A visit is not a trophy. It does not “approve” a supplier or guarantee performance. It is a way to test named questions, collect primary evidence, and reduce uncertainty. This guide focuses on what to record, not just what to look at—so you can turn a day on the factory floor into decision-ready notes.
Preparation: define the questions you will test
- Clarify the business goal driving the visit. Examples: confirm a machining process the supplier claims to have in‑house; verify they can hold ±0.05 mm on a critical feature; see how they control color consistency; understand their packaging and drop‑test routine.
- Write down the hypotheses you want to check. “Supplier machines housings on 4‑axis VMCs, 3 fixtures, 2 operators per line, 1,000 pcs/day” is testable. “Supplier seems professional” is not.
- Limit the scope. You will not see everything in one visit. Choose 3–5 must‑see steps that directly affect form, fit, function, and lead time.
- Request what you need in advance. Ask to see your product (or nearest equivalent) running; the process traveler or routing sheet; sample inspection records; packaging line; and any rework/repair area.
Use Incoterms correctly—but don’t confuse them with the whole deal
- Incoterms 2020 contain 11 rules that the International Chamber of Commerce (ICC) designed to clarify buyer and seller responsibilities and to allocate cost, risk, and obligations in delivery. They are useful for aligning who handles transport, export clearance, and risk at each handoff.
- However, Incoterms do not themselves settle price, payment timing, when ownership transfers, product conformity, delay liability, or how disputes are resolved. Those must be addressed elsewhere in your contract and commercial documents. These boundaries are emphasized by the U.S. International Trade Administration and the ICC.
- Before you visit, ensure your team knows which Incoterm you intend to use and what it means operationally for pickup points, packaging specs, and insurance—so your questions on the floor match the delivery plan.
Treat the visit as part of due diligence, not a substitute for it
- A structured visit is one element of broader due diligence. The U.S. International Trade Administration notes that due diligence helps protect a company from problems, loss, and liability and should continue as your business expands. Plan how the visit’s findings will trigger further checks (e.g., references, pilot orders, or capacity trials).
Plan your agenda and your consent boundaries
- Send a one‑page visit brief (see template below) so hosts know what you will ask to see.
- Align on photography: where photos are allowed, who approves them, and whether serials or customer names must be masked.
- Build in time for the specific line you care about, not just a walk through general areas.
- Bring what you need: safety shoes, ear protection, calipers or gauges if appropriate, a flashlight, notebook or tablet with offline checklist, translation support, and a device for timestamped photos.
Arrival: start with identity and context, not the machines Your first notes should establish where you are, who you met, and what was agreed.
Record
- Full physical address as shown at the gate and on any signage.
- Legal/company name(s) as displayed on the foyer plaque, business license board, or reception materials. Note if the factory name differs from the sales entity on your quotes.
- Names, roles, and contact details of your host(s): owner/GM, sales manager, production manager, quality lead, engineering contact.
- Date, time in/out, and any scope limitations or areas off‑limits stated at reception.
- Visible certifications or registrations displayed in the lobby (do not assume authenticity or scope from wall plaques; photograph only with permission for later verification).
Ask early
- What products are running today that are closest to your item?
- Which processes for your item are done here versus by subcontractors?
- What is the current stage of your parts: sampling, pilot, or mass production?
On the floor: what to observe and what to record As you walk, anchor each observation to a claim you are testing. For every area relevant to your product, capture these elements.
Product or sample stage
- Identify clearly: prototype, first article, pilot run, or mass production.
- If your exact item is not running, document the nearest comparable model/material running, and how it differs.
Production areas relevant to your item
- Map the intended process flow for your part (e.g., incoming aluminum billets → CNC roughing → heat treat (off‑site) → CNC finishing → deburr → anodize (off‑site) → final inspection → packaging).
- Note which stations are seen in-house and which are externally sourced. Photograph flow diagrams on whiteboards if permitted.
Equipment in relation to the claimed process
- Record make/model, count, and apparent condition of critical equipment (e.g., 4‑axis VMCs, injection presses tonnage, SMT lines). Note any fixtures, jigs, and measurement tools specific to your part.
- Ask how they program, control, and back up machine parameters. Record who is responsible for change control.
Incoming materials (when visible)
- Observe goods receiving: labeling, quarantine area, and how material certifications or COAs are handled.
- Capture how raw materials are identified (heat lots, resin batches), and whether your supplier can maintain lot segregation for your orders.
