Services

Six things I do, done carefully

Each service stands alone; together they form a full sourcing cycle.

Supplier Sourcing & Vetting

Real manufacturers only — licenses, capacity and export history checked before they reach your shortlist.

Factory Audits

On-site or live video: lines, QC stations, certificates. You see what I see — photos and footage included.

Quoting & Negotiation

Line-by-line BOM and kitting quotes — unit price, tooling, packaging and lead time, side by side.

QC & Pre-shipment Inspection

AQL-based final inspection before anything ships. Defects are caught at the factory, not in your warehouse.

Production Follow-up

Milestone tracking with dated photo updates — a 40-day lead time never becomes 40 days of silence.

Consolidation & Shipping

Multi-supplier consolidation into one shipment, export paperwork, forwarder coordination.

Evidence, Not Promises

The audit trail behind every order

Trust in sourcing shouldn't rest on a nice website. Every project I run leaves a documented trail you can file, share with your team, and refer back to in any dispute.

Step 1

Verification File

Business license, export records and capacity check for every factory on your shortlist.​

Step 2

Audit Report

Timestamped photo & video from the production line, warehouse and QC stations.​

Step 3

Quote Comparison

Line-by-line cost breakdown per factory — the honest floor price, in writing.

Step 4

Inspection Record

AQL sampling data, defect photos and pass/fail verdict before balance payment.

Why Me

Three commitments, in writing

About

Hannah Han

Hannah Han, independent sourcing & QC agent in Shenzhen

I run Nan Bridge QC & Sourcing as an independent purchasing agent for small and mid-sized importers, brand owners and e-commerce sellers.​

Most sourcing failures are not sourcing failures — they are verification failures. A "certified" supplier that is a trading office; a first order that ships fine, a second that quietly downgrades materials. My work closes that gap with documentation, not assurances.

FAQ

Buyers usually ask

How do you charge?

Per service, at rates published in writing before work starts — the quote does not change afterwards.​

Do you take commission from factories?

No. My income comes only from client fees — which is exactly why a cost-effective factory is the recommendation I make.​

Can I pay the factory directly?

Yes, and I encourage it. Contracts and payments go directly between you and the manufacturer; I handle verification, audits and inspection.

Do you work with small orders?

Yes — consolidation and kitting exist to make small and mid-size orders viable. Send your target volume for a detailed answer.​
