- Target (HS2022): Chapter 13
- Chapter title (JP, ref only): ラック、ガム、樹脂その他の植物性液汁及びエキス
- Country / practical assumption:Japan / Both (Import & Export)
- HS is harmonized at 6-digit level. Japan (like most countries) uses national tariff line codes beyond HS6 for declarations/statistics—treat those as national codes (not HS).
- Main assumed products & use cases (examples): shellac and natural resins for coatings/adhesives; gum arabic; botanical extracts for food/cosmetics; pectin and agar; guar/locust bean thickeners.
Sources used for HS scope and notes include WCO HS legal text extracts (HS2022/2017/2012/2007/2002). (世界税関機構)

0. Bottom line first: What is in / not in this Chapter (ultra-summary)
- Typical examples INCLUDED in this Chapter (3–6):
- Gum arabic (Acacia gum) in raw/refined form (HS6: 1301.20). (世界税関機構)
- Natural resins / gum-resins / oleoresins in crude form (e.g., frankincense, myrrh, dammar, mastic; shellac flakes as “lac”) (HS6: typically 1301.90). (世界税関機構)
- Botanical saps/extracts (e.g., liquorice extract, hop extract, aloe extracts, ephedra extract) (HS6: 1302.12 / 1302.13 / 1302.14 / 1302.19). (世界税関機構)
- Pectic substances (pectin) used as gelling agent/thickener (HS6: 1302.20). (世界税関機構)
- Agar-agar (HS6: 1302.31) and guar/locust bean plant-derived thickeners (HS6: 1302.32). (世界税関機構)
- Typical examples commonly EXCLUDED (3–6; include likely alternative Chapter/Heading):
- Liquorice extract that is sweetened beyond a specific threshold or put up as confectionery → typically Chapter 17 (1704). (The Chapter Note uses a 10% sucrose by weight threshold.) (世界税関機構)
- Coffee/tea/maté extracts → typically 2101 (not Chapter 13). (世界税関機構)
- Essential oils / concretes / absolutes / resinoids / extracted oleoresins → Chapter 33. (世界税関機構)
- Medicaments → 3003/3004; diagnostic reagents (e.g., blood-grouping reagents) → 3822 (note-driven exclusion). (世界税関機構)
- Tanning/dyeing extracts → 3201 / 3203. (世界税関機構)
- Natural rubber / similar natural gums (e.g., balata, gutta-percha, chicle) → 4001. (世界税関機構)
- The top practical decision points (1–3):
- Is it a crude vegetable sap/extract or plant-derived thickener vs a fragrance/essential oil preparation (often flips Chapter 13 ↔ Chapter 33). (世界税関機構)
- Is it still an “extract” vs a purified chemical isolate (often flips 1302 ↔ Chapter 29) or a medicament/diagnostic (often flips 1302 ↔ Chapter 30/38). (世界税関機構)
- For liquorice extract, confirm sugar addition/percentage and presentation (confectionery or not) (often flips 1302.12 ↔ 1704/2106). (世界税関機構)
- (Optional) Situations where misclassification tends to be “high-cost” in practice:
1. How to reach this Chapter (classification logic)
1-1. Core classification rules (where GIR matters)
- GIR 1 (start from wording + Notes):
For Chapter 13, the Chapter Note is a major “gatekeeper”: it explicitly tells you what stays in 13.02 and what must go elsewhere (sugar threshold, alcoholic beverage, essential oil type products, medicaments, etc.). (世界税関機構) - GIR 6 (choose the correct 6-digit subheading):
Once you’re sure it’s within 13.01 vs 13.02, GIR 6 pushes you into the right HS6 bucket (e.g., 1302.31 agar-agar vs 1302.39 other thickeners). (世界税関機構) - Perspectives to avoid “classifying by product name only”:
- Material/source: plant (or insect resin “lac”) source, and whether it’s derived from locust bean/guar vs other plants. (世界税関機構)
- How it was obtained: water extract vs solvent extract; presence of odoriferous fractions suggesting Chapter 33. (世界税関機構)
- Degree of purification: crude extract vs isolated compound (e.g., glycyrrhizin). (世界税関機構)
- Composition thresholds: sucrose % (for liquorice extract), alkaloid % (poppy straw concentrates). (世界税関機構)
Terms used consistently in this guide:
Chapter = 2-digit; Heading = 4-digit; Subheading = 6-digit; Section = grouping of Chapters; Notes = Section/Chapter Notes that legally steer classification.
