Confidential RFQ workflow
How to Share Confidential Drawings with Suppliers
Reduce unnecessary disclosure by confirming authority, staging the technical package and controlling who can access, use and retain each revision.

Direct answer
How Should a Buyer Share a Confidential Drawing?
Share confidential drawings in stages, beginning with the minimum information needed for the current decision. First confirm authority to disclose and screen for customer, contractual, licensing and regulatory restrictions. Identify the recipient legal entity and permitted users, establish appropriate confidentiality and use terms before sensitive release, label and version every file, use controlled access, and keep a disclosure record. An NDA can clarify obligations, but it cannot prevent every leak or guarantee trade-secret protection.
- Confirm ownership, disclosure authority and applicable restrictions before transmission.
- Release the minimum package needed for the stated capability, quote, sample or production decision.
- Control recipients, permitted use, revision, access, closeout and incident records.
This is TW RFQ operational guidance, not legal or export-control advice. Taiwan law and WIPO sources support reasonable secrecy measures; NIST supports risk-based protection. BIS sources illustrate a U.S.-specific screening workflow only where the EAR applies; applicability depends on jurisdiction, item or technology, parties, destination and end use. None guarantees protection for a particular file.

Decision framework
Drawing-Disclosure Decision Record
The right control depends on information value, purpose, ownership, jurisdiction and recipient. Escalate unresolved legal or export questions before release.
| Control question | Required decision |
|---|---|
| Authority | Confirm ownership or written authority from the customer, employer, licensor or other rights holder. |
| Information class | Mark the package as public, internal, confidential, potential trade secret or separately regulated. |
| Regulatory status | Determine whether the item or technology is subject to applicable export-control rules and whether specialist review or authorization is required before release. |
| Current purpose | Define whether the recipient is assessing capability, quoting, sampling or producing approved goods. |
| Minimum package | Release only the geometry, requirements and supporting data necessary for that stated purpose. |
| Authorized recipients | Record the legal entity, users, sites and whether subcontractor or service-provider access is permitted. |
| Transfer channel | Select a channel from the information class and applicable policy; define recipient authentication, multi-factor authentication where required, download or print rights, expiry, access logging and closeout. |
| Contractual controls | Address confidential information, permitted use, exceptions, security, duration, return or destruction and incidents. |
| Technical lifecycle | Apply revision status, access expiry, logging, superseded-file withdrawal and project closeout. |

Confidential Drawing Transfer-Control Matrix
Classify the information before choosing a channel. Fill every control from the agreement and applicable policy; the examples below are prompts, not universal legal requirements.
| Information class | Minimum package | Authorized recipients | Authentication | Download/print | Expiry | Access log | Closeout |
|---|---|---|---|---|---|---|---|
| Capability screen | Envelope and non-sensitive requirements | Named evaluation contacts | Record approved method | State allowed or blocked | Set date or decision event | Name log owner and retention | Define withdraw or retain rule |
| Controlled quotation package | Quote-critical geometry and specifications | Approved quote team and sites | Confirm identity and MFA if required | State allowed or blocked | Set quote deadline or event | Name log owner and retention | Define revoke and supersede rule |
| Sample or production release | Approved revision and necessary manufacturing data | Approved production and downstream users | Record approved strong-authentication method | State allowed or blocked | Set project or revision event | Name log owner and retention | Define return, delete or retain rule |
Confirm the Right to Disclose Before Transmission
Identify who owns the drawing, model, specification and embedded third-party information. Customer-owned, licensed or jointly developed files may carry restrictions that the RFQ preparer cannot waive.
Determine whether the item or technology is subject to applicable export-control rules before cross-border release, and obtain specialist review or authorization when required. An NDA or encryption does not replace a required authorization.
TW RFQ submissions are private for human review and are not posted to a public marketplace. That does not authorize TW RFQ to receive restricted technical data; the sender remains responsible for disclosure authority and must identify restrictions before upload.

Release Information in Stages
Match disclosure to the current decision. An early capability screen may use a non-confidential description and approximate envelope; a quotation package needs the controlled data required for a reliable offer.
Minimum necessary disclosure does not mean an intentionally misleading specification. Mark withheld or unresolved requirements so nobody mistakes an assumption for approval.

Define Permitted Use and Recipients
Before sensitive disclosure, decide whether a confidentiality clause or separate NDA fits the purpose and jurisdictions. Obtain qualified legal review where needed.
Clarify confidential information, permitted purpose, recipients, subcontractors, exceptions, duration, incident notice, return or destruction and rights to manufacture or create derivatives.
- WIPO Guide to Trade Secrets and Innovation — Trade Secret Management — World Intellectual Property Organization
Control the Files and Access Path
Give each package a project identifier, drawing number, revision, release status, owner and marking. Redact unrelated know-how and use an approved transfer channel with access proportionate to risk.
State whether recipients may download, print, use external translation or CAD services, or upload files to generative-AI and other third-party systems.

Close the Disclosure Loop
When a quote, sample project or review ends, identify the latest authorized revision, revoke unnecessary access and withdraw obsolete packages.
Follow the agreed return, deletion or destruction process while accounting for legal retention and backups. Preserve disclosure, approval and incident records instead of destroying evidence.

Working checklist
Confidential Drawing Release Checklist
Record the answer, evidence source and unresolved owner instead of treating a blank field as confirmed.
- Ownership and authority to disclose every file are confirmed.
- Customer, license and applicable export-control restrictions are screened.
- Each file is classified and unrelated confidential information is removed.
- The purpose and minimum necessary package are documented.
- Recipient legal entity, users, locations and subcontractors are identified.
- Appropriate confidentiality and use terms precede sensitive release.
- Drawing number, revision, release status, owner and marking are visible.
- Access is authenticated, need-to-know, time-limited and logged proportionately.
- Rules for downloads, cloud tools, translation and generative AI are explicit.
- Revocation, superseded-file withdrawal, closeout and incident contacts are defined.
Avoidable risk
Controls That Look Strong but Leave a Gap
NDA as guarantee
Contract signing is treated as proof that leakage cannot occur.
Blanket package release
Complete CAD and process know-how are sent before the recipient needs them.
Uncontrolled downstream use
Subcontractors, cloud systems or AI tools receive data without explicit permission.
No closeout
Obsolete revisions and expired candidates retain access indefinitely.
Buyer questions
Frequently Asked Questions
These answers are preparation guidance, not a substitute for part-specific engineering or approval.
Is ordinary email appropriate for confidential CAD?
Not automatically. Choose a channel from the information classification, contract and applicable policy. Confirm the recipient, authentication, access duration, download rights, revision status and closeout process. Encryption does not create disclosure authority.
Do I always need an NDA before sharing a drawing?
Not every drawing or early discussion requires the same agreement. The answer depends on the information, purpose, existing contracts and applicable law. Sensitive pre-contract disclosure usually deserves specific legal and operational review.
Is a signed NDA enough to protect a trade secret?
No. WIPO describes practical secrecy measures alongside contractual controls. Limit disclosure, control access, mark files and maintain records appropriate to the information and risk.
What if the drawing may be customer-owned or export-controlled?
Do not upload or transmit it until disclosure authority is confirmed and any required specialist review or authorization is resolved. An NDA does not cure missing permission or authorization.
