Rug flammability for U.S. imports is governed by two CPSC standards defined by size: 16 CFR 1630 for large carpets and rugs and 16 CFR 1631 for small ones. As written, the two size definitions do not cover every rug. Both are certifiable rules, both sit on CPSC’s general and children’s certificate lists, and carpets and rugs are on CPSC’s 1USG screening list. Since July 8, 2026, every rug entry in scope has to carry certificate data into ACE through the CPSC PGA Message Set.

The two standards look alike but behave differently at the point of sale: a large rug that fails cannot be sold, while a small rug that fails can still be sold if it carries a permanent FLAMMABLE label. One-of-a-kind rugs add a third path that is often misfiled. This piece covers those mechanics for rug importers. The general CPSC import framework is in our CPSC compliance guide.

1630 vs 1631: Which Rug Flammability Standard Applies

16 CFR 1630 applies to large carpets and rugs, defined as those with one dimension greater than 6 feet and a surface area greater than 24 square feet. Carpet squares count toward that definition when they are assembled into a larger area. 16 CFR 1631 applies to small carpets and rugs, defined as those with no dimension greater than 6 feet and an area not greater than 24 square feet. Both parts cover mats and hides with natural or synthetic fibers within their size definitions; resilient floor coverings are excluded.

Each definition has two cumulative conditions, and runners are where importers misread them. The two definitions do not cover every size. A runner with one side over 6 feet but 24 square feet or less, or a rug over 24 square feet with no side longer than 6 feet, meets neither definition as written, so the standard to cite for those sizes should be confirmed with CPSC before certifying. The standard follows the physical dimensions, not the product name or the HTS subheading.

The Small Rug FLAMMABLE Label Option

The practical difference between the two parts is what happens on a failure. Large rugs under 1630 must pass. Small rugs under 1631 that fail the standard may still be sold, provided they are permanently labeled under 16 CFR 1631.5 with the prescribed warning, which begins: FLAMMABLE (FAILS U.S. DEPARTMENT OF COMMERCE STANDARD FF 2-70). The full label text is set out in 1631.5.

The label option does not remove the certificate. A labeled small rug is still a product subject to 1631, so the certificate still cites 1631 and still rests on testing. What changes is the compliance outcome: the rug complies by carrying the label rather than by passing.

Rugs given a flame-retardant treatment carry a separate marking duty: FR-treated rugs need the T mark. A treated rug whose label or mark is missing is a compliance defect even if the rug itself would pass.

The one-product-per-certificate rule applies to rugs as to every certified product: a change in design, manufacturing process or location, or component or material source makes a rug materially different and requires its own certificate. Size variants of the same construction need care, because a size change can move a design from 1631 to 1630, or into a size neither definition covers, and change which rule the certificate cites.

One-of-a-Kind Rugs: A Testing Exclusion, Not a Disclaim

Antique rugs, Oriental rugs and hides that qualify as one of a kind are the rug category most easily misfiled at entry. The instinct is to file them as exempt, with no certificate. That is wrong. The one-of-a-kind provision is a testing exclusion under 1630.2(b) and 1631.2(b), not a disclaim, and a certificate is still required.

The mechanics follow CPSC’s code structure. The certificate cites the rule (1630 or 1631), and instead of test data for that rule, the one-of-a-kind status is entered as a testing exclusion code. In the Full message set under CATAIR v2.5, that means the PG19 entity role NOL (no lab testing) with the exclusion code in PG60. A testing exclusion claimed without the underlying rule citation is one of the predictable failure points that follow from the rule and the implementation guide.

For a dealer importing one-of-a-kind pieces individually, the Full message set is the natural fit, since each piece is its own product. The certificate still needs the seven data elements required by 16 CFR 1110.11, including the date and place of manufacture to at least month and year, which for older pieces means the importer needs a documented basis for the date it states.

Testing Basis for Rug Certificates

Which lab can test depends on the certificate type. Most rugs are general-use products certified on a General Certificate of Conformity. A GCC can rest on a test of each product or a reasonable testing program, and testing by any qualified lab, including first-party testing at the mill, is acceptable. The certificate must still name each lab or party whose testing it relies on, with name, address, email and phone, and give the most recent test date.

