How to Ship Artwork and Antiques Internationally
Custom Crating: The Foundation of Safe Art Shipping
The standard for international fine art and antique shipping is purpose-built timber crating constructed specifically for each individual piece or group of pieces. A properly constructed art crate is not a plywood box — it is an engineered enclosure designed to distribute impact forces away from the object, maintain the internal environment (temperature, humidity, and vibration), and communicate handling requirements to every party in the logistics chain. The crate frame is typically made from kiln-dried timber to prevent moisture transfer and pest contamination (required for international phytosanitary compliance), with an internal lining of acid-free tissue paper against any object surface, closed-cell polyethylene foam for cushioning, and foam corner protectors engineered to the specific geometry of the piece. For paintings on canvas, the crate incorporates a travel frame — a padded sub-frame that holds the canvas away from the crate walls and prevents contact with any surface during transit.
Paintings on panel (wood, metal, or composite substrates) present different challenges from stretched canvas works. Panel paintings are inflexible and brittle, and are particularly sensitive to changes in relative humidity that cause expansion and contraction of the substrate. Crating for panel paintings typically incorporates a microclimate chamber — a sealed inner environment with silica gel packs calibrated to maintain a specific relative humidity range regardless of external conditions during transit. This level of crating is essential for any panel painting of significant age or value and is the standard applied by specialist art handlers internationally. A general removal company wrapping a panel painting in bubble wrap and placing it in a standard cardboard box is not an equivalent solution, regardless of how carefully it is done.
Thai Export Permits for Antiques and National Heritage Objects
Thailand maintains one of the more rigorous export control regimes for antiques and objects of cultural significance in Southeast Asia, administered under the Ancient Monuments, Antiques, Objects of Art and National Museums Act. Objects that are classified as Thai antiques — broadly defined as objects more than 100 years old that were produced in Thailand or are of Thai artistic or cultural significance — require an export permit from the Fine Arts Department (กรมศิลปากร, กระทรวงวัฒนธรรม). The process involves a physical inspection and valuation of the object by a Fine Arts Department officer, the payment of an export fee based on the assessed value, and the issuance of a NAM (National Antiques Management) export permit document that must accompany the shipment and be presented to Thai Customs at the point of export.
It is important to understand that export prohibition — not just export permit requirement — applies to certain categories of objects. Thai Buddha images and deity figures of certain ages and classifications cannot be exported legally regardless of the applicant's willingness to pay export fees or obtain permits. Religious objects of Thai national heritage significance fall into this category. Attempting to export prohibited objects without proper classification review creates serious legal exposure including potential criminal liability under Thai law. For any antique or religious object of uncertain classification, the appropriate first step is a consultation with the Fine Arts Department before any export arrangements are made. Contemporary works by living Thai artists do not generally require Fine Arts Department permits, though documentary proof of the work's contemporary origin (such as a certificate of authenticity from a recognised gallery) is advisable for smooth customs clearance at the destination country.
Insurance Valuation: Agreed Value vs Declared Value
Fine art and antiques insurance for international transit uses two primary valuation methodologies, and choosing correctly between them has significant financial implications. Declared value insurance covers the item up to the value declared by the shipper at the time of booking — essentially the shipper's own estimate of the object's worth. This is inexpensive and adequate for items whose value is stable and well-documented, such as items with recent auction results or gallery purchase receipts establishing market value. Agreed value insurance — the standard for high-value fine art — involves the insurer agreeing in advance on the value of each piece before the policy is bound, typically based on a formal appraisal by a qualified art appraiser. In the event of a total loss, the insurer pays the agreed value without dispute.
The practical importance of the distinction appears at claims time. Under a declared value policy, an insurer can challenge the declared value and argue that the object was worth less than declared — a dispute that requires the shipper to prove value post-loss, which is substantially harder than establishing value pre-loss through a formal appraisal. Under an agreed value policy, the value has already been contractually established and is not subject to post-loss challenge. For any object worth more than USD 5,000–10,000, agreed value coverage is the appropriate standard. Specialist art and antiques shipping insurance is available through Lloyd's of London market syndicates and specialist brokers; standard household contents insurance and general cargo insurance are typically inadequate for fine art and antiques in transit.
Specialist Art Handlers vs General Movers
The fundamental difference between a specialist art handler and a general moving company is not equipment — it is training, experience, and the institutional knowledge of what can go wrong with specific object types. A trained art handler knows that oil paintings should be transported face-inward (painting surface facing toward the centre of the vehicle) rather than against the vehicle wall; that works on paper are sensitive to the UV light that enters through vehicle windows during long-distance road transit; that bronze sculptures with patination require specific wrapping protocols to prevent patina transfer to wrapping materials; and that certain lacquerwork is extremely sensitive to temperature and humidity fluctuations that would not register as significant in any other context. These are not details that can be improvised — they are accumulated knowledge that prevents irreversible damage to irreplaceable objects. When shipping artwork and antiques internationally from Thailand, the question is not whether to use a specialist — it is which specialist, and what their specific credentials and experience with Thai and Southeast Asian object types are.
