Alibaba.com B2B Sample Policy: Fees, Spec Freeze, and Stop-Loss (2026)

Key takeaway:

A sample policy is not a polite chat discount. It is a written fee schedule, a spec-freeze field set, and stop-loss triggers that must exist before any parcel leaves the warehouse. Shipping without a frozen version almost always creates disputes and sunk cost.
Free samples belong only in a narrow band: verifiable buyer intent plus low variable cost. Custom work, tooling, high-value materials, and repeated spec drift are paid by default, with deposit and/or deductible-against-first-bulk options.
Sample clauses must connect cleanly to later Trade Assurance bulk: version IDs, acceptance criteria, deviation handling, and payment path—so “sample one way, bulk another” does not appear in disputes.
When a buyer only samples, keeps rewriting artwork, or refuses sign-off, close in writing on stop-loss lines. For overall inquiry conversion cadence see inquiries-but-no-orders stop-loss; for first TA bulk rhythm see first Trade Assurance bulk order.

Many factories already receive Alibaba.com inquiries yet bleed cash in sampling: sales waives fees to “look helpful,” specs still change in chat on version three, and the parcel is already on a truck. The buyer says it “does not match the picture,” finance cannot reconcile courier and bench time, and the team keeps waiting for “sample feedback.” The failure is rarely the sample itself; it is the absence of a policy that sales, warehouse, and finance execute the same way.

This guide gives fee tiers, how to write cost lines, a pre-ship freeze checklist, deposit versus deductible rules, the handoff into Trade Assurance bulk, and stop-loss when buyers only sample. For air-versus-ocean channel choice on samples versus bulk, use ocean vs air for samples and bulk. Platform rules follow the Alibaba.com rule center and in-product prompts. Corpable explains paths; we do not collect goods payments or freight, and we do not promise inquiry volume or win rates.

Writing a one-page PDF is not enough. The same rules must gate warehouse release, map to finance ledger lines, and show up in sales KPIs. Only when those three surfaces move together do the sunk-cost paths close.

1. Samples burn cash first: three common sunk-cost paths

Sampling losses rarely look like “one courier invoice.” They compound from unlocked specs, verbal price changes, and unlimited revision rounds. Name the paths before you decide which doors the policy must shut.

For bulk lead-time wording see Lead-time promises (2026); for an executable follow-up Skill see K09 sample follow-up.

1.1 Path A: ship before the spec is frozen

The buyer changes color, connector, silk-screen, and packaging language across chat threads. Sales replies “OK, roughly the same.” After the parcel is in transit or delivered, the buyer claims mismatch and demands a reship. The fix is operational: any release requires a signed or time-stamped spec confirmation with a version ID. No version, no warehouse release.

1.2 Path B: one free sample becomes a standing obligation

A single free unit is screenshotted as “your company policy.” Every new SKU and every new contact then demands free samples, and sales fears saying no. The written policy must state free-sample triggers, quantity caps, and expiry conditions—not leave Discretion to whoever is online that night.

1.3 Path C: sample acceptance diverges from bulk acceptance

The sample is a polished hand sample; bulk ships to production tolerances. The buyer then uses sample photos inside a Trade Assurance argument. At sample time, state whether the unit is a design-confirmation piece, a production-representative piece, or a display hand sample, and what deviation range and inspection method will apply to bulk.

1.4 Indicative cost stack of one “free favor”

The table is structural, not a market quote. Backfill with your real bench hours and courier bills, then set free thresholds.

Line (illustrative)	Often missed	What the policy should say
Bench / rework hours	Materials only, no overtime	Include/exclude rework; revision surcharges
Courier and declared value	Rep hard to reimburse	Buyer prepaid or collect by default
Tooling / fixture share	“Make first, settle later”	Tooling as its own line; deductible rules explicit
Opportunity cost	A-tier rush quotes delayed	Sample slot rules on the weekly board

After the table: finance and sales pull the last 90 days of sample shipments, flag rows with unrecovered fees and no order, and treat those rows as the first holes the policy plugs.

