Import Ballistic Ceramic-Alumina — Buy in Bulk from Supplier in Hong Kong

Spring Sun First Tactical International Co., Ltd. supplies ballistic ceramic-alumina tiles manufactured from 99 percent alumina powder through forming and sintering processes, then laminated with ultra-high molecular weight polyethylene (UHMWPE) into composite armor panels. The alumina ceramic layer provides hardness to fracture and deform projectiles upon impact, while the UHMWPE backing absorbs residual energy through fiber elongation and delamination. These panels are tested to NIJ 0101.06 Level III and Level IV, corresponding to defeat of 7.62x51mm M80 ball ammunition and .30-06 M2 armor-piercing rounds respectively. Tile porosity is controlled to low levels during sintering, as porosity reduction directly correlates with ceramic hardness and multi-hit capability.

The 99 percent alumina composition places this material in the high-purity alumina ceramic category, distinct from lower-grade 85-95 percent alumina ceramics used in industrial wear applications. Sintering at temperatures typically exceeding 1,600°C achieves full density and corundum-phase crystallization, yielding Vickers hardness in the range of 1,500 to 1,700 HV (typical for high-purity alumina armor ceramics). The combination with UHMWPE rather than aramid or fiberglass backing indicates a focus on areal density efficiency, as UHMWPE offers higher specific energy absorption than aramid at equivalent weight. Panel construction may employ monolithic ceramic tiles, mosaic arrays, or overlapping geometries to optimize coverage while managing crack propagation from impact.

Primary applications include personal body armor systems (plate carriers, tactical vests) and vehicle armor kits for military, law enforcement, and private security contractors. The NIJ 0101.06 standard references U.S. law enforcement requirements, though equivalent STANAG 4569 or EN 1063 standards may apply for European or NATO procurement. Spring Sun First Tactical International operates from Wanchai, Hong Kong, a trading and logistics hub without indigenous ceramic manufacturing. Buyers must confirm whether production occurs in mainland China or elsewhere, the specific subcontractor or manufacturing partner, and whether NIJ certification testing was conducted at an accredited laboratory with witnessed test protocols.

Spring Sun First Tactical International Co., Ltd. maintains a registered address at 22/F., 3 Lockhart Road, Wanchai, Hong Kong, placing it in a commercial rather than industrial district of the Special Administrative Region. The company holds harbor trust tier status with no response rate data available, indicating limited platform engagement history. Hong Kong's role as a trade and logistics center suggests this entity likely functions as a trading company or brand holder rather than a primary manufacturer, though this is not explicitly confirmed in available data. The name implies focus on tactical and protective equipment markets.

No manufacturing facility address, production capacity, workforce size, or revenue figures are provided in source materials. The supplier's description emphasizes proprietary forming and sintering processes without disclosing whether these are conducted in-house or through contracted partners. Buyers should verify the actual manufacturing location, quality management certifications (ISO 9001, ISO 14001, or defense-specific AQAP 2110), and whether the company holds any direct NIJ certification or relies on component testing. Given Hong Kong's export control framework and the controlled nature of ballistic materials, confirm the supplier's compliance with Hong Kong Strategic Commodities Control and any applicable U.S. ITAR or EAR restrictions for re-export.
