Pet food–specific sourcing guide: raw materials, price tiers, import standards, and supplier qualification for global pet food manufacturers.

Why This Guide Exists

Potato flakes in human food applications are manufactured from premium whole potatoes (typically Atlantic, Shepody, or Russet Burbank varieties) under strict food-grade standards. Pet food potato flakes are a different product category altogether, and understanding this distinction is the first step to sourcing correctly.

The global pet food market exceeded $120 billion in 2026, with the grain-free and natural segment growing at 15%+ year-over-year. For pet food manufacturers, potato flakes offer a cost-effective carbohydrate source — but at price points that are typically 50-70% below food-grade flakes. This price gap exists because the raw materials are fundamentally different.

Raw Materials: What Pet Food Potato Flakes Are Actually Made From

There are two primary raw material sources for pet food potato flakes:

1️⃣ 落地粉 (Floor Powder)

The potato flakes that fall, scatter, or spill during the food-grade production process — from conveyor belts, packaging lines, sieving stations, and other processing points. This material is collected from the production floor, re-screened, and packaged as pet food grade.

Characteristics:

• Purity: 95-99% potato flake material (may contain trace floor debris)
• Particle size: Mixed — typically finer than food-grade due to breakage
• Moisture: Slightly higher than food-grade (8-12%)
• Price: Lowest tier
• Supply: Limited by food-grade production volume — not independently scalable

2️⃣ 超标粉 (Substandard Powder)

Potato flakes from food-grade production that fail one or more specification parameters (moisture, particle size, color, microbiological count, or other COA indicators) beyond the acceptable tolerance for human food, but still safe and functional for animal feed.

Characteristics:

• Purity: 100% potato flake material
• Failed parameter varies by batch — could be color deviation, moisture spike, or particle size out-of-spec
• Price: Low to mid-tier (depending on which parameter failed and by how much)
• Each batch requires individual evaluation against the buyer’s import standards

Specialty: Blended / Rework Material

Some suppliers blend floor powder with substandard material or rehydrate and re-dry production scrap. Quality and consistency vary significantly. Buyers should request detailed COA data and verify through third-party testing.

Price Tiers and What They Mean

Important: The buyer must provide the applicable import standards from their destination country. The supplier evaluates whether their material can meet those standards, not the other way around.

Pet Food Standards: Buyer Provides the Target

Unlike food-grade potato flakes which must meet CODEX or national food standards, pet food potato flakes operate on a buyer-specified standard model. This means:

1. The buyer provides the specification sheet (target values for moisture, protein, ash, aflatoxins, pathogens, etc.)
2. The supplier confirms whether their current batch can meet those specifications
3. The COA is issued against the buyer’s target, not a universal pet food standard
4. Third-party testing at destination is strongly recommended for every shipment

Typical Specifications Buyers Request for Pet Food Potato Flakes

Always confirm your destination country’s specific feed material regulations before placing an order.

Regulatory Compliance: Market-Specific Requirements

🇺🇸 US Market

• AAFCO: Potato flakes must meet the AAFCO ingredient definition for use in labeled pet food. Confirm the specific AAFCO number with your regulatory team.
• FSMA: Suppliers must comply with FSMA Preventive Controls for Animal Food (21 CFR Part 507). However, many Chinese pet food suppliers do not have FSMA compliance programs — verify before ordering.
• FSVP: The US importer bears responsibility for Foreign Supplier Verification. Even if the supplier cannot provide FSMA documentation, the importer must verify safety through alternative means.
• USDA APHIS: Phytosanitary certificate required. Additional import permits may apply for certain potato-derived products.

🇪🇺 EU Market

• Reg 767/2009: Potato flakes for animal feed are regulated under the EU feed materials catalogue.
• Contaminant limits per Directive 2002/32/EC: Arsenic <2 ppm, lead <10 ppm, aflatoxin B1 <20 ppb.
• Supplier registration: Exporters should register with EU RASFF (Rapid Alert System for Food and Feed).
• FAMI-QS certification: Strongly preferred — but rare among Chinese pet food potato flake suppliers.

Supplier Qualification Checklist

Step 1: Define Your Standards

Before contacting any supplier, prepare a written specification sheet covering all parameters your destination country requires. Without this, the supplier cannot determine if their material is suitable.

Step 2: Request Batch-Specific COA

Not all batches from the same supplier are the same. Floor powder and substandard material vary by production run. Request COAs from 3 different batches to assess variability.

Step 3: Verify Raw Material Source

Ask the supplier: “Is this batch floor powder, substandard food-grade, or blended?” A transparent supplier will tell you. A non-transparent supplier may label everything as “pet food grade” without distinguishing the source.

Step 4: Third-Party Testing

For initial orders, arrange third-party testing (SGS, Eurofins, Intertek) at origin or destination to verify the supplier’s COA.

Step 5: Confirm Export Readiness

Step 6: Sample Testing

Request a 1-5kg sample and test in your own production line. Pay attention to:

• Rehydration behavior in cold water (for raw/cold-process formulations)
• Particle size distribution and fines content
• Any foreign material (with floor powder, this risk is higher)