1-2. Decision flow (pseudo flowchart)
- Step 1: Confirm the product family
- Step 2: Apply the Chapter 13 Note “exclusion tests”
- If it’s an essential oil/concrete/absolute/resinoid/extracted oleoresin → move to Chapter 33. (世界税関機構)
- If it’s a medicament or diagnostic reagent → move to Chapter 30/38. (世界税関機構)
- If it’s liquorice extract with >10% sucrose or confectionery presentation → move to 1704. (世界税関機構)
- If it’s natural rubber/chicle-like gum → move to 4001. (世界税関機構)
- Step 3: Pick HS6 within the Heading
- 13.01: gum arabic vs other
- 13.02: specific named extracts (opium/liquorice/hops/ephedra) vs other; then pectin vs agar vs other thickeners, etc. (世界税関機構)
- Common boundary disputes (e.g., boundary between Chapter X and Chapter Y):
2. Main Headings (4-digit) and what they cover
2-1. Table of key 4-digit Headings (REQUIRED)
- Rule:
- Chapter 13 has few Headings → list ALL. (Two headings: 1301, 1302.) (世界税関機構)
| Heading (4-digit) | Plain-English summary | Typical examples (products) | Key decision criteria / exclusions / cautions |
|---|---|---|---|
| 1301 | Natural gums/resins and similar resinous exudates (includes lac) | Gum arabic; shellac (lac) flakes; frankincense/myrrh; dammar/copal; balsams | Confirm it’s a natural gum/resin (not rubber in 4001; not a prepared adhesive/coating product). Gum arabic has its own HS6. |
| 1302 | Botanical saps/extracts and plant-derived gelling/thickening substances | Liquorice/hops/aloe/ephedra extracts; opium; pectin; agar-agar; guar/locust bean gums | Apply the Chapter Note exclusions: sugar threshold for liquorice; alcoholic beverage; essential oil/oleoresin products; isolated chemicals; medicaments/diagnostics; tanning/dye extracts; natural rubber. |
(Heading scope and HS6 structure per WCO HS2022 Chapter 13.) (世界税関機構)
2-2. Operationally important splits at the 6-digit Subheading level (REQUIRED)
Below are the most common “where the split happens” points that drive disputes.
Split group 1: 1301.20 (Gum arabic) vs 1301.90 (Other)
- Where the split happens:
- Gum arabic is singled out. Everything else in 13.01 goes to “Other”. (世界税関機構)
- Information needed to decide:
- Botanical source (Acacia species), common/technical name, and whether it is marketed as gum arabic.
- Specs: solubility, viscosity, typical COA items (ash, moisture) to support identity.
- Typical mistake pattern:
- Classifying other plant gums (e.g., tragacanth, karaya) as gum arabic because the invoice says “natural gum.”
Split group 2: 1302.12 (Liquorice extract) vs 1704 (Confectionery) / other food preparations
- Where the split happens:
- Liquorice extract can be in 1302.12, but if it exceeds a sucrose threshold or is presented as confectionery, it is excluded from 13.02. (世界税関機構)
- Information needed to decide:
- Sucrose % by weight (lab/COA), and how it’s packed/sold (bulk ingredient vs retail confectionery).
- Typical mistake pattern:
- Using the same HS code for both bulk liquorice extract (ingredient) and sweetened retail liquorice products.
Split group 3: 1302.13 (Hop extract) vs Chapter 33 (extracted oleoresins / odoriferous substances)
- Where the split happens:
- Chapter 13 covers “hop extract,” but the Chapter Note excludes extracted oleoresins/resinoids/essential-oil-type products into Chapter 33. (世界税関機構)
- Information needed to decide:
- Extraction method/solvent (water/ethanol vs CO₂), aroma fraction, and SDS/COA identifying “oleoresin” or odoriferous constituents.
- Typical mistake pattern:
- Classifying CO₂ hop oleoresin as 1302.13 just because commercial name includes “extract.”
Split group 4: 1302.20 (Pectin) vs other thickeners / “prepared food additives”
- Where the split happens:
- Pectin/pectinates/pectates are a dedicated HS6 bucket. (世界税関機構)
- Information needed to decide:
- Whether the product is truly pectin-based vs a blend (pectin + sugar + acids) marketed as “jam-setting mix”.
- Degree of modification (still pectin/pectinates/pectates or becomes a different chemical preparation).
