Four Types of Genuine, Compliant Traceability Chains for Food Packaging Inks—How Printers Can Provide Documentation When Customers Request an MSDS

Food packaging printers are asked by customers at least 5-8 times a year: “Do you have the MSDS for the inks you use?”, “Can you provide an ink migration report?”, and “Can products from the same batch be traced?”. The ones asking most frequently are not the food manufacturers themselves, but their foreign trade agents, e-commerce fulfillment warehouses, and cross-border logistics providers. When printers receive such requests, their first response is often to ask the ink supplier to send a document. However, what customers actually need is not a single document, but a chain of 4 types of documents. Below is the actual pathway still in use in 2026.

Why Customers Do Not Just Need an MSDS

Since 2024, the European Union's EU 1935/2004, the U.S. FDA's 21 CFR 174-179, and China's GB 4806.7-2023 have all introduced requirements for “end-to-end compliance verification” for food-contact inks. A single MSDS is no longer sufficient. When customers—particularly those in Europe and North America and cross-border e-commerce customers—conduct product compliance reviews, they need four types of documents that corroborate one another: the raw material MSDS, migration test report, supplier declaration, and batch traceability record. These four types of documents come from four different parties: the ink manufacturer, third-party testing laboratory, raw material supplier, and printing plant.

Real Case of a Botched Delivery: In September 2025, one of our clients producing German food packaging orders was asked by the German importer to provide a chain of compliance documentation for the ink. The printing plant provided only the ink supplier's MSDS, and the German importer rejected it 3 times. The reason was that the MSDS covered only the safety of the ink formulation, but did not include migration data for the specific food type. As a result, it took us 11 days to complete 4 categories of documentation before we could deliver the order.

Category 1: Raw Material MSDS (Material Safety Data Sheet)

An MSDS is a Chemical Safety Data Sheet provided by the ink supplier and covers 16 sections: composition, hazards, first aid, firefighting, spill response, handling, storage, exposure control, personal protection, physical and chemical properties, stability, toxicity, ecological effects, disposal, transport, and regulatory information.What the printing plant needs to retain is not a single MSDS, but at least one current version for each ink SKU every year.

In actual operations, printing plants often encounter three pitfalls:

1. Chinese Version vs. English Version——EU customers require the English MSDS (compliant with all 16 provisions of EU 2020/878), US customers require the US-standard MSDS (compliant with OSHA HCS 2024), and Japanese customers require the Japanese version (JIS Z 7253:2019). If the printing plant only has the Chinese version, customers will immediately reject it.
2. Version Currency——After ink formulation adjustments, the MSDS version number must also be updated. The printing plant must obtain the latest version from its supplier at least once a year; customers will refuse to accept versions more than 12 months old.
3. Scope of Coverage——The MSDS covers only the ink itself, not the curing or migration behavior of the ink on paper. If customers rely solely on the MSDS, they may mistakenly assume compliance; in reality, a migration amount report is also required as supporting documentation.

Category II: Migration Test Report (Specific Food Type + Specific Ink)

Migration testing is a core compliance requirement for food-contact packaging. The printing plant must engage a third-party testing organization (such as SGS, Intertek, or CTI) to issue a report covering the following 4 scenarios:

1. Food simulant testing (distilled water / 3% acetic acid / 10% ethanol / olive oil or an alternative solvent), with 1-4 selected according to the customer’s actual food type.
2. Test temperature and duration—based on the customer’s intended food-use conditions, such as 10 days at room temperature / 30 days refrigerated / 2 hours at 70℃ / 30 minutes at 100℃; each condition must be tested separately.
3. Specific substance testing—EU 1935/2004 focuses on four heavy metals, including lead, cadmium, mercury, and hexavalent chromium; US FDA 21 CFR 109 focuses on photoinitiators and residual benzene solvents; and China GB 4806.7 focuses on phthalates and aromatic amines.
4. Report validity period—test reports are typically valid for 2-3 years, but retesting is mandatory after any formulation change. The printing plant must establish a ledger of ink formulation changes.

