Cosmetics Storage Temperature: A Warehouse Checklist

The right cosmetics storage temperature is whatever the product label says; for most products the baseline is a cool, dry place out of direct sunlight. The real challenge is the climate where your warehouse sits.

Hong Kong Observatory climate normals for 1991–2020, for example, show a July mean temperature of 28.9°C with a mean daily maximum of 31.6°C, and mean relative humidity of 83% in April and May. This guide sets out what buyers should check when receiving and storing cosmetics in hot, humid conditions. It does not discuss product benefits.

Step 1: Read the storage instructions on the pack

Start with the product itself. Korea’s Cosmetics Act¹, Article 10, requires packs to show the expiry date or period after opening and precautions for use, and product-specific storage conditions often appear there.

Article 2 defines the expiry date as the minimum period during which, under appropriate storage, the product keeps its characteristics and can be used safely. In other words, shelf life assumes proper storage.

Record on receipt:

• each product’s storage instructions (refrigerate, cool place, avoid sunlight, etc.);
• batch numbers and expiry dates (or manufacture date and period after opening);
• items that need special care, such as balms and sticks that soften in heat.

Step 2: Know the temperatures where you store

The Hong Kong Observatory’s 1991–2020 climate normals² give these summer figures:

These are outdoor readings at the Observatory. Unventilated warehouses, container interiors and top floors under a roof can get hotter, so keep a thermometer in the store and log actual readings.

Step 3: Control humidity and condensation

In the same normals, Hong Kong’s mean relative humidity peaks at 82% in March and 83% in April and May. High humidity softens paper unit boxes and cartons and lifts labels. Check that:

• cartons sit on pallets or shelving, not directly on the floor;
• stock is kept away from walls so air can circulate;
• cartons are inspected right after moving between air-conditioned space and outdoors, when condensation forms.

Step 4: Keep stock away from light and heat sources

Avoid sunny windows, spots directly under lighting and areas near machinery. The same applies in shops: one option for sunny display windows is to use dummy units rather than saleable stock.

Step 5: Rotate stock and track expiry

Choose first-expired-first-out (FEFO) or first-in-first-out (FIFO) and manage inventory by batch number. Good rotation cuts returns and write-offs.

ISO 22716, the international GMP standard for cosmetics, gives guidelines for production, control, storage and shipment, but according to the Estonian Centre for Standardisation’s summary it does not apply to research and development or to the distribution of finished products.

A distribution warehouse may sit outside its scope, yet principles such as separate storage areas, clear stock identification and records are still worth borrowing.

Step 6: Manage the transport leg too

Goods are often exposed to heat before they reach the warehouse, especially in summer sea containers or while waiting outdoors for clearance. Insurance for transit damage is covered in cargo insurance ICC A, B, C, and what to do if goods arrive damaged in damaged shipment claims. Why balm textures are heat-sensitive is explained in cleansing balm vs cleansing oil.
