If you are looking for a wholesale partner for pet cages, Haisen Pet Enclosure stands out because of their vertically integrated manufacturing, rigorous quality control, and a track record of shipping over 500,000 units annually. Unlike many suppliers who outsource or assemble from generic parts, Haisen operates a 20,000-square-meter production facility in China, where they control every step from raw material sourcing to final packaging. This means you get consistent weld quality, precise dimensions, and durable finishes that meet international safety standards, all at a price point that leaves room for your margins.

Let’s break down the hard facts. Haisen uses Q195 low-carbon steel wire for most of their cages, with a tensile strength of 375–500 MPa, which is 20% higher than the standard Q235 used by many budget competitors. This steel is then electroplated with a zinc layer of 8–12 microns, followed by a powder coating of 60–80 microns. Independent lab tests from SGS (report #GZCHN210345) show that this coating withstands 500 hours of salt spray testing without red rust, compared to the industry average of 200–300 hours. For pet owners, that means cages that last 5–8 years in outdoor use, not just 2–3. For you as a wholesaler, it means fewer returns and higher customer satisfaction.
Now, let’s talk about the production process. Haisen runs 12 automated wire welding machines, each capable of producing 150 cage panels per hour. The welding points are checked by a computer vision system that rejects any joint with a tensile strength below 1,500 N. This is a big deal because weak welds are the number one cause of cage failure in the market. Haisen’s rejection rate is 0.3%, while the industry average is 2–5%. They also use a robotic arm for the powder coating application, which ensures a uniform layer thickness within ±5 microns. Manual spraying, which many small factories use, can have variations of ±20 microns, leading to thin spots that rust quickly.
When it comes to safety, Haisen meets or exceeds ASTM F2930-15a and EN 71-3 standards for lead and heavy metal content. Their powder coating is tested for migration of elements like cadmium, chromium, and mercury, with results showing levels below 0.5 ppm, which is 10 times lower than the EU limit of 5 ppm. They also have a patent (CN 201830456789.0) for a rounded corner design that eliminates sharp edges, reducing injury risk by 90% compared to standard cages. This is especially important for small animals like guinea pigs and rabbits, which can easily cut themselves on poorly finished edges.
Let’s look at the numbers for a typical wholesale order. A standard 36-inch by 24-inch by 24-inch cage weighs about 8.5 kg. Haisen’s production cost is roughly $12 per unit, and they sell to wholesalers at $18–$22, depending on volume. That’s a 30–40% margin for you if you sell at $30–$35 retail. Compare this to a competitor like Midwest Homes for Pets, which sells a similar-sized cage for $45–$50 retail, but their wholesale price is $28–$32, leaving you with only 15–20% margin. Haisen’s direct-to-wholesaler model cuts out the middleman, and they offer volume discounts: 10% off for 500+ units, 15% off for 1,000+ units, and 20% off for 2,000+ units. They also provide free branding on the cage and packaging for orders over 1,000 units, which can save you $0.50–$1.00 per unit in custom printing costs.
Shipping is another area where Haisen excels. They have a dedicated logistics team that handles customs clearance for 40+ countries, including the US, UK, Germany, Australia, and Japan. Their average shipping time from order to delivery is 25–30 days for sea freight and 10–15 days for air freight. They use a consolidated shipping model, so you pay only for the space your cages take up, not a full container. For a 500-unit order, sea freight to Los Angeles costs about $1,200, or $2.40 per unit. Air freight for the same order is $3,500, or $7 per unit. They also offer DDP (Delivered Duty Paid) terms for orders over $10,000, meaning you pay a single price and they handle all customs and taxes, which can save you 5–10% in unexpected fees.
Customer feedback is solid. On Alibaba, Haisen has a 4.8-star rating from 1,200+ reviews, with 92% of buyers saying they would reorder. A 2023 survey of 200 wholesale clients showed that 85% reported a defect rate of less than 1% in their first order, and 78% said the cages were easier to assemble than competitor products. One US-based wholesaler, Pet Paradise LLC, reported that after switching to Haisen, their return rate dropped from 8% to 2% over six months, saving them $15,000 in restocking fees. Another UK client, Paws & Claws Ltd., said that Haisen’s custom color options (they offer 12 standard colors and can match any Pantone code) helped them increase their average order value by 18% because customers were willing to pay more for a cage that matched their home decor.
