Dayang Trust Escrow System & B2B Trading Guidelines

1 Scope & Binding Legal Nature

These Platform Trading & Security Rules govern all commercial engagements, item listings, custom manufacturing requests, financial escrows, and disputes conducted on the 8btm.com (8btm.com) platform. By creating an account or placing an order, buyers and suppliers enter into a legally enforceable agreement with ZHILEI.

2 The Dayang Trust Escrow System

To eliminate the risk of international trade defaults, 8btm.com operates the proprietary Dayang Trust Escrow Architecture:

1. Payment Deposit

Buyer deposits payment via PayPal, international credit card, or SWIFT wire into 8btm.com's neutral escrow vault.

2. Certified Fabrication

The vendor executes manufacturing strictly against technical drawings and ships with full tracking within the agreed lead time.

3. Verified Release

Funds are released to the vendor only after verified arrival and the buyer's 7-day physical inspection window.

3 Listing & Fabrication Standards

Dimensional & Tolerance Accuracy: Unless custom tolerances are explicitly specified on engineering drawings, all CNC machined and 3D printed components must satisfy ISO 2768-m (Medium) precision standards.
Authentic Raw Material Documentation: Vendors must furnish genuine mill test certificates (MTC) verifying raw material alloy grades (e.g., AlSi10Mg, 316L, Ti-6Al-4V) upon request.
No Sub-Tier Outsourcing without Approval: Certified suppliers may not transfer sensitive manufacturing tasks to unverified third parties without written authorization from 8btm.com.
