OEM Cat Litter Custom Formula Process: 30-45 Day Timeline

Day 0 starts at artwork sign-off, not at deposit

The most common scheduling mistake on a first private-label order is treating the deposit wire as Day 0. It is not. Day 0 on our production calendar is the day artwork is signed off and the rotogravure plates can be cut. Everything before that is variable; everything after that runs on a deterministic schedule that we meet on something like 92% of POs.

The full window from inquiry to FOB-ready is 30 to 45 days, with the spread driven almost entirely by how fast the buyer's side moves on artwork revisions and formula confirmation. Brands that hit the bottom of the window have artwork ready and a confirmed formula by the time they wire the deposit. Brands that hit the top of the window are still iterating bag designs three weeks in. Both are workable; the cost difference is a meaningful chunk of cash flow.

Day 0–5: inquiry, sample, formula confirmation

The first five business days are a structured intake conversation. We do not start a production calendar until both sides have signed off on the four numbers below.

What we ask on Day 1

• Target retail format (6 lb pouch, 18 lb retail bag, 36 lb family pack, 40–50 lb bulk for B2B)
• Target formula (Cassava + Tofu Blend, Pure Pea-Fiber Tofu, Pure Cassava with custom binder)
• Cassava-to-tofu ratio if outside the 70:30 default (50:50, 60:40, 80:20)
• Scent (unscented default, apple-mint, lavender, custom EO)
• Activated-carbon loading (0% default, 0.5%, 1.5%, 3% by weight)
• Target case quantity and incoterm preference (FOB / DDP)
• Brand artwork status (concept / draft / press-ready)

What we ship on Day 3 to 5

Sample bags of the agreed formula go out by international express (DHL or FedEx) on the second business day after the intake call. Transit to most US destinations is 3 to 5 business days. The sample includes the agreed cassava-tofu ratio, scent, and carbon loading; it does not include custom artwork (samples ship in our standard RootPurr unmarked bag with a printed lot identifier).

Sample shipping is at our cost on inquiries from buyers we have either spoken with on a call or who have completed the wholesale inquiry form with verifiable business contact details. We do not ship samples on cold inbound emails with no business context; that is a basic anti-fraud measure, not a commercial gate.

Formula confirmation gates the next step

The buyer signs off on the sample by Day 5 to keep the schedule. If the sample needs an adjustment (different ratio, scent change, carbon level shift), we cycle a second sample within 7 days and the calendar resets to Day 0 on the second sample sign-off. Adjustments are normal on first orders; they cost time, not money.

Day 5–14: artwork proof, dieline, plate-making

With formula locked, the next nine days are a parallel-track artwork process. We provide the dieline (the bag template with bleed, safe area, seal zones, and barcode placement marked), the buyer provides the artwork inside it.

Day 5: dieline + artwork spec sent

We send the dieline as a layered PDF and AI file with bleed at 3 mm, safe zone 5 mm inset, and the production-mandated regulatory text (lot identifier, weight, country of origin) marked as a non-editable layer. We accept artwork in vector AI, EPS, or PDF/X-1a with all fonts outlined and images embedded at 300 DPI minimum at print size. Pantone solid-coated callouts are required for any spot colours.

Day 8 to 10: artwork proof iterations

First proof goes out within 2 business days of receiving usable artwork. Most buyers iterate one or two rounds: a colour adjustment, a typography tweak, a barcode placement shift. Each round adds 1 to 2 business days. Brands that send press-ready artwork on Day 5 typically lock the proof on Day 8; brands that send conceptual artwork iterate through Day 12 or 14.

Day 12 to 14: rotogravure plate-making

Once the buyer signs off on the digital proof, we cut rotogravure plates: one cylinder per colour separation, six cylinders for a standard 6-colour bag. Plate-making is mechanical (laser-engraved copper-plated cylinders) and takes 2 to 3 working days. Plate cost runs $300 to $600 per cylinder and is invoiced separately on the proforma. Plates are stored at the factory for re-runs at no charge for 18 months from the last use; beyond that, plates may need re-cutting if the bag has been retired from active production.

Day 14–35: production with QC checkpoints

With plates cut and formula confirmed, the production run starts on the dedicated line. A 1 × 40HQ FCL of cassava blend (~1,500 cases at 18 lb) takes approximately 14 to 18 working days through production. The main steps:

Cassava lot intake and HCN test (Day 14 to 16)

The cassava starch lot for your run is tested on the alkaline-picrate method before it touches production equipment. Internal threshold is ≤ 5 ppm HCN, half the FAO/WHO food-grade limit. Lots above 5 ppm are returned to the supplier; we do not run them even if it pushes the schedule. The test result becomes part of your shipment's document folder. See the cassava pillar guide for the full method description.

