Engineered to support heavy industry, biomedical cleanrooms, and plastic manufacturing facilities operating in San Pedro de Macorís. Built to OEM/ODM drawings with direct access to high-purity crystalline quartz deposits in Donghai, China.
San Pedro de Macorís represents one of the Caribbean’s most dynamic manufacturing landscapes, anchored by the Free Trade Zone (Zona Franca Industrial), major thermoelectric power stations, biomedical facilities, and heavy maritime processing.
Operating within the San Pedro de Macorís Free Zone, precision manufacturers utilize optically flat fused silica quartz plates (JGS1/JGS2) for UV bonding windows, laser cutting apertures, and bio-diagnostic testing fixtures where trace chemical neutrality is non-negotiable.
San Pedro’s energy cogeneration facilities and heavy industrial boiler systems require transparent quartz sight glass discs capable of withstanding working temperatures up to 1100°C without devitrification under intense cyclic steam pressure.
Dominican beverage producers and blow-molding plants integrate custom thermal quartz partition plates and infrared radiators inside preform heating tunnels to avoid hot spots, preventing bottle deformation during high-speed production runs.
Direct from Lianyungang, China, our fused silica plates maintain greater than 99.99% SiO2 purity, delivering extreme thermal shock resistance and near-zero coefficient of thermal expansion.

Kavri Quartz provides factory-direct export operations that streamline customs clearance, eliminate middleman markups, and protect mission-critical production timelines.
Quartz plates shipped to Puerto San Pedro or Caucedo undergo rigorous export packaging protocols: individually sealed in dust-proof EVA protective sleeves, backed with dual-layer PE wrap, and encased in reinforced ISPM-15 treated fumigated wooden crates.
We supply comprehensive technical documentation required by the Dominican National Export Free Zones Council (CNZFE) and DGA customs authorities, including Certificates of Origin (CO), RoHS certificates, physical test reports, and commercial pro-formas tailored for tax exemptions under Law 8-90.
Situated directly adjacent to Donghai County—China's silicone capital—our manufacturing hub holds continuous supplies of raw crystalline quartz, shielding Dominican buyers from global market price fluctuations and raw material shortages.
Direct answers addressing customs procedures, lead times, optical certifications, and customization parameters for Dominican engineers and plant managers.
Yes. We specialize in custom CNC machining, water-jet slicing, chamfering, laser drilling, and optical polishing. Simply provide DXF, DWG, PDF drawings, or physical dimensions (thickness, width, outer diameter, edge chamfers), and our engineering team will produce samples within 7 working days.
For express samples and urgent line-down replacement parts, air freight to Las Américas International Airport (SDQ) takes 5 to 8 business days. For volume container shipments destined for Port San Pedro de Macorís or DP World Caucedo, typical maritime transit ranges from 28 to 35 calendar days.
Fused quartz (SiO2 > 99.99%) is chemically inert to almost all acids (except hydrofluoric and hot phosphoric acid) and possesses total resistance to salt air corrosion, making it far superior to borosilicate or tempered soda-lime glass in San Pedro's coastal industrial settings.
For standard-dimension quartz plates, discs, and heating lamps, our MOQ begins at just 5 to 10 pieces to support plant maintenance teams. Custom sizes and tailored CNC machining requirements are quoted flexibly following drawing review.
Every optical plate undergoes strict bubble-class verification, spectroscopic transmission testing across UV-Vis-NIR bands, and optical surface interferometry ensuring a scratch-dig rating matching industrial specifications (such as 60/40 or 40/20) with inspection certificates included.
We regularly execute shipments under FOB, CIF (Caucedo/Rio Haina), CFR, EXW, and DDP terms. We routinely coordinate with designated Dominican freight forwarders to ensure clean import processing without dock demurrage.
