Chapter 2
METHODS OF PRICING ASSETS, GOODS AND SERVICES
Section I. COMPARISON METHOD
Article 4. Definition
1. Comparison method means a method of pricing a to-be-priced asset, goods or service by analyzing and comparing its price and economic and technical characteristics with great impacts on its price with those of similar assets, goods or services which are traded in the domestic market and, at the same time, referring to regional and world market prices.
2. Similar asset, goods or service means an asset, goods or service of the same type with, identical or similar to the to-be-priced asset, goods or service regarding basic properties such as utility, econo-technical characteristics, shape, size, structural principles, major technical parameters, quality, origin, time of manufacture, production technology and legal characteristics.
3. Comparable asset, goods or service means a similar asset, goods or service with successful sale and purchase transactions in the market which is selected for price analysis, comparison and readjustment based on its elements which can be compared with those of the to-be-priced one.
4. Comparable elements means elements with great impacts on the value of the to-be-priced asset, goods or service, including: trading price, time and conditions (market conditions, sale and purchase conditions, payment conditions and modes); basic properties of assets, goods or services such as legal characteristics, utility, characteristics, major technical parameters, production and circulation costs, quality, origin, time of manufacture and use duration.
Article 5. Pricing bases
1. Successful trading prices of similar assets, goods or services in the market at the time of pricing or a time closest to the time of pricing. Specifically:
a/ For a similar asset, goods or service which is produced or imported for circulation in the domestic market, the successful trading price is the prevailing price determined based on information acquired from such sources as sale invoices or pricing decisions issued by competent organizations or individuals; the import price indicated in customs declarations or supplied by customs offices; the bid- or auction-winning price or registered or declared price; the posted price; the price indicated in price quotations or the price determined by a price appraisal organization. In case there are few assets, goods or services similar to the to-be-priced ones which are circulated in the market and, therefore, no common price is available, the trading prices or bid- or auction-winning prices of these similar assets, goods or services at a time closest to the time of pricing may be used.
b/ For a similar asset, goods or service circulated in the regional or world market, it is the prevailing price determined based on information collected from the following sources: information on the selling price of such asset, goods or service in the regional or world market collected via the internet, mass media and overseas Vietnamese commercial representations, bidding and auction results, price quotations, price offers and actual transactions of organizations and individuals.
All collected data must have their sources clearly stated and reflected in pricing plan dossiers.
3. Brands of assets, goods or services.
4. Normal commercial conditions and generally accepted commercial practices in the domestic, regional and world markets for similar assets, goods or services.
5. Results of price analysis, comparison and adjustment based on comparable elements of similar assets, goods or services used for pricing the to-be-priced asset, goods or service.
Article 6. Pricing steps
Step 1. Collecting information
To conduct market survey and collect information on the prevailing price of each similar asset, goods and service in the market at the time of pricing or a time close to the time of pricing and select at least 3 comparable assets, goods or services; to collect necessary information relating to the to-be-priced asset, goods or service and comparable ones.
Step 2. Analyzing and selecting appropriate comparable elements; making an analysis and comparison table for each comparable element
When selecting comparable elements, it is required to choose those with the greatest impacts on the prices of assets, goods or services and, at the same time, select comparison units suitable to basic properties of assets, goods or services (using such product units as piece, patient bed or chair or units of measurement such as kilogram (kg), ton, meter (m), square meter (m2) or cubic meter (m3)).