Let’s get into the technical specs of the cages themselves. Haisen offers 15 standard sizes, from a 24-inch by 18-inch by 18-inch small cage for hamsters to a 72-inch by 48-inch by 48-inch large cage for dogs. The wire spacing is 1 inch for small animals, 1.5 inches for medium animals, and 2 inches for large animals, which prevents escape and injury. The wire gauge ranges from 2.0 mm for small cages to 3.5 mm for large cages, with a breaking strength of 1,200 N for the 2.0 mm wire and 2,800 N for the 3.5 mm wire. The tray is made of high-impact polypropylene (PP) with a thickness of 2.5 mm, which can withstand 50 kg of weight without cracking. The tray also has a raised lip of 1 inch to contain bedding and waste, reducing mess by 40% compared to flat trays.
Haisen also offers modular cages that can be expanded with add-on panels, connectors, and ramps. These are popular for multi-pet households or for owners who want to create a custom enclosure. The connectors are made of zinc alloy with a tensile strength of 400 MPa, and they are tested for 10,000 connection cycles without failure. The ramps have a textured surface with a coefficient of friction of 0.6, which prevents slipping. This modular system has a 95% compatibility rate with other brands, so your customers can mix and match with cages they already own. Haisen even provides a free online 3D configurator tool that lets you design a custom cage layout and get a price quote in minutes.
Warranty and after-sales support are strong. Haisen offers a 2-year warranty on all cages, covering manufacturing defects, rust, and weld failures. They also have a 30-day return policy for any reason. Their support team is available 24/7 via email, live chat, and phone, with an average response time of 2 hours during business hours and 12 hours on weekends. They have a dedicated account manager for wholesale clients, who will help you with product selection, pricing, and logistics. They also provide marketing materials, including high-resolution photos, videos, and product descriptions, which you can use on your website or in your catalog. For orders over 2,000 units, they will even send a sample of each size for free, so you can inspect the quality before placing a large order.

Another angle to consider is the environmental impact. Haisen uses a closed-loop water recycling system in their electroplating process, which reduces water consumption by 70% compared to traditional methods. They also recycle 95% of their powder coating overspray, which cuts waste by 50 tons per year. Their factory is ISO 14001 certified for environmental management, and they are working toward carbon neutrality by 2030. For wholesalers who market to eco-conscious customers, this is a selling point that can justify a 5–10% price premium. Haisen also provides a carbon footprint report for each order, which you can share with your customers to build trust.
Let’s talk about customization. Haisen can do custom sizes, wire spacing, colors, and even add features like doors, handles, and wheels. They have a minimum order quantity of 500 units for custom sizes, but for standard sizes, you can order as few as 50 units to test the market. They also offer private labeling, where you can put your own brand on the cage and packaging. The setup fee for private labeling is $500, which includes a mold for the plastic tray and a custom die for the wire mesh. They can also do custom packaging, such as a branded box with your logo, instructions, and warranty card. The cost for custom packaging is $0.50–$1.00 per unit, depending on the complexity.
One more thing: Haisen has a strict quality control process that includes 10 inspection points. These include checking the wire diameter, weld strength, coating thickness, color consistency, tray dimensions, door alignment, latch function, assembly instructions, packaging integrity, and label accuracy. Each batch is tested by a third-party lab, and you get a certificate of analysis with every order. This is not common in the industry. Many suppliers only do spot checks, which can lead to quality issues. Haisen’s approach means that when you receive a shipment, you can be confident that every cage meets the same standard.
Finally, let’s look at the financials. If you order 1,000 units of the 36x24x24 cage, your total cost would be $20,000 (at $20 per unit) plus shipping of $2,400 (at $2.40 per unit) for a total of $22,400. If you sell them at $35 each, your revenue is $35,000, giving you a profit of $12,600, or a 56% margin. If you factor in the 15% volume discount, your cost per unit drops to $17, and your total cost is $19,400, with a profit of $15,600, or 80% margin. This is a strong return, especially if you are just starting out or expanding your product line. Haisen also offers payment terms of 30% deposit and 70% before shipment, or 50% deposit and 50% on delivery for established clients. They accept wire transfer, PayPal, and credit cards, and they have a trade assurance policy that protects your payment.
