30,000 Verified Chinese Manufacturers’ Business Leads – High-Quality B2B Contact Database

Project Description

I am looking for an experienced lead generation specialist or B2B data researcher to compile a database of **30,000 verified and valid business leads from manufacturers based in China**.

The project requires high-quality, accurate, and usable business contact information for legitimate Chinese manufacturing companies. This is strictly a B2B lead generation project. The primary objective is to obtain direct business contacts from relevant departments within manufacturing companies, rather than generic corporate email addresses or low-quality bulk data.

## 1. Lead Requirements

- **Total required leads:** 30,000.
- **Target country:** China only.
- **Target companies:** Genuine, active manufacturing companies based in China.
- **Lead type:** Strictly business-to-business (B2B) contacts.
- **Uniqueness:** Only one lead per company domain. Multiple contacts from the same company or domain will not be accepted.
- **Email quality:** All email addresses must be verified, valid, and associated with the respective company and business contact.
- **Data accuracy:** Company names, domains, email addresses, and other contact details must be consistent and accurate.
- **No duplicate records:** The final database must be deduplicated by company domain, email address, and company name.

Each record must represent a unique manufacturing company, with no more than one lead sourced from the same company domain.

## 2. Preferred Email Addresses and Job Functions

I am specifically interested in business email addresses associated with relevant operational, commercial, financial, and logistics departments.

Preferred email addresses should relate to roles such as:

- Sales and Sales Management
- International Sales and Export Sales
- Import and Export Departments
- Accounts and Finance
- Purchasing and Procurement
- Business Development
- General Manager and Operations Manager
- Supply Chain Management
- Shipping and Logistics
- Export and Freight Management
- Production and Factory Management
- Procurement and Sourcing
- Commercial and Trade Management

Email addresses must belong to real, relevant companies and must pass the agreed verification criteria. Named business contacts with verified professional email addresses are also acceptable where available.

## 3. Strictly Prohibited Email Addresses

**Do not include generic or non-target departmental inboxes** such as:

- contact@
- info@
- inquiry@ / enquiries@
- support@
- security@
- admin@
- webmaster@
- help@
- service@
- noreply@ / no-reply@
- feedback@
- careers@ / jobs@
- hr@

Similar general-purpose, automated, customer-support, or non-business-development addresses must also be excluded.

The objective is to obtain contacts relevant to actual commercial transactions, procurement, sales, international trade, accounting, management, and logistics.

## 4. Verification Requirements

Every email address must undergo verification before submission.

The verification process should include:

1. Checking that the email address is correctly formatted.
2. Verifying the email domain and its association with the listed company.
3. Using a reputable email verification tool to check deliverability.
4. Removing invalid, undeliverable, duplicate, and high-risk addresses.
5. Checking that the company is a genuine manufacturer, not merely a trading company, reseller, directory listing, or unrelated service provider.
6. Confirming that each company has a unique domain and appears to be an active business.

Please distinguish between verified deliverability and guaranteed inbox delivery. I expect the best achievable verification quality, with verification results and methodology disclosed.

## 5. Required Data Fields

Please deliver the leads in an organized Excel spreadsheet or CSV file containing the following fields wherever available:

1. Company Website
2. Company Domain
3. Verified Business Email Address
4. Job Title or Department
5. Manufacturer/Product Category
6. Email Verification Status

The spreadsheet must be clean, professionally structured, easy to filter, and ready for immediate B2B business use.

## 6. Quality Control and Acceptance Criteria

The following conditions are mandatory:

- Exactly 30,000 unique company leads, subject to the agreed delivery arrangement.
- One lead maximum per company domain.
- Chinese manufacturers only.
- No duplicate companies or email addresses.
- No prohibited generic inboxes.
- No fabricated company names, websites, or email addresses.
- No randomly generated or guessed email addresses presented as verified.
- No purchased, recycled, or scraped lists of unknown quality without proper validation.
- Every record must include a traceable company website or source URL.
- Invalid, unverifiable, or non-compliant records must be replaced.

Please disclose any limitations concerning catch-all domains, SMTP verification restrictions, or addresses whose deliverability cannot be conclusively established.

## 7. Delivery and Proposal Requirements

In your proposal, please explain:

1. Your experience in B2B lead generation, particularly with Chinese manufacturers.
2. The tools and methods you will use to identify and verify the companies and email addresses.
3. Your approach to ensuring one unique lead per company domain.
4. How you will distinguish genuine manufacturers from trading companies and resellers.
5. Your expected delivery timeline for all 30
,000 leads.
6. Your price for the complete project.
7. Whether you can provide a sample of 100–200 leads for quality assessment before proceeding with the full order.
8. Your replacement policy for duplicate, invalid, or non-compliant leads.

A small sample should be provided for review before full delivery so that the data structure, lead quality, email verification, and compliance with the requirements can be assessed.

## Final Note

I am prioritizing **accuracy, uniqueness, relevance, and verified business contact quality over simply reaching a large number of records**. I do not want a generic bulk email list. I need a properly researched, deduplicated, and verified database of Chinese manufacturing companies with business email addresses relevant to sales, imports, exports, accounts, procurement, management, shipping, and logistics.

Please submit a proposal only if you can meet these requirements and explain your verification process clearly.
