Corrugated Packaging for Export — What Indian Businesses Need to Know
Export is a different game from domestic shipping. A parcel going from Delhi to Mumbai travels for one or two days through a known courier network. A shipment going from Delhi to Dubai, London, or Singapore travels for 20–45 days through ocean containers, multiple transshipment ports, and customs inspection points — in conditions that no domestic logistics system replicates.
The packaging that works for domestic dispatch will frequently fail on an export shipment. Understanding what export packaging requires — and why — is one of the most important things an Indian exporter can do to protect their goods, their relationships with international buyers, and their export reputation. This guide covers it completely.
At a Glance
Export corrugated packaging must meet higher strength standards, moisture resistance requirements, and international marking specifications than domestic packaging. 5-ply is the baseline. Moisture-resistant board grades are essential for ocean freight. VCI inner protection for metal goods, desiccant sachets for moisture-sensitive products, and correct palletisation with ISPM-15-marked wooden pallets are the key additional requirements beyond domestic standards.
Why is export packaging different from domestic packaging?
Export shipments face conditions that domestic logistics simply do not replicate:
- Transit time: 20–45 days by ocean freight versus 1–3 days domestically. The packaging must maintain structural integrity across the entire duration under sustained load
- Container humidity: Ocean containers experience significant humidity fluctuations, especially through tropical sea routes. Standard corrugated board can lose 60–80% of its strength in sustained high-humidity conditions
- Stacking load: Export containers are stacked and loaded to maximum capacity. Boxes must carry full stacking loads continuously for weeks, not hours as in domestic transit
- Multiple handling points: Transshipment at ports adds 3–6 additional handling events compared to typical domestic courier journeys
- Temperature variation: Containers passing through different climate zones experience significant temperature swings that cause condensation inside sealed boxes and accelerate moisture damage
- Customs inspection: Export shipments may be opened and resealed during customs checks at both origin and destination, adding additional handling stress
What corrugated board specification is standard for export packaging?
Export packaging requires a significantly higher board specification than typical domestic packaging:
| Specification factor | Domestic standard | Export standard |
|---|---|---|
| Ply count | 3-ply or 5-ply depending on product | 5-ply minimum for all export applications |
| Moisture resistance | Standard board acceptable | Moisture-resistant coating required |
| Burst strength | Standard grade | Higher burst rating — typically 12–14 kg/cm² minimum |
| Stacking strength (ECT) | Moderate — short duration | High — must hold 4–6 weeks sustained load |
| Sealing method | H-tape on top and bottom | H-tape plus polypropylene strapping recommended |
| Marking requirements | Basic domestic handling marks | International standard markings required |
What are the moisture protection requirements for export corrugated boxes?
Moisture is the primary structural threat to corrugated packaging in ocean freight. Several layers of protection are required for export shipments through tropical or variable-climate sea routes:
- Moisture-resistant corrugated board: Board treated with water-resistant sizing agents that slow moisture penetration and maintain structural integrity in humid container environments across long voyages
- Desiccant sachets inside sealed boxes: Silica gel or clay desiccant sachets absorb moisture vapour inside the closed box, preventing condensation damage to moisture-sensitive products
- Poly liner bags inside corrugated boxes: For food, pharma, and hygroscopic products, a sealed poly liner bag inside the corrugated outer box provides a complete moisture barrier independent of the board
- Container desiccant bars: For full-container shipments, large hanging desiccant bars inside the container itself absorb container-level humidity across the entire voyage
- VCI packaging for metal goods: Volatile Corrosion Inhibitor paper or bags prevent rust and corrosion on bare metal components during long ocean transit periods through humid sea routes
What marking requirements apply to export corrugated boxes?
Export boxes must carry specific marking information that meets the requirements of both Indian export regulations and the importing country's customs and logistics requirements:
Required on every export corrugated box:
- Exporter name and full address
- Importer or consignee name and address
- Country of origin: "Made in India"
- Net weight and gross weight clearly marked
- Box number in sequence (e.g., "1 of 24", "2 of 24")
- Port of destination
- Shipping bill or invoice reference number
Standard international handling markings:
- "Fragile" and "Handle with care" — on all four sides
- "This side up" with directional arrows — on all four vertical sides
- "Keep dry" with umbrella symbol — for moisture-sensitive goods
- Maximum stacking height — "Do not stack beyond X layers"
- Temperature range if product is temperature-sensitive
- Hazmat classification, UN number, and emergency contact if applicable for chemicals or regulated goods
What is ISPM-15 and does it apply to corrugated boxes?
ISPM-15 (International Standards for Phytosanitary Measures No. 15) is an international plant health standard that regulates wood packaging materials used in international trade to prevent the spread of invasive insects and plant diseases across borders.
Corrugated cardboard boxes are generally exempt from ISPM-15 because they are manufactured from processed paper fibre, not raw or minimally processed wood. ISPM-15 applies primarily to:
- Wooden pallets and skids used to carry and transport corrugated boxes
- Wooden crates and cases used instead of corrugated packaging
- Wooden dunnage and bracing placed inside shipping containers
- Any raw or heat-treated wood used as packaging support material
For Indian exporters shipping on wooden pallets — which is standard for most containerised export — the pallets themselves must carry the ISPM-15 mark (a wheat ear with flame symbol and IN country code). Corrugated boxes placed on those pallets do not require the mark. Always verify destination country requirements with your freight forwarder as regulations vary by importing country.
