Exactly 40.0%: An FTA Claim Held Together by Cumulation and a Transhipment

Method. Use the build-down formula with the FOB value as the denominator: RVC = (FOB − value of non-originating materials) ÷ FOB × 100.

Base case, no cumulation. Non-originating materials: motors 96,000 + seals/bearings 26,000 + housings 34,000 + boards 28,000 = 156,000. RVC = (260,000 − 156,000) ÷ 260,000 = 104,000 ÷ 260,000 = 40.0% - meets 'not less than 40%'.

With cumulation. If the controller boards are treated as originating because they come from another party to the same agreement, non-originating materials drop to 128,000 and RVC rises to (260,000 − 128,000) ÷ 260,000 = 50.8%. So the correct comparison is: without cumulation the claim just passes; with cumulation it passes comfortably.

The earlier assumption to avoid is that the goods fail because the boards are foreign. They are not foreign if cumulation is available - they are party-origin inputs.

The change-of-tariff-heading route fails. CTH requires every non-originating material to be classified outside the finished good's heading. The pumps are 8413; the imported cast housings are also 8413. The housings are non-originating (non-party), so the CTH test is not satisfied for that material and the alternative rule is unavailable. Motors (8501), seals (8482) and boards (8537) would satisfy CTH, but one failing material defeats the rule.

Conclusion. Qualification rests entirely on the RVC route, and the margin without cumulation is zero - any valuation adjustment breaks it.

The risk is procedural, not arithmetic. Cumulation is a benefit that must be proved. Whether a supplier's declaration suffices or a full certificate of origin is required depends on the specific agreement's text and its operational certification procedures; many agreements accept a declaration for low-value or for cumulation purposes, others do not. The importer should not assume. The correct step is to read the agreement's origin chapter and its annex on certification, then obtain whatever instrument it names - and keep the supplier's declaration on file with the supplier's details, the originating status claimed, and the period covered.

Why it matters here. Without cumulation the RVC is exactly 40.0%. That is on the line: any reallocation - a small portion of the board price that is non-originating content, a freight or packing element wrongly included in FOB, a currency conversion difference - pushes the calculation below the threshold and the preference collapses.

If cumulation fails, the consequences cascade:

1. Preference denied. Duty is recomputed at the MFN rate of 9% on the full customs value, producing a substantial recovery.
2. Interest and penalty. Duty recovered after release carries interest; a penalty depends on whether the importer knew or should have known the claim was unsupported. A good-faith claim based on a supplier document later found inadequate is treated very differently from a claim with no supporting document at all.
3. Recourse. The importer can seek compensation from the exporter, and the exporter can ask the issuing authority to verify or reissue the certificate.
4. Repeat shipments. Every consignment using the same bill of materials is exposed. The real remedy is to change the sourcing of the housings or the boards so the margin is not zero - for example, sourcing the boards from a party supplier with full documentation, or qualifying the housings through a process rule.

Direct consignment is about control, not about a single vessel. Most agreements allow goods to be transported through a third country provided they do not undergo operations there other than unloading, reloading, splitting, labelling or marking required by the importing party, and provided they remain under customs control. Repacking and re-marking are usually within the permitted list; processing or a change of ownership is not.

What rescues this shipment is documentation showing uninterrupted control: the through bill of lading covering the whole journey, the port's transhipment certificate, container and seal numbers before and after repacking, warehouse or bonded-area records at the transit port, and a non-manipulation certificate. The new cartons bearing local addresses are a fact that invites scrutiny and should be explained, not concealed - they must be shown to be packaging and marking only. If the evidence is thin, expect a verification request to the exporting authority, with the preference suspended in the meantime.

Retroactive issuance. A certificate issued after shipment is normally acceptable if it is issued within the period the agreement allows and bears the required retrospective endorsement. The five-day gap itself is not fatal; a missing endorsement or an issuance outside the window is.

Sequencing the claim two ways. The importer can claim preference at declaration relying on the certificate, or pay MFN duty and apply for a refund within the period allowed from the date of duty payment. The second route is safer when the certificate's validity is doubtful, because it preserves the claim without exposing the importer to a recovery action.

If the certificate is ultimately rejected: duty at 9% is recovered with interest, the importer pursues the exporter, and the case should be logged as a supplier-performance issue affecting all future shipments from that source.
