About Shijiazhuang Green Bridge Trading Co., Ltd. - Oxalic Acid Supplier in China

China, specifically the city of Shijiazhuang in Hebei province, hosts the supplier Shijiazhuang Green Bridge Trading Co., Ltd., which currently lists five active chemical products. The catalogue includes oxalic acid, pentaerythritol, zinc oxide, sodium metabisulphite (HS code 2832.30), and iron oxide. These items fall under the broader categories of Oxalic Acid, Zinc Oxide, Chemicals & Allied Products, and Iron Oxide as indicated in the supplier’s top categories. Each product is presented without additional specifications such as purity or packaging within the public listing. The supplier is classified as an imported tier with a harbor trust rating.

Oxalic acid is listed as a single product without a disclosed HS code, reflecting its classification under chapter 29 for organic acids. Pentaerythritol appears as a polyol used in resin manufacturing, again without HS code detail. Zinc oxide is recorded as a standalone item, commonly used in rubber vulcanisation and pigment applications. Iron oxide is listed as a colorant material, typically supplied as Fe2O3 pigment. The sodium metabisulphite entry includes the HS code 2832.30, aligning it with the sulphite family of inorganic chemicals.

Product Range and Specialties of Shijiazhuang Green Bridge Trading Co., Ltd.

The supplier’s catalogue covers oxalic acid, pentaerythritol, zinc oxide, sodium metabisulphite and iron oxide. In the chemical trade, oxalic acid is usually supplied in technical grade (≥95 % purity) and analytical grade (≥99 % purity) for applications ranging from metal cleaning to textile bleaching. Pentaerythritol is commonly offered at 99 % purity and is used as a polyol in epoxy resin and lubricant formulations. Zinc oxide is typically produced with a purity of 99.5 % or higher, particle sizes ranging from 0.2 to 5 µm, and is employed in rubber, cosmetics and pigment markets. Sodium metabisulphite is normally supplied at 98‑99 % purity, packaged in 25 kg drums or 1 ton bulk bags, and serves as a preservative and reducing agent. Iron oxide pigments are graded by colour index (e.g., CI 77007) and are supplied with particle sizes of 0.1‑3 µm for coating and paint applications. Buyers often request certificates of analysis for each batch to confirm these specifications.

Trade and Export Information - Shijiazhuang Green Bridge Trading Co., Ltd.

China is a leading exporter of inorganic and organic chemicals, and the products listed fall under HS chapters 28 (inorganic chemicals) and 29 (organic chemicals).

Sourcing from Shijiazhuang Green Bridge Trading Co., Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request a current Certificate of Analysis (CoA) for each chemical, specifying purity, moisture content and any impurity limits. A full Safety Data Sheet (SDS) complying with GHS standards should be obtained to meet regulatory requirements in the destination country. Verify that the product meets any regional certifications such as REACH (for EU) or EPA (for US) before finalising the order, and confirm packaging details - e.g., 25 kg drums for sodium metabisulphite or 1 ton bulk bags for zinc oxide - to align with logistics plans.

What grades are typically available for the chemicals listed by the supplier?

Oxalic acid is commonly offered in technical (≥95 % purity) and analytical (≥99 % purity) grades. Pentaerythritol, zinc oxide, sodium metabisulphite and iron oxide are usually supplied at ≥99 % purity, with zinc oxide and iron oxide also defined by particle‑size specifications.

Which HS codes apply to the supplier’s products?

The only HS code provided in the catalogue is 2832.30 for sodium metabisulphite. Oxalic acid, zinc oxide, pentaerythritol and iron oxide are generally classified under HS 2915‑13, 2815‑90, 2915‑20 and 2815‑90 respectively, but the supplier’s specific listings do not include those codes.

What documentation should a buyer request before purchasing?

Buyers should request a Certificate of Analysis (CoA) for each batch, a full Safety Data Sheet (SDS) complying with GHS, and any relevant regulatory certificates such as REACH registration or ISO 9001 if required by the destination market.
