Buy & Import Caustic Soda from Seng Fat (HK) Ent Ltd. - Wholesale Supply

Seng Fat (HK) Ent Ltd. offers caustic soda in the form of high‑purity sodium hydroxide flakes with a minimum assay of 99 % NaOH, as stated in the product description. The flakes are commonly packed in 25 kg bags and are suitable for bulk import in containerised shipments. This grade is widely used in paper pulping, textile processing, detergent formulation and petroleum refining where a solid alkaline source is required. The supplier highlights that the product complies with standard industrial specifications for purity and physical form.

Typical solid NaOH flakes have a bulk density of about 2.13 g cm‑3 and dissolve readily in water, producing solutions with a pH of roughly 13.5 at 1 % concentration. Standard storage calls for dry, airtight containers kept at 20‑30 °C to avoid moisture uptake, which can cause caking. The material is classified as hazard class 8 (corrosive) and must be handled with appropriate protective equipment and ventilation. Safety data sheets are normally issued on request, detailing handling and emergency measures.

Buyers generally import the product under FOB or CIF terms, loading the 25 kg bags into 20‑ft containers or larger bulk vessels. Since the listing does not disclose minimum order quantity, lead time or payment conditions, interested parties should confirm these parameters directly with Seng Fat (HK) Ent Ltd. Custom packaging or bulk IBC options can be discussed if the buyer’s logistics require it. The high purity of the flakes makes them a preferred choice for manufacturers seeking consistent alkaline performance in chemical synthesis and water treatment.

Sourcing Caustic Soda from Seng Fat (HK) Ent Ltd. - Hong Kong Import Guide

Before placing an order with Seng Fat (HK) Ent Ltd., verify that the NaOH flakes meet the required 99 % purity for your application by requesting a current certificate of analysis and reviewing the material safety data sheet. Confirm that the 25 kg bag packaging aligns with your storage facilities and that the containers are sealed to prevent moisture ingress. Additionally, ensure that any regulatory certifications required by your market can be supplied by the seller.

Discuss the preferred incoterm, such as FOB Hong Kong or CIF Shanghai, and ask the supplier to provide an estimated lead time from order confirmation to vessel departure. Because response rates are not recorded, request a written timeline covering production, quality inspection and dispatch. Payment terms are not disclosed, so negotiate a secure arrangement such as a confirmed letter of credit or advance payment consistent with your company’s risk policy.

Arrange a third‑party pre‑shipment inspection to confirm purity, bulk density and absence of contaminants. Require that the shipment be accompanied by an up‑to‑date MSDS, a certificate of analysis and, where applicable, a compliance certificate for hazardous chemicals. Upon receipt, inspect bag integrity, check for moisture damage and perform a quick pH test on a dissolved sample to verify that the product remains within specification.
