Customs Value, Freight and Insurance for Regulated Products

Customs value is one of the most contested and error-prone declaration fields, because the tax base is computed directly from it and a small valuation error on a high-volume import becomes a large duty difference. For regulated health products the matter is more delicate still: samples, research shipments and related-party flows do not always satisfy the classic assumption that "invoice price equals customs value". This article explains how customs value is determined, what is added to it and what is left out, how freight and insurance follow the delivery term, and which documents belong in the file for special situations.

Who is this for?

Finance and procurement teams running import accounting and customs operations, sponsors and CROs importing clinical trial materials, companies acting as a manufacturer's Türkiye distributor, related-party importers buying from an affiliate abroad, customs brokers, and quality units preparing for audits. Marketing teams that prepare sample and promotional shipments also need the basics, because even free deliveries carry a value declaration.

Which products does it cover?

The scope is all imported goods, with running examples drawn from the health and research sector: medicines and investigational products, medical devices, IVD kits, reagents, laboratory equipment and their spares and consumables. The valuation-specific issues in this sector are: whether "free" study shipments are in fact embedded in a research service fee; the price split between equipment and bundled installation, calibration and training; and how transfer pricing between affiliates in two countries reflects on customs value.

When does it apply?

Valuation happens for every declaration, but special care is needed when: the invoice price is conspicuously above or below comparable manufacturer prices; buyer and seller are related and the price may reflect that relationship; the price is constructed around post-import resale proceeds; a royalty or licence payment is tied to the import; the shipment is free of charge (samples, warranty replacement, study materials); or service charges are not split out on the invoice. In these cases the valuation file must be built with reasons, not just an invoice.

Legal framework and authority

The framework is drawn by the valuation provisions of the Customs Code and the regulation issued under them; the WTO Valuation Agreement's method hierarchy is reflected in Türkiye's practice. Questions are answered through Ministry of Trade channels, and the Ministry's customs value FAQ page is the official summary this article takes as its reference. The administration checks the value at registration, may verify it later, and can raise additional duty assessments with interest; the importer's defence rests on the documents in the file.

Step-by-step process

1. Define the sale structure: is this import a sale, for what consideration, under which delivery term? Write the structure down.
2. Verify the invoice price: match the payment flow, currency, exchange rate and payment terms to the invoice.
3. Identify additions: commissions, royalties, packing charges borne by the buyer, and tools or dies the buyer supplied to the seller.
4. Sort deductible items: freight, insurance and certain post-importation costs may be deducted only where separately invoiced and documented.
5. Compute the delivery-term effect: decide from the Incoterm whether freight and insurance enter the value and show the calculation.
6. Prepare support for free shipments: file comparable price research, production cost statements or previous sale prices of the same product.
7. For related-party deals, demonstrate price acceptability: transfer pricing documentation, market price comparisons and records showing arm's length conditions.
8. Archive the declaration together with the computation file: the calculation attached to the declaration is your defence in an audit.
9. Refresh the computation when price, rate or structure changes: old assumptions must not silently carry into new shipments.

Document checklist

• Commercial invoice: value, currency, Incoterm, payment terms, product description.
• Contract or order confirmation: the framework showing how the price was formed.
• Payment records: evidence that the consideration was or will be paid at that amount.
• Freight and insurance documents: the split between items entering and staying outside the value by delivery term.
• Royalty/licence agreements and payment records, where import-linked.
• Related-party transfer pricing documentation and comparable analyses.
• Support for free shipments: comparable invoices, production cost statements, warranty/replacement documents.
• Computation sheet: the step-by-step bridge from invoice price to customs value.
• Exchange rate record: the rate at declaration date or as provided by the legislation.
• Archive record: linking the computation file to the declaration number.

Parties and responsibilities

Exceptions and edge cases

Free samples are not value-free: customs builds the base on a comparable value, and an unsupported declaration invites the administration's own estimate. Warranty replacements must document the warranty construct; the line between a genuine warranty flow and a disguised sale will be probed. Leasing constructs may mismatch monthly payments with the value of imported goods, bringing the sequential valuation methods into play. In part shipments, the freight and insurance share falling on each part must be computed; loading an entire consignment's freight onto the first part inflates its value. Where goods and services share one invoice, the service component must be genuinely split and documented; without a split, the full amount may enter the base.

Common mistakes

The most common error is adding or excluding freight and insurance mechanically regardless of the delivery term; the correct treatment follows the Incoterm. The second is divorcing royalty payments from the import file; if the payment conditions attach to import and resale, a valuation question arises. The third is defending an affiliate price as "the group price"; what matters is whether it differs from arm's length pricing. The fourth is leaving no computation trail; without written steps from invoice to value, the audit defence weakens. The fifth is declaring zero for a free shipment, which counts directly as an under-declaration. The sixth is turning one shipment's method into a default for changed circumstances.

Important notice

This article is general information and not legal or customs advice; consult a licensed customs broker for the valuation of a specific shipment and rely on current legislation. Method descriptions here are non-binding and general; valuation rules apply to each shipment on its own facts, and the administration's assessment prevails.
