After the Supreme Court struck down IEEPA, US duty became a three-layer stack: MFN, a Section 301 country layer and product-specific duties. With USD 166bn of refunds still being paid out and 178 exclusions expiring on 10 November, here is how fabric importers should reprice 2027.
If you priced your 2027 roller shade fabric programme using the tariff model you built in 2025, that model is now dead. Not slightly off — three times rewritten. On 20 February 2026 the US Supreme Court ruled 6–3 in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act (IEEPA) does not give the President authority to impose tariffs. Customs stopped collecting IEEPA duties on 24 February, and a flat 10% global tariff took effect the same day under Section 122 of the Trade Act of 1974. Section 122 has a hard 150-day ceiling; it expired on 24 July 2026, and the same day the US Trade Representative replaced it with Section 301 “forced labour enforcement” duties on roughly 60 economies — 10% for nineteen of them, 12.5% for the other forty-one. China sits in the 12.5% tier, and that 12.5% is stacked on top of the long-standing China Section 301 list duties (7.5% to 100% depending on the line), with no most-favoured-nation offset.
This article is not about politics. It is about money. A US importer buying coated blackout fabric from China for finished roller blinds now faces a landed-cost structure that has nothing to do with 2025 — while a refund process launched in April 2026 is still paying out money that many fabric importers have not claimed, and 178 product exclusions expire on 10 November 2026. Three events landing in the same quarter is the reason to recalculate now, not when you quote in Q1.
1. The tariff is a stack, not a number
Duty on a US import is now a layered structure: the base most-favoured-nation rate set by the ten-digit HTS code; a country layer added on 24 July 2026 under Section 301 (10% for nineteen economies, 12.5% for forty-one, China included); and product-specific layers — the existing China Section 301 lists and Section 232 duties on steel, aluminium, copper, lumber and furniture. A home-textile item with a 5% MFN rate and a 25% legacy China 301 rate now lands at roughly 42.5% once the 12.5% country layer is added on top.
For window-covering fabric specifically, four code families matter and they behave differently: woven fabrics of synthetic filament yarn (HS 5407), coated or impregnated fabrics (5903 and 5907), made-up curtains, blinds and valances (6303), and hardware — tubes, brackets, end caps, clutch and chain (largely under 8302). Rates differ, origin rules differ, and whether a line sits on a Section 301 list differs. Mixing fabric and finished product into a single quoted price is the single most common costing error we see in 2026, particularly when a buyer asks a mill for a DDP door price: the seller quotes ocean freight and quietly ignores the duty stack.
2. The IEEPA refund is real, but it is rationed by procedure
US Customs and Border Protection is paying IEEPA refunds through its CAPE module in phases. By the end of July 2026 about USD 100 billion had been returned. Total IEEPA collections were roughly USD 166 billion, of which an estimated USD 11.4 billion sits on entries that have already reached final liquidation and can only be recovered through litigation and a court-ordered reliquidation. CAPE Phase III opened on 6 October 2026, but only for plaintiffs who had already filed at the Court of International Trade (CIT). Under current mechanics, CBP liquidates an entry roughly ten months after import, and once 80 days have passed from liquidation, the standard refund route closes.
The result is a two-tier system. Importers with legal budgets are collecting; small importers are stuck at the procedural gate. Around 7,000 companies had filed at the CIT by early November 2026, and on 2 November the Liberty Justice Center — which argued the lead IEEPA case — launched “Operation Refund Rescue” to cover filing costs for qualifying small businesses, initially capped at 100 cases.
What this means for an overseas supplier is concrete. If your US customer imported your fabric between April 2025 and February 2026, there may be a refund on their books. Who keeps that money depends on the contract, not on who paid for the goods. A DDP seller who absorbed the duty and never wrote a refund clause has effectively donated the recovery to the buyer.
3. Four clauses to replace “duty is for the buyer’s account”
First, allocation: which party bears the country layer and which bears the product layer, and what triggers a change — the Federal Register publication date, the date of shipment, or the date of entry. Second, refund ownership: state who holds the IEEPA refund claim and who receives the proceeds, especially under DDP. Third, a price-adjustment mechanism: a numeric threshold (“if the applicable rate moves by more than X percentage points, either party may reopen the price”) rather than a generic force majeure clause — tariffs are a foreseeable commercial risk and most force majeure wording will not carry them. Fourth, declaration responsibility: who carries administrative and criminal exposure for under-valuation or misclassification.
That fourth point acquired real weight in 2026. Executive Order 14411, signed 3 June 2026, made importer eligibility a precondition for clearance. The Trade Fraud Task Force set up by the Department of Justice and DHS in August 2025 announced on 14 July 2026 that it had generated more than USD 1 billion in civil, criminal and forfeiture recoveries in under a year, about USD 640 million of it from tariff-evasion cases under the False Claims Act. The same day DOJ created a standing Global Trade and Commercial Enforcement Section, moving trade prosecutions from a policy-cycle task force into permanent organisational structure. CBP has assessed more than USD 2.1 billion in commercial penalties in fiscal 2026 to date and debarred 35 entities from federal contracting; in May 2026 an aluminium importer and affiliates settled anti-dumping and countervailing-duty evasion allegations for USD 549.5 million.