1.5 Why “shipping a lot” can fake “strong conversion”

Rising sample counts on a weekly report look like activity. What matters is freeze confirmation rate, fee recovery rate, sample-to-bulk conversion, and how many A-tier quotes slipped because sampling consumed capacity. If the first three fall while the fourth rises, samples are crowding out closes. Run meetings on those four fields, not on “how many sets this week.”

Another disguise is “the buyer is still evaluating.” Evaluation is fine when it has a calendar date and a feedback format: tick the freeze form, file written deviations, or name the next decision-maker. “Still evaluating” with no format should be logged as no feedback, not as high intent.

2. Free versus paid: tier by category, stage, and buyer evidence

“Always charge” and “always free” are both too blunt. Executable tiers look at three things: sample variable cost, verifiable buyer intent, and the time budget you assign that lead.

2.1 Default paid

Custom dimensions, private-label print, special certification marks, new or modified tooling;
High unit cost, fragile goods, shelf-life or controlled categories;
Buyer refuses company identity, end market, or quantity band;
Same buyer entity already sampled within 90 days with no real progress (no freeze, no quote closure, no payment intent).

2.2 Narrow band where free (or freight-collect) can be considered

Standard stock SKU, low variable cost, can pull from inventory;
Buyer provided verifiable company data, target market, and first-order quantity band;
Written freeze on a version, plus acceptance of sample terms;
Sales tier is A (actionable rush) and the monthly free quota is not exhausted.

2.3 Minimum buyer evidence before you sample

Free shipping into a void is buying a “maybe” with cash. Collect at least: company name and site/registry clue, destination market, estimated first quantity, critical specs or drawings, consignee and customs entity. If more than two items are missing, fill information before any fee waiver.

2.4 Tier matrix (illustrative)

Lead profile (illustrative)	Fee stance	Stop-loss trigger
Standard part + verifiable entity + quantity band	Sample fee may be waived; freight buyer-paid	No freeze acknowledgement within N days after delivery
Light customization, no tooling	Sample fee + freight; may deduct on first bulk	Two rounds of price-only shopping without freeze
Tooling / high-value materials	Tooling + sample fee + deposit	Demands sample while refusing deposit
Repeat sample asks in 90 days, no progress	Full prepay, non-deductible	Downgrade immediately and close in writing

Read the matrix this way: fees serve stop-loss, not performative friendliness. Friendliness shows up as fast, professional freeze work—not unlimited free parcels.

2.5 Quotas beat one-off exceptions

Give the sales team a monthly or quarterly free-sample quota (by sets or by cost cap). When it is used up, switch to full prepay. Exceptions need a written reason, an approver, and a deductible yes/no. Quotas move the argument into the system instead of nightly bargaining, and they help finance forecast sample cash outflow.

New stores can use a “first 30-day observation quota”: slightly wider free allowance, but freeze forms and prepaid freight stay non-negotiable. After the window, rewrite next quarter’s quota from sample-to-bulk rates so you do not live forever in “launch exceptions.”

2.6 Multi-address and multi-contact sample farming

Different people or ports under one company asking again and again is a common pattern for competitor testing or serial sampling. Count quota by buyer entity over 90 days; a second address needs a stated purpose and prepay. Refusal to state purpose moves the lead to paid tier—out of the free pool.

3. How to write sample fees: unit price, freight, tooling, deposit vs deductible

Buyers, sales, and finance must read the same line items. If chat answers “is freight included?” differently every time, later Trade Assurance and reconciliation arguments are already seeded.

3.1 Lines worth separating

Sample unit price: by SKU or by standard vs reworked tiers; state tax posture and currency.
Freight and declared value: buyer prepaid or collect by default; if you advance freight, write a cap and reimbursement path.
Tooling / fixtures: separate line; state ownership (buyer-owned vs seller-retained) and custody.
Rush fee: surcharge when lead time is compressed—avoid verbal “we will jump the queue.”
Revision fee: how each change after freeze is priced.