- Typical mistake pattern:
- Treating any “gelling agent” as pectin, or classifying “pectin mixes” as pure pectin.
Split group 5: 1302.31 / 1302.32 / 1302.39 (plant-derived thickeners)
- Where the split happens:
- Agar-agar is separate (1302.31).
- Locust bean/guar thickeners are separate (1302.32).
- Everything else plant-derived goes to 1302.39. (世界税関機構)
- Information needed to decide:
- Source material (seaweed agar vs guar/locust bean vs other plant mucilages).
- “Whether or not modified” still stays here if it remains a plant-derived thickener.
- Typical mistake pattern:
- Mislabeling guar gum as agar, or classifying non-plant (microbial) thickeners as 1302.
3. Interpreting Section Notes and Chapter Notes (legal text → practical meaning)
3-1. Relevant Section Notes
- Key points (summary):
- In Section II, the term “pellets” is defined as agglomerated products made by compression or by adding a binder up to a small limit. (cbsa-asfc.gc.ca)
- Practical meaning (with concrete examples):
- If you import/export a plant-derived thickener that is pressed into pellets, it does not automatically change Chapters—classification still depends on the Chapter 13 headings/notes; “pellet” is mainly a form/condition definition.
- Typical patterns where a Section Note “moves you to another Chapter”:
- For Chapter 13 goods, the Chapter 13 Note is usually far more decisive than Section II notes.
3-2. Chapter Notes for this Chapter
- Key point’s (summary):
- The Chapter Note confirms that 13.02 covers certain well-known plant extracts (e.g., liquorice, hops, aloes, opium), but then lists multiple explicit exclusions. (世界税関機構)
- Definitions (if any):
- No “tight technical definition” is provided for all extracts; practical classification relies on product nature, composition, and exclusions.
- Exclusions (state alternative Chapter/Heading explicitly):
- Liquorice extract above a sucrose threshold / confectionery form → 1704. (世界税関機構)
- Malt extract → 1901; coffee/tea/maté extracts → 2101. (世界税関機構)
- Alcoholic beverages made from vegetable saps/extracts → Chapter 22. (世界税関機構)
- Camphor / glycyrrhizin / certain chemically defined products → 2914 / 2938 (depending on the substance). (世界税関機構)
- Poppy straw concentrates with ≥50% alkaloids → 2939. (世界税関機構)
- Medicaments → 3003/3004; blood-grouping reagents → 3822. (世界税関機構)
- Tanning/dye extracts → 3201 / 3203. (世界税関機構)
- Essential oils / concretes / absolutes / resinoids / extracted oleoresins / odoriferous preparations → Chapter 33. (世界税関機構)
- Natural rubber/balata/gutta-percha/guayule/chicle → 4001. (世界税関機構)
4. How the Chapter Notes change classification outcomes (where the code flips)
Purpose: make “note-driven splits” visible.
- Impact point 1: Liquorice extract + sugar threshold
- What to check (information needed):
- Sucrose % by weight; whether it is “put up as confectionery” (retail form). (世界税関機構)
- Evidence to collect in practice:
- COA/lab test showing sucrose %, ingredient list, product photos, packaging unit size, marketing use (ingredient vs confectionery).
- Typical misclassification:
- Declaring sweetened liquorice products as 1302.12 without checking the sugar threshold.
- What to check (information needed):
- Impact point 2: “Extract” vs essential oil / oleoresin / resinoid
- What to check (information needed):
- Extraction method (steam distillation / solvent / CO₂), whether product is primarily odoriferous, and whether it is described as oleoresin/resinoid. (世界税関機構)
- Evidence to collect in practice:
- SDS, manufacturing flow, COA showing volatile oil fraction, perfumery/cosmetic use documentation.
- Typical misclassification:
- Putting odoriferous extracts into 1302 instead of Chapter 33.
- What to check (information needed):
- Impact point 3: Extract vs isolated chemical constituent
- What to check (information needed):
- Is it a crude extract mixture, or a single isolated compound (e.g., glycyrrhizin)?
- Evidence to collect in practice:
- Purity %, analytical methods (HPLC), CAS number, SDS.
- Typical misclassification:
- Using 1302.12 for purified glycyrrhizin instead of the chemically defined chapter.
- What to check (information needed):
5. Common mistakes in practice (cause → correction)
- Mistake: Classifying CO₂ hop oleoresin as 1302.13 (“hop extract”)
- Why it happens:
- Commercial naming (“hop extract”) hides that it’s an extracted oleoresin/odoriferous product.
