Material Safety Data Sheet, and any applicable test certificates for viscosity and purity.