A rug designed or intended primarily for children 12 or younger is a children’s product and goes on a Children’s Product Certificate. That changes three things. Testing must come from a CPSC-accepted third-party lab, entered in the Full message set with role ITL and its mandatory 4-digit Lab ID. Periodic third-party testing applies under 16 CFR 1107.21. And other children’s rules come into play, including total lead content, where CPSC’s textile lead determination at 1500.91(d)(7) is entered as an exclusion code for the textile while any non-textile components still need their own basis.

Component testing under 16 CFR part 1109 can support either certificate, with due care and traceability. Component certificates are never eFiled, but the testing relied on must appear on the finished rug’s certificate.

GCC and eFiling for Rugs

At entry the importer transmits the Full PGA Message Set, with every certificate data element, or the Reference PGA Message Set, which carries the Certifier ID, Product ID and Version ID of a certificate already certified in CPSC’s Product Registry. For a mill program with recurring designs, the Reference set is the practical route: CPSC estimates 15.3 seconds per Reference filing against 4.75 minutes per Full filing (90 FR 1800). The Registry supports bulk CSV upload and an API, and a certified record can be edited only within 48 hours before a change requires a new Version ID. Our CPSC certificate eFiling service runs both paths for rug programs.

Carpets and rugs are one of the categories on CPSC’s September 2026 HTS list and on its 1USG list. Flagged lines return an Under Review status. The CPSC clock is 8 business hours for ocean freight, extended to 16 with added risk factors, and 4 or 8 for air and truck, counted 8am to 4pm port time. If CPSC takes no action, a May Proceed issues automatically. Correct HTS classification matters here because it decides which lines CPSC flags.

Methods can be mixed within one entry, so a container with large rugs on Reference sets and antique pieces on Full sets carrying exclusion codes is a normal filing, provided each HTS line resolves to one method. A licensed customs brokerage team can map both paths, but the certificate content remains the importer’s responsibility under 16 CFR 1110.15.

Zone inventory and timing

Rugs held in a foreign-trade zone become subject to eFiling when entered for consumption or warehousing from the zone on or after January 8, 2027. CPSC requires the actual certificate of the goods withdrawn, not the latest certificate for the design, so zone records need certificate versions attached to specific receipts.

Where Rug Entries Break

These risks follow from the rule and CATAIR; CPSC has published no hold or rejection statistics since eFiling began on July 8, 2026.

• A one-of-a-kind rug disclaimed instead of certified with a testing exclusion code.
• A runner or square certified to 1630 or 1631 without checking both size conditions, including sizes that meet neither definition as written.
• A small rug that failed 1631 shipped without the permanent 1631.5 FLAMMABLE label.
• An FR-treated rug missing its T mark.
• One certificate stretched across designs from different mills or with different material sources.
• A children’s rug certified on a GCC, or on a CPC without a CPSC-accepted lab and Lab ID.
• Manufacture date and place on the certificate not matching the mill on the commercial invoice.

Exposure when the certificate is missing or wrong

ACE does not reject entries for missing CPSC data (CSMS #69382435, July 29, 2026), and CPSC has said it does not currently intend to ask CBP to deny entry solely for failure to eFile. Missing or false data still raises the shipment’s risk score. Goods not accompanied by a required certificate, or accompanied by a false one, can be refused admission under 15 U.S.C. 2066(a)(2) and destroyed unless export is approved and executed within 90 days, at the owner’s or consignee’s cost. Civil penalty maxima stand at $120,000 per violation and $17,150,000 for a related series (86 FR 68244).

A SKU-level record of size, construction, mill, treatment, test basis and certificate version, kept in a trade compliance management system, prevents most of these mismatches before the booking. Our customs compliance platform carries certificate identifiers alongside entry lines so the broker can check them before transmission.

