An IP68 dry bag is both dust-tight (6) and rated for continuous submersion (8), the highest common consumer rating. It protects against both fine particles and sustained water exposure, making it ideal for electronics.
People searching for "ip68 dry bag" usually want a direct, practical answer - and this page delivers one. This guide explains IP68 dry bag ratings and how waterproofing is actually tested, so you can read a spec sheet and a test report with confidence instead of trusting a label.
Two digits, two threats
The 6 means complete protection against dust, and the 8 means submersion protection under stated conditions. Together they cover the beach, trail and waterline.
IP68 vs IPX8
IP68 adds a tested dust-tight seal, while IPX8 only verifies water. For sandy or dusty environments, the dust rating adds real value.
Checking the claim
Confirm the test depth, duration and standard, and ask for the test report. A true IP68 dry bag should name its test conditions, not just print the digits.
Rating vs real-world performance
A IP68 dry bag rating is a controlled test, not a promise for every situation. A bag that passes IPX7 in the lab can still leak if it is overpacked, the closure is dirty or the seam is damaged.
Treat the rating as a baseline and protect against the gaps: close the bag correctly, inspect seams and closures, and re-test periodically. Real-world care extends what any rating delivers.
What IP68 actually means
IP68 combines a dust-tight rating (6) with an immersion rating (8). The dust digit means the bag is fully protected against dust ingress, which is useful for beach and desert use.
The 8 still does not specify a universal depth. A IP68 dry bag labeled IP68 must state its test depth and duration to be meaningful, just like an IPX8 rating.
What rating you actually need
For kayaking, rafting and any chance of submersion, a IP68 dry bag should meet IPX7 or IPX8. For casual beach, travel or commuting where only splashes and rain occur, IPX6-level protection may be enough.
Match the rating to the real risk. Paying for IPX8 in a beach tote is unnecessary, while trusting an IPX6 bag in a kayak hatch is risky. The right rating is the one that matches your water exposure.
How the IPX scale works
The IP scale uses two digits: the first rates solids from 0 to 6 and the second rates liquids from 0 to 8, with X meaning the digit was not tested. A IP68 dry bag only concerns the liquid (second) digit.
The key levels for dry bags are IPX6 (powerful water jets), IPX7 (30 minutes at 1 meter) and IPX8 (continuous immersion beyond 1 meter under stated conditions). Higher is not automatically better without the test context.
What to ask a supplier about testing
Before you trust a IP68 dry bag, ask for the test report, the standard used, the depth and duration for any IPX8 claim, and the production batch sampling plan.
Written answers are better than verbal ones. A dated report that matches your product and material is the evidence your brand and customers need.
Reading a test report
A credible IP68 dry bag test report states the standard, the test conditions, the sample and the result. Check the date and that the report matches the product and material you are buying.
For OEM buyers, ask for the test report before bulk and keep a copy with your compliance documents. A dated, matching report protects both your brand and your customers.

How the IP rating digits actually work
When buyers want to see this on a real line, our parent company opens its Quanzhou factory for a live walkthrough.Waterproof claims only mean something once you decode the rating system. an IP68-rated dry bag uses the Ingress Protection code, which is two digits after the letters IP: the first rates protection against solids and dust (0 to 6), and the second rates protection against liquids (0 to 8). An X means that digit was not tested. So IPX7 means dust was not rated but liquid protection was tested to immersion; IP68 adds dust-tight sealing on top of deeper immersion.
Critically, the second digit 7 and 8 are not universal depths. IPX7 means 1 metre of fresh water for 30 minutes. IPX8 means continuous immersion beyond 1 metre, but the exact depth and time are set by the manufacturer and must be stated on the product - two bags both labelled IPX8 can perform very differently if one specifies 3 m and the other 10 m.