3.2 Deposit versus deductible: do not merge the words

A deposit is risk cover: if the buyer walks, refuses freeze sign-off, or uses the sample for competitive teardown under agreed terms, you may retain part or all per the clause. A deductible is a commercial incentive: within a stated window, when the first bulk order lands via Trade Assurance or another agreed path, sample fees credit against goods value. Triggers, validity, and non-refund cases must be written separately. “We will see later” is not a clause.

3.3 Minimum fields for a deductible clause

Credit percentage or amount cap;
Same buyer entity and same spec version;
Validity window (illustrative: 30/60 days after sample delivery—set by category);
Payment path (for example, must be a Trade Assurance order);
Partial credit and non-credit cases (price-only fishing, resale to third parties, and similar).

3.4 Collection and evidence

Sample goods and freight should move through corporate or platform-accepted paths, with invoice/receipt plus chat confirmation retained. Platform membership fees are a different subject and must go to Alibaba’s official Hong Kong collecting entity when due; sample goods payments are trade receipts on your side. Do not blend courier reimbursements and membership fees into one opaque “going-global cost” bucket.

4. Spec freeze before ship: fields that must be written

Spec freeze is the spine of sample policy. Without a freeze form, elegant fee language will not stop “this is not what I asked for.”

4.1 Minimum freeze fields

SKU / model, spec version ID, and date;
Critical dimensions, materials, voltage/connectors, color and finish;
Print/label language and position; packaging language and marks;
Sample type: hand sample / production-representative / swatch kit, etc.;
Acceptance: visual, dimensional tolerances, functional tests;
Quantity, lead-time window, consignee and customs data;
Fee confirmation: sample fee, freight, deposit, deductible rules;
Confirmer names and timestamps (on-platform message or email is fine if auditable).

4.2 Warehouse release gate

“The buyer is urgent” is not a substitute for a freeze form. Release when the system shows a confirmed version ID, fee status (collected or agreed collect), and complete ship-to data. Missing any item sends the ticket back to sales.

4.3 Handling revisions

Any critical field change after freeze is a new version: bump the ID, re-price and re-date lead time, re-confirm, then produce or reship. Never “tweak a little” under the old version number.

4.4 Scene: two inquiries the same day

Buyer A sends drawings and a quantity band, confirms the freeze, and prepays freight. Buyer B only writes “send sample cheapest” and refuses company data. Under policy, A enters the bench queue; B receives a public spec PDF plus a paid-sample quote and never enters the free quota. A week later A moves toward Trade Assurance intent and B vanishes—that is the policy working, not “hurting customers.”

4.5 Priority among drawings, swatches, and physical samples

When PDF drawings, color swatches, and physical units coexist, the freeze form must say which wins on conflict. A common pattern: dimensions follow the dimensioned drawing; color follows the approved swatch batch ID; function follows the signed test list. Without priority, each side will pick the artifact that helps them in a dispute.

Electronic confirmation counts: on-platform messages, email, or a versioned PDF return all work when timestamps and version IDs are complete. A phone “we agreed” is not enough for warehouse release—follow with a short confirmation email that captures the oral conclusion in writing.

4.6 Third-party lab samples and retain samples

If the buyer wants a third-party lab, state who pays, how failed retests work, and how long the factory keeps retain samples. Retain units should match the shipped batch and version, with photos on file. On certification language, state only the true status—“already held” versus “can assist application”—and never write “we have the certificate” when you only mean you can start a project.

5. How samples connect to later Trade Assurance bulk

The end of sampling is not a polite delivery. It is whether you can enter an executable bulk contract and Trade Assurance order without rewriting the story. When the handoff fails, every fee and freeze gets re-litigated inside the dispute.

