Contract packaging and co-packing services handle everything from filling and sealing to labeling and shipping—letting you focus on product development and sales instead of logistics headaches. Whether you're scaling a startup or looking to cut packaging overhead, understanding what's actually included in these services helps you find the right partner and budget accordingly. Here's what you need to know before signing on.
Core Packaging Services
Most contract packagers handle the fundamental operations that turn bulk product into market-ready units. This includes filling containers (bottles, jars, tubes, pouches), sealing or capping, and applying labels or tamper-evident features. Many also manage secondary packaging—boxing individual units, creating multipacks, or assembling gift sets.
The scope depends on your product type and volume. A cosmetics co-packer handles different equipment than a food or supplement packager, and minimum order quantities typically range from 5,000 to 50,000 units depending on the facility and your complexity. Always ask about machine changeover times and whether they charge fees for custom setups.
Equipment and Technology
Contract packagers invest in specialized machinery for specific industries. You'll find filling lines for liquids, powder dosing systems, capping equipment, and labeling stations. Many modern facilities use automated systems that reduce labor costs and improve consistency—expect to see faster turnaround on larger runs.
Ask potential partners about their equipment capabilities, uptime rates, and whether they can handle variable volumes. Some offer flexible packaging options (bottles vs. pouches, for example) on the same production line, while others specialize in one format. Request a facility tour or detailed equipment list before committing.
Quality Control and Compliance
This is non-negotiable. Reputable packagers maintain QC protocols including weight checks, seal integrity testing, and visual inspections. They also hold certifications relevant to your industry—FDA registration for food and supplements, cGMP for pharmaceuticals, or ISO standards for various sectors.
Clarify their testing procedures upfront. Do they perform microbial testing? How often? What's their defect tolerance rate? Expect documentation of all QC activities and traceability systems that track batch numbers and production dates. If you're in a regulated industry, confirm their audit history and insurance coverage.
Warehousing and Fulfillment
Many contract packagers offer integrated warehousing, storing your bulk ingredients, finished goods, or both. This eliminates extra shipping steps and reduces your storage overhead. Some facilities include basic fulfillment services—order picking, kitting, and direct-to-customer shipping.
Costs vary: warehousing typically runs $0.50–$2.00 per pallet per month depending on location and climate control needs. Fulfillment fees add $1–$5 per order. Make sure your agreement specifies inventory management, rotation policies (FIFO), and what happens if product expires before you move it.
Turnaround Times and Minimums
Standard lead times range from 2 to 6 weeks depending on product complexity, packaging type, and current facility capacity. Rush services exist but usually cost 25–50% more. Some packagers offer just-in-time capabilities if you have consistent demand patterns.
Minimum order quantities vary widely:
- Simple fill-and-cap operations: 5,000–10,000 units
- Custom label design and setup: 15,000–25,000 units
- Complex assembly or multi-component kits: 25,000+ units
- Smaller minimums available for premium rates
Always negotiate minimums based on your volume projections; some facilities offer tiered pricing that improves margins at higher volumes.
Pricing Factors
Contract packaging isn't a simple per-unit cost. You'll typically pay a setup or changeover fee ($500–$2,000), a per-unit packaging cost (usually $0.10–$1.00 depending on complexity), and potentially materials markup, storage, and handling fees. Get itemized quotes and compare total landed cost across three to five providers.

Frequently Asked Questions
Q: What happens if I need to change my packaging design mid-contract? A: Most packagers charge a setup fee for any design changes, and you may face delays if they're operating at capacity. Review your contract's change-order policy upfront to avoid surprises.
Q: Can a contract packager source materials like bottles or labels, or do I provide everything? A: Many offer materials sourcing as an add-on service with markup, while others require you to supply everything. Discuss this before signing—some facilities have preferred vendors that offer volume discounts you can leverage.
Q: How do I verify a packager's quality standards before hiring? A: Request copies of recent QC reports, audit certificates, and references from similar clients. Visit the facility if possible, and insist on a trial run of 1,000–5,000 units before your full order.
