Your supplier decides your margins, your consistency and how often you deal with complaints. In a consumable category like cat litter, an unreliable factory doesn't just cost you one order — it costs you the repeat business that makes litter worth selling. This checklist walks through what actually separates a dependable manufacturer from a risky one.
1. Do they control their own mine source?
Bentonite quality starts at the mine. A manufacturer that owns or directly controls its mineral source has steadier raw-material quality, more predictable lead times and more stable pricing than a trader buying material batch-to-batch on the open market. Ask directly: Do you mine or process your own bentonite, or buy it in? The answer tells you a lot about how consistent your product will be a year from now.
2. Can they prove quality with a COA — not just a spec sheet?
Anyone can send a glossy spec table. What matters is a Certificate of Analysis (COA) showing actual tested values for real batches: clumping rate, water absorption, dust content, moisture, granule size, deodorization and pH. A supplier confident in its product will share COAs readily. Bracketed "tested" figures next to the standard (e.g. "≥300%, tested 311%") are a good sign — it means they measure, not just promise.
3. How wide is their real customization range?
A strong OEM partner should be able to adjust granule size, clumping grade, color, scent, additives (like activated carbon) and packaging. Ask to see the range of products they already make. A factory that produces clumping ball litter, granular and crushed mineral litter, activated-carbon and colored/scented lines can serve several of your markets from one relationship — and adapt as your catalog grows.
4. Do they have genuine export experience?
Selling domestically and exporting are different disciplines. An export-ready factory containerizes and palletizes correctly, provides complete and accurate documentation (invoice, packing list, certificates), and understands the requirements of import-dependent markets. Ask which countries they already ship to and whether they've handled your destination before. Smooth customs clearance is worth as much as a good price.
5. Are samples and communication fast and clear?
The sampling stage is a preview of the whole relationship. A responsive supplier turns your specs into tailored samples quickly and answers technical questions directly. Slow, vague replies before you've even placed an order rarely improve after you have.
6. Is the MOQ realistic for how you want to start?
If you're entering a new market, you want to test before you commit. Look for a supplier that supports trial orders and mixed containers — several SKUs in one 20-foot load — rather than one that insists on a full container of a single product. Flexibility here signals a factory that understands brand-builders, not just bulk buyers.
7. Do the economics actually work?
Litter is priced by weight and volume, so compare on landed cost per kilo, container loading efficiency (how many tonnes fit a 20'GP), packaging cost and freight — not just the headline FOB number. A slightly higher unit price with better clumping and lower dust can mean fewer complaints and more repeat orders, which is where the real money is.
Red flags to watch for
- Won't share a COA, or the "COA" has no actual tested values.
- Can't clearly answer whether they own their source.
- Every question gets a vague "yes, no problem" with no specifics.
- No export references and no experience with your destination market.
- Pushes a huge single-product MOQ with no trial option.
- Sample quality doesn't match the spec sheet they sent.
Questions to ask on your first call
- Do you mine and process your own bentonite?
- Can you send a COA with actual tested batch values?
- What can you customize — granule, clump grade, color, scent, packaging?
- Which markets do you export to, and have you shipped to my country?
- What's your MOQ, and can we start with a mixed trial container?
- What's your typical lead time from confirmed order to shipment?
