Import Bitumen 60/70 40 /50, 85/100, 120/150, 200/300 — Buy in wholesale FOB from Supplier in China

Shandong Longtaili Science And Technology Co.,ltd. supplies a portfolio of penetration-grade bitumens from its base in Qingdao, Shandong Province, China, encompassing 60/70, 40/50, 85/100, 120/150, and 200/300 grades for diverse climatic and traffic conditions. The 40/50 grade represents a hard paving bitumen for tropical highways and airport runways, while the 200/300 grade offers maximum softness for cold-climate surface dressing and crack-sealing applications. Each grade is characterised by needle penetration at 25 degrees Celsius, softening point, and ductility, with the supplier providing detailed test data for 60/70 and 80/100 grades per ASTM methods. The bitumen is packaged in new cold-rolled steel drums of 0.50 or 0.60 mm thickness, with precise dimensions of 500 mm diameter, 980 mm height, and 180 kg net weight per drum.

The supplier's disclosed specifications for 80/100 grade show specific gravity at 25/25 degrees Celsius of 1.01 to 1.05, softening point 45-52 degrees Celsius, ductility at 25 degrees Celsius of 100 cm minimum, loss on heating of 0.5 percent weight maximum, drop in penetration after heating of 20 percent maximum, flash point of 225 degrees Celsius minimum, and solubility in trichloroethylene of 99.5 percent weight minimum. For the 60/70 grade, specific gravity ranges 1.01 to 1.06, softening point 49-56 degrees Celsius, loss on heating 0.2 percent maximum, and flash point 250 degrees Celsius minimum. These values align with standard ASTM D-70, D-5, D-36, D-113, D-6, D-92, and D-4 test protocols, indicating laboratory-controlled production. Organic matter insoluble in carbon disulfide is limited to 0.2 percent weight maximum, and the spot test must be negative, screening out cracked residues and inferior feedstocks.

Buyers range from national road authorities and provincial transport bureaus to private asphalt mix producers and waterproofing membrane manufacturers. The 40/50 and 60/70 grades suit dense-graded hot-mix asphalt for heavy-duty pavements, while 85/100, 120/150, and 200/300 grades find use in open-graded mixes, surface treatments, and cutback bitumen production. Shandong Longtaili's Qingdao location offers port access for containerised drum shipments and potential bulk tanker loading. Importers should match grade selection to their country's climatic zone per pavement design standards, confirm drum specifications for container loading calculations, and verify that the supplier's quality control documentation accompanies each shipment.

Shandong Longtaili Science And Technology Co.,ltd. operates from No.34 Guantao Road, Shibei District, Qingdao City, Shandong Province, China, placing it within a major northern Chinese industrial and port city with established petrochemical and shipping infrastructure. The company holds a harbor trust tier classification, with zero recorded response rate and zero average response hours, indicating no recent platform engagement. The listing presents detailed technical specifications and packaging parameters, suggesting either direct manufacturing involvement or close association with a refinery or blending facility capable of ASTM-compliant testing. Buyers should independently verify business registration in Shandong, tax compliance status, and whether the company holds ISO 9001 or equivalent quality management certification.

The supplier profile does not disclose year of establishment, registered capital, number of employees, annual bitumen throughput, or named refinery partnerships. No client references, export license details, or past shipment records are provided. The scientific and technology designation in the company name may indicate research and development activities, or it may be a standard naming convention in China without operational significance. Importers should request a business license, export licence, and factory audit report, and verify whether Shandong Longtaili owns blending tanks, laboratory facilities, or merely trades third-party product. Direct factory inspection in Qingdao is advisable before committing to volume contracts.