- Correct approach (which Note / which Heading logic supports it):
- Apply the Chapter Note exclusion for extracted oleoresins/resinoids/essential-oil-type products → likely Chapter 33, not 1302. (世界税関機構)
- Prevention (documents to verify / internal questions to ask):
- Ask for extraction method/solvent; obtain SDS/COA; confirm intended use (flavour/fragrance vs non-odoriferous extract).
- Why it happens:
- Mistake: Not checking sucrose % for liquorice extract
- Why it happens:
- Teams assume “liquorice extract = 1302.12” regardless of formulation.
- Correct approach:
- Confirm whether sucrose exceeds the Chapter Note threshold or product is “confectionery”; if so, move out of 13.02. (世界税関機構)
- Prevention:
- Require COA with sugar profile; keep a standard “sweetened vs unsweetened liquorice extract” checklist.
- Why it happens:
- Mistake: Classifying “agar plates” (prepared culture media) as 1302.31 agar-agar
- Why it happens:
- Agar is an ingredient, but the imported item is a prepared diagnostic/lab product.
- Correct approach:
- Agar-agar powder can be 1302.31, but prepared culture media/reagents typically classify in Chapter 38 (depending on the product). The Chapter Note already signals certain reagents are outside Chapter 13. (世界税関機構)
- Prevention:
- Confirm whether the product is pure agar vs a prepared medium; ask for product label and composition.
- Why it happens:
- Mistake: Treating any “gum” as 1301
- Why it happens:
- “Gum” is used for both resins and rubber-like materials.
- Correct approach:
- Check for natural rubber/chicle-like gums (excluded to 4001). (世界税関機構)
- Prevention:
- Ask: is it elastomeric rubbery material (NR) or water-soluble gum/resin?
- Why it happens:
- Mistake: Classifying purified glycyrrhizin as liquorice extract (1302.12)
- Why it happens:
- Same source plant; misunderstanding of “extract vs isolated chemical”.
- Correct approach:
- The Chapter Note excludes chemically defined products like glycyrrhizin to Chapter 29. (世界税関機構)
- Prevention:
- Require CAS number/purity; if purity is high and single compound, treat as chemical.
- Why it happens:
- Mistake: Classifying tanning/dye extracts as 1302
- Why it happens:
- They are “plant extracts,” but functionally tanning/dyeing.
- Correct approach:
- Chapter Note excludes tanning/dye extracts to 3201/3203. (世界税関機構)
- Prevention:
- Ask for end-use and industry (tanning/dye); check SDS and customer application.
- Why it happens:
- Mistake: Using a national tariff line code as if it were HS6 in FTA paperwork
- Why it happens:
- Systems output 9/10-digit codes; staff copy/paste into origin docs.
- Correct approach:
- Keep HS6 consistent for PSR selection; label longer codes as national tariff line codes.
- Prevention:
- Include a mandatory HS6 field in internal master data; keep a mapping table per country.
- Why it happens:
6. Points to watch for FTA/EPA origin certification
6-1. Relationship between HS classification and PSR (Product-Specific Rules)
- HS assignment drives PSR selection (misclassification breaks the origin analysis)
- If you choose the wrong Heading/Subheading, you may apply the wrong PSR, and your origin conclusion can fail in an audit.
- Common pitfalls
- Mixing up HS6 vs national tariff line codes.
- Applying PSR to the finished good in HS2022, while the agreement’s PSR annex is written in an older HS edition.
6-2. HS version differences referenced by agreements (HS2012 / HS2017 / HS2022)
Because the user did not specify agreements, below are Japan-relevant examples commonly encountered. Always confirm the HS edition stated in your specific agreement annex.
- CPTPP (example evidence): PSR tables are presented using HS 2012 classification. (グローバル外交カナダ)
- Japan–EU EPA (example evidence): PSR tables show Harmonized System classification (2017). (外務省)
- RCEP (example evidence): A transposed PSR in HS 2022 was adopted and implemented by Parties from 1 Jan 2023; Chapter 13 PSR lines are explicitly shown under HS2022. (外務省)
Practical cautions if the agreement’s HS edition differs from HS2022
- If your operational tariff classification is HS2022, but the agreement’s PSR annex is HS2012 or HS2017:
- Do not guess mappings.
- Map HS2022 → agreement HS edition using official correlation tables or agreement-issued transposition guidance.