The False Claims Act pays whistleblowers 15% to 30% of recoveries. Whistleblowers can be former employees, competitors, unpaid service providers or a freight forwarder. “We can declare it a bit lower for you” is therefore not a favour in 2026; it is a liability with a bounty attached to it, and the party most likely to collect is someone who already knows the file.
4. Origin tiers are not interchangeable
Since 24 July 2026, roughly 109 economies outside the Section 301 forced-labour list carry no country layer at all after Section 122 lapsed — only MFN. The ~60 covered economies add 10% or 12.5%. India is in the 10% band; Vietnam, Bangladesh, Indonesia and Cambodia are generally in the 12.5% band; the EU and Taiwan are computed at a 10% ceiling net of MFN, so the total lands at the ceiling rather than above it; Japan and Korea are capped at 12.5%. Canada and Mexico can reach zero on goods that qualify under USMCA and fall outside Section 232.
Textiles carry a hard constraint: USMCA textile rules are yarn-forward. Fabric woven in China, shipped to Mexico and cut and sewn into finished roller blinds will normally fail the origin rule. The same logic applies to coating in Vietnam before US export — without a substantial transformation, the origin stays Chinese. Origin and transshipment are an explicit 2026 enforcement priority; switching a bill of lading does not move the duty, it only converts a tax question into a fraud question.
5. 10 November 2026: 178 exclusions expire
178 China Section 301 product exclusions expire on 10 November 2026. Such exclusions are narrowed by ten-digit HTS code plus product description, so coverage is thin — but where one hits, the rate difference can be well into double digits. The action is specific: pull the HTS code for every SKU planned for 2027 and check it against the exclusion list and the expiry date, rather than judging at the level of “fabric”. For goods already shipped but not yet entered, check whether entry can be completed before the date.
6. Ocean freight: the Suez return is rewriting US East Coast routing
The Shanghai Containerized Freight Index stood at 3,687.35 on 30 October 2026, up 0.16% week on week and up for a fourth consecutive week. US West Coast was around USD 7,479 per 40ft and US East Coast around USD 10,199, with Panama Canal waiting times of three to six days. Meanwhile Suez is reopening fast: the PA Alliance’s MD1 returns westbound through the Red Sea on 10 November, MS2 follows on 16 November, and Gemini already runs six strings via Suez. Drewry expects canal transits to reach 80% of normal by February 2027, with the Red Sea return releasing roughly 1.6 million TEU of effective capacity during 2027.
For a US East Coast buyer that creates a genuine comparison for 2027: stay on Panama (three to six days of waiting plus canal surcharges) or route via Suez (longer distance, but restored schedules and a fading diversion surcharge). The difference in door-to-door transit may be only a few days, but the surcharge structure is not the same. Publishing two ETAs rather than one “average lead time” is both more professional and considerably safer in peak season.
7. Ten moves for the 2027 buying cycle
- Build the three-layer table. For each SKU record MFN, legacy Section 301 list rate and the new 12.5% country layer separately. Never budget on an “average” rate.
- Screen the 10 November expiries. Match ten-digit HTS codes and product descriptions against the 178 exclusions; flag affected SKUs and model the post-expiry increase.
- Audit refund eligibility. Pull entries from April 2025 to February 2026, check liquidation status and the 80-day window, and decide whether a CIT filing is required.
- Write refund ownership into the contract. Name the importer of record, the holder of the refund claim and the split under DDP.
- Add a numeric tariff-adjustment clause. A percentage threshold that reopens price, not a force majeure argument.
- Quote fabric and finished goods separately. Fabric under 5407/5903, finished blinds under 6303, hardware separately — avoid a blended customs value.
- Make origin defensible. Before considering third-country processing, confirm substantial transformation and the destination’s origin rule; do not rely on documentation alone.
- Lock Q1 space and price. The four weeks before Chinese New Year (6 February 2027) are the tightest window, and the Suez variable makes early booking more valuable than usual.
- Price two routings. For the US East Coast quote both Panama and Suez with their own transit times and surcharge notes.
- Budget for compliance. The cost of an under-valuation or misclassification case dwarfs the duty saved; the 2026 enforcement numbers make that arithmetic obvious.
8. What this changes for a Chinese mill
Once duty is restacked, the buyer’s decision variable moves from “lowest unit price” to “lowest landed cost with the least compliance exposure”. Suppliers who win the 2027 order will bring three things: a cost sheet split by HTS line, a verifiable origin and test-document set, and a pricing mechanism that shares tariff movement instead of hiding it. A mill that quotes one FOB number and answers a tariff question with “that is your country’s problem” will be screened out in the first round.
Wanbo supplies roller shade fabric, sheer, upholstery, jacquard, high-shrinkage and coated woven fabric from Keqiao, Shaoxing, on a one-stop basis, and routinely supports North American buyers with HTS classification guidance, coating and flame-retardant test documentation, and split fabric-versus-finished-goods pricing. We do not offer to “help you avoid duty” — that simply moves risk onto the customer. What we do is put the rate structure, the origin logic and the routing options on the table so the buyer can see where each dollar goes.
A closing caveat: every rate, refund milestone and freight figure here reflects public information as of early November 2026. Tariff layers and port conditions change monthly. Confirm the applicable HTS classification, Federal Register notice and carrier quotation at the time of booking; this article explains structure, it does not replace a formal entry or legal advice.
