Here is a case study of De Minimis method.
Company A manufactures baby carriages (HS8715.00) in Japan and plans to
export them to Chile under Agreement between Japan and Chile.
A change to heading 87.05 through 87.16 from any other heading; or
No required change in tariff classification to heading 87.05. through 87.16,
provided there is a qualifying value content of not less than 45 percent when the
Build-down method is used, or of not less than 30 percent when the Build-up
method is used.
To prove that the baby carriage qualifies as an originating good of Japan,
Company A decided to choose the CTC rule in this case.
Baby carriage is made from Indian aluminum bar (HS7604.10) and
Chinese handle grip (HS8715.00).
Since handle grip does not undergo “change in tariff classification from
any other heading”, baby carriage does not meet the CTC rule.
But if the value of handle grip (HS8715.00) is equivalent to 10% of transaction
value of baby carriage or less, Company A is allowed to disregard the portion of
handle grip for the purposes of the CTC rule pursuant to De Minimis provision
of Article 32.
