Import Domed Opaque Quartz Tube — Buy in Bulk from Supplier in China

The product is a domed opaque quartz tube supplied by Highborn International Company, fabricated from fused quartz and offered in a range of custom shapes including cut, grind, frost, dome and bend. While the listing does not give exact dimensions, the tubes can be produced to customer‑specified lengths and diameters, and are designed for high‑temperature and chemically aggressive environments. The material’s intrinsic purity provides excellent optical transmission and thermal stability.

Quartz tubes of this type typically have an inner diameter between 10 mm and 200 mm and wall thickness from 1 mm to 5 mm, with dimensional tolerances of ±0.1 mm (typical). They meet standard ASTM C973 for fused quartz and can withstand temperatures up to 1100 °C (typical). The opaque finish reduces light transmission, making the tubes suitable for applications where shielding is required while still retaining quartz’s resistance to thermal shock.

Target buyers include manufacturers of lighting fixtures, scientific instrumentation and optical devices that need durable, high‑purity quartz components. Highborn International Company ships from China and states that flexible MOQ options and competitive terms are available, though exact quantities and lead times must be confirmed. Importers should discuss Incoterms, payment methods and any required certifications such as ISO or CE with the supplier before finalising the purchase.

Highborn International Company is listed with a harbor trust tier and an imported supplier tier. Their address is in Lianyungang, Jiangsu Province, China, indicating that production and dispatch are managed from this location. The profile shows they specialise in quartz and glass components for industrial use.

The supplier’s public information does not disclose specific certifications, MOQ, lead‑time or revenue figures, and the response rate is recorded as 0 %. Buyers should therefore request detailed quotations, quality certificates and production schedules directly from Highborn to assess suitability. Their verification signals are limited to the trust tier, with no recorded response performance.
