About Wenzhou Jinyuan Chemicals Co., Ltd. - Industrial Chemicals Supplier in China

Wenzhou Jinyuan Chemicals Co., Ltd. is based in Wenzhou, Zhejiang Province, China, and currently lists five active pigment products. The portfolio includes Pigment red 122, Pigment red 177 (c.I. designation), Pigment red 202, Pigment red 207, and Pigment yellow 110. All items fall under the industrial chemicals category and are classified as colorants used in manufacturing. The company is recorded as an imported supplier with a harbor trust tier. The catalogue does not provide additional product specifications.

The listed pigments are typical members of the HS chapter 32 chemical products, commonly grouped under HS code 3206 for pigments and extenders. In the global market these pigments are supplied to coating manufacturers, plastic processors, and textile printers who require consistent tinctorial strength and particle‑size distribution. Typical industry grades for red pigments range from high‑purity (>95 % pigment content) to specialty grades with modified surface treatments for dispersibility. Yellow pigment CI 110 is often specified with a minimum lightfastness rating of 8 on the ASTM scale. Buyers usually request compliance documents such as REACH registration and safety data sheets for each pigment.

Product Range and Specialties of Wenzhou Jinyuan Chemicals Co., Ltd.

The catalogue lists five distinct pigment products: Pigment red 122, Pigment red 177, Pigment red 202, Pigment red 207, and Pigment yellow 110. These pigments are standard organic or inorganic colorants identified by their CI (Color Index) numbers and are widely used in coatings, plastics, and printing inks. Industry practice separates pigments by hue, tinctorial strength (often expressed in % reflectance or tinting strength), and particle size, which for these types typically falls between 0.5 µm and 3 µm.

In the broader pigment market, red pigments such as CI 122 and CI 177 are often produced with iron‑oxide or quinacridone bases, offering grades with purity levels of 95 % to 98 % and moisture content below 0.5 %. Yellow pigment CI 110 is an arylide yellow commonly supplied with a minimum lightfastness of 8 and a typical oil absorption of 90 - 120 g per 100 g pigment. Buyers frequently specify limits on heavy‑metal content (e.g., lead <10 ppm) and request batch‑wise analytical reports conforming to ISO 14040.

Trade and Export Information - Wenzhou Jinyuan Chemicals Co., Ltd.

China is a major exporter of organic and inorganic pigments, and shipments from the Zhejiang region are routinely directed to coating and plastics manufacturers in Southeast Asia, the European Union, and the United States. HS chapter 32 codes, particularly 3206.20 for inorganic pigments, are subject to customs inspections that verify REACH registration for the EU and TSCA compliance for the US. Export shipments are commonly packed in 20‑ft or 40‑ft containers using 25 kg paper bags placed inside wooden crates or metal drums, with moisture barriers to preserve pigment stability.

Importing parties generally require a Certificate of Analysis, a Safety Data Sheet, and a REACH registration number before customs clearance. For high‑value pigment batches, third‑party inspection agencies may provide an assay report according to ISO 9001 quality‑management standards. Incoterms such as FOB Wenzhou or CIF destination port are typical for bulk pigment orders, with freight forwarders handling the containerization of the dry, non‑hazardous material.

Sourcing from Wenzhou Jinyuan Chemicals Co., Ltd. - Buyer Guidance

When sourcing pigments from Wenzhou Jinyuan Chemicals, buyers should request the latest Certificate of Analysis that details pigment content, particle‑size distribution, moisture, and heavy‑metal limits. A pre‑shipment sample evaluated against ISO 3668 (color fastness) and ASTM D523 (color strength) helps verify that the product meets the required hue and performance.

Buyers should also confirm that the supplier can provide REACH registration documentation for EU shipments and a TSCA notice of compliance for US imports. Verifying the packaging format (25 kg paper bag, inner liner, outer crate) and the lead time for container loading (typically 30 - 45 days from order confirmation) reduces risk of delays. Where possible, arrange a third‑party inspection at the loading port to confirm quantity and conformity before vessel departure.

What pigment colors does the supplier offer?

The supplier lists five pigments: Pigment red 122, Pigment red 177, Pigment red 202, Pigment red 207, and Pigment yellow 110. Each product is identified by its standard CI designation and is intended for industrial coloring applications.

Are safety data sheets available for these pigments?

Yes, standard Safety Data Sheets covering handling, storage, and hazard classification can be requested for each pigment. The SDS will include information on health hazards, first‑aid measures, and environmental precautions.

Which certifications should a buyer verify for Chinese pigment exporters?

Buyers typically request REACH registration for shipments to the European Union and TSCA compliance for the United States. A Certificate of Analysis that follows ISO 9001 quality‑management procedures is also commonly required.

What are common packaging formats for bulk pigments from China?

Bulk pigments are usually packed in 25 kg paper bags, which are placed inside wooden crates or metal drums for stability. The packed units are then loaded into 20‑ft or 40‑ft containers for ocean freight.

What typical lead time should a buyer expect for a full container order?

Lead times generally range from 30 to 45 days from order confirmation to vessel loading, depending on production scheduling and container availability. Early confirmation of specifications and documentation can help keep the schedule within this window.

Which specifications are commonly tested for red and yellow pigments?

Standard tests include tinctorial strength (ASTM D523), lightfastness (ASTM D4303), particle‑size distribution by laser diffraction, moisture content, and heavy‑metal limits such as lead below 10 ppm. Test results are normally presented in the Certificate of Analysis.

How can a buyer ensure the pigment batch complies with import regulations?

The buyer should obtain a recent Certificate of Analysis, REACH or TSCA documentation, and the Safety Data Sheet before shipment. Arranging a third‑party inspection at the port of loading provides additional verification of quantity and conformity prior to vessel departure.
