Import Brass Tube — Buy in Bulk from Supplier in China

Dingtai Holdings Co., Ltd. supplies brass tubes from Qingdao, Shandong province, positioned as an imported-tier supplier with harbour trust classification. The tubes serve plumbing, HVAC, and automotive systems where corrosion resistance and dimensional precision matter. The source description indicates availability in multiple sizes and wall thicknesses, though exact dimensional data is not stated in the listing. Brass as a material combines copper and zinc, with the ratio determining properties such as machinability, colour, and resistance to dezincification.

The typical brass tube for industrial applications uses alloys in the C26000 to C28000 series, with copper content ranging from 60% to 85% and zinc making up the balance. Standard manufacturing methods include extrusion and drawing, with drawn tubes offering tighter dimensional tolerances and smoother internal surfaces. The source mentions compliance with ASTM standards, a common reference for brass alloy specifications in North American and global trade. ISO quality management certification is also referenced, though the specific standard (such as ISO 9001) is not detailed. Wall thickness typically follows ASTM B135 or EN 12449 classifications, with standard tolerances of plus or minus 5% for drawn tubes in commercial grades.

Buyers for this product include plumbing contractors, refrigeration equipment manufacturers, automotive parts suppliers, and electrical conduit fabricators. The source indicates FOB and CIF as offered Incoterms, with flexible minimum order quantities, though no specific figures are confirmed. Packaging is described as secure for shipment, a standard practice for brass tubes that are typically bundled, capped at ends, and wrapped to prevent surface damage during ocean freight. Buyers should confirm the exact alloy grade, temper (annealed, half-hard, hard), and whether mill test certificates accompany each lot.

Dingtai Holdings Co., Ltd. is located in Qingdao, Shandong province, China, a major port city with established metal processing and export infrastructure. The supplier holds an imported tier classification and harbour trust status on the platform, with a response rate of 0.00% and zero average response hours recorded. These signals suggest limited or no recent engagement through platform messaging, and buyers should treat direct contact as the primary communication channel. The supplier address is confirmed as Qingdao 266700 Shandong China, with no additional branch, factory, or office locations stated in the available profile.

The listing describes the company as offering brass tubes for plumbing, HVAC, automotive, refrigeration, and electrical applications. No manufacturing history, year of establishment, employee count, annual revenue, or named clients appears in the source data. The supplier claims compliance with ISO and ASTM standards, though specific certificates or accreditation numbers are not provided. Buyers should request copies of current mill certificates, ISO registration, and any third-party inspection reports before placing orders. The profile does not indicate whether Dingtai operates its own foundry and extrusion facility or sources finished tubes for resale.
