Processed and Canned Food Export from Thailand: Loading, Labels and Paperwork

Canned goods, sauces, snacks, noodles, dried fruit, beverages in cartons and similar shelf-stable products are among the easier things to ship from Thailand. They do not need a reefer container, they tolerate a long voyage, and they pack densely. That reputation for being easy is exactly why exporters get caught out. The risks are quieter: a carton crushed at the bottom of a stack, a label that does not meet the destination's rules, a missing certificate that the importer needs on the day of arrival, or a container that arrives with damp cartons and rusted cans.

This guide walks through how a processed food shipment actually moves, in the order the work happens. It covers carton and pallet planning, container loading, labels and ingredient declarations, the certificate types buyers commonly ask for, halal where it matters, moisture and heat, the choice between FCL and LCL, and how shelf life interacts with transit planning. It does not state transit times, fees or duty rates, and it does not claim to describe any destination's current import rules. Those change, and the importer or customs broker at the destination is the authority on them. A forwarder such as TGF can coordinate the booking, the documents and the customs handoff, but cannot decide what your product is allowed to say on its label overseas.

If you are new to exporting at all, read the first-time exporter checklist and the export documents checklist alongside this article, because food adds layers on top of the standard process rather than replacing it.

What shelf-stable means, and what it does not

Shelf-stable simply means the product does not need refrigeration to stay safe and saleable for its stated life. It does not mean the product is indifferent to its surroundings. Cans can dent, seams can weep, pouches can puncture, cartons can lose strength when they absorb moisture, glass can chip, and sweet or fatty products can soften or bloom under heat. Packaging that looks fine on a warehouse shelf may behave very differently after weeks on a vessel, a stack of cargo above it, and temperature swings between tropical loading and a cool destination.

The first practical question is therefore the product's own weak points. Ask what fails first: the carton, the closure, the print, or the contents. A canned product's risk is usually crushing and corrosion of the outer surface. A pouch product's risk is puncture and seal failure under compression. A beverage in cartons is heavy and puts load on the bottom layers. A snack in thin film is light but crushable. The weak point decides the pallet pattern, the carton grade, the use of corner boards and stretch film, and how high you can safely stack.

It also decides whether you need to talk to the buyer about special handling. Some products are sensitive to heat even though they are not refrigerated, for example chocolate-coated items, some confectionery and certain oil-rich foods. If your product is in that group, the plan should include a conversation with your forwarder about positioning in the container and about the season of shipment. For anything that genuinely needs temperature control, read the guide on cold chain for food exports instead, because that is a different category of shipment with different equipment.

Cartons, pallets and how the weight is carried

Most damage to shelf-stable food is mechanical, and most mechanical damage traces back to how the weight is carried. The outer carton is a structural component, not just a label surface. Its grade must suit the weight inside and the height of the stack above it, and it must keep that strength when humid air reaches it. Cartons that pass a quick hand test in a dry warehouse can soften considerably during a humid voyage. If your cartons are heavy, talk to your packaging supplier about moisture-resistant grades, and consider whether the carton is also doing the job of an inner tray.

Palletising is the next layer. A pallet turns many cartons into one handling unit, and a good pallet pattern interlocks the cartons so the stack behaves like one block instead of several columns. Cartons should sit inside the pallet's edge rather than overhang it, because overhang loses carton strength quickly and invites damage from forklifts and neighbouring pallets. Corner protectors, a top sheet and stretch film around the whole stack make the unit stable. Strapping may be added for very heavy stacks. The point is that a pallet should arrive as it was built, even if the container has been jolted.

The pallet itself matters too. If the shipment is going to a market that is strict about wood packaging, the pallet must meet the international treatment standard, and the guide to wood packaging requirements covers that. Plastic pallets avoid the question but add their own considerations. See also the explanation of what a pallet is in freight shipping if your team is new to the terminology.

Finally, remember that palletised cargo travels through at least one forklift hand-off at origin and at destination. Label each pallet and carton face with the marks, product description and batch information that will match your documents. Clear, consistent marking is the least costly protection against a wrongly delivered or wrongly counted pallet.

