Disposable Nitrile Gloves Sourcing Guide: Thickness, Certification, and Grade Selection for US Buyers
Most container rejections we see at US ports of entry don't happen because the gloves are bad. They happen because the documentation doesn't match what's in the box, or because the buyer specified a grade without understanding what that grade actually requires at the factory level. A rejection at US Customs is not a customs problem — it's a documentation and inspection problem that started at the factory.
This guide covers the three decisions that determine whether your disposable nitrile gloves order clears customs, sells through, and comes back for reorder: thickness, certification, and grade.

Thickness: What the Mil Rating Actually Controls
Thickness is the spec buyers argue about most and understand least. The number on the spec sheet — typically expressed in mils (1 mil = 0.0254mm) — is a palm measurement. It tells you almost nothing about fingertip thickness, which is where most gloves fail in use and in AQL testing.
We run our dipping lines at a controlled tolerance of 0.08–0.15mm across the glove body. The fingertip is the hardest zone to hold consistent — the former geometry and dip speed both affect how compound builds up there. Factories that don't control dip speed carefully end up with fingertips 20–30% thinner than the palm, which is exactly where pinhole failures concentrate.
Here's how thickness maps to commercial application:
| Thickness (mil) | Thickness (mm) | Typical Grade | Primary Market |
|---|---|---|---|
| 2.0–2.5 mil | 0.05–0.06mm | Lightweight standard | Food service, light assembly |
| 3.0–3.5 mil | 0.08–0.09mm | Standard / exam-weight | General medical exam, dental |
| 4.0–5.0 mil | 0.10–0.13mm | Mid-weight industrial | Automotive, janitorial, lab |
| 6.0–8.0 mil | 0.15–0.20mm | Heavy industrial | Chemical handling, mechanics |
The commercial implication: thicker gloves cost more per piece and add weight per case, which affects your landed cost per carton. A buyer moving from 3.5 mil to 5.0 mil on an industrial SKU might see 15–20% higher unit cost and a meaningful freight difference at container scale. That trade-off is worth it for the right end market — but it's a margin decision, not just a spec decision.
(One thing we tell new buyers: don't over-specify thickness for food-service accounts. A 6-mil glove in a food-prep environment adds cost your customer won't pay for, and the dexterity loss creates compliance problems on the floor.)

Certification: What Each Standard Actually Covers — and What It Doesn't
This is where most sourcing mistakes happen. Buyers see "FDA" or "CE" on a product listing and assume the glove is fully compliant for their intended use. The certifications are real, but they cover specific things — and they don't cover each other.
ASTM D6319 — The US Medical Exam Standard
ASTM D6319 is the standard for nitrile rubber examination gloves for medical application in the US. It sets minimum requirements for:
- Tensile strength before and after aging
- Elongation at break (minimum 500% before aging, 400% after)
- AQL 1.5 pinhole testing per ASTM D5151
- Dimensions (length, width, thickness at palm)
What it does not cover: chemical permeation resistance, sterility, or surgical-grade barrier performance. If your buyer is in a clinical setting that requires sterile gloves, ASTM D6319 exam gloves are not the right product — that's a separate category entirely.
We hold ASTM D6319 certification across our exam-weight SKUs. The AQL 1.5 standard means we test every lot to a 1.5 acceptable quality level for pinholes — tighter than the AQL 2.5 you'll see from lower-tier suppliers. At container scale, that difference shows up in your return rate.
FDA 510(k) — Market Clearance, Not a Quality Stamp
FDA 510(k) clearance means the glove has been reviewed and cleared for sale as a medical device in the US market. It is a market access document, not a quality certification. A glove with 510(k) clearance has demonstrated substantial equivalence to a predicate device — it hasn't been independently tested for every performance parameter by the FDA.
What this means for your sourcing: 510(k) clearance is necessary if you're selling into US medical channels (hospitals, clinics, dental offices). Without it, your distributor customers in those channels can't legally stock the product. With it, you have the documentation to open those accounts.
We hold FDA 510(k) clearance on our medical-grade nitrile line. When buyers ask us for the clearance number, we provide it with the full 510(k) summary — not just a certificate image, because a certificate image alone won't satisfy a hospital procurement audit.
EN 455 — The European Medical Standard
EN 455 is the European equivalent for medical examination gloves, covering dimensions, freedom from holes, physical properties, and biological evaluation. If you're selling into EU markets or to buyers who supply both US and European accounts, EN 455 compliance matters.
EN 455 and ASTM D6319 overlap significantly in intent but differ in test methods and pass/fail thresholds. A glove that passes one doesn't automatically pass the other — we test against both independently.
CE Marking — Required for EU Market Entry
CE marking under the EU PPE Regulation (2016/425) is required for gloves sold as personal protective equipment in Europe. For medical gloves, CE marking under the EU Medical Device Regulation (MDR 2017/745) applies. These are separate regulatory pathways with different technical file requirements.
(We've seen buyers try to use a CE certificate from one regulation to satisfy requirements under the other. That's a compliance gap that surfaces during EU distributor audits — worth clarifying with your compliance team before you commit to a container.)

