Because coconut oil undergoes phase changes (liquid to solid), thermal expansion can cause leaks in poorly sealed drums. Ensure the supplier uses high-quality gaskets. For winter arrivals in temperate zones, specify 'Below Deck' stowage on vessels to minimize extreme temperature fluctuations. Always clarify the Incoterms; CIF (Cost, Insurance, and Freight) is common, but FOB (Free On Board) allows the buyer better control over the shipping line's transit time, which is critical for preventing oil rancidity.
