Top Questions from OKmarts Buyers
Q: What quality certificates or compliance documentation can be provided with the shipment?
A: Upon request, we provide standard manufacturer compliance documentation, including Certificates of Conformance (CoC), factory inspection reports, and CE/RoHS certification data sheets to ensure alignment with international regulatory and safety standards.
Q: Can OKmarts issue formalized, compliant proforma invoices and commercial invoices tailored for corporate accounting?
A: Absolutely. Our automated billing system generates itemized Proforma Invoices (PI) and Commercial Invoices containing corporate tax IDs, purchase order (PO) numbers, and explicit company details necessary to satisfy international corporate accounting and auditing standards.
Q: Can I request a live video inspection of my specific order items before they leave the OKmarts facility?
A: Yes. To maximize peace of mind for high-value or critical orders, buyers can request a "Pre-Shipment Video Verification." Our warehouse team will film the unboxing, display the original manufacturer seals, show matching serial numbers, and verify the physical condition of the components in real-time or via a high-definition video link.
