Quick Answer
A distributor is not buying a product catalogue. It is buying four things that a catalogue cannot show:
- A gap it can fill — SKUs that its current range does not cover, without duplicating what already sells.
- Continuity — the same formulation, the same packing, the same lead time, on the fourth order as on the first.
- Margin protection — price stability, and a supplier who does not sell around you in your own market.
- Documentation it can hand to its own customers — datasheets, certificates and declarations that hold up when a project asks.
Most distributor-supplier relationships fail on the second and third, not the first. That is worth remembering when a new supplier’s catalogue looks perfect.
1. Start With a Gap Analysis, Not a Price List
Before evaluating any supplier, write down what your range cannot do today. A useful frame:
| Category | Question | Consequence if unresolved |
|---|---|---|
| Coverage | Which application types do I turn away? | Lost basket, customer goes elsewhere |
| Depth | Do I have one SKU or a tier per application? | Cannot trade up; margin stuck at entry level |
| Overlap | Which new SKU competes with one I already stock? | Double inventory, split demand |
| Adjacency | Does the range pull through accessories, primers, tools? | Lower basket value per order |
Compare candidate suppliers against that list, not against each other’s catalogues — and start from the product categories rather than from a single model. A supplier that fills three real gaps is worth more than one that offers sixty SKUs, forty of which you already have.
The portfolio structure used by distributors in this category — how many tiers per application, and where to hold stock — is set out in how to build a construction adhesive and sealant distributor portfolio.
2. Continuity: the Part That Is Never in the Quotation
Continuity has three testable components.
Minimum order per model. A supplier quoting per pallet forces you to think in pallets, not units. In this range, a standard model’s minimum is 1,920 sausage packs or 3,840 cartridges per model, which is two pallets — a useful number to sanity-check your warehouse layout against before you commit to a broad range.
Lead time and its starting point. “3–4 weeks” means nothing without an origin. Ours is measured from receipt of the deposit, and custom colours add roughly one to two weeks. A supplier who quotes lead time from “order confirmation” and then starts the clock at artwork approval has told you the real number already.
Continuity assumes the factory can be verified in the first place; how to qualify construction adhesive manufacturers in China covers the audit side, which is a different question from range fit.
Substitution risk. Ask what happens when a raw material changes. A supplier that reformulates quietly, and ships the new version under the same code, will eventually put a product into a project that specified the old one. Ask for the change-notification policy in writing — it is a better predictor of reliability than any certificate.
3. Margin Protection Is a Contract Question, Not a Price Question
Three mechanisms decide whether a distribution margin survives the first year:
| Mechanism | What to ask | Why it matters |
|---|---|---|
| Price validity | How long is a quoted price held, and what index drives changes? | Protects you against a mid-project increase |
| Channel discipline | Do you sell direct into my market? Through marketplaces? | A supplier selling around you sets your ceiling price |
| Territory | Is there any protection, and on what basis is it granted? | Understood in writing, reviewed periodically |
On territory, be precise about what is and is not promised. Exclusivity in this category is normally discussed per market and against a committed volume — it is not granted on a first order, and it should never be assumed from a friendly conversation. If a supplier promises exclusivity verbally on the first call, that is a warning sign about how they treat agreements in general.
4. Documentation Burden: Multiply by SKUs and by Markets
A distributor does not need one datasheet. It needs one per model, per market, in a language its customers read.
Before signing, count the documents:
- TDS per model, with test methods stated.
- SDS per model, in the destination language, with correct transport classification — aerosols and PU foams carry restrictions that affect how you ship samples and how your customer stores stock.
- Declarations per market: for outdoor construction products, CE and ISO 9001 with ISO 11600 are the baseline; RoHS is commonly requested. Indoor products add a different set.
- Test reports where a project requires them, scoped to the model and substrate in question.
Then ask who maintains them. A supplier who treats documentation as a one-time deliverable will leave you with a folder of expired revisions in two years — and project submittals that fail on a date rather than on performance.
5. Commercial Terms That Actually Decide the Deal
- Payment structure. The standard basis in this range is 50% deposit with 50% before shipment. If your market cannot work with that, say so early: it is a commercial negotiation, not a technical one, and it is far easier before the specification is written around a product.
- Samples. Standard models are normally supplied free of charge, limited in quantity, with freight at the buyer’s cost — enough for a site trial, not enough to build a stock position.
- Private label threshold. Packaging, artwork and plate-making change both the minimum quantity and the lead time — see the OEM and private label overview for how that route differs from standard supply. Ask for the threshold and the sampling process together, because they interact.
- Price basis. EXW, FOB or delivered — and which port. A quotation without an Incoterm is not comparable to anything.
6. A Scorecard That Makes the Decision Auditable
| Criterion | Weight | What evidence satisfies it |
|---|---|---|
| Fills real range gaps | 25% | Written gap list mapped to specific SKUs |
| Continuity and change control | 20% | Change-notification policy, batch traceability, stable specifications |
| Documentation completeness | 20% | Current TDS/SDS per model, per market, with test methods |
| Commercial terms | 20% | Incoterm, payment, price validity, territory basis — all in writing |
| Technical support | 15% | Named contact, response time, willingness to review a project detail |
Score two or three candidates on the same sheet. The exercise is less about the winner than about seeing which criteria you are actually weighting — most distributors discover they were weighting price twice.
7. Red Flags Worth Walking Away From
- A catalogue with more SKUs than the factory can plausibly produce.
- Datasheets that quote figures without test methods, or that share one figure across several models.
- Lead time quoted without a starting point.
- Exclusivity offered before volume is discussed.
- No named technical contact — only a sales address.
- Reluctance to send a current SDS, or an SDS in a language nobody in your market reads.
Discuss Your Distribution Requirements with INGADA
If you are evaluating suppliers for a regional distribution range, prepare the gap list, the applications you turn away today, your warehouse and pallet constraints, the markets you serve and the documentation each of them requires.
INGADA can confirm which models fill those gaps, what the minimum order looks like per model, and which documents are available for your markets — and will say plainly where a requirement cannot be met.
Commercial terms, territory arrangements and lead times are confirmed per market and per order. Nothing in this article constitutes an offer of exclusivity.
