In Europe, the food hygiene rating for mobile catering vehicles is as stringent as that for fixed restaurants. Journalists learned that in the container coffee shops recently exported to France, all interior walls are covered with 304 stainless steel, with polished welds and no dead corners, making cleaning easy and allowing the units to pass on‑site inspections by the French DDPP (Directorate for Food Protection). In addition to the walls, the areas around the cooking ranges, the grease collection chambers of range hoods, and the countertops of deep fryers are also uniformly made of stainless steel. Domestic container conversion companies say that while in the past containers exported to Europe were mostly used for storage, the shift to food service has led many clients to explicitly require "full stainless steel walls", which has become a technical standard for entering the EU market. Industry analysts believe this high standard is pushing China's container modification industry to upgrade from "low‑end refurbishment" to "food‑grade finishing".