In‑process and final quality checkpoints
- Identify check stations at critical control points: what’s measured, on what frequency, using which gauges, and by whom.
- Request to see a filled‑out inspection sheet for the product family closest to yours; note date/time and operator initials (if any).
- Observe calibration stickers on gauges; record dates where visible, without drawing legal conclusions.
Packaging flow
- Follow a finished unit through cleaning, labeling, inner packaging, and carton sealing if possible.
- Note how dunnage is set, how cartons are tested or stacked, and whether export marks are applied consistently with your shipping plan.
Traceability or records (when available)
- Ask how they would trace a defect back to a batch, machine, or operator. Record the system (paper travelers, ERP entries) and retention period described.
- Photograph redacted examples of travelers, labels, or barcodes if allowed.
People and roles
- Observe operator‑to‑machine ratios, shift handovers, and training aids posted near machines.
- Record the presence of a quality lead at line side, not just in a lab.
Photos permitted
- Keep a list of what you photographed, where, and under what restrictions. Avoid capturing sensitive customer names or proprietary drawings unless expressly allowed.
Questions asked and answers given
- Write exact questions you asked and succinct answers, including who answered. Mark assumptions or points that need documents later.
Uncertainties that remain
- Note anything material that you could not see or that remained ambiguous (e.g., off‑site heat treat capability; actual first‑pass yield; subcontractor for anodizing).
What a short visit cannot prove A factory walk‑through is a snapshot. Be explicit about its limits:
- Capacity over time. You can see equipment today, not sustained throughput or on‑time performance across months.
- Real quality rates. You will not validate scrap, rework, or field failure rates without data from extended runs.
- Social and environmental compliance. Lobby certificates or brief tours are not proofs of compliance; specialized audits are separate activities.
- Authenticity of documentation. Certificates on walls and sample records require independent verification.
- Stability of the supply chain. Subcontracting, material sources, and staffing can change after your visit.
- Security of your IP. You cannot confirm how drawings are controlled or shared across the broader supplier network from one visit.
- Contractual reliability. A courteous tour does not predict how disagreements will be handled. As noted earlier, Incoterms do not address price, payment timing, transfer of ownership, conformity, delay liability, or disputes.
A carry‑in toolkit: fast checklist Bring
- PPE required by the factory (confirm in advance), closed‑toe safety shoes, ear protection.
- Calipers or reference gauges if you need to spot‑check a critical dimension with permission.
- Notebook or tablet with your visit brief and shot list; spare battery packs.
- Offline copies of your drawings/specs with any sensitive details redacted for on‑floor use.
- Translation support or a glossary of key process terms in Chinese.
On‑site record these minimums
- Address and legal/company identity shown at reception.
- Host names, roles, and contact details.
- Current product/sample stage relevant to your item.
- Each process step relevant to your part: equipment, people, controls.
- Incoming material ID and how lots are labeled (if visible).
- In‑process and final QC checkpoints; an example inspection record.
- Packaging steps and export marks.
- Any traceability mechanism demonstrated.
- Photo permissions granted and files captured.
- Uncertainties that remain and documents requested.
Template: the visit brief you send in advance Purpose
- Primary objective(s): list 2–3 testable questions tied to product, process, or lead time.
- Product focus: part numbers, materials, tolerances that matter.
Scope and agenda
- Must‑see areas: list in process order (e.g., molding → trimming → printing → packing).
- Documents requested: routing sheet for [product family], one filled inspection record, packaging spec, example traveler (redacted OK).
- Live observation requested: nearest running product to [your item].
People
- Your attendees: names, roles, mobile numbers.
- Supplier attendees requested: production manager, quality lead, process engineer.
Logistics and consent
- Visit date/time window, expected duration.
- Photo/video policy: what’s allowed, how images will be handled.
- PPE you will bring and any site rules to acknowledge.
- Confidentiality: you will avoid photographing other customers’ IP.
Risks & assumptions
- Known constraints (e.g., off‑site plating).
- Hypotheses to test (e.g., can hold ±0.1 mm on hole positions with current fixtures).
Template: a decision‑ready visit report Executive summary (one page)
- Supplier name(s) observed, location(s), date.
- Traffic‑light summary by key question (Green/Amber/Red) with one‑line rationale.
Findings by question
- Question 1: restate the hypothesis you tested.
- What you saw: equipment, process, controls.
- Evidence: photos #1–3, doc references.
- Risks/gaps: what you could not confirm, dependencies (e.g., subcontractors).
