Dried bird's nest, fish maw, sea cucumber and ginseng-type tonics are high-value, come in many small batches, and rarely improve with age. The category's recurring concerns are five: Chinese labeling and filing, moisture control, pest control, batch and shelf-life records, and stable temperature and humidity without odour transfer. These are general expectations for the category, not a facility only one warehouse can offer.
Dried bird's nest and most dried tonics suit ambient, dry, dark and sealed storage kept off the floor and away from walls: moisture damages shape, colour and texture, and it shows up directly in price. Imported bird's nest also requires registered overseas producers and CAIQ traceability codes under current rules (green for clean edible nest, blue for raw nest, pink for domestic processing), so storage and stock records must tie back to the batch.
Tonics are often handled alongside other food and cosmetic goods, which makes odour transfer and pests real risks; the goods are also high-value, low-volume and multi-SKU, so batches should be checked again before dispatch. Those are the category's general expectations — check them one by one against our actual conditions.
