If you source camping tents from China to sell in the US, you may have read that the tent flammability standard, CPAI-84, is “voluntary.” That’s technically accurate at the federal level — and also fairly misleading in practice. This article covers what’s actually mandatory, where, a current gap in the newer standard that regulators themselves have flagged concerns about, and what you need to verify before you order.
1. “Voluntary” federally, mandatory in seven specific states
There is no single federal law requiring tent flammability testing in the US. CPAI-84 — “A Specification for Flame-Resistant Materials Used in Camping Tentage,” originally developed by the Industrial Fabrics Association International — is a voluntary industry standard at the federal level. But it has been adopted as mandatory law in seven states: California, New York, New Jersey, Massachusetts, Louisiana, Michigan, and Minnesota. If your tents reach consumers in any of these states — which, given how national marketplace shipping works, is nearly unavoidable for most sellers — you’re subject to a real legal requirement, not a suggestion.
2. Even outside those states, major retailers make it mandatory anyway
This is the detail that makes “voluntary” a misleading word in practice: major retailers — Amazon, Walmart, Costco, and REI — independently require CPAI-84 compliance for all tents sold on their platforms nationwide, regardless of which state the buyer is in, as a way of managing their own liability exposure. In practical terms, if you’re selling through any major US marketplace, CPAI-84 compliance is required whether or not your specific customer happens to live in one of the seven states with a legal mandate.
3. What the test actually measures, and the specific pass/fail criteria
CPAI-84 evaluates tent materials in two categories — flooring material and wall/top material — under three separate conditions: as-is (original), after water leaching (submerged for 72 hours), and after accelerated weathering. Specific pass/fail thresholds apply:
- Flooring material: damage length from the test flame must not exceed a specified limit (commonly cited around 72mm) on any tested specimen, across all three conditions.
- Wall and top material: tested via vertical burn — no individual specimen’s after-flame time (how long it continues burning after the test flame is removed) may exceed 4 seconds, and the average across all specimens in a sample unit must not exceed 2 seconds.
A scope note worth knowing: CPAI-84 does not cover tent bags, pole bags, stuff sacks, or anchoring materials like ropes and guy lines — the standard is specifically about the tent’s fabric body. Sleeping bags fall under an entirely separate standard, CPAI-75 — if you’re sourcing both tents and sleeping bags, verify compliance for each separately; passing one doesn’t imply anything about the other.
4. A current regulatory tension worth knowing: the newer standard has a debated loophole
CPAI-84 is now widely considered outdated for many modern tent materials. A newer standard, ASTM F3431, follows updated test methodology aligned with Canada’s more recent CAN/CGSB-182.1 standard. But ASTM F3431 includes an option that lets a tent be “labeled out” of flammability testing requirements entirely, if it’s labeled as not intended for use with camping stoves or heaters — and CPSC staff have specifically raised concerns about this provision in the agency’s own tent flammability testing report. The takeaway: if a supplier tells you their tent is exempt from flammability testing because of a “not for use with camping stoves” label, understand this is a genuinely contested point among regulators, not a settled, uncontroversial exemption — worth erring toward requiring actual testing rather than relying on a labeling workaround that regulators themselves are questioning.
5. A scope reminder for children’s camping products
Camping and sporting equipment intended primarily for children age 12 and under is specifically excluded from the toy safety standard (ASTM F963-17) — but that doesn’t mean it’s unregulated. It still needs to meet general flammability requirements, and a consumer product generally cannot pose a “substantial risk of injury” from being extremely flammable regardless of which specific standard technically applies.
6. What to verify before you order
- Require an actual CPAI-84 (or ASTM F3431) test report, not just a supplier’s assurance that their fabric is “flame-resistant.”
- Confirm the report covers flooring and wall/top materials separately, under all three test conditions (original, leached, weathered) — a report covering only one material category or skipping the leaching/weathering steps is incomplete.
- If sourcing sleeping bags alongside tents, verify CPAI-75 compliance separately — it’s a different standard, and a tent report says nothing about sleeping bag compliance.
- Be skeptical of a supplier relying solely on a “not for use with stoves/heaters” label to skip testing, given CPSC’s own documented concerns about that provision.
The bottom line
CPAI-84 being “voluntary” at the federal level tells you almost nothing about your real-world obligation — seven states mandate it by law, and the major marketplaces you’re likely selling through mandate it platform-wide regardless. The standard itself is also in a genuine state of flux, with regulators actively questioning a labeling loophole in its intended successor. Requiring a real, current test report — not a verbal assurance or a labeling workaround — is the baseline for this category, not an extra step.
Regulatory details reflect CPAI-84, ASTM F3431, and CPSC guidance on sporting and camping equipment as of mid-2026, including CPSC’s own August 2023 tent flammability testing report. State-level mandates and platform requirements can change — verify current requirements against official state and marketplace seller policy sources before making sourcing decisions. General guidance, not legal advice.