Rating | Protection | Practical meaning |
|---|---|---|
IPX4 | Splashes | Light rain only |
IPX6 | Powerful jets | Rough spray, whitewater |
IPX7 | 1 m / 30 min | Short immersion, drops in water |
IPX8 | Beyond 1 m | Extended submersion, diving |
Why a roll-top still sets the real limit
Here is the honest nuance buyers miss: the film may be IPX8-rated, but the closure is often the weakest link. A roll-top bag rated IPX7 survives a dip because the folded roll creates its own water barrier, but it is not a pressure-sealed diving container. True continuous submersion at depth needs a watertight zipper, a gasketed lid or a sealed dry box, not a rolled flap. When you compare products, look past the label to the closure type. A roll-top rated IPX7 is perfect for kayak drops, boat spray and rain; it is not the same as a phone dry box rated IPX8 to 10 m. Matching the rating to the actual activity prevents both overpaying and under-protecting your gear.
Dust, the first digit, and IP6X
The first digit is easy to ignore on a dry bag, but it matters for beach, desert and dusty trail use. A 6 means dust-tight: no dust enters at all. A dry bag with an open roll-top will let fine sand and dust in around the opening even if it keeps water out, so for photographers and electronics users the sealed-zipper or gasketed designs earn the dust rating while an open roll-top earns mainly the liquid rating. This is exactly why IP68 (dust-tight plus deep immersion) is reserved for sealed-lid products, while most roll-top dry bags are marketed as IPX7 or IPX8. Comparing an IP68 hard case against an IPX7 roll-top on "rating" alone misses the closure physics that actually governs your gear.
Reading a spec sheet like a buyer
When a supplier sends a spec sheet, verify three things: the rating digits, the stated depth/time, and the test date. If the sheet says merely "waterproof" with no IP digits, treat it as marketing. If it says IPX8 with no depth, ask for the manufacturer-specified immersion conditions. If the test report is undated or references a different SKU, request a fresh one for your batch. The smart buyer then matches the rating to use: IPX6 for jet spray and rafting, IPX7 for accidental immersion, IPX8 for deliberate submersion. Over-buying an IPX8 roll-top for daily rain adds cost and weight you do not need; under-buying IPX6 for whitewater leaves gear at risk.
Practical rating examples by activity
Map the rating to the activity before you buy or spec. Daily rain and commuter use need only IPX4 to IPX6 splash resistance, and a well-rolled roll-top comfortably exceeds it. Kayaking and boat spray sit at IPX6 to IPX7, matching rough spray and accidental one-metre immersion for 30 minutes. Snorkelling, diving and deliberate submersion demand IPX8 to a stated depth, usually on a sealed-lid or watertight-zipper design rather than an open roll-top.
The trap is trusting an open roll-top at depth: its rating describes accidental immersion, not pressure-sealed diving. When you compare SKUs, write down the rating digits, the stated depth and time, the closure type and the film gauge. That four-line spec prevents both over-paying for depth you will never use and under-protecting gear that one capsize would destroy. A rating without a stated depth is an unfinished claim.
The fine print: depth, time and what is not tested
Every waterproof rating hides fine print that changes the real-world meaning. IPX7 fixes the test at one metre of fresh water for exactly thirty minutes - it does not mean the bag can be worn snorkelling. IPX8 extends immersion beyond one metre, but the depth and duration are chosen by the manufacturer, so two IPX8 bags can mean three metres or twenty metres depending on the spec sheet. The X in IPX means the dust rating was never tested.
Always ask for three things: the rating digits, the stated immersion depth and time, and the date of the test report. A rating without a depth is an unfinished claim, and a report older than your current film batch is not evidence for your order. Then match the number to the activity - IPX6 for rough spray, IPX7 for accidental drops, IPX8 for deliberate submersion. Over-buying depth you will never use wastes money; under-buying it risks your gear.
Why these production numbers matter
For buyers evaluating this at production scale, the numbers that matter are concrete: a dedicated Quanzhou dry bag line running since 2014, a 4,950 square-metre facility on 7 production lines with 149 welding and sewing machines and about 137 trained operators, outputting roughly 200,000 pieces a month as verified by an SGS audit. Quality is backed by BSCI and ISO9001 systems, and finished orders ship DDP to over 100 countries. Those audited figures are what turn a well-written spec sheet into a repeatable supply of bags that actually keep gear dry, batch after batch, rather than a one-off sample that cannot be reproduced. For an importer, that repeatability is the difference between a launch that reorders smoothly and one that spends its first year chasing leaks and replacements.
