Private Label Cat Litter Manufacturer: Complete Buyer Checklist

The 14-point checklist at a glance

A workable private-label cat-litter agreement is built from documents and specifications, not from email rapport. Below are the fourteen line items every US pet brand should put on the table before signing with a Chinese manufacturer. The order matters: documentation first, because it is the cheapest item to falsify and the most expensive to discover missing after a container has shipped.

1. Per-batch Certificate of Analysis (COA)
2. Hydrogen cyanide (HCN) test report on every cassava lot
3. ASTM D6940 dust-reduction report
4. HTS code declared on the commercial invoice
5. Minimum order quantity for both custom-printed and pre-printed runs
6. Lead time from artwork sign-off to FOB-ready
7. Payment terms (deposit, balance trigger, currency)
8. Custom formula range (cassava-to-tofu ratios available)
9. Custom scent and activated-carbon options
10. Bag and carton specification (artwork format, dielines, weights)
11. Incoterm option (FOB or DDP) and the loading port
12. Container utilisation and mixed-SKU flexibility
13. Cargo insurance and damage-claim handling
14. Single dedicated production line (or the absence of one)

The rest of this guide expands each cluster, with the numbers we actually run at RootPurr, the questions we expect a serious buyer to ask, and the red flags worth walking away from when a prospective supplier cannot answer cleanly.

Documentation: COA, HCN, ASTM D6940, HTS

Every shipment we send leaves the factory with four documents in the export folder: the per-batch Certificate of Analysis, the HCN test report (on cassava lots only), the ASTM D6940 dust-reduction report sampled from the same production run, and a commercial invoice with the correct US Harmonised Tariff Schedule code declared. Three of the four are non-negotiable before goods leave the production floor; the HTS code is non-negotiable before the bill of lading is cut.

Certificate of Analysis (per batch, not per program)

A real COA is per production batch and is dated to that batch. If a supplier sends you the same COA twice for two different shipments, you are looking at a marketing document, not a quality record. The COA should list moisture content, particle size distribution, bulk density, clumping time, and the lot identifier printed on the carton case mark. Match the lot identifier on the COA to the case mark on delivery; if they differ, raise the discrepancy before signing the delivery receipt.

HCN report (cassava only, ≤ 5 ppm internal)

Raw cassava root contains cyanogenic glycosides that release small amounts of hydrogen cyanide during processing. The FAO/WHO food-grade limit on finished cassava products is 10 ppm. Our internal threshold is 5 ppm, half the food-grade limit, tested on every starch lot using the alkaline-picrate colorimetric method before the starch reaches the production floor. Any prospective supplier offering cassava-based litter who cannot produce a per-lot HCN report on request is a fail. See the cassava cat litter pillar guide, section 3, for the full method description.

ASTM D6940 dust report (sampled, not asserted)

ASTM D6940 is the recognised standard for dust reduction in pet litter. The test compares aerosolised particulate generated by a sample against a sodium-bentonite reference. Both our cassava blend and pure tofu lines run at ~99% reduction, with tofu averaging ~99.4%. A real D6940 report names the testing lab, the sample lot, the date, and the reference material. A claim of “99% dust-free” on a marketing slick with no method, no reference, and no date is not the same artefact and should not be treated as one.

HTS code on the commercial invoice

The HTS code determines your duty rate and your customs broker's ability to clear the container without a query. We declare 1404.90 for the cassava blend (vegetable products not elsewhere specified) and 1108.14for pure tofu (manioc starch). A supplier who shrugs at HTS classification and writes “cat litter” in the description field is exporting a problem that lands at your broker's desk. Get the code on the proforma invoice before you wire the deposit.

MOQ, lead time, payment terms

Three numbers anchor the commercial side of any private-label agreement. Get all three in writing on the proforma invoice; do not accept “flexible” as an answer for any of them.

