FDA Food Ingredient Rule Impacts Packaging Industry Compliance

How to Audit Your Current Offshore Tooling Program Before Your Next Compliance Review

If your food-contact packaging program currently sources tooling from China, run this audit before your next regulatory review. This checklist reflects what our team runs when onboarding a new offshore program.

1. Pull every active tool in your food-contact program. Note the mold maker, the tool steel grade, and the cavity coating or surface treatment specified in the original purchase order.
2. Request lot-level resin certifications for the last three production runs from your molder. If they cannot provide these, your compliance file has a gap that predates the new rule.
3. Request the product name and SDS for every mold release agent used during T1, T2, and current production. Cross-check each against its food-contact approval status.
4. Request cavity coating composition documentation from your mold maker. If the tool was built offshore, contact the original Chinese supplier directly. Do not assume your US molder has this on file.
5. Confirm with your resin supplier that the specific grades they ship to your molder are FDA 21 CFR-compliant grades, not standard commercial grades with similar base specifications.
6. Review any processing aids or additives your molder introduces at the press. Require a product name and SDS for each one.
7. Identify any material inputs that previously relied on self-affirmation of GRAS status. Those are your highest-exposure items under the new notification rule.

This audit typically takes two to four weeks to complete when an offshore mold maker is involved, compared to three to five business days for a well-organized domestic program. If a compliance review is within sixty days, start immediately.

What to Require From Your Mold Maker Before You Pull the First Production Shot

For new tooling programs, build these requirements into your purchase order before the tool is cut. Attempting to collect this documentation retroactively from an offshore supplier adds four to eight weeks to your qualification timeline and rarely produces a complete package.

Require the following in your RFQ and PO for any food-contact tool built offshore:

• Written confirmation of cavity steel grade and the mill certificate. For food-contact tools, 420SS is standard for corrosion-resistant applications, H13 for high-temperature applications, and P20 for standard food-contact work.
• Cavity coating composition documentation, including the specific product name and manufacturer for any post-machining surface treatment
• A commitment to use only food-contact-approved mold release agents, with product names and SDS sheets provided before T1
• Signed confirmation that no non-food-contact lubricants will be used on components that contact the part surface
• Agreement that any cavity repair or rework during the tool’s production life will be documented and disclosed to the buyer

These requirements add one to two weeks to the supplier qualification process upfront. They prevent four to eight weeks of retroactive documentation work later, and they protect your program against compliance exposure that can halt production without warning.

If your current offshore tooling program does not have these provisions written into supplier agreements, correct that before placing your next tool order. Our injection molding consulting practice structures offshore RFQs with food-contact documentation requirements as a standard deliverable. Start with a program audit if you are unsure where your gaps are.

Frequently Asked Questions

What plastics are FDA approved for food contact injection molding?

The most common FDA-approved resins for food-contact injection molding are polypropylene and polyethylene (21 CFR 177.1520), PET (21 CFR 177.1630), and polystyrene (21 CFR 177.1640). Approval is grade-specific and lot-specific. A resin family being generally listed does not mean every grade or every production lot from every supplier meets food-contact requirements. Lot-level certificates must confirm the specific shipment’s compliance with the applicable CFR section.

Does my offshore mold supplier in China need to meet FDA food contact standards?

Your Chinese mold supplier does not need FDA certification, but you do. The compliance obligation sits with the US manufacturer placing food-contact parts into commerce. That means you are responsible for ensuring that every material input your offshore supplier uses, including mold release agents, cavity coatings, and lubricants, is documented and approved for food contact. The mold maker builds the tool. You own the compliance record.

How does the new GRAS notification rule affect my injection-molded packaging program?

The new rule replaces the self-affirmation pathway with a formal FDA notification requirement for food ingredients and contact substances. Any additive in your resin compound, mold release agent, or cavity coating that previously relied on self-affirmed GRAS status now requires a formal notification on file with FDA. If your material suppliers cannot confirm that their food-contact substances have active notifications, those inputs carry elevated regulatory exposure for your program.

What documentation should I require from a mold maker for food-contact parts?

Require resin lot certifications tied to the specific FDA 21 CFR section, SDS sheets for all mold release agents with food-contact approval documented, cavity coating composition disclosure, lubricant product names and food-contact status, and written confirmation that no non-approved processing aids will be used during T1 or production. Build these requirements into your purchase order before the tool is cut, not after.

Can I still source food-contact packaging molds from China and stay compliant?

Yes, but the documentation obligation stays with you. Chinese mold makers build accurate, cost-effective tooling. They do not typically maintain the compliance documentation a US food-contact program requires without contractual direction. Specify those requirements in your RFQ and purchase order, audit them at T1 and T2, and maintain the compliance file on your side. Our team structures offshore food-contact programs to meet these requirements without adding significant cost to the tooling budget.

What is the difference between FDA 21 CFR compliance and a GRAS notification?

FDA 21 CFR compliance refers to a specific resin or additive meeting the requirements of a designated CFR section, confirming it is approved for food contact at specified use conditions. A GRAS notification is a separate process where a manufacturer submits evidence to FDA that a substance is safe for its intended use. Under the new rule, substances that were previously self-affirmed as GRAS now require a formal notification filing rather than an internal determination that stays in the company’s records.
