TSCA Import Certification: Positive, Negative and the Articles That Now Need One

“Articles never need TSCA” is one of the most durable assumptions in import compliance, and one of the most expensive to hold in 2026. A container of dining chairs, kitchen cabinets or MDF shelving needs a TSCA import certification on every line containing regulated composite wood, and has since 22 March 2019. A shipment of PVC-containing goods with phenol, isopropylated phosphate (PIP (3:1)) faces a distribution ban after 31 October 2026, unless the part falls under one of the rule’s exclusions (such as wire harnesses and circuit boards) or a later phase-in date (such as 2034 for parts in new electronic equipment). And the PFAS reporting obligation that was supposed to open in April 2026 has moved, with the exemption most article importers are counting on still only proposed.

Under 19 CFR 12.121, an importer of a chemical substance, mixture or article subject to a TSCA rule must certify before release either that the shipment complies with TSCA (a positive certification) or that it is not subject to TSCA (a negative certification). Getting the direction wrong is not a technicality: a negative certification on goods that are subject to a rule is a false statement on the entry. This guide covers which certification applies, how composite wood and PIP (3:1) change the answer for furniture and electronics importers, and where PFAS reporting stands. Rules checked against the eCFR and Federal Register as of September 2026.

Positive vs Negative Certification

The two statements answer different questions. A positive certification says the shipment is subject to TSCA and complies with all applicable rules and orders in effect. A negative certification says the shipment is not subject to TSCA at all, for example a food, drug, cosmetic, pesticide or other product regulated under a different statute and excluded from the TSCA definition of a chemical substance. Under 19 CFR 12.121(a)(2) it is required when an excluded chemical is not clearly identified as such; when it is clearly identified, such as a pesticide entered with an EPA Notice of Arrival, a disclaim may apply instead.

In ACE the certification is transmitted as part of the entry. CBP implementation guidance for the TSCA message set uses program code TS1, with EP4 for a positive certification and EP5 for a negative one. The certification is made by the importer, or by its broker when the importer has authorized the broker to certify on its behalf through the customs power of attorney and supporting instructions. Either way the legal responsibility stays with the importer of record.

The practical rule is simple to state and harder to apply: if any TSCA rule reaches the product, the answer is positive, and the importer must be able to show compliance with that rule. Negative certifications belong to products that TSCA does not reach, not to products the importer believes are low risk.

Articles vs Chemical Substances

TSCA import certification was built around chemical substances and mixtures: drums of solvent, bags of pigment, totes of resin. For those, the question is always which certification to make, and the answer turns on whether each substance is on the TSCA Inventory or otherwise covered, and whether any rule or order applies to it. Importers of these products, including many cosmetics and chemical logistics accounts, usually have the process in place.

Articles are different. An article is a manufactured item formed to a specific shape or design, whose end use depends on that shape or design and whose chemical composition does not change during use (19 CFR 12.120). For most articles no certification is required at all. The exception is written into specific rules: when EPA issues a rule that reaches articles, the importer of those articles must certify compliance. Composite wood is the largest such rule by import volume, and the persistent, bioaccumulative and toxic chemical rules, including PIP (3:1), are the reason electronics and cable importers now need to look at articles too.

That is why the “articles never need TSCA” assumption breaks. It was mostly true for years and became false one rule at a time. A compliance file that still treats all finished goods as outside TSCA has not caught up with the rules issued since 2016.

Composite Wood (Title VI) Certification for Furniture and Cabinets

TSCA Title VI, implemented at 40 CFR 770, sets formaldehyde emission standards for hardwood plywood, medium-density fiberboard and particleboard, and for finished goods that contain them. Under 40 CFR 770.30(d), importers of articles containing regulated composite wood must make a positive TSCA import certification, a requirement that has applied since 22 March 2019. It covers dining tables, cabinets, bathroom vanities, bookcases, flooring with composite cores and a long list of hotel and office furniture.