MOQ: 1 FCL custom-printed, 50 cases pre-printed

Our minimum order is 1 × 40HQ FCL (~1,500 cases at 18 lb / case, ~27,000 lb total) for custom-printed bags on either the cassava blend or the pure tofu formula. For brands trialling the product before committing to a full container, we sell already-printed RootPurr retail bags down to 50 cases. Suppliers offering a meaningfully lower MOQ on custom-printed runs are usually consolidating your artwork with another buyer's, which compromises the quality controls that come with a single dedicated line.

Lead time: 30 to 45 days from artwork sign-off

Artwork sign-off, not deposit receipt, starts the clock. The window breaks down roughly as: 5 days for sample and formula confirmation, 9 days for artwork proofing and rotogravure plate-making, 21 days for production with QC checkpoints, and the balance for export inspection and FOB handoff. Brands that miss artwork deadlines push lead time outward day for day. Brands that change artwork mid-run eat the cost of new plates (~$300–$600 per colour separation).

Payment: 30% deposit, 70% against bill-of-lading copy

Standard terms are 30% T/T deposit on order confirmation, 70% T/T balance against scanned copy of the bill of lading, all in USD to a US-domiciled receiving account. We do not run open account on first orders; we do not accept letters of credit on first orders (the documentary cost outweighs the value of the guarantee on container-scale shipments). Repeat customers can negotiate net-15 or net-30 from the second purchase order onward.

Custom formula capability

A real OEM partner adjusts the formula to your retail positioning, not the other way around. Two formula levers move the most.

Cassava-to-tofu ratio (50:50 to 80:20)

Our default Cassava + Tofu Blend is 70:30. We run custom ratios from 50:50 (the softest pellet, the strongest clump, slowest clumping speed) through 80:20 (the lightest weight per cubic foot, the fastest clumping, the firmest pellet for shipping integrity). Most US retail brands settle around 60:40 or the default 70:30. We do not run pure cassava (100:0) on the standard line because the binder chemistry needs adjustment; pure cassava is available as a separate retail line with its own custom plant-binder spec, also available as an OEM custom binder system from 1 FCL.

Scent and activated-carbon options

Scent options include unscented (default), apple-mint, lavender, and custom essential-oil blends supplied by the buyer. Activated-carbon loadings run from 0% (default) to 3% by weight, in 0.5% increments; carbon is added to the pellet, not surface-coated, so it does not rub off in the bag. Both customisations affect cost per FCL on the order of a few percentage points; specific quotes are provided on the proforma invoice. We do not produce bentonite cat litter under any private-label arrangement.

Bag and carton specification

The packaging spec is where most first-time private-label inquiries underestimate the work. Plan to spend two weeks on artwork iteration before a single bag is printed.

Accepted artwork formats: vector (Adobe Illustrator AI, EPS, PDF/X-1a) with all fonts outlined and all images embedded at 300 DPI minimum at print size. Pantone solid-coated callouts for any spot colours. Photoshop PSD files are accepted only for raster image content placed inside a vector container; we do not print from a flat PSD. We provide the dieline; you provide the artwork inside it. Bleed is 3 mm on all edges; the safe zone for critical content (logo, regulatory text, barcode) is 5 mm inset from the dieline.

Bag construction is a 6-colour rotogravure-printed PE/PET laminate with a tear-notch top and a heat-sealed bottom. Standard retail sizes are 6 lb, 18 lb, and 36 lb; bulk B2B is 40 lb and 50 lb. Cartons are corrugated kraft, single-wall, ECT-32, packed 1 × 18 lb bag per carton for retail or 1 × 40-50 lb bag per carton for bulk. Pallet pattern is 5 cartons per layer × 9 layers = 45 cartons per pallet on a standard 48 × 40 inch pallet, floor-loaded into a 40HQ to maximise cube utilisation.

Shipping: FOB, DDP, port selection

We quote on either incoterm. Each has a distinct economic profile; the right answer depends on whether you have an existing US customs broker relationship and whether you have the patience to manage the inland leg yourself.

