HS 3915.10 — Plastic waste and scrap, of polymers of ethylene

3915.10 is waste, parings and scrap of plastics, of polymers of ethylene: the PE side of the plastic-waste heading. Film and bag scrap, bale offcuts, purge and regrind, process waste off an extrusion line.

How the heading is actually divided

Heading 3915 splits plastic waste four ways, and the variable is the polymer:

3915.10 Of polymers of ethylene · 3915.20 Of polymers of styrene · 3915.30 Of polymers of vinyl chloride · 3915.90 Of other plastics

Which produces a result worth knowing before you classify anything. PET, the most-traded plastic waste there is, has no six-digit line of its own. It falls into 3915.90, “of other plastics”, and only appears as a national statistical extension: in the United States it is reported at 3915.90.00.10, “Of polyethylene terephthalate (PET) plastics”, under the residual subheading. A buyer who assumes the HS code names the polymer at six digits is right for PE, PS and PVC and wrong for the one with the largest trade flow.

What the code does not tell you

Under US duty rates the four subheadings are identical: general rate Free, column 2 rate 10%, reported in kilograms. So on this heading the classification argument is almost never about money. It is about whether the consignment is allowed in.

And that question is decided somewhere else entirely. Singapore’s rules for importing plastic waste are scoped to HS code 3915 as a whole, and the test inside that scope is contamination:

• Annex IX types sit outside transboundary movement control
• other plastic waste types are held to 0.5% per bale
• the contaminant limits run 0% household and hazardous waste, 0.5% other recyclables, 2% water, 0.5% others, 2.5% total non-plastic contaminants

Not one of those thresholds has anything to do with whether the polymer is ethylene, styrene or vinyl chloride. The Basel Convention works the same way: the 2019 amendments put plastic waste into three places, Annex VIII A3210 where it is presumed hazardous, Annex IX B3011 where it is presumed not, and Annex II Y48 for everything in between, and the boundaries between them turn on contamination and on mixing, not on the subheading.

So the honest reading of 3915.10 is that it is a gate rather than an answer. It puts the consignment inside the controlled scope. Whether it may pass is a question for a laboratory report and a bale label.

What that does to the paperwork

A PE scrap consignment therefore travels with documents a finished-goods shipment of the same value would never need: an analytical report or surveyor’s inspection on contamination, per-bale weights on the packing list, bale labelling that matches the shipping documents, and, where the consignment is controlled, an import permit obtained before the goods ship, through the prior-informed-consent procedure, not after arrival.

That last ordering is the expensive one. A permit that has to exist before loading cannot be fixed at the port, and the box waits while it is sorted, which is where a documentation gap becomes terminal storage charges and then demurrage. The plastic waste import documents page sets out what a Singapore consignment under this heading has to carry, threshold by threshold.

Verify before you file

Subheadings below six digits are national. The four- and six-digit codes are harmonised under the WCO nomenclature, but the eight- and ten-digit extensions differ by country, as do the licences attached to them, and on this heading the licence matters far more than the rate. Confirm the national tariff line, the competent authority’s product code and the permit route with your customs broker for the specific destination before filing. In Singapore that is your declaring agent; in the UAE your clearing agent; in India the customs house agent.

What a desk can hold in advance is which evidence this lane needs, and chase it while the cargo is still at the supplier’s yard rather than after it is on the water. That is the work import document checking software does on a controlled-waste lane: the contract names the threshold, and every document that arrives is read against the others: the bale labels against the packing list, the declared polymer against the HS and product code, the analytical report against the specification that was bought.
