Definition
This card provides a general overview of the sampling procedures for retail packages and finished articles. However, additional requirements may apply to specific products and these are not covered here. Please refer to the appropriate standards and regulations in force.
Retail packages are defined as packages where the weight of the smallest individual pack within the consignment does not usually exceed 5 l or 5 kg, i.e. various cans, bottles, jars and bags.
A retail package should be considered to be any pack specifically prepared for sale to an individual for domestic use.
- In the case of a spice or herb this may mean a quantity as small as 10–25 g.
- For other commodities it will usually mean a package of between 100 g and 2 kg (or 2 l).
- For certain non-homogeneous commodities (e.g. dog food) this may also include sacks or bags up to 25 kg.
This card also provides information on sampling of finished articles whether or not packed in retail sale packages which are not covered in their specific cards.
The articles are defined as finished products, which can be used directly by end users.
This card covers e.g. a variety of products, such as household articles, ornamental articles, sanitary articles, clothes, shoes, objects of personal adornment, tools, mechanical and electr(on)ic equipment, parts and accessories thereof, optical articles, instruments, parts and accessories thereof, watches, furniture, lamps and toys.
These articles consist of different materials, such as plastic, rubber, leather, paper, textiles, mineral products, ceramics, glass and metal or a combination of it.
Excluded are all semi-finished products such as ingots, rods, pipes, sheets, foil, wire, etc. The sampling of these products is covered by the sampling procedure card of the material of which they consist.
For waste articles see specific card for Waste.
Recommended minimum quantity for each final sample
Depending on the quantity in the consignment, the recommended minimum number of packages to be sampled for the purpose of creating an aggregate sample is:
| Lot size (number of packages) | Recommended number of packages to be sampled | |||||
|---|---|---|---|---|---|---|
| 2-100 | 2 | |||||
| 101-1 000 | 3 | |||||
| 1 001-10 000 | 6 | |||||
| 10 001-150 000 | 9 | |||||
| 150 001-500 000 | 12 | |||||
| > 500 000 | 17 |
Adapted from FAO/WHO — CAC/GL 50-2004, table 17 for reduced insp. level. Exceptions to this table are explained in the sampling plan below.
Where the packages are small, ensure that the final sample is at least 250 g. For articles the minimum final sample is one piece of finished and functional product.
If the consignment is homogeneous (all packages have the same label, content, net weight or volume, production or batch number and/or expiry date) fewer packages (or items of articles) may be sampled . In principle the minimum amount/weight of identical final samples , required by the laboratory, according to your national guidelines, should be enough.
Homogeneity: Products packaged for retail sale will usually be mass produced and of uniform composition or homogenous. However for some goods the natural variability of the product may mean that retail packages and finished articles are not uniform or homogenous. In each case you may use your discretion regarding the number of samples drawn.
- Where it is clear that the packages are uniform (e.g. manufactured items with the same production date or batch numbers) the number packages drawn may be reduced whist still being representative of the consignment as a whole. However remember to take the minimum quantity required for analysis.
- Where there is any doubt over the uniformity of the packages, for example where there are visible differences between the contents, you make take additional packages in excess of the quantity required by the scale of sampling to ensure your sample is representative.
- Same is applied for articles: Where there is any doubt over the uniformity of the articles, for example where there are visible differences between then individual pieces, you make take more samples to ensure your sample is representative. An example of not homogeneous goods is e.g. ceramics. Practice shows that the kind of ceramic of articles (porcelain, stoneware, common- and fine pottery) regularly differs within one consignment.
- The articles of high value are usually sampled as one representative piece.
- Where you have not followed the scale, either taking more or less than the scale, you must record your reasons on the sampling form.
Applicable standards (ISO and EU Norms) and relevant legislation

You should also refer to your national legislation and national guidelines regarding sampling.

Some articles of larger size need no containers if a label can be attached easily on them e.g. ceramic products, timber, stone, or products such as electronic devices and apparatus. | |||||||
Safety Precautions and risk assessment
Please refer to your national legislation and guidelines on health and safety.
- Under normal conditions goods in retail packages and finished articles do not present particular health hazards.
- For foodstuffs: no particular hazards unless you have a specific allergy to the contents.
- For other preparations: see SDS or ADR and hazard and safety labels on the original packing.
- Wear protective gloves, safety glasses and/or a protective mask (if necessary).
- You should be aware of and follow any health and safety instructions in the local risk assessment and/or safe working practices for the location where the sampling is to take place.
Sampling plan
| Type of consignment | Description |
| Consignments for customs clearance | The aggregate sample consists of an appropriate number of incremental samples : cans, bottles, jars or bags taken in their unopened retail packing from all parts of the consignment. One sample (one retail sale package or one item of article) is usually taken as representing the goods covered by the same customs declaration. |
| Consignments for excise inspection | |
| The aggregate sample consists of an appropriate number of incremental samples: cans, bottles, jars or bags taken in their unopened retail packing from all parts of the consignment. The minimum number of packages to be sampled is given in the Table above. If the consignment consists of goods originating from one production line (the lot number is identical) a reduced number of samples may be taken. It is also important to consider the proportion of the consignment taken as a sample; see the General principles . | |
