Rcna-Center For Chinese Learning offers Gum Rosin, also known as colophony, produced by heating fresh pine resin to remove volatile terpenes. The resin is supplied from the Shandong facility on Yantai Road, Rizhao, and carries the CAS identifier 8050-09-07. The supplier highlights that the material is semi‑transparent and can range in colour from yellow to near‑black.
Typical industrial grades contain 68-78 % abietic acid, which influences tack and film‑forming ability. Melting behaviour falls between 100 °C and 108 °C, fitting conventional melt‑processing lines. Standard purity levels reach 94 % or higher, and moisture is kept below 0.6 % to prevent degradation. The product is delivered in galvanized iron drums with a net weight of 240 kg per drum, a common bulk packaging format.
Gum Rosin from this source is used in adhesives, inks, rubber compounding and coating formulations. Importers such as adhesive manufacturers, paint producers and rubber mills frequently source this grade. Because the listing does not specify MOQ or payment terms, buyers should request those details directly from the supplier. Sea freight from the nearest Chinese ports is the usual route, with flexibility to negotiate Incoterms.

Before confirming a purchase, request the latest safety data sheet and any applicable quality certificates, such as ISO 9001 or relevant Chinese standards. Verify that the colour and purity specifications match your formulation requirements and that the resin originates from the stated Shandong facility.
Logistics for Gum Rosin from Rizhao typically involve loading the 240‑kg drums onto container vessels at the nearest Chinese port. Ask the supplier which Incoterms they propose and whether they can arrange door‑to‑door delivery or provide freight forwarding assistance. Payment terms are not listed, so negotiate a clear schedule, for example a letter of credit or T/T after document presentation.
Arrange an independent inspection or request a pre‑shipment sample to validate colour, acid content and moisture level. Ensure the supplier can supply a detailed packing list, batch number and certificate of analysis for customs clearance. These checks help avoid receiving off‑spec material and streamline the import process.