Frequently Asked Questions

The cosmetic vs drug question decides which FDA program a beauty import enters under, and the answer is often not the one the brand expects. A tinted moisturizer with SPF 30 looks like a cosmetic on the shelf, but FDA regulates the sunscreen claim as an over-the-counter drug. The same applies to antiperspirants and anti-dandruff shampoos. A product listed under the Modernization of Cosmetics Regulation Act (MoCRA) can still be held at the port because it was entered as a cosmetic when FDA reads it as a drug, and for a drug-cosmetic the MoCRA listing is the wrong filing altogether.

This guide is for trade and compliance teams at beauty brands, K-beauty and J-beauty importers and retailer private-label programs. It covers the intended-use test, what MoCRA requires on the cosmetic side, the OTC monograph rules for cosmetic-drug products, the sunscreen monograph order announced on September 11, 2026, and how the ACE entry data differs between the two routes.

The Intended-Use Test That Separates Cosmetics From Drugs

FDA classifies a personal care product by what it is intended to do, and it reads intended use from the label, the claims and the way the product is marketed. A product that only cleanses, beautifies or changes appearance is a cosmetic. A product intended to prevent sunburn, reduce perspiration or control dandruff is a drug, even when it is sold on the same shelf, in the same packaging style, by the same brand.

Many products are both. A moisturizer with SPF is a cosmetic for its moisturizing function and a drug for its sun-protection function. Because it is subject to the drug requirements, section 613 of the FD&C Act exempts it from MoCRA registration, listing, adverse event reporting and safety substantiation, and it is listed with FDA as a drug instead. Its label still has to meet the drug labeling rules and the general cosmetic adulteration and misbranding provisions. In practice the drug side governs the import, because drug requirements at entry are the stricter ones and FDA will not release a drug product that lacks them.

Claims move products across the line in both directions. Removing a drug claim from a label can return a product to cosmetic status, but only if the claim disappears everywhere the product is sold, including marketplace listings and translated inserts. A Korean or Japanese product that is marketed at home with sun-protection or therapeutic claims keeps those claims in FDA’s eyes if the English labeling or US listing repeats them.

MoCRA Registration and Listing on the Cosmetic Side

MoCRA added sections 604 to 614 to Chapter VI of the Federal Food, Drug, and Cosmetic Act and created registration and listing duties for cosmetics that did not exist before. Facilities that manufacture or process cosmetics for the US market register with FDA, and the responsible person lists each product, including its ingredients. FDA began enforcing registration and listing on July 1, 2024.

The obligations that matter for an import program are these:

Exemptions and open rulemaking

Small businesses with average US cosmetic sales under $1,000,000 over the prior three years, adjusted for inflation, are exempt from registration and listing, but the exemption does not cover eye-area, injected, internal-use or long-wear appearance-altering products. FDA can suspend a facility registration where a product has a reasonable probability of causing serious adverse health consequences.

Several MoCRA rules are still pending. FDA withdrew its proposed talc asbestos-testing rule on November 28, 2025, and no proposed rule on cosmetic good manufacturing practice or fragrance-allergen labeling had been published in the Federal Register as of September 23, 2026. Importers should expect further rulemaking but should not build programs around proposals that do not yet exist.

• Facility registration, renewed every two years from the facility’s own initial registration date rather than in a fixed national window. New facilities register within 60 days of starting operations, and changes are updated within 60 days.
• Product listing by the responsible person, with new products listed within 120 days of marketing and listings updated annually.
• Serious adverse event reports submitted to FDA within 15 business days.
• Safety substantiation records kept for each product.
• A US agent for each foreign facility, with a limited role covering FDA communications, product questions and inspection scheduling.
• Submissions made through FDA’s Cosmetics Direct portal.

OTC Monograph Drugs: SPF, Antiperspirant and Anti-Dandruff

Sunscreens, antiperspirants and anti-dandruff products are marketed in the US under OTC monographs. A monograph fixes the active ingredients, strengths and labeling a product may use, and a cosmetic-drug product that relies on it is a drug for every regulatory purpose, including import.

