Sourcing dog poop bags from China
Dog poop bags from China carry a flat 6% UK duty across the relevant plastic-bag lines. Consumer products supplied in Great Britain must be safe, and environmental claims need supporting evidence. Specify the polymer, seals and roll fit before ordering. Cambridge China Bridge sources dog poop bags.

Dog poop bag duty depends on the plastic
Heading 3923 covers plastic articles for conveying or packing goods. For dog poop bags, the relevant lines distinguish polymers of ethylene from other plastics. Polyethylene bags use 3923 21 00 00; other plastic bags, excluding polyvinyl chloride, use 3923 29 90 00, subject to confirming the actual composition. The table repeats the polyethylene code for different bag formats.
Read from the UK Trade Tariff on 4 December 2026, both selected bag lines carry 6% duty for goods from China. Neither lists anti-dumping or countervailing duty or an attached import control. Both show narrowly defined suspensions: specialised multilayer damp-proof bags on the polyethylene line, and specified bioprocessing or hazardous-waste bags on the other-plastics line. These descriptions do not cover ordinary dog poop bags.
Confirm the resin blend and finished construction before choosing your commodity code. Assess Plastic Packaging Tax separately from customs duty, including the bags and their plastic packaging. Obtain component weights and material records. For wider pet sourcing, see pet beds.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Polyethylene dog poop bags on rolls | 3923 21 00 00 | 6% | None |
| Dog poop bags of other plastics, excluding polyvinyl chloride | 3923 29 90 00 | 6% | None |
Specify the film, tear line and dispenser fit
Specify the polymer blend, permitted recycled content, film thickness and tolerance, usable bag dimensions, gussets, seal position and tie handles. For rolls, agree bag count, winding direction, core dimensions, roll diameter and perforation position. Trial the approved roll in the dispenser you intend to sell or recommend.
Agree opacity, scent, opening effort and a leak-test method using a clean substitute load. Test separation at the perforation without tearing the next bag or opening its seal. Keep an approved sample and require approval before changes to resin, additives or film thickness.
Consumer products supplied in Great Britain must be safe. Include foreseeable suffocation risks in your safety review. Environmental claims need robust, credible, relevant and current evidence. Before approving biodegradable or compostable wording, request evidence for the finished bag and record the tested disposal conditions.
Worked duty example
Illustrative example, not a quote: Illustrative order of retail packs of polyethylene dog poop bag rolls under 3923 21 00 00, invoiced at £4,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £5,200. Duty at 6% is £312. Import VAT at 20% is charged on the customs value plus duty, £5,512, so it is £1,102.40. Import taxes total £1,414.40; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £312 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Film and seals: measure thickness and usable dimensions, inspect for pinholes and weak seams, and test leakage with the agreed clean substitute load.
Roll operation: check bag count, core and roll fit, winding direction, opening effort and separation along the perforations.
Handling: turn the bag inside out, pick up the substitute load, tie it closed and check for tearing around handles, gussets and seals.
Arrival and artwork: check moisture damage, stuck film layers, odour, print transfer and carton quantities. Match batch references, agreed contact details and environmental wording to the approved artwork and supporting records.

What goes wrong
An easy-tear perforation can cross a weak seal and open the next bag. Film that feels adequate on a roll may split when turned inside out or knotted. Oversized rolls jam dispensers, while tightly blocked film makes the bag difficult to open during a walk.
A factory may change the resin blend after sample approval, altering strength, smell or storage behaviour. A report for raw resin leaves the finished bag's environmental claim unresolved. Keep samples from production and arrival, and agree the inspection scope before shipment.
Cambridge China Bridge sources these products for UK businesses, checking the factory and the documents before shipment. See factory verification. For repeat volumes, see container programmes.
Frequently asked questions
What is the UK import duty on dog poop bags from China?
The selected polyethylene and other-plastic bag lines carry 6% duty. No anti-dumping or countervailing duty is listed. Their specialised suspensions do not cover ordinary dog poop bags.
Which commodity code covers dog poop bags?
Polyethylene bags use 3923 21 00 00. Other plastic bags, excluding polyvinyl chloride, use 3923 29 90 00. Confirm the finished bag's composition before declaring the code.
Can I sell the bags as biodegradable or compostable?
Environmental claims need robust, credible, relevant and current evidence. Request evidence matching the finished bag, and check the tested disposal conditions before approving the wording.
How should I test dog poop bag samples?
Use a clean substitute load to test pickup, inversion, knotting and leakage. Check perforations, opening effort and roll fit in the intended dispenser, then repeat these checks on production samples.
