Hand painted screens are fragile and susceptible to moisture and impact. Insist on professional export packaging, which includes pearl cotton wrapping, corner protectors, and a solid plywood crate (not just a cardboard box). For high-value silk screens, vacuum sealing or silica gel packets should be used to prevent mold growth during long sea voyages. Always clarify the incoterms; for fragile art, CIF (Cost, Insurance, and Freight) is often preferred so the cargo is insured against transit damage.
