Sample policy depends on the part: standard carbide snow plow blades are usually sampled free or at a nominal charge with freight collect, while custom hole patterns, non-standard dimensions and private-label edges are quoted as paid samples with freight typically prepaid by the buyer and credited against the first production order. The exact split is confirmed in the formal quotation, not on this page.
What “sample” means for a cutting edge
A cutting edge sample is not a swatch. It is a finished wear part with a specific steel grade, carbide grade, bevel geometry, hole layout and tolerance stack, so the cost of producing one is closer to a small production run than to a catalogue mailer. Buyers should treat the sample request as a mini order with its own specification and its own freight decision.
In practice, most requests fall into one of three buckets: a catalogue reference sample, a fitment sample for a specific truck or plow model, and a pre-production sample that will be inspected and then released for volume. Each has a different commercial treatment.
Free samples: when they apply
Free sampling is normally limited to catalogue items that already exist as stock or near-stock, where no new tooling, drilling program or laser nesting is required. The manufacturer absorbs the part cost; the freight question is where most of the negotiation sits.
- Catalogue reference edge — usually free of charge, one or two pieces per buyer, subject to stock availability.
- Freight — commonly collect on the buyer’s account, or prepaid and added to the next invoice. Courier, air and sea are quoted separately.
- Documentation — material certificate, hardness range and dimensional report are normally included at no cost.
- Limits — free samples are generally not repeatable for the same buyer and are not intended for field trials across a whole fleet.
Because a carbide edge is a dense, heavy item, freight can approach or exceed the part value on small parcels. That is why the freight term is stated explicitly rather than assumed.
Paid samples: when they apply
Paid sampling applies whenever the request touches tooling, custom geometry or branding. The charge covers setup, material and inspection time, and it is quoted case by case rather than published as a fixed price.
- Custom hole layout or bolt pattern — new drilling or punching program, first-article inspection included.
- Non-standard dimensions — length, width, thickness or bevel angle outside the catalogue range.
- Private label or laser marking — artwork setup and marking program.
- Carbide grade trial — a specific grade or insert geometry requested for a wear comparison.
- Pre-production sample — a full specification sample intended for approval before a volume release.
Sample charges are frequently credited against the first production order above a stated quantity, but that credit is a commercial term and must appear in the quotation. Do not assume it.
Who pays freight, and how it is usually structured
Freight is the most common source of misunderstanding in sample discussions, because the part may be free while the transport is not. The table below reflects the arrangements most often used in B2B edge supply; the actual term for a given order is set in the formal quotation.
| Sample type | Part cost | Freight | Typical credit |
|---|---|---|---|
| Catalogue reference edge | Free, limited quantity | Buyer account or collect | None |
| Fitment sample, standard holes | Free or nominal | Buyer pays; may be prepaid and invoiced | Sometimes against first order |
| Custom hole pattern / dimensions | Paid sample charge | Buyer pays unless quoted DDP | Often credited above a minimum order quantity |
| Private label / marked edge | Paid, includes setup | Buyer pays | Case by case |
| Pre-production approval sample | Paid, may be higher | Negotiated per quotation | Credited on volume release |
Incoterms matter here: EXW, FOB and DDP shift both cost and customs responsibility. A buyer comparing two sample offers should compare the landed cost, not the part price.
Commercial reality: MOQ, lead time and specification risk
The sample decision is really a supply decision. A free sample that arrives in three weeks may cost more in schedule terms than a paid sample that arrives in ten days, and a sample built outside the eventual production process can hide a specification risk that only appears at volume.
Three points are worth settling before the sample ships. First, MOQ: sample credit usually attaches to a minimum production quantity, so confirm that number early. Second, lead time: sample turnaround and production turnaround are separate clocks, and both depend on material availability and current shop load. Third, specification risk: the sample should be produced on the same process route as production — same steel source, same carbide grade, same bevel method — otherwise the approval does not transfer. Quotation, MOQ, tooling cost and lead time are all confirmed in the formal quotation; the product page is a reference, not an offer. Buyers who want to understand how edge condition is judged in service can read the field notes on edges and in-pavement lights strike checks.
How to request a sample without a second round of emails
A complete request shortens the quotation cycle. Include the machine or plow model, the OEM part number if one exists, the drawing or hole layout, the quantity you expect to buy annually, and the destination port or address. State whether the sample is for fit check, wear trial or customer approval, because that changes what inspection report is issued with it.
For carbide-specific requests, reference the carbide snow plow blade range so the sample is quoted against the correct base specification. If the request is for a mixed fleet, list each model separately; a single sample cannot validate several hole patterns. Check the drawing and hole layout on the product page before ordering.
Quick summary
Catalogue carbide edges are generally sampled free with freight on the buyer’s account, while custom hole patterns, non-standard sizes and private-label edges are paid samples, often credited against a first production order above a stated MOQ. Freight is negotiated separately and should be compared on a landed-cost basis. All figures, including sample charge, MOQ, tooling and lead time, are confirmed only in the formal quotation.