How should export boxes be unitised on pallets?
For containerised ocean freight, individual boxes are typically palletised before loading into the container. Correct palletisation protects boxes during container loading, transit, and destination unloading:
- Stack boxes column-style on the pallet — each box directly above the one below, not staggered in a brick pattern which reduces corrugated stacking strength significantly
- Do not exceed the pallet's rated load capacity or the corrugated box's rated stacking strength for the full voyage duration
- Stretch-wrap the entire pallet unitised load with multiple overlapping layers of LLDPE stretch film to prevent individual box movement during container transit
- Apply polypropylene or steel strapping for heavy or high-value loads as additional securing beyond stretch wrap
- Place pallet protection boards on the top of the stack before stretch-wrapping to distribute pressure from container ceiling contact during heavy loading
Which Indian export sectors use corrugated packaging most heavily?
- Textiles and garments: India's largest export category — fabric, made-ups, and readymade garments shipped in corrugated master cartons to buyers across the US, EU, and Middle East
- Engineering goods: Auto parts, industrial components, machine parts, and hardware — heavy-duty 5-ply with VCI inner protection for metal goods
- Pharmaceuticals: WHO-GMP compliant corrugated outer boxes for medicine export to regulated markets in the US, EU, Africa, and Southeast Asia
- Food and agri products: Spices, rice, processed food, dry fruits, and specialty food — food-safe corrugated with moisture protection for long ocean voyages
- Handicrafts and home décor: Fragile hand-made goods requiring custom-fit corrugated boxes with extensive inner cushioning for safe transit
- Chemicals and cosmetics: Liquid products requiring sealed inner packaging and hazmat-compliant corrugated outer boxes for regulated international shipping
What are the most common export packaging mistakes Indian businesses make?
- Using domestic-grade 3-ply boxes for ocean freight — these fail structurally within weeks of sustained load and humidity
- No moisture protection — standard board without moisture-resistant treatment absorbs container humidity and collapses
- Incorrect or incomplete outer markings — missing country of origin, consignee details, or box sequencing causes customs delays
- No desiccant inside boxes for moisture-sensitive products — condensation damage during tropical sea routes is entirely preventable
- Overpacking to the container ceiling without stacking strength verification — top boxes collapse under sustained load
- Using unmarked wooden pallets — ISPM-15-non-compliant pallets are held at destination customs and released only after heat treatment at the importer's cost
The bottom line
Export packaging is not domestic packaging with a bigger label on it. The transit conditions, duration, handling events, and regulatory requirements are fundamentally different — and under-specifying packaging for export is one of the most common and costly mistakes Indian exporters make, particularly when scaling from domestic to international markets for the first time.
Investing correctly in export-grade corrugated packaging — moisture-resistant 5-ply board, correct inner protection, compliant markings — protects the goods, the buyer relationship, and the export reputation that takes years to build and minutes to damage.

Frequently Asked Questions
Does ASPV Industries supply corrugated boxes specifically for export shipments?
Yes. ASPV Industries manufactures 5-ply corrugated boxes with moisture-resistant board grades suitable for export applications. Custom sizes, higher-grade liner specifications, and international-marking-ready surfaces are available. Contact ASPV Industries to discuss your specific export product, destination market, and volume requirements.
What is the minimum burst strength required for export corrugated boxes?
Minimum burst strength requirements vary by destination country, product type, and buyer specification. Many international buyers and freight forwarders require a minimum burst strength of 12–14 kg/cm² for standard export cartons. For heavy goods or regulated markets, higher ratings may be specified. Always confirm with your freight forwarder or buyer what the destination country and buyer specifically require before ordering packaging.
Are corrugated boxes subject to any phytosanitary certification requirements for export?
Corrugated paper-based boxes are generally exempt from ISPM-15 phytosanitary requirements because they are manufactured from processed paper fibre rather than raw wood. ISPM-15 applies to wooden pallets, crates, and dunnage. However, some destination countries may have specific documentation requirements — always verify with your freight forwarder or the importing country's customs authority before shipment.
How many desiccant sachets should be placed inside an export corrugated box?
Desiccant quantity depends on box volume, product moisture sensitivity, and expected transit humidity. A general guideline is one 50-gram silica gel sachet per 0.03 cubic metres of box volume for standard applications. For highly moisture-sensitive products or long voyages through tropical routes, consult a desiccant supplier for a specific calculation based on your box dimensions and product requirements.
Can the same corrugated boxes be used for both domestic and export shipments?
Not recommended without specification verification. Boxes specified for domestic use typically have lower moisture resistance and burst strength than export requirements. Using domestic-grade boxes for export frequently results in packaging failure during long ocean transit, particularly through humid tropical sea routes. Export-grade corrugated boxes should be specified separately for export shipments even if the same box dimensions are used.
