When shipping artwork or sensitive media, crate labeling and sealing aren’t mere afterthoughts—they’re essential safeguards. Proper labeling communicates handling instructions, while thorough sealing protects against environmental risks and tampering. This comprehensive guide offers step-by-step best practices, covering materials, crate designs, sealing methods, and why Union Fine Art Services is your ideal partner.
1. Labeling Crates: Clarity, Compliance & Communication 🎨
1.1 Use Clear, Durable, and Informative Labels
- Waterproof and permanent: Use ink and adhesives designed to resist moisture and rough handling.
- Can’t ignore: Every side of the crate should feature clear labels—Fragile, Do Not Stack, and This Side Up are must-haves.
1.2 Include Essential Information
- Content description: List item type, title, artist’s name, and ownership details.
- Contact info: Provide sender and receiver names, addresses, and reliable contact methods.
- Handling instructions: Use arrows for orientation; mark “Do Not Stack” for delicate pieces.
- Tracking/barcodes: Include shipment labels, tracking barcodes, and tamper-evident seals.
1.3 Label Placement & Design
- Multiple sides: Place labels on all accessible crate faces—front, back, left, right, top, and bottom, if possible.
- Orientation arrows: Always show the crate’s upright position to prevent mishandling.
- Bright colors: Use vivid hues (e.g., red, orange) or pre-made labels for visibility.
1.4 Internal Labels & Documentation
- Artwork info inside: Place a label or condition report that includes materials, execution date, handling, and provenance.
- Packing list: Include inventory and condition reports sealed inside a plastic pouch or folder.
- Repacking instructions: Attach guidelines to facilitate smooth unpacking and future shipments.
1.5 Avoid Overly Specific Crate Content Labels
Explicitly listing “contains artwork” could draw unnecessary scrutiny. Labels like FRAGILE – Handle With Care are effective without attracting unwanted attention.
2. Sealing Crates: Robust Protection from tampering, moisture & pests
2.1 Choose the Right Construction Materials
- Plywood thickness: Use ≥12.5 mm for side walls and ≥19 mm for the base for strength and form.
- Interior vapor barriers: Consider Tyvek or equivalent liners to control humidity.
- Glue standards: Use waterproof, structural glue; for international shipments, heat-treated wood compliant with ISPM‑15 is required.
2.2 Use Secure Closures and Screws
- Washers plus screws tighten lids firmly; draw latches and hinge systems may be better for repeated openings.
- Avoid nails: Screws are more reliable and reusable.
2.3 Implement Multi-Layer Sealing
- External tape and strapping: Use reinforced tape across seams and galvanized steel or plastic strapping to resist shifting.
- Sealant application: Apply silicone or polyurethane sealant to edges and joints to block moisture.
- Tamper-evident seals: Add serialized or easily breakable seals to detect unauthorized opening.
2.4 Moisture Control and Pest Protection
- Waterproof lining: Inside liner + sealant helps prevent dampness.
- Desiccants: Include silica gel or vapor‐barrier bags in crates with sensitive media.
- ISPM‑15 compliance: Use heat-treated or fumigated wood to comply with international plant clearance regulations.
2.5 Structural Integrity & Testing
- Reinforcing cleats and battens every ~60 cm adds rigidity.
- Forklift access: Incorporate skids and handles for safe handling.
- Movement check: After sealing, shake the crate; internal contents shouldn’t shift.

Below is a step-by-step outline of combining the above best practices with Union’s professional approach:
| Step | Task | Why It Matters |
| 1. Prep & Wrap | Clean item and wrap in acid-free glassine; add foam & corner protectors. | Guard surface, corners, and edges. |
| 2. Measure & Build Crate | Use correct plywood, framing with cleats, vapor liner, and sand kids for handling. | Ensures structural integrity and ease of transport. |
| 3. Cushion & Secure | Foam inserts, silicone sealant, desiccants, and secure strapping. | Protects from shock, moisture, and pests. |
| 4. Close & Seal | Use screws, draw latches, tight tape, and tamper seals. | Keeps the crate secure and monitors tampering. |
| 5. Label Inside + Outside | External: Fragile, orientation arrows, handling info; internal: artwork data, packing lists. | Clear instructions for handlers; internal documentation for recipients. |
| 6. Documentation & Compliance | Affix transport labels, generate packing lists, and ensure the ISPM-15 mark. | Enables seamless customs clearance. |