- Keep an audit trail (why you mapped, which source). (General discipline per the provided FTA HS-edition guidance file.)
6-3. Practical checklist (data needed for origin analysis)
- Product & supply chain data
- HS6 for final good (and mapped HS edition code if needed)
- BOM (materials, origin for each, supplier statements)
- Manufacturing process steps and locations
- Costing/RVC worksheets if PSR requires it
- Supporting documents & retention (general guidance)
- Supplier declarations, COAs, SDS, process flow, invoices, production records
- Mapping evidence if HS edition differs (correlation tables, internal memo)
7. Differences between HS2022 and earlier HS editions (what changed and why)
7-1. Change summary (REQUIRED TABLE)
WCO legal text extracts for Chapter 13 show that the heading/subheading structure is unchanged from HS2017 to HS2022, but there is a note cross-reference update (a downstream impact from changes in other Chapters/Headings). (世界税関機構)
| Comparison (e.g., HS2017→HS2022) | Change type (new / deleted / split / merged / wording / scope) | Codes affected | Practical meaning of the change | Operational impact |
|---|---|---|---|---|
| HS2017→HS2022 | No structural change | 1301.20 / 1301.90 / 1302.11 / .12 / .13 / .14 / .19 / .20 / .31 / .32 / .39 | Same HS6 decision tree for gums/resins/extracts/pectin/agar/thickeners | Master data generally stable; still verify product facts vs Chapter Note exclusions |
| HS2017→HS2022 | Wording / cross-reference update in Chapter Note | Chapter 13 Note exclusion for blood-grouping reagents | Exclusion reference shifts from heading 3006 (HS2017) to 3822 (HS2022) | If you deal with diagnostic/reagent-type goods, cross-check Chapter 38/30 impact; otherwise low impact for typical Chapter 13 goods |
7-2. Why it changed (REQUIRED)
- Sources relied on:
- Explanation (basis and logic):
- Comparing the HS2017 and HS2022 Chapter 13 texts shows the HS6 list is the same, but the Note’s cross-reference for blood-grouping reagents is updated (reflecting where such goods are classified in the newer nomenclature). (世界税関機構)
8. HS codes added or removed before HS2022 (historical perspective)
Below is a high-level historical summary using WCO older-edition Chapter 13 extracts (HS2002/2007/2012/2017/2022). (世界税関機構)
| HS edition change | Change type | Codes affected | What happened | Practical “so what” |
|---|---|---|---|---|
| HS2002→HS2007 | Deleted | 1301.10 | HS2002 had a separate “lac” HS6; by HS2007, lac is no longer its own HS6 (falls under other within 13.01) | When you see legacy references to 1301.10, treat them as historical; use current HS6 |
| HS2002→HS2007 (and later) | Scope/structure change around 1302.14 | 1302.14 | HS2002 used 1302.14 for pyrethrum/rotenone roots; HS2007/2012 do not show 1302.14; HS2017/2022 show 1302.14 for ephedra | Be careful with old compliance documents: “1302.14” may refer to different products depending on HS edition |
| HS2017→HS2022 | Wording/cross-reference update | Chapter 13 Note | Blood-grouping reagent exclusion reference updated (3006 → 3822) | Mostly affects diagnostic/reagent goods and cross-chapter referencing |
9. Clearance trouble scenarios caused by violating Notes (case-style)
- Case 1: “Sweet liquorice paste” declared as 1302.12
- What went wrong (which Chapter Note / Section Note was violated):
- Liquorice extract exclusion based on sucrose threshold / confectionery presentation. (世界税関機構)
- Why it happens:
- Same supplier sells both bulk extract and sweetened retail items under the same product family name.
- Typical impacts:
- Post-entry correction; additional duty/tax; labeling/food compliance checks; delays.
- Prevention:
- Require COA (sucrose %) + packaging photos; pre-classification review; consider advance ruling for borderline products.
- What went wrong (which Chapter Note / Section Note was violated):
- Case 2: CO₂ hop oleoresin for brewing declared as 1302.13
- What went wrong:
- Chapter Note exclusion for extracted oleoresins/resinoids/essential-oil-type products. (世界税関機構)
- Why it happens:
- Commercial name includes “hop extract,” but technical profile is odoriferous oleoresin.
- Typical impacts:
- Reclassification to Chapter 33; origin rule changes; potential labeling differences.
- Prevention:
- Collect extraction method + SDS; confirm whether it’s treated as oleoresin/resinoid in trade.