Loading the container so nothing moves

A container is a steel box that gets lifted, dropped onto trucks, rolled on rails and tilted by the sea. Inside it, cargo that is not secured will shift, and cargo that shifts will crush its neighbours. The container stuffing plan is the document, formal or informal, that decides where each pallet goes, so that weight is spread across the floor, heavy items sit low, and the load is tight from wall to wall.

Start with the container's weight limit. The total of the cargo and its packing must stay within the container's permitted payload, and the verified gross mass must be declared before the box is gated in. Canned food is dense, so many exporters hit the weight limit before they fill the cubic space, which is the opposite of a light snack shipment that fills the box before it gets heavy. Knowing which side of that line your product falls on decides whether a larger container is worth considering. The articles on container sizes, payload and tare weight, and the verified gross mass process explain those terms in detail.

Then think about voids. Gaps between pallets and between the load and the door let cargo move forward when the container is braked or tilted. Fill gaps with dunnage, air bags or load bars, and keep the door area stable so cargo does not lean onto the doors when they are opened at destination. Cartons loaded loose, not palletised, need extra care with layer patterns and bracing.

Load in the order that suits unloading. Mixed loads for several consignees should be stowed so the first to be delivered is reachable. Take photos during loading, record the seal number once the doors are closed, and keep the record with your shipping documents, because it is your evidence if a claim arises later. The guides to container inspection and the seal number cover those points.

Labels, ingredients and allergens at the destination

The label is the part of food export where Thai rules help least. What the pack must say is decided by the destination, and it covers more than the language. Typical areas include the product name and description, the list of ingredients and how additives are named, allergen statements, net quantity and how it is expressed, the name and address of the producer or importer, the country of origin, batch or lot identification, date marking, storage instructions and sometimes nutritional information in a prescribed format. Some markets require the importer's details to appear on the pack or a sticker, some require the label in the local language, and some regulate certain claims such as health or natural.

The single most useful habit is to send the buyer a clean copy of the label and the full ingredient list early, and ask the importer or their customs broker to confirm in writing that it is acceptable. Do this before printing a production run, not after the cartons are packed. Relabelling at destination is sometimes possible, but it adds cost, delay and a handling step, and it may not be allowed at all.

Allergens deserve special attention. Different markets treat different ingredients as allergens that must be declared, and the wording and location of the statement can be prescribed. A product that is acceptable at home can be rejected abroad for an incomplete allergen statement, even though nothing about the food has changed. Cross-contact statements, shared line information and compound ingredients should be reviewed with your quality team and then with the buyer.

Finally, make sure the label, the commercial invoice and the packing list describe the same product in the same words. Customs and food authorities compare them. A mismatch between the product name on the carton and on the invoice causes avoidable questions. See what a commercial invoice is and what a packing list is for what each document should contain.

Certificates and registrations buyers ask for

Beyond the label, buyers and destination authorities often ask for supporting documents. The names and exact requirements vary by market and change over time, so treat the list below as concepts to ask about, not a fixed checklist.

A certificate of analysis is a laboratory report for a specific batch, showing results against an agreed specification, for example microbiological or compositional tests. It is tied to the batch number, so the batch on the certificate must be the batch in the container. Plan lab turnaround into your production schedule, because a certificate that arrives after the vessel departs is of little use.

A free sale certificate, sometimes called a certificate of free sale, is a statement from the competent authority in the exporting country that the product may be sold freely there. Some importing authorities ask for it as part of registering a product. The agency that typically handles this in Thailand is the Food and Drug Administration or another authority depending on the product, so confirm the current process and processing time directly with them.

Manufacturer registration evidence shows that the plant is a recognised food producer. Some destinations maintain a list of approved or registered foreign manufacturers, and shipments from an unlisted plant may be held or refused. Ask the buyer whether the destination requires this, and whether your plant must be registered before the first shipment.

