About Hangzhou Bayee Chemical Co., Ltd. - Chemicals & Allied Products Supplier in China

Based in Hangzhou, China, Hangzhou Bayee Chemical Co., Ltd. lists 28 active products across chemicals and allied products. The catalogue includes phosphorous acid variants, organosilicon intermediates such as trimethylchlorosilane and methyltrichlorosilane, industrial fluids like MH‑Fluid (HS 3403.19), and agricultural chemicals including imidacloprid 95 % TC (HS 3808.91). Inorganic salts are represented by sodium acetate (HS 2915.23) and potassium acetate (HS 2915.29), while potassium peroxymonosulfate appears under HS 2833.40. Silica products are offered as precipitated silica (Fumde Silica, HS 2811.22). Each entry is linked to a specific HS‑code family and material description, providing clear customs classification for buyers.

The supplier’s top categories are listed as Chemicals & Allied Products, Industrial Chemicals, Agricultural Chemicals and Silica Sand, reflecting a focus on bulk‑grade intermediates and specialty agro‑chemicals. Products such as tri‑isobutyl phosphate (HS 2919.90) and tetrakis‑phosphonium sulfate (HS 2931.90) illustrate the technical breadth of the portfolio, while silicone fluids (e.g., D4, D5, PDMS) round out the offering for polymer and coating applications.

Product Range and Specialties of Hangzhou Bayee Chemical Co., Ltd.

Hangzhou Bayee’s catalogue covers a spectrum of inorganic salts, organophosphate esters, organosilicon reagents and silica sand. Sodium acetate and potassium acetate are supplied in anhydrous or hydrated forms, typically meeting purity levels of 99 % or higher, which aligns with the common specification for food‑grade and chemical‑grade applications. Organosilicon compounds such as trimethylchlorosilane, methyltrichlorosilane and dimethyldichlorosilane are usually required at ≥99.5 % purity for silicone polymer synthesis, and buyers often request a Certificate of Analysis confirming water and chlorine‑containing impurity limits. Agricultural chemicals like imidacloprid 95 % TC are standard technical concentrates used in seed‑treatment and foliar sprays, where the active ingredient content and moisture are the primary quality parameters. Silica sand (precipitated silica, HS 2811.22) is typically specified by particle size distribution (e.g., D50 10‑30 µm) and bulk density for use in fillers and polishing compounds.

Trade and Export Information - Hangzhou Bayee Chemical Co., Ltd.

China remains a major exporter of industrial chemicals, with the EU, United States and Southeast Asian markets importing the majority of organosilicon reagents and agro‑chemical intermediates. HS‑code families represented in this catalogue - 2915 (organic chemicals), 2833 (peroxy‑sulphates), 2919 (organic compounds), 3808 (pesticides), 2931 (organosilicon compounds) and 2811 (silica) - are routinely inspected under customs regimes that require a full Material Safety Data Sheet (MSDS) and a Certificate of Analysis for each shipment. Importers typically request REACH registration documentation for EU destinations and EPA registration for U.S. pesticide‑related products. Standard logistics involve bulk shipments in 20‑ft or 40‑ft containers, often using 200 L steel drums for liquids or IBC totes for powders, with Incoterms such as FOB Hangzhou or CIF major ports like Shanghai.

Sourcing from Hangzhou Bayee Chemical Co., Ltd. - Buyer Guidance

When sourcing from Hangzhou Bayee, buyers should request the latest MSDS, COA and, where applicable, REACH or EPA registration certificates before placing an order. Verify that the declared purity (e.g., ≥99.5 % for organosilicon reagents) matches the test report and that moisture content for salts is within the specified range (typically <0.5 % for anhydrous grades). Confirm packaging details - drum size, inner‑liner material, and whether the product is shipped under nitrogen blanketing - to ensure stability during transit. It is prudent to obtain a sample batch for independent testing, especially for high‑value intermediates such as imidacloprid TC or tetra‑phosphonium sulfate, to validate assay and impurity limits before full‑scale procurement.

What HS codes are associated with the chemicals offered by Hangzhou Bayee?

The catalogue includes HS 2915.23 for sodium acetate, 2915.29 for potassium acetate, 2833.40 for potassium peroxymonosulfate, 2919.90 for tri‑isobutyl phosphate, 3808.91 for imidacloprid 95 % TC, 2931.90 for several organosilicon compounds, 3403.19 for the multi‑component industrial fluid (MH‑Fluid) and 2811.22 for precipitated silica.

Which certifications should a buyer request for the organosilicon products?

Buyers normally request a Certificate of Analysis confirming ≥99.5 % purity, an MSDS, and evidence of ISO 9001 quality management or REACH registration when shipping to the EU. Additional testing reports for chlorine‑containing impurities are common.

What are typical packaging formats for the salts and silicates?

Sodium and potassium acetates are usually packed in 200 L steel drums or 25 kg fiber drums, while precipitated silica (Fumde Silica) is shipped in bulk bags (25 kg) or IBC totes, all sealed to prevent moisture ingress.

What documentation is required for the pesticide imidacloprid 95 % TC?

Importers should obtain a full MSDS, a Certificate of Analysis showing the 95 % active ingredient content, and the relevant pesticide registration certificates (e.g., REACH for EU, EPA for the United States).

Are there minimum order quantities (MOQs) for the listed products?

MOQs vary by product; bulk chemicals such as sodium acetate typically start at 1 tonne, while specialty organosilicon reagents may have an MOQ of 500 kg. Specific quantities are confirmed during the quotation process.

What lead times are typical for shipments from Hangzhou Bayee?

Standard lead times range from 15 to 30 days after order confirmation, depending on product availability, required documentation and the chosen Incoterm (FOB Hangzhou or CIF Shanghai).

How are the silicone fluids like D4 and D5 classified for export?

These silicone fluids fall under HS 2905‑90 (organic compounds) and are subject to environmental regulations; buyers often request a REACH safety data sheet and proof of compliance with VOC limits.

What quality tests are commonly performed on the silica sand product?

Quality checks include particle size distribution (D10, D50, D90), bulk density, moisture content (<0.2 %) and purity (≥99.9 % SiO₂), with results provided in an accompanying test report.
