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

Hangzhou Bais Chemical Technology Co., Ltd is based in Hangzhou, China and currently lists 47 distinct chemical products. The catalogue covers a spectrum of industrial chemicals, including organic acids, corrosion inhibitors, and specialty phosphorous compounds, each identified by CAS numbers such as 72162-23-3 for Dibasic Acids and 141-22-0 for Ricinoleic Acid. Where provided, the HS‑code families fall under Chapter 38 (e.g., 3823.12 for Ricinoleic Acid Condensate) and Chapter 29 (e.g., 2918.90 for Sodium 2‑ethylhexanoate).

The supplier’s top categories span Chemicals & Allied Products, Industrial Chemicals, Salt, Touch Screen/LCD Monitors, Automobile Spare Parts, Aluminum Ingots, Chemical Salts and Agriculture. Within the chemical segment, products include metal corrosion inhibitors (e.g., Aluminium Corrosion Inhibitor - HS 3811.21), zinc pyrithione, various sulfonamide‑derived acids, and dithiophosphate derivatives. The list also contains several specialty acids such as Glycolic Acid (CAS 79-14-1) and Dodecanedioic Acid (CAS 693-23-2), reflecting a focus on both intermediate and performance‑grade chemicals.

Product Range and Specialties of Hangzhou Bais Chemical Technology Co., Ltd

The catalogue features a mix of organic acids (Dibasic Acids, Glycolic Acid, Undecanedioic Acid), phosphorous‑based agents (Triphenyl Phosphorothionate, Molybdenum Dithiophosphate), and metal‑focused corrosion inhibitors (Aluminium Corrosion Inhibitor, Zinc Pyrithione). In the industry, such acids are typically supplied in technical grade (>95 % purity) or reagent grade (>99 % purity) and are often packaged in 200 kg IBC drums or 20 ft containers for bulk shipments. Ricinoleic Acid Condensate (HS 3823.12) is commonly used as a castor‑oil derivative in lubricants and is graded by iodine value and free fatty acid content. Sodium 2‑ethylhexanoate (HS 2918.90) is a standard metal‑working fluid additive, usually specified to meet ISO 18287 for purity and moisture.

Trade and Export Information - Hangzhou Bais Chemical Technology Co., Ltd

China is a major exporter of specialty chemicals, and products classified under HS 38 and 29 are regularly shipped to Southeast Asian manufacturers, European chemical distributors, and North American OEMs. Buyers of corrosion inhibitors and organic acids typically require compliance with REACH, GHS, and ISO 9001 quality management systems, and they expect a full Safety Data Sheet (SDS) and Certificate of Analysis (COA) with each shipment. Standard export logistics involve FOB Hangzhou port or CIF to major hubs such as Rotterdam, Los Angeles, or Singapore, with container loading in 20 ft or 40 ft units depending on volume. The Chinese chemical export sector emphasizes proper labeling, HS‑code accuracy, and pre‑shipment inspection by agencies such as CIQ or SGS.

Sourcing from Hangzhou Bais Chemical Technology Co., Ltd - Buyer Guidance

When sourcing from Hangzhou Bais Chemical Technology, request the latest SDS, COA, and any REACH registration documents for the specific CAS‑listed product. Verify the HS code matches the material description (e.g., 3823.12 for Ricinoleic Acid Condensate) and confirm purity specifications meet your application’s tolerance, typically 95‑99 % for technical use. It is prudent to ask for a sample batch of at least 5 kg to run independent analytical tests before committing to bulk orders, and to clarify the MOQ, which commonly starts at 1 metric ton for bulk chemicals, with a typical lead time of 30‑45 days after order confirmation.

What chemical product categories does Hangzhou Bais Chemical Technology list?

The supplier lists organic acids, metal corrosion inhibitors, phosphorous‑based additives, sulfonamide‑derived acids, and various dithiophosphate derivatives, all identified by their CAS numbers.

How can I request a sample of a listed chemical?

Contact the supplier through the trade platform to specify the product name, CAS number and desired sample weight (usually 5 kg). The supplier will arrange shipment of the sample in a sealed container with accompanying SDS.

Which certifications should I ask for before purchasing?

Ask for a current Certificate of Analysis, Safety Data Sheet, and any REACH registration or ISO 9001 quality system certificates that apply to the specific chemical.

What HS codes apply to the chemicals in the catalogue?

Ricinoleic Acid Condensate uses HS 3823.12, Aluminium Corrosion Inhibitor uses HS 3811.21, and Sodium 2‑ethylhexanoate uses HS 2918.90; other products fall under the broader Chapter 38 chemical codes.

What are the typical packaging options for these chemicals?

Bulk chemicals are commonly packed in 200 kg IBC drums, 25 kg fiber drums, or bulk 20 ft/40 ft containers, with inner liners to prevent moisture ingress.

What is the usual minimum order quantity and lead time?

Minimum order quantities are generally 1 metric ton for bulk chemicals, and lead times range from 30 to 45 days after order confirmation, depending on product availability.

Are the chemicals compliant with European REACH regulations?

Compliance depends on the individual product; the supplier should provide REACH registration documentation for each chemical upon request to confirm suitability for the EU market.