Three documents make the certification defensible. The panels or finished goods must be labeled as TSCA Title VI compliant under 40 CFR 770.45. The importer must hold records showing that the composite wood came from certified sources, including supplier statements that trace back to the panel producer. And those records must be kept for three years. An EP4 on the entry without that file is a certification the importer cannot support if EPA or CBP asks.

The weak point is the supply chain behind the furniture factory. A factory that buys panels from several mills, or switches mills mid-season to manage cost, can break the documentation trail without changing anything visible on the product. Importers of furniture and cabinetry, many of whom are also managing lumber tariffs on the same goods, should collect panel-level supplier statements per purchase order, not once per supplier relationship.

EPA proposed updating the standards incorporated into the Title VI rule at 91 FR 6161 on 11 February 2026. That is a proposal, not a change in the current obligation, and the existing certification and labeling requirements continue to apply.

PIP (3:1) Distribution Ban After October 31, 2026

PIP (3:1) is a flame retardant and plasticizer used widely in PVC, which puts it in wire and cable insulation, electronics, appliance components and some industrial equipment. EPA’s rule at 40 CFR 751.407 prohibits the distribution in commerce of articles containing PIP (3:1) after 31 October 2026. Specific parts and uses have later dates, from 2029 to 2054 or the end of equipment service life, and some uses, such as wire harnesses and circuit boards, are excluded outright. The carve-out that applies depends on the exact part and end use listed in the rule.

For importers the risk sits in inventory rather than at the border. Goods already landed and sitting in a distribution center are still subject to the prohibition once the date passes, so the question is not only what ships next month but what is on the shelf on 1 November. Importers of electrical and electronic goods should request written supplier declarations on PIP (3:1) content now, identify which SKUs rely on a part-specific extension, and align the TSCA import certification on each entry with what the declarations show.

Supplier declarations are only as good as the bill of materials behind them. Cable harnesses and PVC components are commonly sourced from sub-suppliers two or three tiers below the assembler, so the request needs to reach the component level to be meaningful.

PFAS Section 8(a)(7) Reporting: Where It Stands

The TSCA section 8(a)(7) rule requires one-time reporting on PFAS manufactured, including imported, in past years. The start date of 13 April 2026 no longer applies. Under the rule published at 91 FR 18786 on 13 April 2026, the submission period now opens on 31 January 2027, or 60 days after EPA’s forthcoming final rule on the reporting scope, whichever is earlier.

The change importers of articles care most about is still pending. EPA has proposed an exemption for PFAS imported as part of an article (90 FR 50923, 13 November 2025), but it is a proposal only. Until a final rule is published, article importers cannot treat the exemption as settled, and the safe planning assumption is that article imports may be in scope when the window opens.

The preparation work is the same either way: build an inventory of imported products that may contain PFAS, by SKU and by year, and identify which suppliers can document PFAS content. If the article exemption is finalized, the inventory narrows to chemical imports. If it is not, the inventory becomes the reporting base. Doing the work now avoids compressing it into the weeks before the window opens.

Running TSCA Certification as a Line-Level Control

TSCA certification problems are rarely caused by not knowing the rule. They come from the certification being set once per importer or once per product family and never revisited as the product mix changes. A furniture importer adds a line with an MDF back panel; an electronics importer changes cable suppliers; a chemical distributor starts carrying a product that falls outside TSCA. Each change can flip the correct answer on specific lines.

The control that works is line-level: each product record carries its TSCA status, the basis for it and the supporting document, and the broker transmits the certification from that record rather than from a default. HTS classification helps flag candidates, since composite wood furniture and PVC-insulated cable cluster in predictable chapters, but the HTS code alone does not decide TSCA status. The product content does.

The same control belongs inside the wider trade compliance management program alongside other agency requirements, from US import licenses to partner government agency data. A licensed customs brokerage can transmit the right code on every line only if the importer’s product data carries the answer, and a customs compliance platform that stores those attributes per SKU turns an annual scramble into a routine field check.
