Nuts and Dried Fruit Storage in Shanghai

Why nuts and dried fruit should not sit in a plain ambient shed

Nuts are high in oil and sensitive to heat, light and oxygen, so they turn rancid over time. Dried fruit carries sugar and pectin, and once it takes up moisture it softens and mould becomes a real risk. A plain ambient shed cannot hold steady through the damp and hot seasons, and even short-term turnover can leave quality and pest issues behind.

Chinese labelling and simple in-zone processing

Where imported nuts or dried fruit are sold as pre-packaged retail units, Chinese labelling, outer-carton replacement and sorting can be done in-zone. For bulk or ingredient use, check the packaging and marking requirements against your intended use first.

1. Review

   Check the Chinese label copy and layout against imported food labelling requirements.

2. Print

   Print traceable labels per batch to avoid mixed labelling.

3. Apply

   Manual application, with position and flatness controlled and key original markings left readable.

4. Re-check

   Sample-check label quality; anything substandard is corrected on the spot rather than shipped.

Outer-carton replacement, sorting and kitting can run at the same time; labelling and sorting happen inside the climate-controlled zone, so goods are exposed to ambient air, moisture and odours far less often.

Four customs steps for imported nuts and dried fruit

From inbound warehousing through second-line outbound, re-export and inspection support, documents can be pre-reviewed to cut waiting outside the zone and time spent at ambient temperature.

1. Inbound warehousing declaration

   Certificate of origin, invoice, packing list, contract, production date and batch data enter together.

2. Second-line outbound

   Release in lots and declare in batches; duty and VAT settled before release.

3. Re-export and return

   Unsold batches can be re-exported or returned without import duty.

4. Inspection and quarantine support

   We support customs inspection and imported food inspection and quarantine, providing storage and temperature-humidity records as needed.

Nuts and dried fruit storage FAQ

Do nuts and dried fruit always need a climate-controlled zone?

It depends on the category and how long you store it. For oily nuts that go rancid in heat, the industry generally recommends cool, dark storage away from odours; dried fruit that only needs a cool, dry place can go into the ambient-type zones (bonded 4,170m² / general 1,500m²). Tell us the category and turnover cycle and we will check it line by line against what we run.

What humidity level do you control to, and how is mould risk reduced?

The climate-controlled zone holds humidity at 40-60% on automatic control and keeps the records. Industry guidance commonly links mould growth to relative humidity above 65%, and water activity is one of the key indicators for dried fruit. We suggest setting the target from your category and internal standard; tell us the figure and we will confirm whether we can meet it.

How is pest risk handled?

Industry sources generally hold that lower temperatures suppress the development of most stored-product pests, while warm humid conditions favour them. We offer a settable lower temperature band plus inbound inspection and segregated storage. If fumigation or other special treatment is required, raise it separately and we will say plainly whether we can take it on.

Oily nuts oxidise — what is done about that in storage?

Lower temperatures slow oil oxidation, and keeping goods out of the light and away from strong odours limits oxidation and taint. The climate-controlled zone is set at 10-25℃ with humidity 40-60% on automatic control, monitored 24/7 with logs retained. If your goods need nitrogen flushing or vacuum packing, tell us first and we will check that separately.