Grade Selection: Medical, Industrial, and Food-Contact — the Commercial Differences
"Grade" is used loosely in the market. Suppliers use it to mean different things. Here's how we define it operationally, because the grade you specify determines which production line, which compound formulation, and which documentation package your order gets.
Medical Grade
Medical-grade nitrile gloves are manufactured under ISO 13485 quality management requirements, tested to ASTM D6319 (US) or EN 455 (EU), and — for US market entry — require FDA 510(k) clearance. The compound formulation is tighter: we run lower accelerator levels on medical-grade batches, and every lot goes through AQL 1.5 pinhole testing with online detection systems before packing.
The buyer value: medical-grade documentation opens hospital, clinic, dental, and long-term care accounts. These are higher-margin channels with repeat volume and annual contract structures. The landed cost per box is higher, but so is the price your distributor customers can charge.
Industrial Grade
Industrial-grade nitrile doesn't require FDA clearance or EN 455 compliance, but it still needs to perform. The relevant standard for US industrial gloves is ASTM D6978 (chemical permeation) for chemical-handling applications, and buyers in automotive, janitorial, and manufacturing supply often ask for ISO 9001 certification as a baseline quality signal.
We produce industrial-grade nitrile at 4.0–8.0 mil depending on application. The compound is formulated for puncture resistance and chemical splash resistance rather than the elongation and tensile properties prioritized in medical-grade. (The two formulations are genuinely different — you can't just run a thicker version of a medical compound and call it industrial-grade. The performance profile is different.)
Industrial accounts — safety distributors, MRO suppliers, janitorial wholesalers — typically buy on price per case more aggressively than medical accounts. Margin is thinner, but volume is higher and reorder cycles are predictable.
Food-Contact Grade
Food-contact nitrile gloves need to comply with FDA 21 CFR 177.2600 (rubber articles intended for repeated use) or equivalent food-contact regulations in the destination market. This is a separate compliance pathway from the medical device regulations — a glove with FDA 510(k) medical clearance is not automatically compliant for food contact, and vice versa.
We produce powder-free food-contact nitrile in 3.0–4.0 mil. The powder-free requirement is non-negotiable for food-contact applications — powdered gloves are banned in US food processing environments under FDA regulations that took effect in 2017.
| Grade | Key Standard (US) | Typical Thickness | Primary Buyer Channel |
|---|---|---|---|
| Medical exam | ASTM D6319 + FDA 510(k) | 3.0–4.0 mil | Hospitals, clinics, dental, LTC |
| Industrial | ISO 9001 + ASTM D6978 (chemical) | 4.0–8.0 mil | Safety distributors, MRO, automotive |
| Food-contact | FDA 21 CFR 177.2600 | 3.0–4.0 mil | Food processing, food service |

The Sourcing Trap: What Spec Sheets Don't Tell You
A spec sheet from a supplier shows you what the glove is supposed to be. It doesn't show you what the glove actually is when it leaves the factory. This is the gap where most import problems originate.
Three things to verify before a container ships:
1. Request the actual test report, not just the certificate. A certificate shows that a glove model passed testing at some point. A test report shows the lot number, test date, actual measured values, and the testing lab. For ASTM D6319 compliance, you want to see tensile strength, elongation, and AQL pinhole results for the specific production lot in your container.
2. Confirm the AQL level in the test report. AQL 1.5 and AQL 2.5 are not the same. A supplier quoting "AQL tested" without specifying the level is almost certainly running AQL 2.5 or higher. At container scale, the difference in defect rate is meaningful — and it's your customer who finds the defective gloves, not the factory.
3. Check that the 510(k) clearance number matches the product in the container. We've seen cases where a supplier holds 510(k) clearance on one SKU and ships a different SKU under the same documentation. The clearance number is specific to a device description — if the glove in the box doesn't match the cleared device description, the documentation is invalid. Ask for the 510(k) summary document and compare the device description to your purchase order spec.
We run 100% AQL 1.5 inspection with online pinhole detection on every production run. Pre-shipment inspection reports are available for every container — not on request, as standard practice. That's the documentation package your customs broker and your buyers' compliance teams actually need.

Powder-Free, Accelerator-Free, and Textured: Spec Variants That Affect Your SKU Mix
Three product variants come up in almost every sourcing conversation, and each one affects a different part of your market access.
Powder-free is the baseline for US medical and food-contact channels. Powdered nitrile gloves are banned for surgical and patient examination use in the US (FDA final rule, 2017). If you're building a US-focused SKU mix, powder-free is not a premium option — it's the standard.
Accelerator-free (also called low-protein or Type IV allergy-safe) is a growing requirement in European medical markets and increasingly in US hospital systems with latex-sensitivity protocols. Accelerator-free nitrile uses a different vulcanization chemistry that eliminates thiuram and carbamate accelerators — the compounds associated with Type IV hypersensitivity reactions. We produce accelerator-free variants from the same facility; the compound formulation is different, and the production run requires a line flush between standard and accelerator-free batches to prevent cross-contamination.
Textured fingertip is a grip enhancement that matters in surgical, dental, and precision assembly applications. The texture is formed during the dipping process by a controlled surface treatment on the former — it's not a post-production coating. Buyers targeting dental or surgical instrument handling accounts should specify textured fingertip; it's a feature those buyers actively look for and will pay a modest premium for.
(Accelerator-free has grown significantly for us in European accounts over the past few years. If you're building a line for EU distribution, it's worth including at least one accelerator-free SKU from the start rather than adding it later when a hospital tender requires it.)

