About Ningbo Yuyao Langchi Plastic Factory - Packaging Items & Containers Supplier in China

Ningbo Yuyao Langchi Plastic Factory operates in the Zhejiang province of China, specifically in the Ningbo‑Yuyao industrial zone. The catalogue currently lists five distinct products, covering hose, tube and specialty tubing applications across agriculture, flange and packaging categories. All items are manufactured from engineering thermoplastics such as Nylon 6, Nylon 12, HDPE, and PTFE, and are classified under HS chapter 40 for plastics. The supplier’s product list is organized by material families and intended end‑uses rather than by broad marketing labels. The factory’s trust tier is recorded as “harbor,” indicating a recognized level of reliability in trade platforms.

The first product, D.o.t. Air Brake Coiled Hose Spring Brake Hose, is recorded under HS code 4009.11 and is produced from either Nylon 6 (PA6) or Nylon 12 (PA12). The remaining four entries are a medical‑grade PTFE tube, a flexible HDPE hose/tube/pipe, a customized specialty tubing, and a static‑dissipative anti‑static air tube. Each item is described only by material type and generic application, with no additional performance specifications disclosed in the source data.

Product Range and Specialties of Ningbo Yuyao Langchi Plastic Factory

The catalogue covers five polymer‑based conduit products. The coiled brake hose uses standard nylon grades that typically provide tensile strengths between 70 - 90 MPa and operating temperatures from - 40 °C to +120 °C. Medical‑grade PTFE tubing is usually supplied in ISO 1101‑compliant dimensions, with purity levels above 99.9 % and a continuous service temperature up to 260 °C. Flexible HDPE hoses are commonly produced with SDR (Standard Dimension Ratio) classifications such as SDR 11 or SDR 13, offering pressure ratings from 1.0 MPa to 3.0 MPa and resistance to chemicals used in agricultural irrigation. Customized specialty tubing can be fabricated to client‑specified inner diameters ranging from 2 mm to 25 mm, wall thicknesses of 0.5 mm to 3 mm, and may meet ASTM D3350 for HDPE or ASTM D638 for nylon. Static‑dissipative anti‑static air tubes are typically formulated to achieve surface resistivity between 10⁶ Ω·cm and 10⁹ Ω·cm, satisfying IEC 61340‑5‑1 requirements for electrostatic discharge control.

Trade and Export Information - Ningbo Yuyao Langchi Plastic Factory

China remains one of the largest exporters of polymer tubing and hose products, with major import destinations in Southeast Asia, the European Union, and North America. HS chapter 40 (plastics) and the specific sub‑heading 4009.11 for coiled hoses are routinely inspected under the China Inspection and Quarantine (CIQ) system and may require a Certificate of Conformity for markets that enforce REACH or FDA regulations. Buyers typically request material safety data sheets (MSDS), third‑party test reports for pressure and temperature performance, and compliance certificates such as ISO 9001 or ISO 14001 when these are not already held by the exporter. Shipping is usually arranged in 20‑foot or 40‑foot containers, with hoses and tubes packed in bulk on pallets or in wooden crates, protected by polyethylene film to prevent moisture ingress.

Sourcing from Ningbo Yuyao Langchi Plastic Factory - Buyer Guidance

When evaluating this supplier, buyers should request a detailed technical data sheet for each polymer, confirming the exact nylon grade (PA6 or PA12), HDPE SDR class, or PTFE purity level. Test reports for burst pressure, tensile strength, and static‑dissipative surface resistivity should be compared against industry standards such as ISO 527 for tensile testing and IEC 61340‑5‑1 for antistatic performance. Samples are advisable to verify dimensional tolerances, especially for customized tubing where inner diameter and wall thickness can vary. Verify that the exporter can provide any required regulatory documents - e.g., FDA 510(k) for medical‑grade PTFE or REACH registration for EU shipments - before confirming a purchase order.

What material is used in the D.o.t. Air Brake Coiled Hose?

The brake hose is manufactured from either Nylon 6 (PA6) or Nylon 12 (PA12), both of which are high‑strength polyamides commonly used for hydraulic and pneumatic applications.

Does the medical‑grade PTFE tube meet FDA requirements?

The catalogue lists the tube as medical grade, which typically implies compliance with FDA 21 CFR 820. Buyers should request the supplier’s FDA‑registration or a compliance certificate to confirm suitability.

What pressure rating can be expected from the flexible HDPE hose?

HDPE hoses are usually offered in SDR 11 or SDR 13, delivering continuous pressure ratings between 1.0 MPa and 3.0 MPa. Specific rating should be verified with the supplier’s test report.

Can the specialty tubing be produced to custom dimensions?

Yes, the “Plastic Customized Tube Specialty Tubing” entry indicates the ability to manufacture to client‑specified inner diameters and wall thicknesses, typically within 2 mm to 25 mm diameter ranges.

What is the static‑dissipative performance of the anti‑static air tube?

Static‑dissipative tubing is generally designed to achieve surface resistivity between 10⁶ Ω·cm and 10⁹ Ω·cm, meeting IEC 61340‑5‑1 standards for electrostatic discharge control.

Which HS codes apply to the products in this catalogue?

The coiled brake hose is listed under HS code 4009.11. The remaining items fall under broader HS chapter 40 for plastics, but specific sub‑headings depend on the exact polymer composition and product form.

What packaging format is used for shipping these hoses and tubes?

Export shipments are typically packed in bulk on pallets or in wooden crates, wrapped in polyethylene film to protect against moisture, and loaded into 20‑ft or 40‑ft containers.

What documentation should a buyer request before placing an order?

Buyers should ask for material safety data sheets, third‑party test reports for pressure and tensile performance, any applicable regulatory certificates (e.g., FDA, REACH), and the supplier’s export declaration for HS code verification.