5.1 Three sentences to plant during sampling

Which spec version governs bulk (usually the confirmed sample version, or that version plus a production-tolerance annex);
Whether sample-versus-bulk differences are allowed (hand samples marked “appearance only” need a separate production standard);
Preferred payment and dispute path (if the first order will use Trade Assurance, specs and lead time must match order fields).

How to place quantity, lead time, and Incoterms correctly on a first TA order is covered in first Trade Assurance bulk order. This page’s job is to align version IDs and acceptance early so order creation does not reopen the fight.

5.2 Bookkeeping when sample fees credit into a TA order

If deductible credit applies, order remarks or an attachment should state amount already collected, credit applied, and remaining goods value. When platform fields and an offline side letter conflict, keep the version you can produce in a dispute, and supplement credentials per current rule-center guidance.

5.3 Photos and inspection evidence

Before ship, photograph or short-video the sample with the version ID in frame. After delivery, ask the buyer to tick the freeze form. Those artifacts usually outperform “we said so on WeChat” when bulk disputes appear later.

5.4 Incoterms and freight responsibility

Sample legs often use door-to-door express; bulk may switch to FOB or CIF. State who pays sample freight in the policy; for structural air-versus-ocean cost boundaries see ocean vs air for samples and bulk. Lock spec and payer first, then choose the channel—do not buy rush freight for an unfrozen unit.

6. Stop-loss when the buyer only samples

Some buyers sample to compare, tear down, test shelf placement, or simply exhaust suppliers. Policy must authorize exit—not moral pressure to keep chasing.

6.1 Suggested stop-loss triggers (tune numbers by category)

Critical fields still drift after the agreed revision rounds (illustrative: two rounds);
No written feedback within the stated calendar days after delivery, and no bulk intent or payment;
Refuses any fee while requesting many SKUs or many ship-to addresses;
Demands tooling or bulk scheduling without deposit and entity checks;
Same entity cycling sample asks across multiple accounts.

6.2 How to close in writing

Closure is not a threat. It records current version status, costs incurred, and conditions to reopen. A workable skeleton: thank the buyer → restate confirmed/unconfirmed version → state that free/paid quota is exhausted or stop-loss triggered → give reopen path (prepay, quantity band, version sign-off) → keep a quote validity window.

6.3 Handoff to overall inquiry stop-loss

Sample stop-loss is a subset of conversion stop-loss. If the lead already spent two quote rounds on price-only shopping or has no clear decision chain, downgrade earlier using the inquiries-but-no-orders playbook—do not ship first and regret later.

6.4 Failure sketches (illustrative)

Case 1: A lighting factory waived freight on 40 standard sets in three months and closed zero. No freeze forms, no monthly quota. Fix: waive sample fee on standards only with prepaid freight; max two sets per buyer per 90 days; beyond quota, full charge.

Case 2: A hardware factory waived tooling “for a big account”; the buyer took drawings elsewhere. Fix: tooling prepaid; ownership and confidentiality in the freeze annex; bulk deductible only via TA and a quantity threshold.

Case 3: Reps feared offense and kept reshipping to buyers who refused sign-off. Fix: warehouse gate live—no version ID, no outbound; KPIs shift from “samples shipped” to freeze rate plus sample-to-bulk rate.

Case 4: A plastics plant allowed “ship now, settle sample fees at month end” and failed to collect for two months. Fix: new buyers default to prepay before scheduling; open terms only for verified long-term entities with written limits; exceptions need manager approval and a stated expected collection date.

After stop-loss, teams worry about “scaring real buyers.” Check history: buyers who eventually order usually confirm specs or pay sample fees inside a reasonable window. Leads blocked by stop-loss typically free A-tier hours. One quarterly one-pager of that contrast beats slogan-level “customer first.”

7. A clause skeleton you can adapt

Use the skeleton below for on-platform copy and a PDF annex. Replace illustrative numbers and days by category.

