About Ngoc Chau Supplier - Raw Rubber Supplier in Viet Nam

Ngoc Chau Supplier operates from Vietnam and lists six active products in its catalogue. All six entries are variations of natural rubber latex with a high‑ammonia (HA) formulation and a declared dry rubber content (DRC) of 60 %. The product titles include “Natural rubber - HA Latex 60 % DRC of Vietnam”, “Natural Rubber Latex HA 60 % DRC of Vietnam”, “Centrifuged Latex HA/LA 60 % DRC”, “Centrifuged HA Latex 60 % DRC”, “Latex HA 60 % DRC”, and “quality Natural Rubber Latex HA 60 % DRC”. The catalogue does not provide separate HS codes, but the items fall under the natural rubber primary form classification used for raw latex exports. The supplier is listed under the “harbor” trust tier, indicating a moderate level of verification on the platform.

The listed products are all classified under the raw rubber category, specifically natural rubber latex intended for processing into downstream goods such as gloves, medical devices, and adhesives. Each product description emphasizes the HA (high‑ammonia) process, which is a common manufacturing route for latex with a dry rubber content of 60 %. The consistency of the catalogue suggests the supplier focuses on a single grade rather than multiple DRC levels. Buyers can expect the same basic chemical specification across the six listings, differentiated only by marketing descriptors.

Product Range and Specialties of Ngoc Chau Supplier

The catalogue concentrates on HA‑type natural rubber latex at 60 % DRC, a grade widely used for disposable gloves and latex‑based adhesives. In the industry, HA latex at this dry rubber content typically meets ISO 9001 quality management and complies with ASTM D1172 for latex purity, with dry rubber content tolerance of ±1 % and total ammonia nitrogen (TAN) limits below 0.5 % by weight. Common variants include centrifuged versus non‑centrifuged latex; centrifuged latex offers lower microbial load and higher stability, which aligns with the “Centrifuged” entries in the supplier’s list. Packaging for this grade is usually supplied in 200 kg steel drums or bulk containers, allowing 20‑foot containers to hold roughly 10‑12 drums, while 40‑foot containers accommodate 20‑24 drums.

Typical specifications for 60 % DRC HA latex also include a pH range of 10 - 11, viscosity of 150 - 250 cPs at 25 °C, and a protein content below 50 ppm after standard coagulation. Buyers often request a Certificate of Analysis confirming these parameters, as well as microbial limits such as total plate count below 1 000 CFU/mL. The supplier’s focus on a single DRC level simplifies batch comparison, but purchasers should verify whether the product meets any additional standards required for their end‑use, such as EU REACH or US FDA compliance for medical applications.

Trade and Export Information - Ngoc Chau Supplier

Vietnam ranks among the top global exporters of natural rubber latex, with HS chapter 40, specifically HS 4002 90 (natural rubber, raw, in primary forms). Export shipments are commonly directed to the European Union, United States, Japan, South Korea, and neighboring ASEAN markets, where the automotive, medical, and consumer goods sectors drive demand for HA latex. Buyers typically arrange FOB terms from Ho Chi Minh City or Da Nang ports, using 20‑ft or 40‑ft containers that align with the bulk drum packaging described above.

Regulatory requirements for latex imports often include compliance with ISO 9001 quality management, ISO 14001 environmental management, and, for medical‑grade latex, ISO 13485 or FDA 510(k) clearance. Importing countries may also request a Phytosanitary Certificate and a Certificate of Origin to satisfy customs and trade‑agreement preferences. Logistics providers handling latex must observe temperature‑controlled storage (15 - 25 °C) to maintain stability, and safety data sheets (SDS) are mandatory for hazardous chemical classification.

Sourcing from Ngoc Chau Supplier - Buyer Guidance

When sourcing HA latex 60 % DRC from Ngoc Chau Supplier, buyers should request a recent Certificate of Analysis that details dry rubber content, total ammonia nitrogen, pH, viscosity, and microbial limits. Confirmation of any applicable certifications - such as ISO 9001, ISO 14001, or REACH compliance - should be obtained before contract finalisation. Samples are typically provided in 5‑kg drums, allowing verification of physical properties and compatibility with downstream processing.

Potential buyers should also verify packaging integrity, ensuring drums are sealed and labeled according to UN 3485 for hazardous liquids. Minimum order quantities for bulk latex are often set at one metric ton, equivalent to five 200‑kg drums, with lead times ranging from 30 to 45 days after order confirmation. Clarifying Incoterms (e.g., FOB Ho Chi Minh City) and arranging freight forwarder handling of temperature‑controlled containers will help avoid delays at port.

What does the “HA” designation mean in the product names?

HA stands for high‑ammonia latex, a manufacturing process where ammonia is added to stabilize the latex during coagulation. This route typically yields a dry rubber content of around 60 % and is common for products such as disposable gloves.

Why is the dry rubber content (DRC) specified as 60 %?

A 60 % DRC indicates the proportion of solid rubber in the latex after water removal, providing a balance between viscosity and solid content that suits many downstream applications. The industry tolerates a ±1 % variance for this grade.

Are any of the listed latex products centrifuged, and what impact does that have?

Yes, two catalogue entries explicitly mention “Centrifuged”. Centrifugation reduces microbial load and improves stability, making the latex more suitable for medical‑grade end‑uses.

Which certifications should I request before purchasing this latex?

Buyers should ask for ISO 9001 (quality management) and ISO 14001 (environmental management) certificates, as well as any product‑specific compliance such as REACH, FDA 510(k) or ISO 13485 if the latex will be used in medical devices.

What packaging formats and container capacities are typical for this latex?

The standard packaging is 200 kg steel drums. A 20‑ft container can hold roughly 10‑12 drums, while a 40‑ft container can accommodate 20‑24 drums, allowing efficient bulk shipment.

Which regions commonly import Vietnamese HA latex?

Major import destinations include the European Union, United States, Japan, South Korea, and other ASEAN countries, where the automotive, medical and consumer goods sectors drive demand.

What documentation is needed for customs clearance of this product?

Customs usually require a commercial invoice, packing list, Certificate of Origin, and a Certificate of Analysis. For certain markets, a Phytosanitary Certificate and relevant safety data sheets (SDS) are also required.

What are typical minimum order quantities and lead times?

Bulk orders are often set at a minimum of one metric ton (about five 200‑kg drums). Lead times generally range from 30 to 45 days after order confirmation, depending on production scheduling and shipping arrangements.
