The Contract Manufacturing Agreement
A proper contract manufacturing agreement covers:
1. Scope of work: What the factory makes, what you provide, what’s included in the unit price
2. Tooling ownership: Who owns the molds, where they’re stored, maintenance responsibility
3. Quality standards: AQL levels, defect definitions, inspection rights
4. Payment terms: Deposit, progress payments, balance
5. Intellectual property: NDA, non-compete, design ownership
6. Delivery: Lead times, penalty clauses, force majeure
7. Warranty: Defect rate, return handling, compensation
Gainer’s standard payment terms: 30% T/T with PO, 70% T/T before shipment. For repeat orders, 30% T/T deposit, 70% against copy of B/L (bill of lading).
Quality Control Architecture
A factory producing 250,000+ units monthly needs systematic QC. Gainer’s four-tier system:
IQC (Incoming Quality Control): Every material batch is checked. Plastic resin: Melt Flow Index. Steel: XRF composition. Battery cells: capacity and internal resistance (sample basis). Non-conforming lots are returned to supplier.
IPQC (In-Process Quality Control): QC inspectors at each production station. Assembly torque verification. Solder joint inspection (AOI on PCB lines). Motor current draw check. Random sampling at 2-hour intervals.
FQC (Final Quality Control): 100% function test on every unit. Motor start/stop, all speed settings, abnormal noise detection, accessory fit. AQL 2.5 sampling for cosmetic defects.
OQC (Outgoing Quality Control): Pre-shipment inspection per ANSI/ASQ Z1.4, Level II. AQL 2.5 for major defects, AQL 4.0 for minor defects.
BSCI and Social Compliance
European retailers (MediaMarkt, Carrefour, Auchan, Lidl, Aldi) require BSCI or equivalent social compliance audits. Gainer is BSCI-certified, which covers:
– No forced labor, no child labor
– Working hours within legal limits
– Minimum wage compliance
– Health and safety (fire exits, PPE, first aid)
– Freedom of association
BSCI certification is renewed every 2 years with an on-site audit by an approved third party (SGS, Bureau Veritas, TÜV, Intertek).
Value-Added Services
Gainer bundles three free services that reduce the time and cost of launching a branded product:
1. Free logo design: Vector artwork (AI/EPS) in multiple colorways, ready for pad printing, laser engraving, or IML (in-mold labeling)
2. Free packaging design: Color box layout with die-cut lines, barcode placement, and regulatory markings. CMYK print-ready files.
3. Free product photography: White-background hero shots and lifestyle photos. Suitable for Amazon listings, catalogs, and websites.
These services are included in the OEM/ODM pricing — not billed as separate line items.
FAQ
Q: What’s the difference between OEM, ODM, and contract manufacturing?
A: OEM: you design, factory builds. ODM: factory designs, you customize. CM: you provide everything, factory provides labor and facilities. Gainer offers OEM and ODM.
Q: How much tooling investment is needed for a new kitchen appliance?
A: $8,000-15,000 for a hand blender, $15,000-25,000 for a stand mixer. ODM reduces tooling cost because the factory already owns the platform molds. Gainer’s ODM route can reduce tooling to $2,000-5,000 for custom housing only. We explore this further in Immersion Blender ODM Factory.
Q: What are Gainer’s payment terms?
A: 30% T/T deposit with purchase order, 70% balance before shipment. For established repeat customers: 30% T/T deposit, 70% against copy of bill of lading.
Q: Does Gainer have BSCI certification?
A: Yes. BSCI certification is valid for 2 years. The most recent audit was conducted by an Amfori-approved third party. The BSCI report is available for review by qualified buyers.
Q: What kitchen appliances does Gainer manufacture?
A: Hand blenders (corded and cordless), meat grinders (home and commercial), stand mixers, cordless hand mixers, cordless choppers, and portable blenders. The factory runs 6 production lines across 9,000 square meters.

Production Line Integration
Contract manufacturing at Gainer works because the factory’s 6 production lines are designed for mixed-product output. A contract manufacturing order of 3,000 hand blenders slots into the production schedule without disrupting existing runs:
– Line 1-2: Hand blenders (corded and cordless). Dedicated to this product category, so your order runs on lines with experienced operators and optimized workflows.
– Line changeover time: 2-4 hours for color changes (purge injection molding machines, change packaging). 1-2 days for product changeover (different model, different accessories).
– Production scheduling: Gainer’s ERP system schedules production 4-6 weeks in advance. Your order is confirmed with a production slot when the PO is accepted.
The 250,000+ units/month capacity means a 3,000-unit order is a 3-day production run. The factory doesn’t need to clear the schedule for weeks — your order runs alongside other customers’ orders on the same line.
Supply Chain Management
A contract manufacturer manages the supply chain for components. Gainer’s supply chain covers:
– Motor components: Stator laminations, rotor shafts, commutators, carbon brushes, bearings — sourced from 8 qualified suppliers, with backup suppliers qualified for critical components.
– Plastic resin: ABS (PA-757), PBT+GF, PP, TPE — sourced from LG Chem, Chi Mei, and Sinopec distributors. Minimum 3-month inventory of standard resins.
– Steel: 304 SS (shafts, blades), 420J2 SS (blades, die plates) — sourced from Baosteel and TISCO distributors. XRF verification at incoming QC.
– Battery cells: Samsung INR18650-25R, LG INR18650-M26 — sourced through authorized distributors. Each batch is tested for capacity and internal resistance.
– PCBs: Designed in-house, fabricated by Shenzhen-based PCB suppliers, assembled on Gainer’s SMT line. For more, read Hand Blender Private Label Manufacturer.
Supplier qualification requires: ISO 9001 certification, on-site audit by Gainer’s purchasing team, 3-batch trial with 100% inspection, and annual re-audit.
The Financial Model
Contract manufacturing is a capital-intensive business. Gainer’s financial model:
– Factory investment: 9,000 square meters, 6 production lines, injection molding machines, die-casting machines, SMT line, QC lab. Estimated capital investment: $5-8 million.
– Working capital: 30% T/T deposit covers raw material purchases. The 70% balance before shipment means the factory carries minimal accounts receivable risk.
– Tooling: Customer-funded tooling is stored and maintained by Gainer. The factory does not charge storage fees during the active relationship.
– R&D: The 77+ patents represent ongoing R&D investment in motor design, battery systems, and mechanical innovations. Related: Kitchen Appliance Sourcing Agent vs Direct Factory.
Risk Management
Contract manufacturing relationships face risks that a good agreement anticipates:
– Raw material price fluctuation: ABS resin prices can swing 20-30% in a year. Gainer’s quotations are valid for 90 days. Longer-term contracts can include a raw material adjustment clause.
– Exchange rate fluctuation: FOB prices are quoted in USD. The RMB/USD exchange rate affects the factory’s profitability. Gainer manages this through financial hedging, not by adjusting prices mid-contract.
– IP protection: NDA is standard. Gainer’s 77+ patents protect the factory’s designs, and customer designs are protected by contract. The factory does not produce customer-owned designs for other buyers.
– Quality disputes: Defined in the quality agreement. Gainer’s standard: defects below 1% are considered acceptable. Above 1%, the factory provides replacement units or credit. Above 3%, the factory covers the cost of re-inspection and rework. See also: Best Kitchen Appliance OEM Manufacturers Shenzhen.