A certificate of origin may be needed to support a preferential duty claim, and a phytosanitary certificate may apply where the product contains plant material in a form the destination regards as risky. See the guides on types of certificate of origin and on the phytosanitary certificate. Health certificates for products with animal ingredients are a separate area, handled by different authorities and rules. Whatever the document, request the exact wording and format from the importer, and check names and addresses character by character.

Halal and other buyer-specific requirements

For some destinations, especially markets with large Muslim populations, halal status is a commercial entry requirement even when it is not a customs rule. Whether it applies, which certifying bodies the destination or buyer accepts, and how the certificate should be presented are questions to verify with the buyer and, where needed, with the certifying organisation. Do not assume that a certificate issued for one market is accepted in another.

Halal is a matter of the whole product chain: ingredients, processing aids, the production line, cleaning and storage. It is also a logistics matter, because halal cargo should not be contaminated by non-halal goods. If a halal shipment is going LCL, ask the consolidator how cargo is segregated, and for FCL, make sure the container is clean and has not carried incompatible goods. Keep the certificate batch or product scope aligned with what is actually loaded.

Other buyer-specific requirements follow the same pattern. A supermarket buyer may require a factory audit report. A distributor may require specific pallet labelling or a particular shipping mark layout. A retailer may specify carton dimensions or barcode placement. Some buyers require quality inspection at loading by an independent party, which is separate from customs. None of these are government rules, but missing them can cost an order as surely as a customs hold. Collect them in one place before production, and write the list into the purchase confirmation so there are no surprises on either side.

The common thread across all of this is ownership of the question. Thai agencies can tell you what Thailand requires of an exporter, but the destination's rules belong to the destination. Ask the buyer to name a contact at their customs broker or a regulator who can confirm in writing, and keep that confirmation with your shipment file.

Moisture and heat: the hidden risks in a sealed box

A container looks sealed, but the air inside it is not dry. Cartons, pallets, packing material and the food itself hold moisture, and a tropical load-out can trap very humid air. As the vessel crosses climates, or as the container sits on a hot deck by day and cools at night, moisture can condense on the steel roof and drip down onto cargo, or condense on cooler cargo surfaces. This is often called container rain or cargo sweat. The result is soft cartons, stained labels, mould on wooden pallets, and rust on tin cans and their lids.

Prevention starts before loading. Make sure cartons and pallets are dry and have been stored away from damp floors. Avoid loading in the rain with the doors open. Use a container that has been inspected and is dry and odour-free. Consider desiccants or moisture-absorbing materials for sensitive cargo, and use liners or wrap where the product justifies it. Do not seal wet packaging inside a container, because it will release its moisture into the closed space during the voyage. The full explanation, with the physics and the practical checks, is in the guide on container condensation and cargo sweat prevention.

Heat is the other half. Containers stacked on deck or sitting in sunlight can become much hotter inside than the outside air, particularly for cargo placed near the roof or walls. Heat-sensitive foods, products with thin chocolate or sugar coatings, oils and some sauces may soften, leak or lose quality. Discuss stowage with your forwarder, ask whether in-deck or below-deck is possible for sensitive cargo, and be cautious about the season of shipment. These are requests to the carrier that may or may not be accepted, not firm commitments.

Finally, protect against odour. Food absorbs smells. A container that previously carried chemicals or strongly scented goods can taint a shipment even if it looks clean. The container inspection checklist is your first line of defence.

FCL or LCL for packaged food, and why it matters for hygiene

The choice between a full container load and a shared container is usually presented as a cost question, but for food it is also a hygiene and handling question. The detailed comparison is in the guide to FCL versus LCL shipping, and the explanations of FCL and LCL cover the basics. Here is how the trade-off looks for processed food specifically.

In FCL, you control the container from loading to sealing. The box is stuffed once, at your premises or at a facility you choose, sealed, and not opened until it reaches the consignee or is inspected by authorities. Your cargo is not mixed with anyone else's, which reduces exposure to odour, spillage, and contamination from other goods. It also gives you control over pallet layout, bracing and marking. For regular volume, or for buyers who are strict about hygiene, FCL is usually the more natural fit.

