About Shandong Taihe Water Treatment Co. Ltd - Water Treatment Chemicals Supplier in China

Based in China, Shandong Taihe Water Treatment Co. Ltd currently lists six distinct water‑treatment chemical products in its catalogue. The product set includes a maleic‑acid/ acrylic‑acid copolymer, a proprietary PCA additive, a carboxylate‑sulfonate‑non‑ionic tri‑polymer (Th‑3100), two entries for polyacrylic acid (PAA) and a hydrolyzed polymaleic anhydride (HPMA). All items fall under the HS chapter 38 family for organic chemical products, which is the standard classification for polymeric water‑treatment agents. The catalogue does not provide individual HS codes, but the group is typically reported under HS 3824.90 for other chemical products.

These chemicals are used as dispersants, scale inhibitors, or flocculants in industrial water‑treatment systems. The copolymer of maleic and acrylic acid and the HPMA variant are commonly employed to control hardness and prevent precipitation, while polyacrylic acid serves as a high‑molecular‑weight polymer for sludge reduction. The Th‑3100 tri‑polymer combines carboxylate and sulfonate groups to enhance compatibility with a wide pH range. The catalogue lists the products by name only, without detailed grade or performance specifications.

Product Range and Specialties of Shandong Taihe Water Treatment Co. Ltd

The listed products belong to the polymeric water‑treatment sector, where typical specifications include a molecular weight range of 1,000 - 5,000 kDa for polyacrylic acid, an acid number between 30 - 70 mg KOH per gram for maleic‑acid copolymers, and purity levels above 98 % by weight. In practice, buyers look for defined viscosity (10 - 30 cP at 25 °C) and consistent pH stability from 3 to 10. The Th‑3100 tri‑polymer is often supplied as a solid or aqueous dispersion with a solids content of 30 - 40 % w/w, while hydrolyzed polymaleic anhydride is typically presented as a powder with particle size below 200 µm. Standard industry grades are classified as industrial‑grade for bulk treatment or premium‑grade for high‑purity applications such as semiconductor water reuse.

Material safety data sheets (SDS) normally detail hazardous classifications under GHS, and test certificates may include FTIR spectra, molecular‑weight distribution (GPC), and residual monomer content. These documents help buyers verify that the chemicals meet the technical requirements of their specific water‑treatment processes.

Trade and Export Information - Shandong Taihe Water Treatment Co. Ltd

China is a major exporter of polymeric water‑treatment chemicals, with shipments regularly directed to Southeast Asia, the Middle East, Europe and North America. The HS 3824.90 code covers most of the listed polymers, and customs authorities in importing countries often require a commercial invoice, packing list, and a certificate of origin. Common buyer‑required certifications include ISO 9001 quality management, REACH registration for the EU, and EPA TSCA compliance for the United States. Packaging is typically in 25 kg polypropylene drums or 1 ton bulk containers, and freight is arranged in 20 ft or 40 ft containers depending on volume.

Incoterms such as FOB or CIF are frequently used for these bulk chemicals, with temperature‑controlled storage recommended for polymers sensitive to moisture. Export documentation may also request a third‑party analysis report confirming molecular weight and acid number, especially for high‑value industrial applications.

Sourcing from Shandong Taihe Water Treatment Co. Ltd - Buyer Guidance

When sourcing from Shandong Taihe, buyers should request a current SDS, a recent batch analysis report, and, if applicable, REACH registration evidence for the specific polymer. Verifying the acid number, molecular‑weight distribution and moisture content against the intended process parameters helps reduce the risk of incompatibility. Samples are usually supplied in 1 kg sealed bags, and a trial order of a 5 ton container can confirm performance before scaling up.

It is advisable to confirm the packaging material (e.g., HDPE drum with inner liner) and the agreed Incoterm before shipment. Buyers should also ensure that the supplier can provide a certificate of analysis (CoA) that lists purity, pH stability range, and any residual monomers, as these data are standard checkpoints in water‑treatment chemical procurement.

What types of water‑treatment chemicals does Shandong Taihe list?

The catalogue includes six polymeric products: a maleic‑acid/acrylic‑acid copolymer, a PCA additive, the Th‑3100 carboxylate‑sulfonate‑non‑ionic tri‑polymer, two entries for polyacrylic acid (PAA) and a hydrolyzed polymaleic anhydride (HPMA). Each product is intended for use as a dispersant, scale inhibitor or flocculant in industrial water‑treatment systems.

Which HS code family do these products fall under?

These chemicals are generally classified under HS chapter 38 for organic chemicals, most commonly under HS 3824.90 which covers "Other organic chemical products". Importers typically use this code for customs declarations of polymeric water‑treatment agents.

What specifications should a buyer verify for the polyacrylic acid products?

Buyers usually check molecular weight (1,000 - 5,000 kDa), purity (>98 % by weight), viscosity (10 - 30 cP at 25 °C) and moisture content (below 0.5 %). A certificate of analysis should also list any residual monomers and pH stability range.

Are any certifications required when importing these polymers?

Importing countries often require proof of ISO 9001 quality management, REACH registration for EU shipments, and EPA TSCA compliance for the United States. Buyers should request copies of these certificates or confirmation that the supplier’s products are registered where applicable.

What is the usual packaging and container size for bulk shipments?

Bulk shipments are commonly packed in 25 kg polypropylene drums or sealed 1‑ton bulk containers. Depending on order volume, the drums are loaded into 20 ft or 40 ft ocean containers for sea freight.

How can a buyer obtain a sample before placing a larger order?

Shandong Taihe can provide a 1 kg sealed sample bag upon request. The sample is accompanied by a certificate of analysis and an SDS, allowing the buyer to evaluate performance against process requirements.

What documentation is typically needed for customs clearance of these chemicals?

Standard documents include a commercial invoice, packing list, certificate of origin, material safety data sheet (SDS) and a third‑party analysis report confirming key parameters such as acid number and molecular weight. Providing these documents in advance helps avoid delays at the port of entry.