Blending, extrusion, drying (Day 16 to 28)

The agreed cassava-to-tofu ratio is dry-blended, hydrated to a controlled moisture target, extruded through the pellet die at the agreed pellet size (1.5 to 2.0 mm), and dried in a counter-flow drier to ≤ 8% moisture. The line throughput is roughly 80 to 120 cases per shift hour depending on format; an FCL usually takes 2 to 3 production shifts spread over the window.

ASTM D6940 dust test on the lot (Day 28 to 30)

A sample from the production lot goes to the ASTM D6940 dust-test protocol. Cassava blends typically run at ~99% reduction relative to the bentonite reference; pure tofu at ~99.4%. The lab report names the testing facility, the reference material, the sample lot, and the date. It joins the document folder.

Bagging, casing, palletisation (Day 30 to 35)

Pellets are bagged into your custom-printed bags, heat-sealed, cartoned (1 bag per carton for retail, ECT-32 single-wall corrugated kraft), and palletised at 5 cartons per layer × 9 layers = 45 cartons per pallet. Palletised cases are floor-loaded into the 40HQ to maximise cube utilisation; we get approximately 22 pallets into a 40HQ on the standard configuration.

Day 35–45: export inspection and FOB handoff

The final 7 to 10 days cover document preparation, export inspection, inland transport to the loading port, and FOB or DDP handoff. The work is administrative; the schedule risk here is smaller than in the production window.

Document folder

• Per-batch Certificate of Analysis (moisture, particle size, bulk density, clumping time, lot ID)
• HCN test report on the cassava starch lot
• ASTM D6940 dust-reduction report
• Commercial invoice with HTS code declared (1404.90.9000 for cassava blends, 1108.14.0000 where applicable for pure starch)
• Packing list, bill of lading, certificate of origin
• Cargo insurance policy (DDP shipments only)

Inland to Tianjin / Qingdao

Trucking from our Xingtai production line to Tianjin (Xingang) runs ~280 km and takes one day. Qingdao is ~640 km and takes 1.5 to 2 days. Tianjin is the default loading port; Qingdao is used when the buyer's forwarder has stronger Qingdao space allocation in the loading window.

FOB or DDP handoff

On FOB, our liability ends as the container loads onto the vessel; the buyer's forwarder takes over from there. On DDP, we own the container through US customs clearance and inland delivery to the buyer's 3PL. For the cost-comparison side of this decision, see the FOB vs DDP landed-cost breakdown.

Common delays and how to avoid them

Five recurring failure modes account for almost all schedule slip on first POs. Each is preventable by the buyer.

• Artwork sent as a flat PSD or low-DPI JPG. Adds 4 to 7 days while the buyer re-exports vector artwork. We catch this on Day 6; the cost is a week of slipped lead time.
• Pantone callouts not provided for spot colours. We can pull approximate colours from the artwork file, but rotogravure ink mixing without Pantone callouts produces a best-effort result that the buyer either accepts or pays to re-print. Specify Pantones up front.
• Mid-run artwork changes. A typography change discovered on Day 25 means new plates ($300 to $600 per colour), production pause, and a 5 to 7 day push on the schedule. Lock the proof before plate-making, not after.
• Late deposit wire. Production starts on deposit-clearance plus artwork sign-off, whichever is later. A deposit wired on Day 14 but artwork signed-off on Day 8 puts the calendar on Day 14. Wire early; chase the artwork in parallel.
• HCN result above threshold on the cassava lot. Rare (lots are pre-screened by our supplier) but it happens. When it does we pull a different lot, retest, and lose 3 to 5 days. The alternative is to ship a lot above our threshold, which we will not do.

Rush options (and their honest cost)

Two compression levers exist. Neither is free and neither saves more than ~5 days off the standard window.

Pre-printed bag inventory. If the buyer is willing to use already-printed RootPurr retail bags (no custom artwork), the artwork and plate-making window collapses to zero. Production starts on Day 5 instead of Day 14, FOB-ready in ~25 days. Trade-off: not your brand on the bag.

Air freight on a partial load. For brands with a promotional deadline, we can air-freight a 100-to-200-case partial load while the FCL ships ocean. Air freight is roughly 8 to 12× the per-pound cost of ocean and rarely makes sense for anything beyond launch-day inventory; we mention it for completeness.

Bottom line

Plan on 30 to 45 days from artwork sign-off to FOB-ready. The bottom of the window is achievable when artwork is press-ready and formula is locked at intake; the top of the window is where most first orders land. The schedule is deterministic after Day 14; before Day 14, it depends on how fast the buyer's side moves on revisions.

The other half of the buyer relationship is the documentation set we deliver with every shipment; the 14-point private-label checklist walks through what to verify on the proforma.
