Rules of Origin (ROO) serve as the legal framework to identify the "economic nationality" of a product. These rules prove that a good actually belongs to a specific country. This identification matters because it determines if you pay the standard tax rate or a discounted rate under a trade deal. Governments also use these rules to enforce trade quotas, collect statistics, and manage anti-dumping duties. Understanding ROO is essential for importers looking to take advantage of the Philippines' Free Trade Agreements.

Two Categories of ROO

Two Ways to Prove Origin

Identifying the Country of Origin becomes complex when global supply chains move parts across many borders. Laws fix this with two main tests:

A. Wholly Obtained

This applies to products that occur naturally or are made entirely within one country. Under the ASEAN Trade in Goods Agreement (ATIGA), this includes agricultural crops harvested within the country, animals born and raised there, minerals extracted from the local soil, scrap or waste from local manufacturing, and products taken from the sea by domestic vessels.

B. Substantial Transformation

If your product uses foreign materials, it must undergo a major change in your country to claim origin. It must become a new item with a different name, character, or use.

Methodology of Transformation

Regional Value Content (RVC)

You calculate the local value added to the product as a percentage of its total cost.

Change in Tariff Classification

This means the final product falls under a different tax category code than the foreign parts used to make it. Correct HS Code classification is essential for this test.

Specific Process Rule

You must perform a specific manufacturing step defined by the trade agreement.

Special Trading Rules

Certificate of Origin (CO)

The Certificate of Origin acts like a passport for the product. The exporter fills it out, and an authority like the Bureau of Customs (BOC) certifies it. Importers must present this document to customs to get tax discounts. The correct form depends on which trade agreement you are using:
