Sourcing custom pet products from China? Choosing the right factory is critical to avoid delays, quality issues, and wasted costs. Whether you’re making pet toys, collars, or accessories, these 8 core audit points will help you evaluate factories from sampling to mass production, with practical tips for real-world sourcing.

1. Mold Development Capability
Why It Matters
Good mold development reduces design errors and speeds up sampling. Poor molds can lead to misshapen products (e.g., uneven pet bowls or misfitting collars).
How to Audit
- Ask for mold portfolio: Request photos of their existing molds for similar products (e.g., plush toy patterns or plastic pet feeder molds).
- Sample test: Order a prototype and check if details like logo embossing or stitching align with your design.
- Case: A US brand found a Dongguan factory with in-house mold designers who adjusted a dog harness buckle mold 3 times for free until it met safety standards.

2. Quality Control Process
Key Steps to Check
- Raw Material Testing: Do they test fabrics for AZO dyes (EU standard) or plastics for heavy metals (CPSC in the US)? Ask for material safety certificates (e.g., OEKO-TEX for textiles).
- In-Process Inspections: Look for IPQC (In-Process Quality Control) records—do they check stitching strength in toys or buckle durability in collars during production?
- Final Inspection: Do they use AQL (Acceptable Quality Limit) standards (e.g., AQL 2.5 for minor defects)? Request a sample inspection report.
Tip
Visit the factory (or ask for a video tour) to see QC workers in action—e.g., a Yiwu factory using metal detectors to scan pet toys for small parts.

3. Production Capacity & Lead Time
Questions to Ask
- Monthly Output: Can they handle your order size? A small factory may max out at 5,000 units/month, while larger ones do 50,000+.
- Lead Time Breakdown: How long for sampling (7–15 days is standard), mold making (10–20 days), and mass production (20–45 days for 5,000 units)?
- Case: A UK buyer chose a Zhejiang factory with 2 assembly lines, ensuring their 3,000-unit pet bed order was delivered 10 days earlier than a competitor with only 1 line.
4. Design Support & Communication
What to Look For
- Design Team: Do they have in-house designers who can adjust your sketches into technical drawings (e.g., converting a collar design into a 3D model)?
- Language Skills: At least one staff member should speak basic English to avoid miscommunication (e.g., “soft fabric” vs. “smooth fabric” in pet beds).
- Tool: Use platforms like Alibaba Trade Assurance for clear message history and document sharing.

5. Certifications & Compliance
Must-Have for Target Markets
Market | Key Certifications | Example Product |
---|---|---|
USA | ASTM F963 (toys), CPSC (children’s products) | Pet chew toys |
EU | EN 71 (safety), REACH (chemicals) | Pet clothing with prints |
Japan | ST 2016 (toys), JIS (textiles) | Plush pet mats |
Action
Ask for valid certification copies—check expiration dates and ensure they match your product category (e.g., a collar factory with only toy certifications may lack textile compliance).

6. Sample Making Process
4 Steps to Evaluate
- Sample Cost: Is it refundable on bulk orders? Most factories charge $50–$100 for custom samples, refundable when ordering 500+ units.
- Revisions: How many free revisions do they offer? A good factory allows 2–3 adjustments (e.g., fixing the logo position on a pet tag).
- Delivery Time: Can they send samples via DHL/FedEx in 3–7 days? Delayed samples often signal production inefficiencies.
- Case: A Canadian brand rejected 2 collar samples for color 偏差 (color deviation) but the factory corrected it quickly, earning their trust for a 2,000-unit order.
7. Packaging & Labeling Expertise
Key Considerations
- Custom Packaging: Do they offer design services for retail boxes (e.g., die-cut boxes for pet toys with window displays)?
- Label Compliance: Can they print required labels (e.g., “Made in China” for the US, or French/Spanish warnings for EU pet food containers)?
- Test: Request a sample package to check for barcode readability and label adhesion.
8. After-Sales Support
What to Ask
- Defect Handling: What’s their policy for faulty products (e.g., replacing 1% defective collars in a batch)?
- Reorder Lead Time: How fast can they handle repeat orders? A factory with organized molds may reduce lead time by 30%.
- Case: A 澳洲卖家 had 50 pet bowls with scratches; the factory replaced them within 7 days and improved their packaging for future orders.
Case Study: How a Brand Avoided a Factory Nightmare
A German pet brand audited 3 factories for custom dog harnesses:
- Factory A: No in-house molds, relied on third-party designers (delayed sampling by 2 weeks).
- Factory B: Lacked EU REACH certification for fabric dyes (failed compliance checks).
- Factory C: Passed all 8 points—had mold experts, strict QC, and ISO 9001 certification.
- Result: Factory C delivered 5,000 harnesses on time with 0.5% defect rate, becoming their long-term partner.

How to Start Your Factory Audit