That drug status carries requirements a cosmetic does not have. The foreign facility making the product must hold drug establishment registration before the product is imported, under 21 CFR 207.21(b), with an annual review each year between October 1 and December 31 and a single US agent. The product must be listed as a drug and carry a National Drug Code (NDC). And the formula and label must comply with the applicable OTC monograph. The facility also owes the annual OTC monograph drug facility fee; FDA treats OTC monograph drugs from a facility in arrears as misbranded.

A MoCRA registration does none of this. This is where beauty import programs go wrong: the brand registers its cosmetic facility, lists its whole range in Cosmetics Direct, SPF line included, and assumes it is covered. It is not. An SPF product is exempt from MoCRA listing and must instead be covered by drug establishment registration and a drug listing with an NDC, which are separate filings with separate data that FDA checks at entry.

Pending change to foreign drug registration

FDA published a proposed rule on foreign drug establishment registration on July 13, 2026 (91 FR 42888). It is a proposal, not a final rule, and the current registration requirements continue to apply until FDA finalizes any change.

The September 11, 2026 Sunscreen Monograph Order

FDA announced final order OTC000008-1 in the Federal Register on September 11, 2026 (91 FR 57892). The order removes two active ingredients, PABA (aminobenzoic acid) and trolamine salicylate, from the sunscreen monograph. A sunscreen that relies on either ingredient no longer fits the monograph and cannot be marketed on that basis.

For importers, the order turns into a formula screen. Every SPF product in the program, including tinted moisturizers, foundations, lip products and sprays that carry a sunscreen claim, should be checked against its ingredient list for these two actives. The check matters most for private-label and imported lines whose formulas were developed for other markets, where the ingredient decisions were made against a different rulebook.

Entry Data Differences Between Cosmetic and OTC Drug Lines

The cosmetic vs drug decision changes the FDA message set the broker transmits in ACE. The two routes use different programs and different mandatory data, and FDA’s screening compares what is declared against its registration databases.

On the cosmetic route, FDA’s March 10, 2026 ACE guidance still treats the cosmetic registration number (the COS Affirmation of Compliance) as optional, even though MoCRA registration is a legal obligation. Transmitting it anyway helps FDA match the shipment to the registered facility. On the OTC drug route, the drug registration (REG) and drug listing (DLS) codes are mandatory, and FDA states that an entry can be detained when the declared drug manufacturer cannot be found in its drug registration database.

What a refusal means for a drug line

Drug lines carry harsher outcomes when they go wrong. A drug from an unregistered or unlisted foreign establishment faces detention and refusal under section 801(a). FDA’s Regulatory Procedures Manual directs its staff not to permit relabeling as a way to bring a drug detained on a new drug charge into compliance, so a mislabeled SPF product may have no path to release. Refused goods must be exported or destroyed within 90 days, and FDA may destroy refused drugs valued at $2,500 or less without offering export.

Triage Before the Container Ships

The fix is a product-by-product triage run when the assortment is set, not when the vessel is at sea. Each SKU gets a route and a document set before booking.

How CargoTrans supports beauty importers

CargoTrans runs cosmetic and OTC drug entries through its customs brokerage team and supports route triage as part of trade compliance management. Warehousing, distribution and sector-specific logistics for beauty and chemical products are covered on our cosmetics and chemical distributors page. Foreign brands acting as their own importer of record should also review the rules for a non-resident importer, and importers sourcing from Seoul or Tokyo can check current duty exposure in our Korea tariffs and Japan tariffs guides.

• Sort every SKU by claim: cosmetic only, or cosmetic plus a sunscreen, antiperspirant or anti-dandruff claim.
• For cosmetic lines, confirm the MoCRA facility registration, the product listing and the foreign facility’s US agent, and send the registration number with the entry.
• For drug lines, confirm drug establishment registration, the NDC listing and the monograph fit before the PO is released.
• Screen every SPF formula for PABA and trolamine salicylate following the September 11, 2026 order.
• Check the US listing and translated labels for claims that move a cosmetic into drug territory.
