What are the regulations for food trays used in international shipping?

Understanding the Rules for Food Trays in Global Shipping

When you’re shipping food trays internationally, whether they’re full of product or empty for sale, you’re navigating a complex web of regulations designed to ensure safety, prevent contamination, and protect the environment. The rules aren’t governed by one single global law but are a patchwork of international standards, national import/export laws, and specific material requirements. The core principle is that any material that comes into contact with food must be safe and not transfer any harmful substances. This means the trays themselves, often a type of Disposable Takeaway Box, must meet strict criteria before they ever get near an airplane or cargo ship.

The Foundation: International Standards and Frameworks

At the highest level, organizations like the World Trade Organization (WTO) and the Codex Alimentarius Commission set the stage. The WTO’s Sanitary and Phytosanitary (SPS) Agreement dictates that any national regulations must be based on science. This prevents countries from creating arbitrary rules that act as trade barriers. For food safety, including packaging, the Codex Alimentarius provides global standards. While not legally binding themselves, Codex standards are the benchmark. For instance, Codex has general guidelines on how to assess the safety of food packaging materials, focusing on something called “migration limits.” This is the maximum amount of substance that can legally transfer from the packaging into the food. National authorities, like the FDA in the US or the EFSA in Europe, then use these guidelines to create their own, legally enforceable rules.

Material-Specific Regulations: The Devil is in the Details

The regulations you must follow depend almost entirely on what the food tray is made from. A plastic tray has a completely different set of rules than a wooden or aluminum one. This is where the highest density of specific data comes into play.

Plastic Trays (including PP, PET, PS): This is the most common category for disposable trays. Regulations are intensely focused on chemical migration. For example, the European Union’s framework Regulation (EC) No 1935/2004 is the overarching law, but it’s implemented by more specific measures like Regulation (EU) No 10/2011 on plastic materials. This regulation contains a “Union List” of authorized substances. If a monomer or additive used to make your plastic tray isn’t on this list, it’s illegal to use it in the EU. The regulation also sets specific migration limits (SMLs). For a substance like ethylene glycol, the SML is 30 mg/kg of food. You must be able to provide a Declaration of Compliance (DoC) and supporting test reports from accredited labs proving your trays meet these limits.

Wooden Trays: The primary concern here is phytosanitary risks—specifically, pests and diseases that can travel in the wood. The International Standard for Phytosanitary Measures No. 15 (ISPM 15) is critical. It mandates that all solid wood packaging material (which includes wooden crates or trays used for shipping) over 6mm thick must be treated and marked. The two accepted treatments are heat treatment (achieving a minimum wood core temperature of 56°C for at least 30 minutes) or fumigation with methyl bromide (though this is being phased out). Each compliant piece must bear the IPPC (International Plant Protection Convention) mark, which includes a unique country code, treatment code, and producer code. Failure to have this mark can result in the entire shipment being rejected or destroyed at the port of entry.

Aluminum and Metal Trays: For metals, the concern is often heavy metal leaching. Regulations like the EU’s Commission Regulation (EC) No 1935/2004 set specific limits for metals. For instance, the migration limit for lead is 0.01 mg/kg of food simulant and for cadmium it’s 0.005 mg/kg. Many aluminum trays are also coated with a lacquer or polymer to prevent reaction with acidic foods. That coating then falls under the plastic materials regulation, meaning it must also be compliant.

National and Regional Regulatory Bodies: Key Players

You must comply with the regulations of the destination country. Here’s a breakdown of the major authorities.

Labeling and Documentation: The Paper Trail is Non-Negotiable

Your food trays could be perfectly manufactured, but without the correct paperwork, they won’t clear customs. The documentation serves as proof of compliance. The most critical document is the Declaration of Compliance (DoC). This is a legal document from the manufacturer or supplier that states the food contact material complies with the relevant regulations of the destination market. It should include:

• Identity and address of the business issuing the DoC.
• Identity and address of the business for which the DoC is issued.
• Clear identification of the material or article.
• Date of issue.
• Confirmation of compliance with the relevant regulations (e.g., (EU) No 10/2011).
• Specifications on safe use conditions (e.g., suitable for contact with aqueous foods up to 40°C).
• Supporting data or references to experimental data.

Alongside the DoC, you will need test reports from accredited laboratories. These reports prove that your trays have been tested against the specific migration limits and passed. For wooden trays, the IPPC mark is the primary documentation, but you should also keep records of the treatment process. For all materials, standard shipping documents like the Commercial Invoice and Packing List must accurately describe the goods as “Food Grade Food Trays” or similar, with the correct Harmonized System (HS) code, which can vary by country but often falls under Chapter 39 for plastics or Chapter 44 for wood.

Environmental and Sustainability Directives

Increasingly, regulations are expanding beyond pure food safety to encompass environmental impact. The European Union’s Single-Use Plastics Directive (SUPD) is a prime example. It affects many disposable food trays, especially those made from expanded polystyrene (EPS). The directive restricts the placing on the market of certain single-use plastic products and introduces extended producer responsibility schemes. This means if you are shipping EPS trays into the EU, you need to check if they are subject to these bans or new labeling requirements. Similarly, laws like the UK’s Plastic Packaging Tax levy a charge on plastic packaging with less than 30% recycled content. This isn’t a food safety rule per se, but it’s a critical financial regulation that impacts the cost and legality of your shipment. You must be prepared to provide evidence of recycled content if applicable.

Practical Steps for Shippers and Manufacturers

Navigating this requires a proactive, step-by-step approach. First, identify your market. You cannot comply with every global standard at once; you comply with the standards of the country you are exporting to. Second, engage your material supplier early. A reputable supplier of raw materials for food trays should be able to provide you with a DoC and relevant test data for their product. Third, conduct due diligence testing. Even with a supplier’s DoC, it’s wise to have your finished tray tested by an independent, accredited lab against the standards of your target market. This protects you from liability. Fourth, maintain meticulous records. Keep batch records, DoCs, and test reports for a period that exceeds the shelf life of the product—often several years. Finally, work with a experienced freight forwarder or customs broker. They understand the documentary requirements for different ports and can help you avoid costly delays.