In LCL, your cargo is delivered to a consolidation warehouse, combined with other shippers' goods, and stuffed into a shared container. Each handover adds a touch. Cartons in LCL need to be robust and clearly marked, because they are moved more times and may sit beside unrelated cargo. For food, ask the consolidator what segregation is practised, whether goods that may taint food are kept apart, and how damp or leaking cargo is handled. LCL can make sense for small trial orders, mixed first shipments to test a market, or low volume to a buyer who can accept the extra handling.

A useful rule is to ask what happens if one carton in the shared container is damaged, leaks or smells, and who would notice before it affects yours. If the answer is uncomfortable, either choose FCL or pack more defensively. Neither mode is better in the abstract. The right one depends on volume, product sensitivity, buyer expectations and the destination's handling of mixed loads. Ask for quotes in both forms and compare them on the same basis rather than on headline price alone.

Shelf life against the transit plan

Shelf life is a clock that starts at production, not at shipping, and the whole journey uses it. Production, quality release, waiting for a cut-off, trucking to the port, time in the terminal, the voyage, any transshipment, clearance at the destination, inland delivery to the importer's warehouse, and distribution to retail all consume part of it. Many buyers set a minimum remaining shelf life that must be left when goods arrive or when they are delivered to the customer. That minimum is a commercial or regulatory term that you should get in writing, and it is the starting point of your plan.

The practical approach is to plan backwards. Begin with the date the product must be on the shelf or in the importer's warehouse, subtract the buffer the buyer requires, then work back through clearance, the voyage, and port and pick-up steps. Use the forwarder's current schedule for each leg, not remembered numbers, because schedules change with the season, blank sailings and congestion. Add contingency, since delays are the rule rather than the exception. The guide to planning lead times for import and export shipments walks through this method, and the articles on blank sailings and port congestion explain why plans slip.

Two things reduce pressure. First, produce close to the sailing rather than building stock early, where the business allows it. Second, agree with the buyer what happens if a delay eats into the remaining life, for example whether goods can be accepted with a short shelf life at a stated adjustment, or are rejected. Decide this before you ship, not at the dock.

Finally, make sure dates are printed consistently. Production date, best-before or expiry format, and batch codes must match across the product, carton, certificate and invoice. A missing or illegible date is one of the most common reasons for a rejected food shipment, and it cannot be fixed once the container has sailed.

A practical sequence, and where a forwarder fits

Putting it together, a food export usually goes best when the work is done in this order. First, confirm the destination rules with the buyer and the importer's customs broker: label content and language, allergens, registrations, certificates and any halal need. Second, finalise labels and start the certificates, because those depend on outside parties and lab time. Third, design the carton, pallet and container plan around the product's weak points and the container's weight limit. Fourth, choose FCL or LCL and book with cut-offs that work back from the destination's receiving window and the shelf-life clock. Fifth, load carefully, photograph the process, record the seal and weights, and do a final check that names, descriptions and batch numbers match across every document. The detailed pre-shipment checklist and the export documents checklist are useful companions for that last step.

The forwarder's role is to coordinate the physical and document chain: booking, container and space, haulage, consolidation if LCL, export customs handoff and documents flowing to the carrier and the consignee. A forwarder such as TGF can help you plan the container and the schedule and prepare the shipping documents with you. What the forwarder cannot do is decide what the destination permits on a label or what certificates a destination authority requires. That information comes from the importer, the importer's customs broker or the relevant authority, so ask for it in writing and verify it close to the shipment date.

If something goes wrong in transit, such as damaged or wet cargo, the documents you kept, including photos, seal numbers and packing records, are what support a claim. The guides to cargo damaged in transit and to cargo insurance explain what to do and what cover may respond. Treat the first few shipments as learning runs, keep a short note of every question the buyer asked, and fold the answers into your standard process. After two or three shipments, most food exporters find the work becomes routine.
