About NanTong HaoTai Products & Chemicals Co., Ltd. - Chemicals & Allied Products Supplier in China

China based NanTong HaoTai Products & Chemicals Co., Ltd. lists nine active chemical products across the Chemicals & Allied Products and Agriculture categories. The catalogue includes organotin compounds such as Monobutyltin Oxide, Stannous Octoate and Butyltin tris(2‑ethylhexanoate), organic zinc catalysts, and several organotin catalysts with HS codes 2931.90, 2931.69 and 3824.99. The listed HS‑code families place most items in Chapter 29 (organic chemicals) and one in Chapter 38 (other chemical products). Each entry provides the chemical formula or composition, for example Dibutyltin Dilaurate (C32H64O4Sn) and Organic Zinc Complex containing 19‑23 % Zn.

The product set focuses on catalytic and stabilising agents used in polymer production, especially PVC and polyurethane systems. Organotin catalysts such as Dibutyltin Dilaurate, Butylchlorodihydroxytin and Chelate Tin are typical tin‑based stabilisers that function at low concentrations. The organic zinc catalysts, with zinc content between 19 % and 23 %, are commonly employed as secondary stabilisers or cross‑linking agents. Dimethyldineodecanoatetin is an organotin carboxylate used for its hydrolytic stability. The range therefore covers both primary and secondary catalyst chemistries required in plastics manufacturing.

Product Range and Specialties of NanTong HaoTai Products & Chemicals Co., Ltd.

The catalogue groups products by metal‑based catalyst type: organotin compounds (Monobutyltin Oxide, Stannous Octoate, Dibutyltin Dilaurate, Butylchlorodihydroxytin, Chelate Tin, Dimethyldineodecanoatetin) and organic zinc complexes. In the wider industry, organotin stabilisers are graded by tin content (typically 27‑30 % for chelates) and by purity, often specified as ≥99 % metal content. Zinc catalysts are usually described by zinc percentage and by the organic ligand structure; the 19‑23 % Zn range matches common commercial grades used as secondary stabilisers. Buyers often request material safety data sheets (SDS) and assay certificates that confirm these percentages. Typical specifications for these chemicals include moisture content below 0.5 %, flash point above 120 °C for liquid catalysts, and particle size under 50 µm for powdered forms. Packaging for bulk chemicals from China often uses 25 kg drums, 200 kg IBC totes or 20 ft containers, depending on the product’s physical state. The HS codes listed (2931.90 for most organotin compounds, 2931.69 for tin chelates, and 3824.99 for organic zinc complexes) align with customs classifications used worldwide for polymer additives.

Trade and Export Information - NanTong HaoTai Products & Chemicals Co., Ltd.

China is a leading exporter of organometallic catalysts, supplying Europe, North America and Southeast Asia with bulk shipments. HS Chapter 29 covers organic chemicals such as organotin compounds, while Chapter 38 includes organic zinc complexes; customs authorities frequently request certificates of analysis, REACH registration evidence and compliance with ISO 9001 quality systems for these codes. Export logistics typically involve free‑on‑board (FOB) Shanghai or Ningbo ports, with buyers arranging CIF to their destination ports. Standard container loading follows 20 ft or 40 ft containers, with drums stacked according to IMDG regulations for hazardous liquids. Importers of these catalysts generally require conformity to REACH (for EU markets) and TSCA (for the United States), as well as RoHS compliance when the end‑product is an electronic component. Inspection regimes often include pre‑shipment sampling under the Shanghai Inspection and Quarantine (CIQ) system, and post‑arrival lab testing for tin or zinc content. The supplier’s trust tier is listed as "harbor", indicating that the platform has verified basic business credentials, but buyers should still verify third‑party certifications before finalising contracts.

Sourcing from NanTong HaoTai Products & Chemicals Co., Ltd. - Buyer Guidance

When sourcing organotin or zinc catalysts from NanTong HaoTai, request a full material safety data sheet (SDS) and a recent certificate of analysis that lists tin or zinc percentage, moisture content and impurity limits. Verify that the product complies with REACH registration (EU) or TSCA (US) if the final application is subject to those regulations; the supplier may provide registration numbers or a statement of compliance. Confirm packaging details - drums, IBCs or bulk bags - and ensure the chosen Incoterm (e.g., FOB Shanghai) matches your logistics plan. Typical minimum order quantities for these catalyst chemicals range from 500 kg to 1 tonne, with lead times of 30‑45 days from order confirmation, depending on production scheduling and export documentation. Request a sample batch for laboratory validation of catalyst performance before committing to a full shipment.

What HS codes apply to the organotin catalysts listed by NanTong HaoTai?

Most organotin catalysts such as Dibutyltin Dilaurate, Butylchlorodihydroxytin and Dimethyldineodecanoatetin fall under HS code 2931.90, while the tin chelate is classified under 2931.69.

Which certifications should a buyer verify for these chemicals?

Buyers should request REACH registration proof for EU markets, TSCA confirmation for the United States, and any ISO 9001 quality‑management certificates the supplier can provide.

What typical purity levels are expected for the zinc catalyst?

Commercial organic zinc catalysts are usually supplied with zinc content between 19 % and 23 % and overall metal purity of 99 % or higher, as indicated in the catalogue.

How are these chemicals usually packaged for export?

Bulk organotin and zinc catalysts are commonly packed in 25 kg steel drums, 200 kg intermediate bulk containers, or bulk shipments in 20 ft or 40 ft containers, complying with IMDG rules for hazardous liquids.

What is a common minimum order quantity for these catalyst products?

Typical minimum order quantities range from 500 kg to 1 tonne, depending on the specific catalyst and the buyer’s logistics capabilities.

What lead time should a buyer expect for a new order?

Lead times generally range from 30 to 45 days after order confirmation, allowing for production scheduling and export documentation.

Are there standard tests buyers should request for quality assurance?

Buyers commonly request an assay report showing tin or zinc percentage, moisture content, and impurity limits, as well as a full SDS for safety compliance.

Which global regions most frequently import these types of catalysts from China?

Europe, North America and Southeast Asian countries are the primary import markets for Chinese organotin and zinc catalysts, driven by demand in the plastics and polymer industries.
