Use HS 3911.10 for petroleum resins expressly covered by that subheading, HS 3911.90 only for qualifying “other” products within heading 39.11, and HS 5503.90 for other unprocessed synthetic staple fibres such as PVA fiber. Those are international six-digit references. The importer must choose the destination’s full national code and confirm the live duty before shipment.
What each HS subheading actually covers
The WCO HS 2022 nomenclature divides the products as follows:
- 3911.10 — petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes. This is the direct starting point for C5, C9, C5/C9, DCPD-derived, and hydrogenated products that are objectively petroleum resins in primary form. Treatment such as hydrogenation does not by itself force a product into 3911.90.
- 3911.90 — other products of heading 39.11. This is a residual subheading covering other qualifying polymers named by heading 39.11 and Chapter 39 Note 3. Do not select it merely because “other” looks flexible; exact chemistry and national subheadings control.
- 5503.90 — other synthetic staple fibres, not carded, combed or otherwise processed for spinning. Construction PVA fiber normally enters this branch. Countries then add digits: examples include India and Vietnam 55039010 and Brazil 55039020 for polyvinyl-alcohol staple fibre.
A six-digit HS code creates a common international branch, not one global duty rate. India uses eight digits, Vietnam eight or ten, Türkiye twelve, the UAE twelve, and Brazil an eight-digit NCM. Ask the buyer’s broker to approve the full code against composition, form, processing, and intended declaration before the commercial invoice is finalized.
2026 import-duty snapshot for five markets
Snapshot date: 20 July 2026. Rates below are headline customs/import duties for China-origin commercial goods, not total landed tax. VAT/GST, India’s Social Welfare Surcharge, Brazil’s IPI/PIS/COFINS/ICMS, customs fees, safeguards, anti-dumping measures, exemptions, and special-use regimes are excluded.
| Market | 3911.10 petroleum resin | 3911.90 “other” | PVA line under 5503.90 | Practical qualification |
|---|---|---|---|---|
| India | 7.5% effective BCD on 39111090 | 7.5% effective BCD on 39119090 | 10% scheduled BCD on 55039010 | China has no general preference for these lines; SWS and 18% IGST are additional. |
| Vietnam | 0% ACFTA | 0% ACFTA | 0% ACFTA on 55039010 | Requires qualifying Chinese origin and valid Form E/accepted proof. Without preference, verify current MFN rates separately. |
| Türkiye | 6.5% on 391110000000 | 0–6.5% by national line; residual 391190990000 is 6.5% | 4% on 550390000000 | “Other countries” rate shown. Confirm the exact 12-digit GTİP and any current additional duty or trade remedy. |
| UAE | 5% | 5% | 5% | GCC common external tariff for ordinary foreign goods; verify the current 12-digit line and any exemption. |
| Brazil | 0% on NCM 39111021 for qualifying light-color hydrogenated resin; 12.6% on 39111029 “other” | 0–12.6% by NCM; 39119029 “other” is 12.6% | 0% on PVA-specific NCM 55039020 | The eight-digit NCM materially changes duty; several additional federal and state taxes still apply. |
This table is a screening aid, not customs advice or a tariff guarantee. Rates can change after publication, and a different formulation can map to another national line. Obtain written confirmation from the importer or licensed broker before pricing landed cost.
Non-dangerous-goods transport statement
Milorez MR-* petroleum resin and MF-* PVA fiber are supplied as non-dangerous goods. A grade-specific statement should identify the seller, exact product and grade, physical form, SDS revision date, and transport mode. For ocean freight, it should state that the product is not regulated as dangerous goods under the current IMDG Code and therefore has no UN number, dangerous-goods proper shipping name, hazard class, or packing group.
Also include package type, emergency contact, and the sentence that the cargo may be booked as ordinary/general cargo subject to carrier review. Do not use a generic letter to override the SDS, and do not write “non-hazardous under all laws.” Non-DG transport status does not remove normal dust control, storage, customs, or workplace-safety obligations.
Complete shipment document pack
- Commercial Invoice (CI): seller and buyer, invoice number/date, exact grade and description, full HS code, country of origin, quantity, unit price, total, currency, payment term, and Incoterms® 2020 rule with named port or place.
- Packing List (PL): package count and type, net/gross weight, dimensions or volume, pallet plan, shipping marks, and lot references. Totals must reconcile with the invoice and B/L.
- Bill of Lading (B/L): carrier transport document showing shipper, consignee, notify party, ports, vessel/voyage, packages, weights, marks, and freight status. Approve the draft before issue, especially under an L/C.