Real-world data: In 2024-2025, we conducted migration testing for a food packaging customer. The average cost per SKU was 8000-15000 RMB, covering 4 food simulants, 4 heavy metals, and phthalate testing. The customer paid a separate testing fee for this item alone.

Category 3: Supplier Declaration (a compliance commitment issued by the ink manufacturer to the printing plant)

This is one of the most commonly omitted categories of documentation in China's food packaging compliance system. Ink manufacturers must clearly state 4 items in the declaration:

1. Formulation Compliance Declaration — All raw materials used in the ink comply with the permitted-substance lists of applicable regulations, including EU 1935/2004 / FDA 21 CFR 174-179 / GB 4806.7-2023.
2. Declaration of Absence of Harmful Substances — Free from 4 heavy metals, specified phthalates, specified aromatic amines, and specified photoinitiators (selected according to the customer’s target market).
3. Manufacturing Process Compliance Declaration — The ink manufacturing process conforms to the ISO 9001 + ISO 14001 management systems, and raw material sources are traceable.
4. Shelf-Life Declaration — The ink has a shelf life of ≥ 12 months from the date of manufacture when unopened.

The printing plant must proactively request the declaration from the ink supplier rather than wait until the customer asks for it. If the printing plant only requests it when the customer asks, it generally takes the supplier 5-10 working days to provide it. An excellent printing plant should explicitly require the supplier to provide the declaration with the goods when signing the ink purchase contract.

Category 4: Batch Traceability Form (production record issued by the printing plant itself)

This is the printer’s core internal compliance document, covering the entire production process of the printer’s own products. A complete batch traceability form must contain 8 items:

1. Order Number + Customer Name + Product Name + SKU—Basic customer information.
2. Production Date + Delivery Date + Quantity—Basic product status.
3. Ink SKU + Ink Batch Number + Ink Supplier + MSDS Version Number—Ink source.
4. Paper SKU + Paper Supplier + Paper Grammage + Paper Batch Number—Paper source.
5. Glue/Varnish/Lamination Adhesive SKU + Supplier + Batch Number—Auxiliary material source.
6. Press Number + Press Operator + Shift + Printing Parameters—Printing process.
7. Post-Pressing Process + Die-Cutting Plate Number + Foiling Plate Number + UV Lamp Tube Batch—Post-pressing process.
8. QC Inspector + Sampling Ratio + Inspection Results + Retained Sample Number—Quality records.

Real Failure Case: In June 2025, one of our customers producing labels for milk powder cans was selected for inspection by the market regulation authority and asked to provide batch traceability records from the previous 3 months. Although the printer had complete paper records at the time, its electronic ledger was missing, and the market regulation authority imposed a fine of 2 wan yuan. We later implemented an ERP system to digitize all batch records in real time.

4 Steps to Prepare When a Printing Customer Requests an MSDS

1. Day 1: Confirm the customer’s target market (EU / US / Japan / China / other). Regulatory requirements vary significantly between markets.
2. Days 2-3: Provide the customer with the list of 4 document categories (MSDS + migration volume report + supplier declaration + batch traceability sheet), and have the customer confirm whether any additional testing items are required.
3. Days 4-5: Internally compile the batch traceability sheet to ensure that the SKU, batch number, supplier, and MSDS version number of all raw materials used in the order can be matched.
4. Days 6-7: Package the 4 document categories as the “Food Packaging Compliance Chain Document Package” and deliver it to the customer, while also archiving it internally for reference.

Conclusion: A compliant supply chain is the printing plant’s core competitiveness

In the food packaging industry, compliance chains are not a service that ends once the printer completes production; they are capabilities that must be established from the first day an order is accepted. Printers that can provide a complete chain of 4 categories of documentation can quote 5-10% higher when bidding against competitors, because customers are not paying for printing fees; they are purchasing compliance assurance. Since 2023, we have accumulated 200+ compliance-chain document packages for food-sector clients, and the service workflow for each customer broadly follows the 4 steps described above. If your factory also wants to take on food packaging orders, the first step is to establish an ink traceability chain.
