16 CFR Part 1610 Flammability Classifications
The Standard for the Flammability of Clothing Textiles establishes three classes of flammability based on burn time under a 45-degree angle test.
Class 1: Normal Flammability
Plain surface fabrics with burn times of 3.5 seconds or more, and raised surface fabrics (fleece, terry) with burn times greater than 7.0 seconds. Fully compliant for consumer apparel.
Class 2: Intermediate Flammability
Raised surface fabrics with burn times between 4.0 and 7.0 seconds with base fabric ignition. Requires careful evaluation and technical re-testing prior to US commercial distribution.
Class 3: Rapid & Intense Burning
Plain surface textiles burning in less than 3.5 seconds, or raised surface fabrics burning in less than 4.0 seconds. Classified as dangerously flammable and strictly prohibited from US commerce.
Statutory Flammability Exemptions (16 CFR 1610.1(d))
Certain fabrics are legally exempt from flammability testing because experience has proven they never exhibit rapid or intense burning: (1) Plain surface fabrics weighing 2.6 ounces per square yard (approx 88.2 GSM) or greater, regardless of fiber content; (2) Any fabric (plain or raised fiber surface) composed entirely of acrylic, modacrylic, nylon, olefin, polyester, or wool (or blends of these fibers alone). In such cases, the GCC cites 16 CFR 1610.1(d) as the legal basis for compliance.
GCC vs CPC vs CE Declaration of Conformity
Understanding the key differences across US and European conformity documentation requirements.
| Certificate Type | Target Product Category | Governing Agency | Testing Requirement | Customs & Border Role |
|---|---|---|---|---|
| GCC General Conformity | Adult apparel, uniforms, sportswear, promotional garments | US CPSC / Section 14(a)(1) CPSA | Test report or valid 16 CFR 1610.1(d) exemption (in-house or 3rd party lab) | Must accompany shipment or be made electronically available to US CBP upon entry |
| CPC Children's Products | Infant wear, kids apparel (age 12 and under), youth sleepwear | US CPSC / Section 14(a)(2) CPSA | Mandatory testing by a CPSC-accepted accredited third-party laboratory | Strict CBP scrutiny, lead content, tracking labels, flammability (16 CFR 1615/1616) |
| CE DoC European Union | PPE garments, heated wearables, smart tech clothing | European Commission (EU Directives) | Harmonised EN standard testing and CE Technical File documentation | Prerequisite for affixing CE mark and entering European Single Market |
The 5-Step GCC Issuance Process for US Imports
How apparel exporters and US importers generate, verify, and transmit compliant certificates of conformity.
Fabric Review
Analyze textile construction, fiber blend, and fabric weight (GSM) to determine if 16 CFR 1610.1(d) testing exemption applies.
Flammability Test
If not exempt, submit production fabric swatches to a textile testing lab for 45-degree flammability burn testing.
Draft Certificate
Populate the 7 statutory fields including product description, safety rule citations, factory details, and records custodian.
Digital Filing
Store certificate electronically on a dedicated URL or transmit PDF directly to US customs broker prior to vessel departure.
CBP Clearance
US Customs & Border Protection verifies the certificate during Automated Commercial Environment (ACE) entry processing.
Frequently Asked Questions on GCC for Apparel
Practical compliance guidance for garment exporters, US importers of record, and supply chain managers.
Who is legally responsible for issuing the GCC for imported apparel?
Under US federal law, the entity responsible for issuing the GCC is the domestic manufacturer (if made in the US) or the US Importer of Record (for products manufactured abroad). While the overseas factory typically provides the underlying laboratory flammability test data and fabric weight specifications, the US importer legally certifies and signs the document for US Customs.
Must a physical paper copy of the GCC accompany every ocean or air container?
No. The CPSC permits electronic certificates. A GCC can be satisfied if the certificate is created before shipment, made accessible through a unique web URL or electronic database provided on the commercial invoice or bill of lading, and can be promptly produced to CPSC and CBP officials within 24 hours of request.
Does a standard 100% cotton 180 GSM t-shirt require third-party flammability testing for a GCC?
No. Plain surface fabrics weighing 2.6 ounces per square yard (approximately 88.2 GSM) or greater are legally exempt from flammability testing under 16 CFR 1610.1(d)(1). A standard 180 GSM cotton jersey t-shirt is more than double this threshold weight. The GCC must still be issued, but it cites the statutory weight exemption rather than an external burn test report.
What happens if an imported apparel shipment arrives at a US port without a GCC?
Under Section 17 of the CPSA, products imported into the US that are not accompanied by a required certificate of conformity may be refused admission by US Customs and Border Protection (CBP). The shipment may be detained, held in bonded storage at the importer's expense, or subject to seizure, re-export, or civil penalties up to thousands of dollars per violation.
Does a GCC apply to children's clothing?
No. A GCC applies strictly to general non-children's consumer products (adult apparel). Children's clothing (designed or intended primarily for children 12 years of age or younger) requires a Children's Product Certificate (CPC). CPCs mandate testing by a CPSC-accepted accredited third-party laboratory and must satisfy additional rules regarding total lead content, phthalates, small parts, and children's sleepwear flammability (16 CFR 1615 and 1616).
Can one GCC cover multiple purchase orders or product styles?
A single GCC may cover multiple purchase orders or shipments provided the product identification clearly encompasses all included styles, the manufacturing dates and locations correspond, and all products are made from the exact same compliant fabric and materials. If styles use different textile blends or different factory locations, separate GCC documents must be issued.