- Certificate of Analysis (COA): batch-specific results against agreed release properties. It should identify the shipped grade and lot; it is not a substitute for the TDS or SDS.
- Certificate of Origin (CO): non-preferential evidence of origin when the buyer, bank, or destination requires it. Agree the issuer and any legalization before document cut-off.
- Form E: preferential proof for a qualifying ASEAN-China FTA claim, particularly a Vietnam import. Classification, origin criterion, invoice details, route, and signatures must comply with the applicable rules.
- RCEP proof of origin: an alternative preference route for qualifying trade between RCEP members. Compare its product rule and rate with ACFTA; do not issue both casually or assume RCEP is better.
- Insurance certificate or policy: required when the sale term, contract, or L/C calls for it. Under CIF, check insured value, currency, voyage, risks, endorsements, and claims contact against the credit.
See the broader packaging and shipping plan for container loading and port arrangements.
Five document errors that delay clearance
- Declaring only six digits. The destination needs its national extension, which can change duty dramatically—especially Brazil’s PVA and hydrogenated-resin lines.
- Using inconsistent descriptions or codes. The CI, PL, B/L, CO, Form E/RCEP proof, COA, and labels must describe the same grade, origin, quantity, and packages.
- Writing “FOB” or “CIF” without the named port and version. Use, for example, “FOB Xiamen, Incoterms® 2020,” and align freight and insurance fields.
- Assuming an origin certificate guarantees preference. An ineligible product, failed origin rule, routing problem, late certificate, or data mismatch can invalidate the claim.
- Ignoring L/C wording until after sailing. Impossible document names, inconsistent tolerances, late presentation, and unapproved B/L clauses create discrepancies even when the cargo is correct.
Frequently asked questions
Is 3911.90 the normal code for hydrogenated petroleum resin?
No. Hydrogenation alone does not move petroleum resin out of 3911.10. Some countries create specific national lines for hydrogenated resin; Brazil’s NCM 39111021 is one example. Confirm the exact product and destination schedule.
Can the supplier make the final customs classification?
No. Milorez can provide composition, form, TDS/SDS, and a practical export reference, but the importer remains responsible for its declaration. Seek a destination ruling when the chemistry or national split is uncertain.
Are these products shipped with a dangerous-goods declaration?
No. MR-* resin and MF-* PVA fiber are non-dangerous goods with no UN number. Carriers may still request the current SDS and a non-DG statement before accepting ordinary-cargo booking.
Should a Vietnam buyer request Form E or RCEP proof?
Compare both routes before shipment. For the lines summarized above, ACFTA can provide 0% with valid Form E and qualifying origin. RCEP remains useful only when its eligibility, rate, and documentation fit the transaction.
What should a buyer send before document preparation?
Send the approved national HS code, consignee/notify details, tax identifiers, Incoterm and named port, origin-proof choice, B/L instructions, bank or L/C wording, legalization needs, and document deadlines. Request a shipment-ready quotation with these details.

Frequently asked questions
What is the HS code for petroleum resin?
HS 3911.10 is the international six-digit subheading that expressly covers petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes in primary forms. HS 3911.90 is the residual 'other' subheading within heading 39.11, not an automatic alternative for every hydrogenated or modified petroleum resin. Confirm the destination's full national code.
What is the HS code for construction-grade PVA fiber?
Construction-grade PVA staple fiber is generally classified within HS 5503.90: other synthetic staple fibres, not carded, combed or otherwise processed for spinning. National extensions can identify PVA specifically, such as 55039010 in India and Vietnam or 55039020 in Brazil. The importer should confirm the final national line.
Are Milorez petroleum resin and PVA fiber dangerous goods?
Milorez MR-* petroleum resin and MF-* PVA fiber are supplied as non-dangerous goods for transport, without a UN number. The current SDS and a grade-specific non-dangerous-goods statement should support the booking. Carrier acceptance and destination requirements still apply.
Does Form E automatically give a Vietnam shipment 0% duty?
No. The 0% ACFTA rate applies only when the tariff line is eligible, the goods satisfy the applicable origin and direct-consignment rules, and a valid Form E or accepted proof of origin matches the shipment. Vietnam Customs makes the final decision.
Which documents are normally required for a shipment?
The core set is commercial invoice, packing list, bill of lading and batch COA. Add the current SDS, any requested non-dangerous-goods statement, a non-preferential CO or qualifying Form E/RCEP proof, and an insurance certificate when the Incoterm, letter of credit or contract requires it.
