PRECISION RUBBER PARTS: MANUFACTURING & GLOBAL SUPPLY

Solid Silicone (VMQ)

Specializing in High-Consistency Rubber (HCR). Platinum-Cured for medical-grade and Peroxide-Cured for high-temp stability.

EPDM (Ethylene Propylene Diene Monomer)

Superior ozone and UV resistance. Ideal for automotive sealing and outdoor industrial gaskets.

NBR (Nitrile Butadiene Rubber)

Optimized for industrial seals and O-rings requiring high oil and fuel resistance.

QA/QC & Global Supply

• Timeline: Ongoing / Final Dispatch

• Action: 100% final inspection and OQC (Outgoing Quality Control). Door-to-door delivery via DHL, FedEx, UPS. 

• Global Air Express (UPS Flat Fee): This is our standard fulfillment for both Standardized Series and Custom-Engineered Parts, ranging from R&D samples to Mass Production (1,000,000+ pieces). By leveraging micro-geometry, we provide a Volume-based Flat UPS Fee for rapid door-to-door delivery via Noi Bai International Airport (HAN), ensuring predictable costs and zero-latency supply chains.

• Sea Freight & Bulk Shipping: Engineered for high-volume, large-dimension industrial components requiring heavy-duty container shipping. We utilize Hai Phong Port (HPH), the largest deep-sea hub in Northern Vietnam, to provide cost-effective, reliable, and scalable maritime solutions for our partners across the USA, Canada, and the European Union, managing everything from port-to-port to final destination.

• Compliance & Duty Management: All shipments include a comprehensive documentation suite—including Invoice, Packing List, COA, and CO—to ensure seamless customs clearance. Under DAP terms, Vina Rubber manages 100% of the international transportation and export formalities, while local import duties and taxes remain the receiver's responsibility for full regulatory transparency.
