About Hengda Silane Techonology Company Limited - Agriculture Supplier in China

China‑based Hengda Silane Techonology Company Limited lists five distinct organosilane compounds in its current catalogue. The five items are Bis3-(triethoxysilyl)propyl]amine, γ‑Aminopropylmethyldiethoxysilane, Aminopropylmethyldimethoxysilane, N‑Phenyl‑γ‑aminopropyltrimethoxysilane and Gamma‑aminopropyltriethoxysilane. Each entry is presented under the Agriculture category, reflecting the common use of silane coupling agents as seed‑treatment additives, soil conditioners and crop‑protectant enhancers. The catalogue does not provide HS‑code numbers, so the listing focuses on chemical names and functional groups.

The listed compounds belong to the organosilane family, characterized by a silicon atom bonded to organic substituents and alkoxy groups. In agricultural applications these agents improve adhesion of fertilizers, pesticides and biostimulants to plant surfaces and soil particles. Typical specifications for such silanes include purity levels of 95 % - 99 %, moisture content below 0.5 % and a defined pH range for aqueous solutions. Hengda’s five products therefore cover a range of functional groups - amine, phenyl and alkoxy variations - providing buyers with multiple options for formulation development.

Product Range and Specialties of Hengda Silane Techonology Company Limited

The catalogue offers five aminosilane variants, each differing in the number and type of alkoxy groups attached to the silicon center. Bis3-(triethoxysilyl)propyl]amine contains three triethoxysilyl groups, while Gamma‑aminopropyltriethoxysilane carries a single triethoxysilyl moiety; the others fall between these extremes with mixed ethoxy/methoxy substitution. In the broader silane market, buyers usually request a minimum purity of 98 % for agricultural formulations, with certified analysis confirming the exact alkoxy composition and residual amine content. Common grades are designated by the ratio of ethoxy to methoxy groups, which influences hydrolysis rate and coupling efficiency. Packaging is typically in 25 kg or 50 kg drums, and bulk shipments may use 1 ton intermediate bulk containers (IBCs).

Trade and Export Information - Hengda Silane Techonology Company Limited

China is a major exporter of organosilane chemicals, and shipments from eastern ports such as Shanghai or Ningbo frequently serve buyers in Southeast Asia, Europe and North America. The HS‑code chapter for organosilicon compounds is 2925, with many aminosilanes falling under sub‑heading 2925.90 (other organosilicon compounds). Importing countries often require REACH registration for the EU, TSCA compliance for the United States, and an ISO 9001 quality management system audit for the supplier. Standard logistics involve loading drums onto 20‑ft or 40‑ft containers, with FOB Shanghai or CIF Rotterdam as common Incoterms. Documentation usually includes a commercial invoice, packing list, Certificate of Origin, Material Safety Data Sheet (MSDS) and, where required, a test report confirming purity and moisture content.

Regulatory scrutiny for agricultural chemicals emphasizes residue limits and environmental safety. Buyers typically request third‑party analysis certificates (e.g., from SGS or Intertek) to verify that the silane meets the applicable limits for heavy metals and volatile organic compounds. Chinese exporters often provide a Certificate of Analysis (CoA) aligned with the International Organization for Standardization (ISO) 17025 laboratory accreditation, which facilitates acceptance in regulated markets.

Sourcing from Hengda Silane Techonology Company Limited - Buyer Guidance

When sourcing from Hengda, buyers should request a current Certificate of Analysis that lists purity, moisture, pH and heavy‑metal content for each silane. A Material Safety Data Sheet (MSDS) is essential to assess handling, storage and transport requirements, especially because many aminosilanes are moisture‑sensitive and may release ethanol during hydrolysis.

Confirm the packaging format - standard 25 kg or 50 kg steel drums are typical - and verify that the drums are suitable for bulk transport without contamination. Buyers often ask for a small pre‑shipment sample (e.g., 500 g) to run in‑house compatibility tests before placing a larger order.

Check that the supplier can provide any required regulatory documentation, such as REACH registration numbers for EU import or TSCA notices for the US. Ensuring that these certificates are up to date reduces customs delays and facilitates downstream product registration.

What purity levels are typical for the aminosilanes listed by Hengda?

The catalogue does not state purity, but in the organosilane market buyers usually require 95 % - 99 % purity, documented by a Certificate of Analysis issued by an ISO 17025‑accredited laboratory.

Which packaging formats are available for these silane chemicals?

Standard packaging for bulk organosilanes includes 25 kg or 50 kg steel drums. For larger orders, intermediate bulk containers (IBCs) of up to 1 ton are also common.

What HS‑code family do the listed products fall under?

Aminosilanes are classified under HS Chapter 29, specifically heading 2925 for organosilicon compounds, with many falling under sub‑heading 2925.90 (other organosilicon compounds).

What regulatory documents should a buyer request before import?

Buyers should request a current Certificate of Analysis, an MSDS, and any regional compliance certificates such as REACH registration for the EU or TSCA notice for the United States.

What are typical lead times for shipping these silanes from China?

Lead times depend on order size and production schedule, but standard bulk orders from Chinese manufacturers usually require 4 - 6 weeks from order confirmation to shipment.

Is a minimum order quantity (MOQ) specified for these products?

While the catalogue does not list an MOQ, bulk silane chemicals are commonly sold with a minimum order of one 25 kg drum, with larger volumes negotiated per container load.

Which Incoterms are most frequently used for exporting these chemicals?

Exporters from China typically quote FOB Shanghai or Ningbo, and many buyers prefer CIF to a European or North American port for convenience.

How can a buyer obtain a sample for testing?

Buyers can request a 500 g sample, which the supplier will ship in a sealed drum along with the corresponding Certificate of Analysis and MSDS for preliminary evaluation.
