Guide to Understanding the Reference Values

With its continuous commitment to transparency, the Bureau of Customs is providing the Reference Values for various Tariff Headings under the ASEAN Harmonized Tariff Nomenclature (AHTN).

Here’s how the Reference Values are derived.

Through the Statistical Management System (SMS) database, import data covering the ninety (90) day period are extracted. These data are evaluated wherein the outliers such as but not limited to the misclassified goods, goods with extremely high and low values are eliminated.

HS CODE	SUPPLIER	DESCRIPTION	ENTRY NO.	IMPORTER	REG. DATE	BROKER	NET MASS	VALUE F.C./ UNIT (NET)
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	6/19/2017	XXXX	7,069	$3.43
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	6/28/2017	XXXX	6,862	$3.68
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	6/30/2017	XXXX	9,417	$3.68
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	7/14/2017	XXXX	10,190	$3.99
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	8/31/2017	XXXX	13,075	$4.66
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	6/19/2017	XXXX	23,943	$4.68
3701.3000	XXXX	XXXX	P02B C-XXX	XXXX	6/22/2017	XXXX	16,654	$4.68

After the thorough evaluation, the three (3) types of averages i.e., Mean, Median and Mode, are computed.

Mean            =        4.114

Median         =        3.99

Mode            =        3.68

Among the three averages, the second to the lowest value will be considered. This will become the Reference Value of a certain 8-digit AHTN code.
