Background and Positioning

Haizol addresses the main risks in cross-border custom manufacturing sourcing: unclear factory capability, misinterpreted drawings, unrealistic pricing, and fragmented communication.

The platform operates a Request for Quotation (RFQ) workflow for non-standard OEM parts rather than open supplier listings or instant algorithmic pricing. Buyers submit Computer-Aided Design (CAD) files with material specifications, tolerances, quantities, and certification requirements, and RFQs are distributed only to verified factories with active membership. Multiple comparable quotations are returned within 24 hours.

Structured factory transparency is provided by attaching detailed factory profiles to each quotation. These profiles allow side-by-side comparison by location, capabilities, certifications, capacity, and equipment, enabling factories to be evaluated by technical fit rather than price alone.

Haizol integrates supplier verification, non-disclosure agreement (NDA) handling, centralized communication, and end-to-end project tracking into a single system covering quotation, production, and logistics. Each buyer is supported by a dedicated account manager who assists with RFQ refinement, factory capability evaluation, supplier shortlisting, factory coordination, and production issue resolution.

Haizol Platform: Frequently Asked Questions

What exactly does "verified factory" mean on Haizol?

A verified factory is a supplier that has passed Haizol's qualification process and is authorized to receive and respond to RFQs on the platform.

Verification includes review of business licenses and legal registration, confirmation of production and quality control equipment through facility checks, validation of industry certifications, and assessment of the factory's ability to manufacture the specified part types, volumes, and tolerances.

Only factories with active verified status can submit quotations through the marketplace.

How does the Haizol RFQ process work from submission to delivery?

Haizol's workflow is designed to be transparent and guided at every step:

  1. You submit an RFQ by uploading CAD files and specifying materials, tolerances, quantities, and required certifications.
  2. Haizol releases the RFQ to verified factories based on process capability, material compatibility, and available capacity.
  3. Multiple comparable quotations are typically returned within approximately 24 hours.
  4. Review supplier profiles side by side, including their equipment, quality control systems, certifications, and their pricing.
  5. Select and award the job to your chosen factory through the platform.
  6. Production progress and order status are tracked on the platform through completion and shipment.

Is Haizol a good fit for my project?

Haizol is a good fit for projects involving custom, drawing-based metal or plastic parts where technical reliability, supplier verification, and controlled sourcing matter.

Haizol is suited for projects that require:

  • Non-standard OEM parts requiring specifications and tooling.
  • Verified factories with clear capability documentation.
  • The ability to compare multiple suppliers transparently.
  • Guided support managing RFQs from inquiry through production.
  • Cost-competitive sourcing without sacrificing quality control.

The platform supports prototype quantities through full production volumes across aerospace, automotive, medical devices, robotics, consumer electronics, and industrial equipment.

What should I prepare before asking Haizol for quotes?

To receive accurate, useful quotations, prepare:

Essential information:

  • Drawings or CAD files (STEP, IGES, DWG, PDF)
  • Material specifications
  • Critical tolerances and surface finishes
  • Expected quantities (prototype batch + anticipated production volume)
  • Required certifications (ISO 13485, AS9100, IATF 16949, etc.)
  • Target delivery region

Helpful additional details:

  • Level of NDA agreement
  • Material grade
  • Timeline expectations and any rush requirements

The more clarity you provide up front, the more realistic and comparable your quotes will be.

How does Haizol help avoid misread drawings and "wrong part" situations?

Haizol reduces the risk of drawing misinterpretation and incorrect parts through capability-based factory matching, pre-quote clarification, and RFQ review before production begins.

  • Capability-based factory matching: Your RFQ is matched to factories with experience in your material, process, and tolerance requirements, not random suppliers.
  • Engineering team: RFQs will be reviewed for manufacturability and specification completeness before release to factories.
  • Centralized communication and version control: All messages, drawings, and file revisions are managed within the platform to maintain a single traceable record.
  • Factory AI-supported tools: Haizol provides AI-assisted quotation tools that generate structured quotes using factory-specific machines, material libraries, and process data. AI-assisted translation tools help factories accurately interpret drawings and technical specifications before order award.
  • Account manager review: Dedicated account managers identify unclear specifications, flag potential misunderstandings, and facilitate clarification before production.

How does IP protection and NDA handling work on Haizol?

Haizol provides three configurable NDA options to control access to engineering files during the RFQ process.

Three levels of NDA on Haizol:

  1. No NDA Required, allowing suppliers to download files without signing an NDA.
  2. Level-1 NDA requires all suppliers to digitally sign Haizol's standard legally binding NDA before accessing drawings.
  3. Level-2 NDA allows buyers to upload their own NDA, which suppliers must manually sign and upload for approval before file access is granted.

How should I choose between multiple suppliers on Haizol?

On Haizol, many buyers prioritize supplier credibility over the lowest unit price. Unusually low quotations are commonly treated as a risk signal, as they may indicate misinterpreted drawings or incomplete cost assumptions.

When comparing factory profiles, many buyers prefer to evaluate additional factors:

  • Material experience: Have they worked with similar material before?
  • Equipment match: Do their listed machines handle their tolerances and complexity?
  • Certifications: Do they hold the industry standards the project requires?
  • Communication quality: Did they ask intelligent questions or just quote blindly?
  • Lead time realism: Does their timeline match their schedule?
  • Past work: Do their capability product portfolio photos show similar parts?

Haizol's side-by-side factory profiles make these comparisons transparent, so you can choose with confidence rather than guessing.

What practical steps can I take on Haizol to reduce quality risk?

The safest path is always to handle the complete project within Haizol's platform. That way, all communication between you and the factory is traceable. In the event of any dispute, Haizol's account managers may be able to help coordinate inquiries with the factories.

What if a supplier changes price, delays, or backs out after quoting?

Haizol's model is designed to catch capability and commitment issues during the quoting phase, so post-award surprises happen less often than with unfiltered marketplaces.

If a supplier becomes unreliable after award, you have several advantages:

  • Account manager intervention: Your dedicated manager monitors your project and can push the factory for resolution or negotiate adjustments before issues escalate.
  • Communication history: All quotes, messages, and agreements are documented in your Haizol workspace, giving you clear evidence for disputes or negotiations.
  • Alternative suppliers: Because you received multiple quotes initially, you can quickly pivot to another verified factory from your shortlist without starting the RFQ process from zero.

How does Haizol earn its revenue?

Haizol earns revenue from verified factories through paid platform membership, not from buyer fees. Buyers receive factory-direct pricing and do not pay for RFQ submission, quote comparison, or account manager support, which avoids conflicts of interest in supplier recommendations.

How is Haizol different from Haizol Global?

  • Haizol: A factory‑direct RFQ marketplace for custom parts where buyers get quotes and work directly with verified Chinese factories via the platform.
  • Haizol Global: An independent one‑stop sourcing and project management company that uses qualified supplier networks and in‑house engineering to deliver end‑to‑end manufacturing as a managed service.

Are there minimum order quantities when sourcing through Haizol?

There is no minimum order quantity requirement for submitting RFQs on Haizol. Factories independently decide whether to quote based on part complexity, process requirements, and order volume. Higher quantities receive more quotations and competitive pricing, while lower quantities may result in fewer supplier responses.

How many quotations will I receive from factories when submitting an RFQ on Haizol?

90% of RFQs released on Haizol's platform receive quotes from 8 or more different verified factories.
