How to read a shelf-life claim before planning an export route
By VegoFresh Editorial Team · Published
Storage observations, internal trials, company records and news reports answer different questions. Here is how to assess the evidence before choosing an export route.
Evidence and route conditions are named in the article. Results for one crop or setting should be checked against the buyer’s own arrival standard.

“Keeps for 60 days” sounds decisive until you ask: which crop, in what pack, under which conditions, and judged by whom? A storage result can help screen a route. It does not, on its own, tell an importer what will be saleable after unloading and distribution.
We label the evidence behind our case summaries so buyers can see what each result supports. Here is how to use those labels when considering a fresh-produce shipment.
Four kinds of evidence answer four different questions
Controlled storage data shows what happened to a defined sample under recorded conditions. Ask for the variety and maturity, sample size, pack, temperature and humidity, inspection dates, and the quality threshold used to end the test. A good storage result is a reason to test a route, not a route result.
An internal trial tests a proposed treatment or pack, sometimes under simulated journey conditions. It can reveal which parameters deserve a larger test. For example, the company presentation describes a 15-day storage trial for tree-ripe Yunnan strawberries. It labels that an experimental case; it does not describe a 15-day international shipment or buyer acceptance on arrival. Read the strawberry trial summary.
A company record describes a project, client or commercial activity reported by the company. The Tonghai vegetable account in our source materials says vegetables were kept for 45–60 days under its process and that Tonghai broccoli was sent to the Middle East by sea in November 2023. These are two distinct statements. The presentation does not provide shipment-level temperature logs, arrival grading or repeat-route results in the excerpt we have. Read the Tonghai case summary.
A news report is an account by a publisher of a particular event or result. A 15 May 2010 PLA Daily report gives preservation periods of more than 40 days for spinach and xiao baicai, and around 60 days for youmai cai, in a naval shipboard programme. It is useful evidence of what was reported in that setting. The public reprint does not identify a commercial supplier or provide a refrigerated-container protocol. Read the naval report summary.
Project listings, contracts, patents and awards can support claims about participation, scope or intellectual property. They do not by themselves measure how much produce a buyer can sell after a shipment.
Storage time and selling time are different
A storage test follows produce for a stated period under its test conditions. An importer needs a different answer: at the point of delivery, how much meets the agreed grade, and how long will that accepted stock remain saleable through the buyer’s normal distribution and sales cycle?
That answer depends on the full journey. Time from harvest to cooling, port dwell, transit, border clearance, unloading and local delivery all consume time and expose the crop to handling and temperature changes. A storage-day figure should therefore be paired with an arrival inspection and a post-arrival hold under realistic market conditions. Subtracting sailing days from a laboratory figure is only a planning sketch; it is not an arrival-quality promise.
Turn a promising result into a route decision
For a proposed crop and destination, a useful assessment has five parts:
- Set the buyer’s standard. Define variety, maturity, packaging, acceptable defects, minimum accepted percentage and the selling window required after delivery.
- Map the actual route. Include packing, pre-cooling, inland transport, port and customs dwell, sea transit, unloading and onward distribution. Use a range for uncertain delays.
- Test the exact crop and pack. Run controlled storage checks with recorded conditions and quality measurements. Include a realistic period after opening or transfer.
- Trial the shipment. Use temperature records and documented inspections at loading and arrival. Record accepted weight, defects and remaining selling time; repeat when season or origin changes materially.
- Compare landed cost per accepted kilo. Freight savings matter only alongside the quantity a buyer can actually sell and the time available to sell it.
The answer may be “ready for a route trial,” “change the pack or handling plan,” or “keep this crop on a faster route.” Each is more useful than a general shelf-life claim. See the ocean-route assessment process or request an assessment for your crop.

Tell us the crop, origin, destination and arrival standard. We can identify which records are relevant and what still needs validation.