FOB Tianjin or Qingdao (recommended for established importers)

Free on Board out of Tianjin (Xingang) or Qingdaohands the container to your nominated forwarder at the loading-port rail. Tianjin is closer to our Xingtai production line (~280 km of inland trucking versus ~640 km to Qingdao); we default to Tianjin unless the buyer's forwarder has stronger Qingdao space allocation. FOB is the standard option for buyers with an existing US customs broker, an existing forwarder agreement, and the in-house bandwidth to handle the US inland leg.

DDP to a US 3PL (recommended for first-time importers)

Delivered Duty Paid lands the container at your nominated US 3PL warehouse with all duty, freight, and customs handling pre-paid by us. Standard US destinations are Los Angeles / Long Beach, Houston, New York / Newark, and Savannah. DDP is the right choice for first purchase orders where the buyer has not yet retained a customs broker; the trade-off is a slightly higher all-in price (~5–9% depending on lane), against which you save the management overhead of building two new vendor relationships.

Container utilisation and mixed-SKU flexibility

A 40HQ holds approximately 1,500 cases of 18 lb retail format, or a proportional mix across 6 lb, 18 lb, and 36 lb. We accept mixed-SKU loads at no added per-case cost provided the total cube fills the container; partial-cube loads are accepted with a flat consolidation surcharge that we quote on the proforma. LCL (less than container load) is available for trial orders below the FCL MOQ, with the standard caveat that LCL adds 8–14 days of deconsolidation time at destination.

Insurance and damage handling

Cargo insurance on FOB shipments is the buyer's responsibility; on DDP shipments it is built into the rate at 1.1× CIF value through Institute Cargo Clauses (A) wording. Either way, ask the question explicitly on the proforma. A surprising number of small-volume buyers ship FOB without insurance and discover the gap when a container is dropped at the rail.

Damage claims should be raised within 7 calendar days of delivery to the destination warehouse, with photographs of the carton condition, the case mark, the lot number, and where applicable the seal number on the container. We replace damaged units in the next purchase order at no charge, or credit the invoice, at the buyer's option. Disputes over moisture damage need to be raised before the cartons are unstacked, because pallet position changes the evidentiary picture.

Red flags to walk away from

Six recurring patterns separate a real OEM partner from a trading company that will subcontract your order out the back door. If you see any of these, ask twice; if you see two, walk away.

• No HCN report on request. This is the most load-bearing single test on a cassava-based product line. A supplier who cannot produce a per-lot result is either not testing or not testing in-house, both of which are disqualifying.
• The same COA twice. A genuine COA is per batch. Identical reports across separate shipments mean the document is a marketing artefact, not a quality record.
• No single dedicated production line. Plant-based cat litter shares almost no equipment with bentonite cat litter, but it does share equipment with several other extruded pet products. A supplier who runs your cassava blend on a line that ran rabbit pellet feed last week is one cross-contamination incident away from a recall.
• Vague MOQ language.“Flexible MOQ, depends on the order” usually means the supplier intends to consolidate your custom artwork onto somebody else's scheduled run. Demand a specific case count.
• HTS code answered with a shrug. If the supplier cannot tell you the HTS code on a proforma invoice, they have shipped this product without classification before, which is your customs-broker problem the moment the container lands.
• Marketing claims without methods.“99% dust-free” with no D6940 report. “Septic-safe” with no binder-system disclosure. “FDA approved” on a cat-litter bag, where FDA does not approve cat litter at all. Each of these is a quiet signal the supplier is selling against a checklist they have not earned.

Bottom line

A buyable private-label cat-litter program produces fourteen specific documents and numbers before a single bag is printed. The supplier either delivers them on a proforma invoice within one business day of the inquiry, or they spend three weeks reverse-engineering them out of a competitor's spec sheet. The first response tells you which kind of partner you are looking at.

At RootPurr we publish the spec because the documents already exist on every shipment we send. If you are evaluating two or three suppliers in parallel, run the same fourteen questions across all of them and compare the answers side by side. The variance will be revealing. Start the conversation on the private-label inquiry form and we respond inside one business day, M–F.
