Send your drawings, specifications, quantities, and delivery requirements for a practical manufacturing review. Guanjie Technology supports international buyers who need practical engineering communication, coordinated manufacturing, and a clear route from RFQ to repeat production.
A Clear, Accountable Manufacturing Process
International custom manufacturing works best when technical, commercial, quality, and logistics information is managed as one project. Guanjie Technology aims to give buyers a clear route from initial inquiry to reviewed requirements, production planning, verification, and delivery.
For customers in the USA, Europe, Australia, and the Middle East, documentation and communication are especially important. Differences in terminology, standards, time zones, and shipping conditions can create risk if assumptions remain unrecorded. Guanjie encourages buyers to provide complete files and identify any requirement that is mandatory, negotiable, or still open.
RFQ Information Checklist
Contact and Company Details
Provide your name, company, business email, telephone or WhatsApp number, and country. Accurate contact details help route technical and commercial questions to the appropriate person.
Project Files
Upload the latest 2D drawings, 3D models, specifications, and reference images. Mark the controlling revision. If files are confidential or too large for the form, use the inquiry to request an appropriate transfer method and discuss confidentiality needs.
Commercial Requirements
State prototype quantity, order quantity, estimated annual demand, target date, delivery destination, and any required commercial terms. A target price may be useful context, but it does not replace a complete technical scope.
Technical Requirements
Confirm material, finish, tolerances, critical dimensions, assembly responsibilities, inspection documents, packaging, and labeling. If Guanjie is expected to recommend an option, clearly identify the open decision.
What Happens After Submission
The inquiry is reviewed for completeness and manufacturing relevance. The team may request clarification before quotation, especially where drawings conflict, specifications are missing, or quality expectations are not measurable. Once the scope is sufficiently clear, the next response may include technical questions, manufacturing assumptions, commercial information, or a recommendation for further review.
Submitting an RFQ is not an automatic production authorization. Final requirements, pricing, schedule, payment terms, shipping responsibilities, and order acceptance must be confirmed separately.
Protecting Project Clarity
Before submitting, remove obsolete drawings from the package and give each active file a recognizable revision. If multiple parts belong to one assembly, include a bill of materials or a simple relationship list. Identify whether quoted quantities apply to individual parts, complete sets, or annual forecasts.
Do not place essential requirements only in a file name or an image annotation that may be overlooked. Put controlling requirements in the drawing, specification, or RFQ notes. If the project is still at concept stage, say so directly. Guanjie can then treat the inquiry as an engineering discussion rather than assuming the files are ready for production.
Project Communication
Questions and decisions should reference the drawing revision or specification they affect. Verbal comments and isolated email statements can be useful for discussion, but final production requirements should be consolidated into controlled documents or an agreed written record.
When multiple stakeholders are involved, identify who can approve design changes, samples, quality documents, and commercial terms. This prevents well-intended feedback from becoming an unauthorized change.
Quality and Documentation
Quality is based on agreed requirements, not assumptions. Drawings should identify critical dimensions, materials, finishes, threads, weld details, appearance zones, and functional interfaces. If dimensional reports, material documents, coating records, photographs, or other evidence are required, include them in the RFQ.
The appropriate inspection approach depends on product risk, process stability, quantity, and customer requirements. Not every project needs the same reporting package. Defining the required evidence early helps avoid cost and schedule surprises.
International Delivery Preparation
Delivery planning includes part protection, package size and weight, labeling, export documents, transport mode, destination, and agreed responsibilities. Packaging must account for sharp edges, heavy components, moisture exposure, cosmetic surfaces, and movement during transport.
Buyers should confirm the receiving location and any unloading limitations. Country-specific compliance, import, certification, or marking requirements remain the buyer's responsibility to disclose and must be reviewed before order placement.

Frequently Asked Questions
What information should I include with my inquiry?
Send the latest drawing or 3D model, material and finish requirements, expected quantities, target delivery timing, application notes, inspection requirements, and the destination country. If some information is not yet fixed, identify it as open for engineering recommendation.
Can Guanjie review a project before formal production?
Yes. The review can identify missing dimensions, unclear specifications, process conflicts, and questions that affect quotation or production planning. Final feasibility remains subject to the complete files and confirmed requirements.
Do you support international projects?
Guanjie is positioned to support customers in the USA, Europe, Australia, and the Middle East. Project communication should confirm technical requirements, commercial terms, documentation, packaging, and shipping responsibilities before an order is released.
Can you support prototypes and repeat production?
Project suitability depends on the process, tooling, material, and quantity. Share both the immediate requirement and expected future demand so the manufacturing route can consider validation needs as well as repeat-order efficiency.
How are quality requirements confirmed?
Quality requirements should be documented in the drawing, specification, purchase order, or agreed inspection plan. Critical features, sampling expectations, reports, and any special documentation must be confirmed before production.
How do I request a quotation?
Use the Contact / RFQ page and upload the available files. A complete RFQ helps the team review manufacturability, clarify assumptions, and prepare an appropriate commercial response.
Send Your RFQ
Send Guanjie Technology your drawings, specifications, expected quantity, and delivery destination. The team will review the available information, identify questions that affect manufacturing, and help define the next practical step.