Process flow snapshot
- Simple text map of steps seen vs. off‑site, with notes on cycle time where stated.
Quality control snapshot
- Checkpoints identified, measurement tools, sample inspection record observed (date/code).
Packaging and logistics snapshot
- Packaging flow, labeling, export marks, carton/pallet approach relevant to your Incoterm.
People and roles
- Contacts met and their responsibilities; who owns change control.
Open items and requests
- Documents/data requested post‑visit; due dates and responsible person.
Commercial implications
- Any changes implied to price drivers (e.g., added process steps, new fixtures).
- Terms needing alignment outside Incoterms (e.g., payment timing, conformity criteria, penalties—handled in your contract, not by Incoterms).
Recommendations and next steps
- Go/No‑go for: engineering sample, pilot run, or alternate supplier search.
- Proposed validations: capability study on two critical dimensions; trial packaging and drop test; small pilot order with enhanced inspection.
Appendices
- Photo log (thumbnails with captions and permissions).
- Copies of non‑confidential records provided on site.
How to approach questions on capacity and lead time
- Ask for last month’s production volume for the closest product family, by line or machine group. Record the numbers as stated; do not assume they are validated.
- Note shift patterns and any planned additions or maintenance downtime.
- If capacity is critical, propose a limited pilot under observation or request a time‑stamped run chart from the past two weeks. Treat this as input to due diligence, not proof.
Handling photos and data responsibly
- Obtain explicit permission before photographing any station, label, or document; write down the boundaries.
- Use a consistent naming scheme: SupplierName_Area_Step_Num_Time.jpg to support later traceability.
- Avoid capturing customer names or drawings. If unavoidable, crop or redact before sharing internally.
- Store photos and notes in a shared folder the same day, with access limited to your project team.
How to engage constructively on subcontracted steps
- Ask which steps go off‑site, how parts are identified, and how they verify work on return.
- Record transport frequency, packaging used in transit, and what inspection happens at re‑receipt.
- If off‑site steps are critical to function or finish (e.g., heat treat, anodizing, plating), plan a focused visit there or define incoming acceptance tests at your supplier’s dock.
Converting observations into decisions A clear next step is more valuable than a thick photo album. Link your conclusions to specific actions:
- If the process exists and controls are visible but fixtures look improvised, request fixture qualification and a focused capability check on two features.
- If the right equipment exists but your product was not running, schedule a day‑certain trial on your material with your drawing, then attend or review a video walkthrough.
- If packaging looks adequate but you did not see transport tests, send your packaging spec and ask for a documented trial (photos, weights, stack heights).
- If key questions remain unresolved (e.g., traceability), pause on commitments that assume mature controls and expand due diligence.
Continue due diligence after the visit
- Use the visit to prioritize what to verify next: references, data samples, pilot orders, or financial health checks.
- Remember, per guidance from the U.S. International Trade Administration, due diligence helps protect your company from problems, loss, and liability and should continue as your business grows. A promising visit is the start of that cycle, not the end.
What the buyer should—and should not—say on site Do
- Share your drawing’s critical-to-quality features and why they matter.
- Explain your intended Incoterm so packaging and handoff points are clear operationally.
- Ask how changes are approved, documented, and communicated.
Avoid
- Promising volumes or prices on the spot.
- Treating Incoterms as a catch‑all for commercial terms. As noted, Incoterms 2020 allocate tasks, costs, and risk in delivery, but they do not decide price, payment timing, transfer of ownership, product conformity, delay liability, or dispute resolution. Handle those elsewhere in your agreement.
A concise walk‑route for most factory types
- Reception and document wall: identity and scope limits.
- Warehouse in: labeling, quarantine, lot control.
- Incoming QC: what, how often, and with what tools.
- Core process steps: for your part family, in order.
- Rework/repair area: what fails and how it’s handled.
- Lab/metrology: tools used for your critical features.
- Final QC and packing: inspection, labeling, sealing.
- Warehouse out: staging, palletizing, export marks.
When to ask for local support Local travel support or a sourcing partner can make a short visit more productive by arranging access to the right lines, clarifying technical terms in both languages, documenting observations (photos and notes) within agreed boundaries, and following up promptly on open items with production and quality teams. They can also revisit the site to confirm that agreed corrections were implemented and to observe a trial run when your team cannot be present. A sourcing partner does not certify compliance, provide legal verification, or “approve” a factory; their role is to help you plan the visit, ask targeted process questions, record what is observable, and keep the due‑diligence loop moving between visits.