Table 1. Price adjustment based on comparable elements
No. | Comparable element | Calculation unit | To-be-priced asset, goods or service | First comparable asset, goods or service | Second comparable asset, goods or service | Third comparable asset, goods or service |
A | Market price | | To be determined | Already known | Already known | Already known |
B | Product unit | | | | | |
C | Adjustment based on comparable elements | | | | | |
C1 | First comparable element | | | | | |
Adjustment rate | % | | | | |
Adjustment level | VND | | | | |
C2 | Second comparable element | | | | | |
Adjustment rate | % | | | | |
Adjustment level | VND | | | | |
C3 | Third comparable element | | | | | |
Adjustment rate | % | | | | |
Adjustment level | VND | | | | |
C4 | Fourth comparable element | | | | | |
Adjustment rate | % | | | | |
Adjustment level | VND | | | | |
| … | | ….. | ….. | ….. | |
| Total net adjustment value | VND | | | | |
D | Adjusted price of comparable assets, goods or services | VND | | | | |
Number of adjustments | | | | |
E | Price selected for the to-be-priced asset, goods or service | | | | |
Step 3. Analyzing and determining the different elements between comparable assets, goods or services and the to-be-priced asset, goods or service; adjusting the price of each comparable asset, goods or service based on the differences among comparable elements so as to find out a price with regard to such asset, goods or service to serve the pricing of the to-be-priced asset, goods or service
Step 4. Adjusting prices on the following principles:
- Adjusting the prices of comparable assets, goods or services based on typical characteristics of the to-be-priced asset, goods or service;
- The price shall be adjusted based on the difference of each comparable element while the remaining comparable elements are fixed (considered to be alike). The adjustment level for each comparable element must be supported with information collected in the market. Specifically:
+ The price of a standard unit of a comparable asset, goods or service will be adjusted up (+) for each element worse than that of the to-be-priced asset, goods or service;
+ The price of a standard unit of a comparable asset, goods or service will be adjusted down (-) for each element better than that of the to-be-priced asset, goods or service;
+ Price adjustment based on the difference in comparable elements may be expressed in a specific sum of money or a percentage increase or decrease in the market price of comparable assets, goods or services.
The total net adjustment value of a comparable asset, goods or service is the total of adjustment levels based on each comparable element with a negative sign (decrease) or positive sign (increase).
- Determining the adjusted price of each comparable asset, goods or service which is equal to its original price plus (+) or minus (-) its total net adjustment value.
Step 5. Determining the price of the to-be-priced asset, goods or service (line E, table 1) which is the price representing the adjusted prices of all comparable assets, goods or services (line D, table 1) or the average of the adjusted prices of all comparable assets, goods or services
The price representing the adjusted prices of all comparable assets, goods or services is the adjusted price of a comparable asset, goods or service which is selected according to the following criteria:
- Being the comparable asset, goods or service with the fewest price adjustments.
- Being the comparable asset, goods or service with the lowest adjustment rate for each comparable element.
- Being the comparable assets, goods or service with the smallest total net adjustment value.
Section II. COST METHOD

- Material price used for pricing a product shall be determined based on the standards, category and quality of used material associated with the place of product manufacture. Specifically:
+ The price of a state-priced material is equal to the price set by the State plus (+) reasonable circulation costs (if any);
- For procured materials: In case of lacking required vouchers and invoices, the price of a procured material is the lowest among the market price notified by a functional organization, price quoted by the producer or price offered by the supplier. In case vouchers and invoices are sufficient as required, its price is the price of another product of similar standards and quality in the same geographical area (region) or the selling price indicated in goods sale/purchase invoices or the bid- or auction-winning price or the posted price plus (+) reasonable and valid expenses (if any) for transporting such material to the enterprise’s storehouse.
The price of a material imported for production is equal to: [the import price (CIF price) plus (+) import duty (+) excise tax, if any] multiplied by (x) the selling rate of the foreign currency set by the commercial bank with which the concerned enterprise has transactions suitable to the payment method prescribed at Point a, Clause 2, Article 9 of this Regulation, plus (+) actual reasonable expenses for transporting such material to the enterprise’s storehouse (if any).
+ The price of a self-produced material is the actual ex-warehousing price plus (+) costs incurred in the production process (if any).
+ The price of a material the processing of which is outsourced is the actual ex-warehousing price plus (+) processing cost plus (+) reasonable expenses for transporting such material to the enterprise’s storehouse (if any).
Material prices and expenses for material processing, transportation, preservation and purchase must be written on invoices and vouchers according to regulations. For materials being agricultural, forestry or aquatic products purchased directly from producers without invoices, the buyer shall make a list of purchased goods clearly indicating the names and addresses of the goods sellers, goods quantity, unit price and total payment.
