An importation transaction is commercially sound only when its margin survives customs assessment and the cost of bringing the goods into usable inventory. The supplier’s invoice is the starting point, but it does not answer the questions that determine the final exposure: what value Customs may assess, which tariff treatment applies, what taxes must be funded before release, and which destination charges remain for the importer’s account. These issues belong in the procurement decision, before the purchase order becomes a commitment.

Under Sections 700 and 701 of the Customs Modernization and Tariff Act, Republic Act No. 10863, transaction value is the primary valuation method when its conditions are satisfied. It rests on the price paid or payable for export to the Philippines, with prescribed adjustments. Freight, insurance and certain other additions may therefore matter even where the commercial invoice shows a lower goods-only amount. Valuation is a statutory exercise; a supplier’s preferred invoice description or billing arrangement does not settle it.

Tariff classification and origin must then be examined independently of price. The BOC’s importation guidance directs importers to provide accurate commodity details and consistent supporting documents, and to check regulatory requirements. In practice, procurement teams should obtain specifications, composition and intended use early enough for a meaningful classification review. A description such as “accessories” may be convenient for purchasing, but gives the reviewer little basis to assess the product’s treatment or identify a permit issue before shipment.

Import VAT is another frequent source of underbudgeting. Section 107(A) of the National Internal Revenue Code, as amended by Republic Act No. 10963, generally imposes 12% on the customs value plus customs duties, applicable excise taxes and other charges; it also provides a distinct basis where duty is assessed by quantity or volume. Accordingly, simply applying 12% to the foreign supplier’s invoice can understate the requirement. Applicable exemptions must be established on their own legal and documentary basis.

An illustration shows the effect. Assume a customs value of ₱1,000,000, an ad valorem duty rate of 5%, no excise tax and no additional amounts in the VAT base solely for this simplified computation. Duty would be ₱50,000; VAT on ₱1,050,000 would be ₱126,000, producing ₱176,000 in combined duty and VAT. The assumed 5% is not a product-specific tariff determination, and actual assessable charges would change the result. The example isolates the relationship between duty and VAT rather than presenting a shipment quotation.

Currency exposure also needs a separate line in the budget. The BOC publishes exchange-rate circulars for stated periods, including a circular listed for 17–23 October 2026. Treasury’s rate for settling the supplier and the rate applicable to the customs computation serve different purposes. A costing sheet should identify both assumptions and carry a revision date. Otherwise, an apparently firm peso margin may depend on a conversion figure that no longer matches the assessment or the supplier payment.

Beyond the assessment, the contract must allocate transport, insurance and destination expenses with sufficient precision. An “all-in” quotation is commercially useful only if its inclusions, exclusions, named destination and validity are clear. The importer should be able to distinguish government assessments from carrier, terminal, transport and professional charges, and identify what becomes payable if release or delivery is delayed. This is our commercial recommendation: price the shipment against a documented allocation of costs, rather than a single headline freight figure.

The practical objective is a costing file that can support both the declaration and the business decision: product specifications, purchase terms, valuation support, origin documents where relevant, permits and an itemized funding schedule.

Resolving these matters before dispatch protects the importer’s negotiating position and provides a firmer basis for pricing, inventory commitments and working-capital planning.
