Registered US LLDPE imports need a contingent-duty exposure file

The Trade Remedies Authority case AD0091 was still active when checked on 9 September 2026. Trade Remedies Notice 2026/19 says that, where a definitive remedy is implemented for registered goods, duties may be payable from a date up to 90 days before any provisional remedy. The eventual definitive decision determines the level charged.

For a UK manufacturer or packaging converter that directly imports the covered resin, waiting for a rate can leave the finance response too late. The useful preparation is a declaration-level exposure file that separates four things: whether the goods enter the registered population, who may hold the customs debt, the size of a transparent planning scenario and how much commercial recovery is supported by signed evidence.

Registration creates a population to examine

The notice covers LLDPE originating from the United States (US) and lists twelve UK Global Tariff commodity codes. Importers use additional code 8C11 for products inside the notice and 8W02 for products outside it.

Those codes provide a starting point. A finance record also needs the import date, product specification, origin evidence, customs value, declaration reference and the identity of the declarant and represented person. A broad tariff heading or supplier address cannot settle the product and origin questions by itself.

The registration requirement continues until the investigation terminates. The public case file shows importers, exporters, an industrial user and the applicant participating in the process. Their presence confirms that the case reaches a live supply chain. It does not establish the outcome, rate or commercial position of any participant.

Retrospective collection has several gates

Registration gives HMRC the records needed for a possible later assessment. The statutory route remains exceptional.

Regulation 91 of the Trade Remedies Regulations requires the Trade Remedies Authority (TRA) to consider a history of injurious dumping or importer awareness, a massive volume of dumped goods in a short period and circumstances showing that prospective application would seriously undermine the remedy. Importers must have an opportunity to submit relevant evidence before the TRA recommends retrospective application.

The TRA's current investigation guidance explains that a provisional affirmative determination can lead to a guarantee, while a definitive measure can follow later. It also describes retrospective measures as an exceptional response.

The finance file should carry a contingent scenario. Registration status, legal contingency and planning exposure belong in separate fields, and none should be presented as a forecast.

Keep customs debt and commercial recovery separate

HMRC's customs debt guidance includes anti-dumping duties within customs debt. Its liability manual says the declarant and the person on whose behalf a declaration is made can both be debtors. The exact representation arrangement needs to be checked for each entry.

A supply or customer contract answers a different question: whether part of a future amount can be recovered commercially. The exposure file should reduce its gross scenario only for signed or specialist-verified recovery. An expected negotiation, broad price-review clause or informal supplier assurance belongs in the action plan until its value is confirmed.

This separation prevents two common errors. The first is treating a customs agent's involvement as proof that the importer has no exposure. The second is subtracting hoped-for customer recovery from the finance view before the contract position has been tested.

Build a transparent scenario range

The notice sets no duty rate. A planning rate must be labelled as an internal scenario chosen before the calculation. It cannot be presented as the likely TRA result.

Use the same arithmetic for every record:

eligible customs value × scenario rate = gross planning exposure

gross planning exposure - verified recovery = net planning exposure

For £500,000 of registered customs value, scenario rates of 5%, 10% and 15% produce gross amounts of £25,000, £50,000 and £75,000. A documented £20,000 recovery would reduce those net scenarios to £5,000, £30,000 and £55,000.

The finance director should set the scenario rates and cash or margin tolerance before reviewing the portfolio. Changing either after seeing the answer weakens the decision. Customs, accounting and legal specialists should confirm any judgement that falls inside their field.

A complete record changes the action

Consider a fictional packaging manufacturer that has locked a 10% planning rate and a £25,000 net-exposure tolerance. The purpose is to decide which records need immediate action while the legal outcome remains open.

The July import has complete US-origin and product evidence, an 8C11 declaration and £400,000 of customs value. The company has no verified recovery. Its gross and net scenario is £40,000, which exceeds the tolerance. Its primary route is finance headroom protection, owned by the finance director, with accounting review as the next action.

The August import also has £400,000 of customs value and a £40,000 gross scenario. A signed provision, reviewed by the appropriate adviser, supports £30,000 of recovery. The £10,000 net scenario sits within tolerance, so the primary route is documented monitoring.

The September import has the same £40,000 gross scenario and £5,000 of verified recovery. Its £35,000 net scenario exceeds tolerance. The primary route remains finance headroom protection. A specific contract clause, named counterparty, documented amendment proposal, estimated additional amount and specialist-review status also support a parallel commercial recovery action. Finance owns the exposure record while the commercial lead owns that parallel action.

An October order has no complete origin evidence. Its exposure cannot be set to zero. The customs lead must resolve origin and declaration treatment before finance relies on a final number or the commercial team fixes the customer price.

Each primary route follows from a visible difference in evidence. The optional commercial action never replaces the primary finance route when net exposure remains above tolerance.

Use one primary route and one optional parallel action

Evidence check is the primary route when product, origin, date or customs-debtor evidence is incomplete. The customs or trade lead owns the missing record and sets a due date. Review occurs when the missing evidence arrives or the due date is reached. Close evidence checking when the field is resolved and the record is recalculated into its next route, or when the investigation terminates without a measure that applies to the record. The business should avoid presenting zero exposure while the evidence remains unresolved.

Documented monitoring is the primary route when the record is confirmed outside the registered population or when the net scenario sits within the pre-set tolerance. The finance director owns the monitoring record. Review is triggered by a new TRA notice, changed product or origin evidence, or revised commercial recovery. Close the record when the investigation terminates without a measure that applies to it, or when specialist-confirmed evidence places it outside the registered population and the supporting record has been retained.

Finance headroom protection is the primary route whenever a complete, in-scope record has net exposure above tolerance. The finance director owns the exposure decision and accounting review. Review occurs when the TRA publishes a new notice or verified recovery changes. Close the scenario control when the investigation terminates without a measure that applies to the record, when verified recovery reduces net exposure to tolerance or below, or when an assessed amount replaces the scenario and moves into the company's accounting and settlement control. Procurement can prepare an alternative source where qualification, availability and total cost are evidenced. A switch made without those facts can replace contingent duty exposure with a supply or performance problem.

Commercial recovery is a parallel action only where the primary route is finance headroom protection and a documented recovery opportunity exists beyond the amount already verified. The minimum evidence is a named counterparty, a specific contractual clause or written amendment proposal, an estimated additional amount and timing, and the current specialist-review status. The commercial lead owns the action. Close it when an executed instrument converts the amount into verified recovery, the specialist confirms that no enforceable right exists and no amendment will be pursued, or the counterparty rejects the written proposal by the recorded decision deadline. Finance keeps the primary route until verified recovery reduces net exposure to the locked tolerance or below.

Open one control record for every declaration or commitment

Use the record below for imports made since 2 July and for open commitments expected to enter the same scope.

Start with the declarations already registered. Add future commitments before price and supply decisions are fixed. The result is a finance view that can change as the official case and company evidence develop, without turning an unknown rate into a confident prediction.
