15 Questions to Ask a Cat Litter Factory Before Your First Bulk Order

How to verify: ask for the factory business license (verify with the issuing authority), production video walkthroughs dated within the last 30 days, and a list of active OEM clients you can contact for reference. Most professional factories have a public audit report (BSCI, Sedex, or customer-initiated).

Watch out: if the type you want is subcontracted to another facility, ask who controls quality and how issues are resolved. A factory that owns the full production chain for your selected product makes accountability simpler to verify.

Key OEM questions to ask: (1) Who owns the mold/tooling for your custom packaging — you or the factory? (2) What is the artwork proof turnaround? (3) Is there an exclusive formula clause, or can the factory sell the same formula to your competitors? (4) Does the factory provide free design support, or is it billed separately?

A serious factory should be able to: (1) name their main raw material suppliers and the relationship duration; (2) provide incoming inspection records for the last 3-6 months; (3) explain how they handle material variation between batches; (4) show storage conditions (humidity-controlled warehouses matter for plant-based litter).

Ask for: (1) the documented QC checkpoints from incoming material to pre-shipment; (2) the test report template, including granule size distribution, dust percentage, clumping time, water absorption (%), moisture content (%), and pH value where applicable; (3) how batch-specific results are recorded and shared with each shipment. Reject any supplier that only does "visual inspection" without instrument-based testing.

A robust consistency program includes: (1) retained samples from every batch stored for 12+ months; (2) batch code traceability from raw material to finished goods; (3) statistical process control charts on critical parameters; (4) third-party lab verification at least quarterly. Ask to see 2-3 batch test reports from different production dates — consistency tells you more than a single good sample.

Ask about: (1) Maximum output per production line per shift; (2) Number of shifts and seasonal variation; (3) Lead time during peak season (Q4 typically); (4) Backup capacity for unexpected demand spikes; (5) Current capacity utilization rate. A factory running at 70-80% utilization has flexibility; one at 95%+ will struggle to grow with you.

Key packaging specs to clarify: (1) Bag material thickness and barrier properties (oxygen/moisture); (2) Available printing methods (flexo vs digital) and color count; (3) Closure type (zipper, heat seal, valve); (4) Shelf life guarantee under your storage conditions; (5) Pallet configuration and 20ft/40ft container loading plan to optimize shipping cost.

What to confirm in writing: (1) the MOQ per SKU, not just per container; (2) whether mixed-SKU loading is possible for a trial order; (3) how the unit price changes between trial and repeat quantities under the same trade terms; (4) which packaging choices (printed bags, barcodes, pallet configuration) affect the minimum. A factory that explains its MOQ structure is easier to plan with than one quoting a single take-it-or-leave-it number.

Hidden delays to watch for: (1) artwork proof approval — buyers often take longer than expected to confirm; (2) raw material procurement — out-of-stock additives can extend preparation; (3) peak season queuing — confirm current line availability before placing the order; (4) freight booking — sailing schedules and transit times vary by route and season. Ask your supplier to quote each milestone for your exact specification and destination, then build your inventory buffer around the confirmed schedule rather than a generic number.

For your target market, ask for relevant shipment experience, packaging requirements and examples of documents the supplier can provide. Confirm which requirements apply to the selected product and destination with the responsible importer or qualified adviser.

Strong ODM partners offer: (1) trend reports based on export data and customer feedback; (2) in-house lab for clumping, dust, and absorption testing; (3) small-batch pilot production before committing to container orders; (4) joint product development with confidentiality agreements. A factory that can only execute your spec, not improve it, limits your long-term competitive advantage.

Verify the issuer, validity, scope and product or facility covered by each document. Separate management-system certificates from product test reports and shipment documents. A generic certificate list is not a substitute for checking the exact order requirements.

Communication red flags: (1) replies taking 2+ days during business hours; (2) using machine translation with grammar errors in technical documents; (3) multiple contact points with conflicting information; (4) no scheduled production updates. Best practice: establish a weekly update call (15 min) covering production progress, QC results, and any issues. The best factories proactively flag potential delays rather than waiting for you to ask.

How to compare fairly: (1) send every shortlisted supplier the same specification and trade terms; (2) ask each to itemize what the price includes and excludes; (3) add your own freight, inspection and inventory estimates for a landed-cost view; (4) then negotiate among the 2-3 suppliers whose evidence (not promises) satisfied the first 14 questions. The goal is the lowest total cost at a quality level you can defend to your customers — not the lowest number on a quote sheet.
