Outsourcing your product packaging to a contract packager sounds straightforward—until you're staring at a 15-page agreement with terms you don't fully understand. Getting the contract right from the start protects your brand, timeline, and bottom line.
What You're Actually Buying
Contract packaging isn't a one-size-fits-all service. You need to nail down exactly what the packager will do: Are they assembling pre-made components into your finished product? Applying labels and inserts? Performing quality checks? Running secondary operations like shrink-wrapping or case packing? Get this in writing as a detailed scope of work, line by line. Vague language like "standard packaging services" creates disputes later when you expect something different than what arrives.
Volume Commitments and Minimums
Most co-packers require minimum order quantities (MOQs), typically ranging from 5,000 to 50,000 units depending on complexity and the packager's production line setup. Your contract should specify whether this minimum applies per production run, per month, or per year. You also need to know the penalty if you fall short—some packagers charge a setup fee regardless of volume, while others build per-unit costs that increase at lower volumes. Ask for a tiered pricing structure if you plan to grow: rates that drop at 25,000 units, again at 50,000, and higher. This incentivizes both parties and gives you cost clarity as you scale.
Lead Times and Production Schedules
Contract packaging isn't instantaneous. Standard lead times range from 3 to 8 weeks for routine jobs, but custom label printing or complex assembly can stretch to 12+ weeks. Your contract should specify the exact lead time from order placement to delivery, including any buffer time built in for quality holds. Include language around what constitutes a delay and what happens if the packager misses the deadline—does your payment get adjusted? Do they ship partial orders on time? Seasonal spikes can also affect availability, so clarify peak periods upfront and confirm your packager can accommodate your anticipated volume during those windows.
Quality Standards and Inspection
Define acceptable quality metrics in the contract: defect rates (typically 0.5% to 2% depending on your product), labeling accuracy, packaging integrity checks, and documentation. Ask whether the packager performs in-line inspection, end-of-line sampling, or both. You'll want the right to inspect batches before shipment—some contracts allow you to audit on-site or require the packager to send sample units for your approval. Include specific steps for handling rejected batches: Will they be reworked at no charge? Scrapped? Returned to you? Clarify who pays for both quality control and rework.
Liability, Insurance, and Protection
Your packager must carry product liability and property damage insurance. Request they list you as an additional insured party. Have them specify coverage limits (typically $1–$2 million minimum for mid-sized operations). The contract should also address intellectual property: your brand materials, formulations, and customer lists are confidential and must be returned or destroyed when the relationship ends. Include a non-compete clause prohibiting the packager from packaging competing products for a set period (12–24 months is standard).
Pricing and Payment Terms
Get itemized pricing: per-unit costs for packaging, labor, quality control, and any special handling fees. Don't just look at headline per-unit rates—ask about setup fees (usually $500–$2,000 per run), storage fees if they warehouse your materials, and fees for rush orders or design changes. Most co-packers work on 30-day net terms; confirm this in writing along with what triggers invoicing (shipment date, production completion, or payment milestones).
Termination and Exit Strategy
Include termination clauses that protect both sides. Specify notice periods (typically 30–90 days) and what happens to in-progress inventory or stored materials. Determine who owns work-in-progress and whether you can retrieve it. If either party wants to end the relationship, know the financial obligations upfront.
Mercoly makes it easier to compare contract packaging providers side-by-side so you can review their terms, capabilities, and track records before signing anything.
Frequently Asked Questions
Q: How do I protect my product formula or proprietary design when working with a co-packer? Request a non-disclosure agreement (NDA) separate from the main packaging contract, specify that your materials and data cannot be shared with other customers, and clarify what happens to your materials if the relationship ends—usually destruction or return within 30 days.
Q: What happens if my packager suddenly raises prices mid-contract? Your contract should lock pricing for a defined term (usually 12 months); price increases typically require 60–90 days' written notice and apply only to new orders, not in-flight work.
Q: Can I switch packagers quickly if I'm unhappy with their quality? Most contracts require 30–90 days' notice and completion of current orders; ensure your contract allows you to retrieve stored inventory and materials immediately rather than fighting over them.