- What went wrong:
- Case 3: “Jam-setting mix” declared as pure pectin (1302.20)
- What went wrong:
- Product is a preparation/blend rather than a pectic substance as such; may fall outside 1302.20 depending on composition/presentation (facts drive outcome). (世界税関機構)
- Why it happens:
- Purchasing uses ingredient name “pectin” while product is a blend (pectin + sugar + acids).
- Typical impacts:
- HS change impacts tariff and FTA PSR selection; food additive compliance review.
- Prevention:
- Obtain full formulation; decide whether it remains 1302.20 or becomes a food preparation (Information needed to decide: exact composition and use).
- What went wrong:
- Case 4: Prepared microbiology agar plates declared as 1302.31
- What went wrong:
- Product is a prepared lab medium/reagent (outside Chapter 13 in many cases); Chapter Note flags that certain reagents are excluded. (世界税関機構)
- Why it happens:
- The team classifies based on key material (agar) rather than product function and preparation.
- Typical impacts:
- Customs questioning; delays; potential import controls depending on reagent type.
- Prevention:
- Identify whether product is pure agar vs prepared diagnostic item; keep product label/IFU (instructions for use).
- What went wrong:
10. Import/export regulatory considerations (compliance)
For Japan, Chapter 13 goods can touch multiple regulatory axes depending on end-use and constituents. Requirements depend on specs/composition/end-use, so treat the points below as a screening checklist, not a definitive determination.
- Quarantine / sanitary & phytosanitary (SPS)
- Food use (pectin, agar, thickeners, extracts): Japan has an import notification framework under the Food Sanitation Act for foods/food additives and related items. (厚生労働省)
- Plant quarantine: raw plant materials can trigger plant quarantine; highly processed extracts may differ—verify based on product form and plant material status. Official plant quarantine information is maintained by MAFF Plant Protection Stations. (農林水産省)
- CITES / species restrictions
- If the material is derived from a CITES-listed species (certain plant resins/extracts can be implicated depending on the species), CITES permits/approvals may be required.
- Official verification points:
- Export controls (if applicable)
- Most Chapter 13 goods are not typical dual-use items, but some chemicals/extracts could be sensitive depending on end-use. METI provides general export control guidance. (経済産業省)
- Other permits / notifications
- Controlled substances / medicinal extracts: if your product contains controlled alkaloids or is treated as pharmaceutical ingredient, additional permits may apply (especially for opium-related goods). (Information needed to decide: active ingredient content, regulatory category, intended use.)
- Official places to verify (agencies / official guides / contact points):
- Japan Customs — advance rulings / classification consultation (税関ウェブサイト)
- MHLW — imported food safety / import procedure under Food Sanitation Act (厚生労働省)
- MAFF Plant Protection Station — plant quarantine inspections (農林水産省)
- CITES — Appendices and Japan national authorities (cites.org) METI — CITES (Japan) and export controls (経済産業省)
- Typical preparatory documents (general):
- COA (composition %, sugar profile where relevant), SDS, manufacturing flow, extraction method, intended use statement
- Invoice/packing list with clear product description (extract type, plant source, form)
- For CITES/special controls: permits/approvals and species documentation
11. Practical checklist (classification → clearance → origin → regulations)
- Before classification (collect product information)
- What is it exactly? (plant/insect source, part used, extraction method, solvent)
- Composition: sugar %, alcohol %, purity %, active constituents
- Form/presentation: bulk ingredient vs retail/confectionery; powder vs pellets vs liquid
- After classification (re-check Notes / exclusions / boundaries)
- Run the Chapter 13 Note “exclusion tests”:
- sugar threshold (liquorice)
- alcoholic beverage
- essential-oil-type products (Chapter 33)
- isolated chemicals (Chapter 29)
- medicaments/diagnostics (Chapter 30/38)
- tanning/dye extracts (Chapter 32)
- natural rubber/chicle-like gums (Chapter 40) (世界税関機構)
- Run the Chapter 13 Note “exclusion tests”:
- Before declaration (invoice description, units, supporting documents)
- Align commercial name with technical identity (avoid generic “plant extract”)
- Attach COA/SDS if the product is borderline (pre-empts questions)
- FTA/EPA checks (PSR, materials, processes, retention)
- Confirm the agreement’s HS edition (HS2012/2017/2022) and map if needed. (グローバル外交カナダ)
- Keep mapping evidence and process records for audit.
- Regulatory checks (permits/notifications/inspection)