7.1 Short buyer-facing blurb (illustrative)

“Samples ship only against a mutually confirmed spec version. Standard stock samples: sample fee / freight rules are … Custom and tooling: tooling and sample fees prepaid; may credit against first bulk per annex. Please confirm in writing within X days of delivery; if there is no confirmation and no bulk intent, later samples require full prepay. Deposit and deductible terms are in the annex.”

7.2 Internal execution checklist (weekly audit)

Every outbound sample this week has a version ID;
Free samples sit inside quota and tier;
Deposits/sample fees collected or collect agreed;
Stop-loss leads closed in writing;
Sample-to-bulk version IDs appear on quotes / TA remarks.

7.3 Fit with storefront and RFQ

Put a Sample Policy summary link or PDF on hero SKUs and in RFQ first replies to cut repeated explanation. Logistics attachment field craft lives in RFQ logistics practices on-site; the sample policy itself still rests on freeze forms and fee lines.

7.4 When to escalate human approval

Over-quota free samples, tooling waivers, multi-parcel ships to personal addresses, or controlled-market certification promises need manager approval. Drafting tools may generate English wording; send and release remain human actions.

7.5 Where to publish so buyers actually see it

Sync three places: (1) a short Sample note on hero SKU detail pages; (2) one fee-and-freeze sentence in inquiry/RFQ first-reply templates; (3) a downloadable full PDF including deposit and deductible. Burying the PDF deep in “About us” equals having no policy. Keep CN/EN version IDs aligned so English does not waive freight while Chinese charges.

Onboarding: new reps pass “freeze form + warehouse gate” before soft skills. Language can flex; gates cannot. Each quarter, sample ten shipments: missing version ID, uncollected fees, or over-quota free hits count as process defects—not only individual attitude.

7.6 Legal and documentation handoff

Tooling ownership, IP/confidentiality, and limits on reverse engineering belong to legal language; sales must not waive them orally. Documentation teams watch whether sample customs descriptions may conflict with later bulk HS codes, and whether consignee entity matches contracting entity. Mismatched entities invite questions on TA and customs—shipping to a personal name while contracting under a company name is a frequent trap.

8. Practical FAQ

Must every sample be paid? Does free always convert better?

Not always. Low-cost standard stock with a verifiable buyer and a frozen spec can justify waiving the sample fee (freight usually still buyer-paid). Custom work, tooling, and high-value materials default to paid. Always-free invites screenshot “obligations” and serial samplers. Closes come from clear specs and credible fulfillment, not unlimited free units.

What is the difference between a deposit and a deductible sample fee?

A deposit is risk cover you may retain on walk-away, refused freeze, or agreed breach. A deductible credits against goods value when bulk lands inside a validity window on an agreed path. Write separate triggers, timelines, and non-refund cases—do not merge them in chat.

The buyer is urgent—can we ship without a freeze form?

We advise against it. Unversioned shipments are a top source of “wrong goods” disputes. Use a rush fee to compress bench time; do not trade away confirmation for speed. Warehouse release should require the freeze form.

How should sampling prepare for a later Trade Assurance bulk order?

At sample time, state version ID, sample type (hand vs production-representative), acceptance/deviation, and whether fees can credit the first order. When opening TA, put the same version and critical terms into order fields or attachments. First-order mechanics are in the TA bulk guide.

What if a buyer keeps asking for samples and never orders?

Close on stop-loss in writing: quota or conditions triggered, later samples prepaid, reopen materials listed. Also apply overall inquiry stop-loss so you do not keep sampling price-only leads with no decision chain. Archive when needed and free A-tier hours.

Should the sample go air or ocean?

It depends on weight/volume, urgency, and whether the unit is only for confirmation. Structural choice and cost boundaries live in the ocean-vs-air samples/bulk article. On this topic, freeze the spec and who pays freight first, then pick the channel—do not pay for rush on an unlocked version.