What US Buyers Get Wrong When Sourcing Offshore
The most common mistake is treating certification as a binary — either the supplier has it or they don't. In practice, certification has scope. A supplier might hold FDA 510(k) clearance on a 3.5 mil powder-free exam glove and not on their 6 mil industrial SKU. They might hold ASTM D6319 certification on one color and not another. The clearance is specific to the device as described in the 510(k) submission.
The second mistake is not specifying AQL level in the purchase order. If your PO says "AQL tested" without a level, the supplier will default to whatever they run — and that may be AQL 2.5 or higher. Write AQL 1.5 into your PO if that's what you need.
The third mistake is conflating ISO 9001 with product certification. ISO 9001:2015 is a quality management system standard — it certifies the factory's processes, not the product's performance. A factory can hold ISO 9001 and still produce gloves that fail ASTM D6319. The two certifications answer different questions.
We hold ISO 9001:2015, CE, EN 455, ASTM D6319, and FDA 510(k) across our product range. When you request a quote, we send the full documentation package with the quotation — not after you've committed to an order.

Frequently Asked Questions
What thickness of nitrile glove do I need for medical exam use in the US?
For ASTM D6319 compliance, the minimum palm thickness is 0.05mm (approximately 2 mil), but most US medical buyers specify 3.0–4.0 mil (0.08–0.10mm) for exam-weight gloves. The practical reason: thinner gloves at the minimum spec have less margin for thickness variation across the glove body, which increases AQL failure risk. Most hospital and clinic procurement specs land at 3.5 mil as a balance between dexterity and barrier reliability.
Does FDA 510(k) clearance cover all sizes and colors of a glove model?
No. The 510(k) clearance is specific to the device description in the submission, which typically includes the glove model, material, and intended use. Size variants (S/M/L/XL) are generally covered under one clearance if the device description includes them. Color variants may or may not be covered depending on how the original submission was written. Ask your supplier for the 510(k) summary document and check the device description — don't assume coverage extends to every SKU in their catalog.
What's the difference between AQL 1.5 and AQL 2.5 in practical terms?
AQL 1.5 means the acceptable quality level for pinholes is 1.5 defects per 100 units. AQL 2.5 allows up to 2.5 defects per 100 units. At a 10,000-box container, that's the difference between accepting up to 150 defective boxes versus up to 250. For medical channels where a single defective glove creates a liability event, AQL 1.5 is the standard to specify. For general industrial use, AQL 2.5 is common and acceptable.
Can I source medical-grade and industrial-grade nitrile from the same factory?
Yes, and it's often preferable — you get consistent documentation practices, a single supplier relationship, and the ability to consolidate container loads across grades. The key is confirming that the factory runs the two grades under separate quality management protocols, not just different thickness specs. Medical-grade production requires ISO 13485-aligned controls that don't apply to industrial production. We run both grades from the same 18,000 m² facility under separate QC protocols.
What documents should I request before a container ships?
At minimum: the lot-specific test report (tensile, elongation, AQL pinhole results), the 510(k) clearance summary (for medical-grade), the packing list with lot numbers, and the pre-shipment inspection report. If you're importing into a state with specific labeling requirements (California Prop 65, for example), confirm labeling compliance before the container is packed — relabeling at the destination warehouse is expensive and delays your customer's order.

Grade and Spec Selection: A Practical Decision Path
If you're building a US-focused nitrile glove SKU mix from scratch, here's how we'd frame the decision:
Start with your primary channel. Medical channels require FDA 510(k) and ASTM D6319 — that's non-negotiable. Industrial channels need ISO 9001 as a baseline and ASTM D6978 if chemical resistance is a selling point. Food-contact channels need FDA 21 CFR 177.2600 compliance and powder-free construction.
Then set your thickness by end-market, not by what sounds impressive on a spec sheet. A 3.5 mil exam glove is the right product for a dental office. A 6 mil glove in that same account is over-specified and will cost your distributor customer margin they can't recover.
Finally, confirm AQL level and documentation package before you issue a PO. The documentation is what protects your import clearance, your customer relationships, and your ability to reorder without surprises.
We've been running this factory since 2007 — 8 automated dipping lines, 1.2 billion pieces annual capacity, and a compliance team that has handled FDA and ASTM documentation for US buyers across every major distribution channel. If you're building a new SKU line or switching suppliers, the fastest way to get the right spec is to send us your target channel and volume. We'll match the grade, thickness, and documentation package to what your buyers actually need.
