About Laizhou Chiyuan Industry And Trade Co., Ltd - Resin Supplier in China

Laizhou Chiyuan Industry And Trade Co., Ltd operates from China and currently lists five active products in its catalogue. The listed items span two main categories: petroleum‑based resins and extrusion machinery, reflecting a focus on polymer additives and processing equipment. The resin portfolio includes C9 hydrogenated hydrocarbon petroleum resin, a combined C5 & C9 copolymer petroleum resin, and water‑white rosin resin, each identified without specific HS codes in the source data. The machinery segment comprises a 1000 mm single‑screw extruder, a PVC twin‑screw extruder (HS code 8477.80, steel housing with wear‑resistant alloy screw elements), and the same single‑screw model listed under a generic “Plastic Machine” label.

The supplier’s product count of five aligns with a narrow, specialised offering rather than a broad commodity catalog. All resin entries are described by their hydrocarbon chain length (C5, C9) and hydrogenation level, while the extruder models are defined by screw configuration and intended polymer type (PVC). The presence of an HS code for the PVC twin‑screw extruder places it within chapter 84 of the Harmonized System, covering machine tools for working plastics. No additional product attributes such as grades or performance metrics are provided in the source material.

Product Range and Specialties of Laizhou Chiyuan Industry And Trade Co., Ltd

The resin selection consists of C9 hydrogenated hydrocarbon petroleum resin, a C5 & C9 copolymer petroleum resin, and water‑white rosin resin. In the broader industry, C9 resins are typically classified as low‑softening, high‑tack tackifiers used in adhesives and rubber compounding, often meeting ASTM D1238 melt flow specifications and ICUMSA colour grades for purity. C5‑C9 copolymers combine the low‑temperature flexibility of C5 with the tack of C9, and buyers usually request gel content below 2 % and a softening point around 70‑80 °C. Water‑white rosin resin is a refined rosin with low colour (often ≤ 10 ICUMSA) and is used in printing inks and coatings where clarity is important. The extrusion equipment includes a 1000 mm single‑screw extruder, typically rated for output between 30‑80 kg/h depending on screw design, and a PVC twin‑screw extruder, which in industry is often specified with a screw L/D ratio of 20‑30 and a barrel temperature range of 150‑190 °C for PVC processing. Standard specifications for such machines include a motor power of 7‑15 kW, stainless‑steel or alloy screw elements for wear resistance, and modular die assemblies for product profile flexibility.

Trade and Export Information - Laizhou Chiyuan Industry And Trade Co., Ltd

China is a major exporter of petroleum‑based tackifier resins and plastic processing machinery. Resins of the C5‑C9 family are commonly shipped under HS chapter 27 (organic chemicals) and are subject to phytosanitary certificates only when containing natural rosin, while PVC extrusion machines fall under HS 8477.80, which requires compliance with the EU Machinery Directive and, for many markets, CE marking or equivalent safety certification. Typical import destinations include the United States, Western Europe, and Southeast Asian manufacturing hubs, where buyers look for ISO 9001 quality management and, for resins, ASTM or ISO purity test reports. Extruder shipments are usually packed in 20‑ft or 40‑ft containers with steel frame crating, and freight terms such as CIF Shanghai are standard. Export documentation often includes a commercial invoice, packing list, bill of lading, and, where required, a test certificate confirming melt flow index, softening point, and colour specifications.

Sourcing from Laizhou Chiyuan Industry And Trade Co., Ltd - Buyer Guidance

When evaluating Laizhou Chiyuan’s resin products, request a material safety data sheet (MSDS), a recent laboratory analysis covering melt flow index, softening point, colour (ICUMSA) and gel content, and any third‑party test report that matches the intended application. For the PVC twin‑screw extruder, ask for the machine’s technical data sheet, CE or equivalent safety certification, motor power rating, L/D ratio, and details of the wear‑resistant alloy screw elements. Verify that the HS code 8477.80 matches the quoted machine configuration and that the packaging plan includes sufficient crating to protect steel housings during sea freight. Typical minimum order quantities for resins are 500 kg per grade, while extruder units are generally sold on a single‑unit basis with lead times of 30‑45 days after receipt of a pro‑forma invoice and confirmation of payment terms.

What resin grades are listed by Laizhou Chiyuan Industry And Trade Co., Ltd?

The catalogue lists C9 hydrogenated hydrocarbon petroleum resin, a combined C5 & C9 copolymer petroleum resin, and water‑white rosin resin. Industry buyers usually verify melt flow index, softening point and colour (ICUMSA) for these grades.

Is an HS code provided for any of the products?

Yes, the PVC twin‑screw extruder is assigned HS code 8477.80, which covers plastic extrusion machines with a screw drive.

What specifications should a buyer request for the PVC twin‑screw extruder?

Request the machine’s technical data sheet, motor power (kW), screw L/D ratio, barrel temperature range, and safety certifications such as CE or ISO 9001 compliance.

Which certifications are typically required for petroleum‑based resins?

Buyers often ask for ISO 9001 quality management certification and laboratory test reports that meet ASTM D1238 (MFI) and colour standards like ICUMSA 45‑70, depending on end‑use.

What are common packaging methods for the extrusion machines?

Machines are usually crated in wooden frames with internal foam padding, placed in 20‑ft or 40‑ft containers, and sealed to protect steel housings from corrosion during sea transport.

What are typical lead times for the listed products?

Resin batches generally require 2‑4 weeks for production and shipment, while complete extruder units are commonly quoted with a 30‑45 day lead time after order confirmation.

Which markets import these types of products from China?

Major import markets include the United States, Germany, Italy, Japan and Thailand, where the resins are used in adhesives, rubber compounds and inks, and the extrusion machines serve plastic film, pipe and profile manufacturers.

What documentation should be verified before finalizing an order?

Verify the commercial invoice, packing list, bill of lading, material safety data sheet for resins, and a test certificate or CE mark for the extrusion equipment to ensure compliance with destination regulations.
